/1/readme.md: -------------------------------------------------------------------------------- 1 | # Assignment 1 2 | 3 | ## Task: 4 | 5 | 1. **[MUST]** Given three 3D points, fill transformation matrices and then make points show on screen. 6 | 2. **[OPTIONAL]** Rotate points around any axis through origin. 7 | 8 | **Key words**: Transformation, rasterization. 9 | 10 | PPT: 3-5. 11 | 12 | ## Recall: 13 | 14 | 1. MVP transformation: Model, view, projection. 15 | 2. Derivation of rotation formula: use (r, theta). 16 | 3. View: 17 | 1. Camera on origin, look at -Z. 18 | 2. Rotate around any axis. Rodrigues’ Rotation Formula. 19 | 4. Projection: orthographic(正交) projection, perspective(透视) projection. 20 | