108 | 109 | 110 | p(t)称为点A关于t的函数。Ray tracing的本质是通过发射射线，计算像素点的颜色。在ray tracing之前需要有个摄像机，建立坐标系，显示背景色，以及ray hit的点的颜色。 111 | 112 | 假设摄像机的位置就是眼睛位置，看到的内容为ppm显示的东西，简历坐标系，z轴正方向，垂直平面向外，x向右，y向上， 113 | 114 | 115 |
116 | 117 | 118 | 计算公式： 119 | 120 | blended_value = (1-t)*start_value + t*end_value 121 | 122 |
123 | 124 | 125 | ## Chapter4:Adding a sphere 126 | 127 | 球的公式： 128 | 129 | x*x + y*y +z*z = R*R 130 | 131 | 对于任意xyz，如果满足球面公式，(x,y,z)为球面的一个点。 132 | 133 | 如果球心位置为（cx,cy,cz）,公式为 134 | 135 | (x-cx)*(x-cx) + (y-cy)*(y-cy) + (z-cz)*(z-cz) = R*R 136 | 137 | 用向量表示，球面点P，球心点C，半径可以表示为向量PC 138 | 139 | dot((p-C)(p-C)) = (x-cx)*(x-cx) + (y-cy)*(y-cy) + (z-cz)*(z-cz) 140 | 141 | 等价于 142 | 143 | dot((A + t*B - C),(A + t*B - C)) = R*R 144 | 145 | 展开之后 146 | 147 | t*t*dot(B,B) + 2*t*dot(A-C,A-C) + dot(C,C) - R*R = 0 148 | 149 | ABC已知，这里是一个关于t的一元二次方程，对于t无解，有一个解，有两个解的情况，即为下图 150 | 151 |
152 | 153 | 154 | 通过打印颜色，利用红色的射线，ray hit 圆，hit到的地方显示红色 155 | 156 | ```c++ 157 | bool hit_sphere(const vec3 & center, float radius,const ray& r) 158 | { 159 | vec3 oc = r.origin() -center; 160 | float a = dot(r.direction(), r.direction()); 161 | float b = 2.0 * dot(oc,r.direction()); 162 | float c = dot(oc,oc) -radius*radius; 163 | float discriminant = b*b - 4*a*c; 164 | return (discriminant>0); 165 | } 166 | 167 | vec3 color(const ray& r) 168 | { 169 | if(hit_sphere(vec3(0,0,-1),0.5,r)) 170 | return vec3(1.0,0,0); 171 | 172 | vec3 unit_direction = unit_vector(r.direction()); 173 | float t = 0.5 *(unit_direction.y() + 1.0); 174 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 175 | } 176 | ``` 177 | 178 | 179 |
180 | 181 | 182 | ## Chapter5:Surface normals and multiple objects 183 | 184 | 法线是垂直与物体表面的一个向量，对于上一节提到的球，他的法线方向是，从球心出发，射向hitpoint的。就像在地球上，地面的法向是从地心出发，射向你站立的点的。 185 | 186 |
187 | 188 | 189 | 假设N是长度在[-1，1]之间的单位向量，映射到去见[0,1]之间，再映射x/y/z到r/g/b，通常除了须要知道是否hit点，还要拿到hit point的数据。 190 | 191 | ```C++ 192 | // 本章 hit_Sphere的返回值改为float了 193 | float hit_sphere(const vec3 & center, float radius,const ray& r) 194 | { 195 | vec3 oc = r.origin() -center; 196 | float a = dot(r.direction(), r.direction()); 197 | float b = 2.0 * dot(oc,r.direction()); 198 | float c = dot(oc,oc) -radius*radius; 199 | float discriminant = b*b - 4*a*c; 200 | if(discriminant<0) 201 | return -1.0; 202 | else 203 | return (-b-sqrt(discriminant))/(2.0*a); 204 | } 205 | 206 | vec3 color(const ray& r) 207 | { 208 | float t = hit_sphere(vec3(0,0,-1),0.5,r); 209 | if(t>0.0) 210 | { 211 | // 球心到hitpoint的单位法向量 212 | vec3 N = unit_vector(r.point_at_parameter(t)-vec3(0,0,-1)); 213 | return 0.5*vec3(N.x() +1,N.y()+1,N.z()+1); 214 | } 215 | 216 | vec3 unit_direction = unit_vector(r.direction()); 217 | t = 0.5 *(unit_direction.y() + 1.0); 218 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 219 | } 220 | 221 | ``` 222 | 223 | 224 |
225 | 226 | 当场景中有多个可以被击中的物体的时候，需要一个Hitable的抽象类，包含抽象方法hit 是否击中，以及记录hit到的数据，包括hit的位置，hit点的法向，以及距离t 227 | 228 | 通过距离t 229 | tmin< t < tmax 230 | 来控制hit到物体的距离远近，因为hit到之后将不再往后ray tracing。 231 | 232 | ```C++ 233 | #include "ray.h" 234 | 235 | struct hit_record 236 | { 237 | float t; 238 | vec3 p; 239 | vec3 normal; 240 | }; 241 | 242 | class hitable 243 | { 244 | public: 245 | virtual bool hit(const ray& r,float t_min,float t_max,hit_record & rec)const =0; 246 | }; 247 | ``` 248 | 249 | 对于sphere类基础hitable抽象类，实现自己的hit方法，去判断是否击中了球的对象 250 | 251 | ```C++ 252 | 253 | #include "hitable.h" 254 | 255 | class sphere: public hitable { 256 | public: 257 | sphere() {} 258 | sphere(vec3 cen, float r) : center(cen), radius(r) {}; 259 | virtual bool hit(const ray& r, float tmin, float tmax, hit_record& rec) const; 260 | vec3 center; 261 | float radius; 262 | }; 263 | 264 | bool sphere::hit(const ray& r, float t_min, float t_max, hit_record& rec) const { 265 | vec3 oc = r.origin() - center; 266 | float a = dot(r.direction(), r.direction()); 267 | float b = dot(oc, r.direction()); 268 | float c = dot(oc, oc) - radius*radius; 269 | float discriminant = b*b - a*c; 270 | if (discriminant > 0) { 271 | float temp = (-b - sqrt(discriminant))/a; 272 | if (temp < t_max && temp > t_min) { 273 | rec.t = temp; 274 | rec.p = r.point_at_parameter(rec.t); 275 | rec.normal = (rec.p - center) / radius; 276 | return true; 277 | } 278 | temp = (-b + sqrt(discriminant)) / a; 279 | if (temp < t_max && temp > t_min) { 280 | rec.t = temp; 281 | rec.p = r.point_at_parameter(rec.t); 282 | rec.normal = (rec.p - center) / radius; 283 | return true; 284 | } 285 | } 286 | return false; 287 | } 288 | ``` 289 | 290 | 还需要一个hitable list去记录击中所有的物体，也是继承hitable类，实现hit方法，去找出最近的物体。 291 | 292 | ```C++ 293 | 294 | #include "hitable.h" 295 | 296 | class hitable_list: public hitable { 297 | public: 298 | hitable_list() {} 299 | hitable_list(hitable **l, int n) {list = l; list_size = n; } 300 | virtual bool hit(const ray& r, float tmin, float tmax, hit_record& rec) const; 301 | hitable **list; 302 | int list_size; 303 | }; 304 | 305 | bool hitable_list::hit(const ray& r, float t_min, float t_max, hit_record& rec) const { 306 | hit_record temp_rec; 307 | bool hit_anything = false; 308 | double closest_so_far = t_max; 309 | for (int i = 0; i < list_size; i++) { 310 | if (list[i]->hit(r, t_min, closest_so_far, temp_rec)) { 311 | hit_anything = true; 312 | closest_so_far = temp_rec.t; 313 | rec = temp_rec; 314 | } 315 | } 316 | return hit_anything; 317 | } 318 | ``` 319 | 320 | 本章新的main函数如下 321 | ```C++ 322 | #include 323 | #include "sphere.h" 324 | #include "hitable_list.h" 325 | #include "float.h" 326 | 327 | using namespace std; 328 | 329 | 330 | vec3 color(const ray& r,hitable *world) 331 | { 332 | hit_record rec; 333 | if(world->hit(r,0.0,MAXFLOAT,rec)) 334 | return 0.5*vec3(rec.normal.x()+1,rec.normal.y()+1,rec.normal.z()+1); 335 | else 336 | { 337 | vec3 unit_direction = unit_vector(r.direction()); 338 | float t = 0.5 *(unit_direction.y() + 1.0); 339 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 340 | } 341 | } 342 | 343 | int main() 344 | { 345 | int nx =200; 346 | int ny=100; 347 | cout<<"P3\n"<=0;j--) 361 | { 362 | for(int i=0;i 382 | 383 | ## Chapter6:Antialiasing 384 | 385 | 真实世界中，照相机拍照时，一边边缘部分没有锯齿，因为每个像素，前景和背景在边缘的地方进行的混合。我们可以通过平均多个像素的值，达到一样的效果。我们的做法是，抽象camera类，后面再写颜色的部分。 386 | 387 | 还需要写个随机数的生成器，用来控制采样点的位置，范围是在[0,1]之间。这里我定义了一个宏 388 | 389 | #define random(a,b) (rand()%(b-a+1)+a) 390 | 391 | 使用rand()程序运行时每次生成的随机数和上一次相同，便于调试。 392 | 393 | 对于给的一个像素，我们有好几个采样点在像素内，对每个采样点进行ray tracer，再平均每个采样点的color。 394 | 395 | 396 |
397 | 398 | 399 | camera类 400 | ```c++ 401 | class camera 402 | { 403 | vec3 origin; 404 | vec3 horizontal; 405 | vec3 vertical; 406 | vec3 lower_left_corner; 407 | 408 | public : 409 | camera() 410 | { 411 | lower_left_corner = vec3 (-2.0,-1.0,-1.0); 412 | horizontal = vec3(4.0,0.0,0.0); 413 | vertical = vec3(0.0,2.0,0.0); 414 | origin = vec3(0.0,0.0,0.0); 415 | } 416 | 417 | ray get_ray(float u,float v) 418 | { 419 | return ray(origin,lower_left_corner+u*horizontal + v*vertical - origin); 420 | } 421 | 422 | }; 423 | ``` 424 | 425 | main函数 426 | ```C++ 427 | #include 428 | #include "sphere.h" 429 | #include "hitable_list.h" 430 | #include "float.h" 431 | #include "camera.h" 432 | #include "random" 433 | #define random(a,b) (rand()%(b-a+1)+a) 434 | 435 | using namespace std; 436 | 437 | vec3 color(const ray& r,hitable *world) 438 | { 439 | hit_record rec; 440 | if(world->hit(r,0.0,MAXFLOAT,rec)) 441 | return 0.5*vec3(rec.normal.x()+1,rec.normal.y()+1,rec.normal.z()+1); 442 | else 443 | { 444 | vec3 unit_direction = unit_vector(r.direction()); 445 | float t = 0.5 *(unit_direction.y() + 1.0); 446 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 447 | } 448 | } 449 | 450 | int main() 451 | { 452 | int nx =200; 453 | int ny=100; 454 | // 采样数量ns 455 | int ns = 100; 456 | cout<<"P3\n"<=0;j--) 470 | { 471 | for(int i=0;i 500 | 501 | 502 | ## Chapter7:Diffuse Materials 503 | 之前已经实现了多个object 和每个像素多个采样，本章将实现漫反射材质。首先需要明确的一点是，物体和材质的关系，我们假设球体有一个自己的材质，通常在渲染中，每个物体都有自己的材质。 504 | 505 | 不发光的物体，漫反射是吸收周围的颜色，显示出来，物体表面反射周围的光线的方向是随机的，如下图，在2个不同的物体的漫反射表面间，发射了3条光线，三条光线的漫反射之后的路径各不相同： 506 | 507 |
508 | 509 | 漫反射物体的表面，也可能会吸收部分光线，表面越暗，吸收的光线越多，吸收之后看起来就像一个哑光的表面。 510 | 511 | 选择一个随机的点切一个单位半径的球，这个点就是hitpoint，在球上选个随机点s，从p到s做一条线，作为漫反射的方向，这个球的球心是（p + N），N是hitpoitn的法向。 512 | 513 |
514 | 515 | 关于球面上s点如何区，这里的做法是，在单位cube中，选一个点，x、y、z都在[-1,1]之间，如果这个点不在球内，继续选点，直到满足在球内的这个条件。 516 | 517 | ```C++ 518 | // 单位cube随机取点,返回一个在球内的点 519 | vec3 random_in_unit_sphere() 520 | { 521 | vec3 p; 522 | do{ 523 | p = 2.0*vec3(random1,random1,random1) - vec3(1,1,1); 524 | }while (dot(p,p) >= 1.0); 525 | return p; 526 | } 527 | 528 | vec3 color(const ray& r,hitable *world) 529 | { 530 | hit_record rec; 531 | if(world->hit(r,0.0,MAXFLOAT,rec)) 532 | { 533 | vec3 target = rec.p + rec.normal + random_in_unit_sphere(); 534 | return 0.5* color(ray(rec.p, target - rec.p), world); 535 | } 536 | else 537 | { 538 | vec3 unit_direction = unit_vector(r.direction()); 539 | float t = 0.5 *(unit_direction.y() + 1.0); 540 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 541 | } 542 | } 543 | ``` 544 | 545 | 得到的图像如下： 546 |
547 | 548 | 球和地板的交界处的颜色可能不明显，是因为吸收的光太多了，可以通多将颜色开放的方法，来提高物体表面的亮度，减少吸收的光 549 | 550 | col = vec3(sqrt(col[0]),sqrt(col[1]),sqrt(col[2])); 551 | 552 | 这样就可以看清楚交界处的阴影效果了，如下图： 553 | 554 |
555 | 556 | ## Chapter8:Metal 557 | 对于不同的物体，可能有不同的材质，所以就需要设计一个材质抽象类，包含一些参数。对于程序而言，材质需要做的事情包括 558 | 559 | * 1.产生一个散射体（或者表示吸收了多少光线） 560 | * 2.如果发生散射，表达出光线应该衰减多少 561 | 562 | 抽象类如下： 563 | ```C++ 564 | class material { 565 | public: 566 | // 散射虚函数 567 | // 参数：r_in 入射的光线， rec hit的记录， attenuation v3的衰减，scattered 散射后的光线 568 | virtual bool scatter(const ray& r_in, const hit_record& rec, vec3& attenuation, ray& scattered) const = 0; 569 | }; 570 | ``` 571 | 572 | hitables 和material须要知道对方的数据，所以在c++代码中，hit_record中加了一个指针 * mat_ptr 指向material这个类。 573 | 574 | ```C++ 575 | struct hit_record 576 | { 577 | float t; 578 | vec3 p; 579 | vec3 normal; 580 | material *mat_ptr; 581 | }; 582 | ``` 583 | 584 | lambertian 材质，主要是漫反射，通过attenuation衰减，来控制散射之后的光线强度，散射的方向用random_in_unit_sphere()控制，albedo表示反射率 585 | 586 | ```C++ 587 | class lambertian : public material { 588 | public: 589 | lambertian(const vec3& a) : albedo(a) {} 590 | virtual bool scatter(const ray& r_in, const hit_record& rec, vec3& attenuation, ray& scattered) const { 591 | vec3 target = rec.p + rec.normal + random_in_unit_sphere(); 592 | scattered = ray(rec.p, target-rec.p); 593 | attenuation = albedo; 594 | return true; 595 | } 596 | 597 | vec3 albedo; // 反射率 598 | }; 599 | ``` 600 | 601 | 对于光滑表面的物体，ray不会随机的散射，物理规律是反射角等于入射角，会发生镜面反射，向量的说明如下： 602 | 603 |
604 | 605 | 红色的是反射光线，向量表示是(v+2B)，N是单位法向量，v是入射光线的方向向量，B的模是v和N的点乘 dot(v,N)。公式为： 606 | 607 | vec3 reflect(const vec3& v, const vec3& n) { 608 | return v - 2*dot(v,n)*n; 609 | } 610 | 611 | metal材质只反射光线，代码如下： 612 | ```C++ 613 | class metal : public material { 614 | public: 615 | metal(const vec3& a, float f) : albedo(a) { if (f < 1) fuzz = f; else fuzz = 1; } 616 | virtual bool scatter(const ray& r_in, const hit_record& rec, vec3& attenuation, ray& scattered) const { 617 | vec3 reflected = reflect(unit_vector(r_in.direction()), rec.normal); 618 | scattered = ray(rec.p, reflected + fuzz*random_in_unit_sphere()); 619 | attenuation = albedo; 620 | return (dot(scattered.direction(), rec.normal) > 0); 621 | } 622 | vec3 albedo; 623 | float fuzz; 624 | }; 625 | ``` 626 | 627 | 修改color方法，对散射进行递归，求color 628 | ```C++ 629 | 630 | vec3 color(const ray& r,hitable *world, int depth) 631 | { 632 | hit_record rec; 633 | if(world->hit(r,0.0,MAXFLOAT,rec)) 634 | { 635 | // 散射后的光线 636 | ray scattered; 637 | // 衰减 638 | vec3 attenuation; 639 | 640 | if(depth<50 && rec.mat_ptr->scatter(r,rec,attenuation,scattered)) 641 | { 642 | // 递归 衰减 643 | return attenuation * color(scattered, world, depth+1); 644 | } else 645 | { 646 | return vec3(0,0,0); 647 | } 648 | } 649 | else 650 | { 651 | vec3 unit_direction = unit_vector(r.direction()); 652 | float t = 0.5 *(unit_direction.y() + 1.0); 653 | return (1.0-t)*vec3(1.0,1.0,1.0) + t*vec3(0.5,0.7,1.0); 654 | } 655 | } 656 | ``` 657 | 658 | 再在场景中添加2个metal材质的球，main函数如下 659 | 注意因为加了hitrecord添加了material ，sphere的hit函数须要将hit_record的引用传出来，须要在函数内形参的指针指向material的matptr。 660 | ```C++ 661 | int main() 662 | { 663 | int nx =200; 664 | int ny =100; 665 | // 采样数量ns 666 | int ns = 100; 667 | cout<<"P3\n"<=0;j--) 682 | { 683 | for(int i=0;i 711 | 712 | 关于metal的反射，也可以用一个随机性的反射方向，来做微量的偏移，相当于一个小球上选endpoint。fuzzinss就相当于这个小球的半径，可以决定反射偏移的多少。fuzz取值在[0,1]之间 713 | 714 |
715 | 716 | 最后效果如下，注意两边的metal sphere中反射的边界模糊。 717 | 718 |
719 | 720 | ## Chapter9:Dielectrics 721 | 722 | 透明的物体，比如水，玻璃，钻石是电介质，当光射入的时候，不仅发生反射，还会发生折射。折射光线是ray tracer中比较难debug的部分。本章节在场景中放入了2个玻璃球，渲染出来的画面是这样的： 723 | 724 |
725 | 726 | 光从一种介质进入另一种介质时，实际上，有一部分光会折射进入另一种介质，有另一部分光则会反射回来。反射系数=反射光振幅（能量）/入射光振幅（能量）。 727 | 728 | 反射系数的求解是是一个非常复杂的过程，Christophe Schlick这个人提供一个逼近公式，这个公式被称为“ChristopheSchlick’s Approximation”。Wiki链接： 729 | 730 | https://en.wikipedia.org/wiki/Schlick%27s_approximation 731 | 732 | 当反射系数为0，只有折射，没有反射。 733 | 734 | 折射满足 斯涅尔定律（Snell law） 735 | 736 | n * sin(theta) = n' * sin(theat') 737 | 738 | 折射系数（air= 1,glass = 1.3-1.7, diamond = 2.4） 739 | 740 |
741 | 742 | 折射部分的代码如下： 743 | 744 | ```C++ 745 | bool refract(const vec3& v, const vec3& n, float ni_over_nt, vec3& refracted) { 746 | vec3 uv = unit_vector(v); 747 | float dt = dot(uv, n); 748 | float discriminant = 1.0 - ni_over_nt*ni_over_nt*(1-dt*dt); 749 | if (discriminant > 0) { 750 | refracted = ni_over_nt*(uv - n*dt) - n*sqrt(discriminant); 751 | return true; 752 | } 753 | else 754 | return false; 755 | } 756 | ``` 757 | 758 | 电解质材质总是会发生折射，所以材质类中派生dielectric类。 759 | 760 | ```C++ 761 | 762 | class dielectric : public material { 763 | public: 764 | dielectric(float ri) : ref_idx(ri) {} 765 | virtual bool scatter(const ray& r_in, const hit_record& rec, vec3& attenuation, ray& scattered) const { 766 | vec3 outward_normal; 767 | vec3 reflected = reflect(r_in.direction(), rec.normal); 768 | float ni_over_nt; 769 | attenuation = vec3(1.0, 1.0, 1.0); 770 | vec3 refracted; 771 | float reflect_prob; 772 | float cosine; 773 | if (dot(r_in.direction(), rec.normal) > 0) { 774 | outward_normal = -rec.normal; 775 | ni_over_nt = ref_idx; 776 | // cosine = ref_idx * dot(r_in.direction(), rec.normal) / r_in.direction().length(); 777 | cosine = dot(r_in.direction(), rec.normal) / r_in.direction().length(); 778 | cosine = sqrt(1 - ref_idx*ref_idx*(1-cosine*cosine)); 779 | } 780 | else { 781 | outward_normal = rec.normal; 782 | ni_over_nt = 1.0 / ref_idx; 783 | cosine = -dot(r_in.direction(), rec.normal) / r_in.direction().length(); 784 | } 785 | if (refract(r_in.direction(), outward_normal, ni_over_nt, refracted)) 786 | reflect_prob = schlick(cosine, ref_idx); 787 | else 788 | reflect_prob = 1.0; 789 | 790 | // 随机数小与反射系数，设为反射光线，反之为折射光线 791 | if (drand48() < reflect_prob) 792 | scattered = ray(rec.p, reflected); 793 | else 794 | scattered = ray(rec.p, refracted); 795 | return true; 796 | } 797 | 798 | float ref_idx; 799 | }; 800 | ``` 801 | 衰减始终是1，玻璃表面不吸收任何光线。 802 | 803 | 当场景中添加4个球，渲染出来的画面是这样的 804 | ```c++ 805 | list[0] = new sphere(vec3(0,0,-1),0.5,new lambertian(vec3(0.8,0.3,0.3))); 806 | list[1] = new sphere(vec3(0,-100.5,-1),100,new lambertian(vec3(0.8,0.8,0.0))); 807 | list[2] = new sphere(vec3(1,0,-1),0.5,new metal(vec3(0.8,0.6,0.2),0.3)); 808 | list[3] = new sphere(vec3(-1,0,-1),0.5,new dielectric(1.5)); 809 | ``` 810 | 811 |
812 | 813 | 如果对于电介质的球内部再加一个半径为 负的球，得到的效果如下（感觉是不同介质之间负负得正了）： 814 | 815 | ```c++ 816 | list[0] = new sphere(vec3(0,0,-1),0.5,new lambertian(vec3(0.8,0.3,0.3))); 817 | list[1] = new sphere(vec3(0,-100.5,-1),100,new lambertian(vec3(0.8,0.8,0.0))); 818 | list[2] = new sphere(vec3(1,0,-1),0.5,new metal(vec3(0.8,0.6,0.2),0.3)); 819 | list[3] = new sphere(vec3(-1,0,-1),0.5,new dielectric(1.5)); 820 | list[4] = new sphere(vec3(-1,0,-1),-0.45,new dielectric(1.5)); 821 | ``` 822 | 823 |
824 | 825 | ## Chapter10:Positionable camera 826 | 827 | 自由位置的camera，首先有了解FOV（Field of view）视场的概念，相当于视力看到的一定角度的内容。 828 | 829 | 从射线源点的位置，射向z=-1的平面，可以看到的高度h，满足： 830 | 831 | h = tan(theta/2) 832 | 833 |
834 | 835 | 修改camera部分的代码，增加fov 和aspect来控制可以看到的宽和高。 836 | 837 | 设置好camera的viewpoint之后，viewpoint就是lookfrom的点，看向的点就是lookat，还需要确定看过去水平方向的视野宽度，和竖直方向的视野宽度，camera所在平面竖直向上的向量"view up” vup，通过叉乘，拿到uvw，刚好相当于一个相机的坐标系。 838 | 839 | ```C++ 840 | class camera 841 | { 842 | vec3 origin; 843 | vec3 horizontal; 844 | vec3 vertical; 845 | vec3 lower_left_corner; 846 | 847 | public : 848 | camera(vec3 lookfrom, vec3 lookat, vec3 vup, float vfov, float aspect) 849 | { 850 | vec3 u,v,w; 851 | float theta = vfov*M_PI/180; 852 | float half_height = tan(theta/2); 853 | float half_width = aspect * half_height; 854 | origin = lookfrom; 855 | 856 | w = unit_vector(lookfrom - lookat); 857 | u = unit_vector(cross(vup, w)); 858 | v = cross(w,u); 859 | 860 | lower_left_corner = vec3 (-half_width,-half_height,-1.0); 861 | lower_left_corner = origin - half_width*u - half_height*v - w; 862 | horizontal = 2*half_width*u; 863 | vertical = 2*half_height*v; 864 | } 865 | 866 | ray get_ray(float u,float v) 867 | { 868 | return ray(origin,lower_left_corner+u*horizontal + v*vertical - origin); 869 | } 870 | 871 | }; 872 | 873 | ``` 874 | 875 | 876 | 877 |
878 | 879 | 设置新的摄像机，fov分别设置90和30°，得到的画面如下： 880 | 881 | 882 |
883 | 884 |
885 | 886 | 887 | 888 | ## Chapter11:Defocus Blur 889 | 890 | 散焦模糊（虚化），拍照的时候，我们经常会制造出虚化的效果，主题清晰，背景或者前景模糊，这是因为摄像机具有焦距，会有一个成像面，在有效焦距内的物体才能清晰成像，通过光圈控制进光量也可以控制虚化的范围。大光圈和长焦端，都可以制造出浅景深的效果。 891 | 892 |
893 | 894 |
895 | 896 | 本章引入aperture（光圈）,focus_dist(焦距) 2个参数，来实现画面的虚化效果。 897 | ```C++ 898 | 899 | class camera 900 | { 901 | vec3 origin; 902 | vec3 u,v,w; 903 | vec3 horizontal; 904 | vec3 vertical; 905 | vec3 lower_left_corner; 906 | float len_radius; 907 | 908 | public : 909 | camera(vec3 lookfrom, vec3 lookat, vec3 vup, float vfov, float aspect, float aperture, float focus_dist) 910 | { 911 | len_radius = aperture/2; 912 | float theta = vfov*M_PI/180; 913 | float half_height = tan(theta/2); 914 | float half_width = aspect * half_height; 915 | origin = lookfrom; 916 | 917 | w = unit_vector(lookfrom - lookat); 918 | u = unit_vector(cross(vup, w)); 919 | v = cross(w,u); 920 | 921 | lower_left_corner = origin - half_width*focus_dist*u - half_height*focus_dist*v - focus_dist*w; 922 | horizontal = 2*half_width*focus_dist*u; 923 | vertical = 2*half_height*focus_dist*v; 924 | } 925 | 926 | ray get_ray(float s,float t) 927 | { 928 | vec3 rd = len_radius * random_in_unit_disk(); 929 | vec3 offset = u * rd.x() +v*rd.y(); 930 | return ray(origin + offset,lower_left_corner+s*horizontal + t*vertical - origin - offset); 931 | } 932 | 933 | vec3 random_in_unit_disk() 934 | { 935 | vec3 p; 936 | do{ 937 | p = 2.0*vec3(drand48(),drand48(),0)-vec3(1,1,0); 938 | }while (dot(p,p)>=1.0); 939 | return p; 940 | } 941 | 942 | }; 943 | ``` 944 | 945 | 946 | 改变camera的参数，设置光圈和焦距 947 | ```C++ 948 | vec3 lookfrom(3,3,2); 949 | vec3 lookat(0,0,-1); 950 | float dist_to_focus = (lookfrom-lookat).length(); 951 | float aperture = 2.0; 952 | camera cam(lookfrom,lookat,vec3(0,1,0),20,float(nx)/float(ny),aperture,dist_to_focus); 953 | ``` 954 | 955 | 拿到的效果如下： 956 | 957 |
958 | 959 | ## Chapter12:Where next? 960 | 961 | 这张主要运用本书学到的知识，完成封面上的图片的渲染。 962 | 963 | 通过添加一个随机生成的世界，达到很多个小球的效果 964 | ```C++ 965 | 966 | hitable *random_scene() { 967 | int n = 500; 968 | hitable **list = new hitable*[n+1]; 969 | list[0] = new sphere(vec3(0,-700,0), 700, new lambertian(vec3(0.5, 0.5, 0.5))); 970 | int i = 1; 971 | for (int a = -11; a < 11; a++) { 972 | for (int b = -11; b < 11; b++) { 973 | float choose_mat = drand48(); 974 | vec3 center(a+0.9*drand48(),0.2,b+0.9*drand48()); 975 | if ((center-vec3(4,0.2,0)).length() > 0.9) { 976 | if (choose_mat < 0.8) { // diffuse 977 | list[i++] = new sphere(center, 0.2, new lambertian(vec3(drand48()*drand48(), drand48()*drand48(), drand48()*drand48()))); 978 | } 979 | else if (choose_mat < 0.95) { // metal 980 | list[i++] = new sphere(center, 0.2, 981 | new metal(vec3(0.5*(1 + drand48()), 0.5*(1 + drand48()), 0.5*(1 + drand48())), 0.5*drand48())); 982 | } 983 | else { // glass 984 | list[i++] = new sphere(center, 0.2, new dielectric(1.5)); 985 | } 986 | } 987 | } 988 | } 989 | 990 | list[i++] = new sphere(vec3(0, 1, 0), 1.0, new dielectric(2.5)); 991 | list[i++] = new sphere(vec3(-4, 1, 0), 1.0, new lambertian(vec3(0.4, 0.2, 0.1))); 992 | list[i++] = new sphere(vec3(4, 1, 0), 1.0, new metal(vec3(1, 1, 1), 0.0)); 993 | 994 | return new hitable_list(list,i); 995 | } 996 | ``` 997 | 998 |
999 | 1000 | 下一本书Peter Shirley-Ray Tracing The Next Week (2016) 将会从以下几个方面继续学习光追。 1001 | 1002 | * Motion Blur 1003 | 1004 | 运动模糊。跟上面的DOF一样，暴力多渲几帧，每帧用不同的位置就行。 1005 | * Bounding Volume Hierarchies 1006 | 1007 | 包围盒树。加速相交检测计算的。这方面另外有一大把更好的资料。 1008 | * 贴图 1009 | 1010 | 形状里定义好UV，然后用UV来采样贴图。当然采样方法有多种。 1011 | * Perlin Noise 1012 | 1013 | 柏林噪声。这里重点对采样结果做了Filtering，已经简单介绍了Turb（N重噪声产生的大理石纹理） 1014 | * 光源 1015 | 1016 | 把光源当成Emissive材质就搞定了。 1017 | * 物件的摆放 1018 | 1019 | 之前都是写绝对坐标的，这里在形状的体系里面加了一层Transform，只要通过那个Transform把Ray变换到物体的局部空间就可以像之前一样进行相交检测了。 1020 | * 体（Volume / Participating Media） 1021 | 1022 | 依然暴力的把Ray一点点插进Volume里面进行采样，每个采样点上取得Volume自身的颜色，并把Ray四散开去即可。 1023 | -------------------------------------------------------------------------------- /Peter-Shirley-Project
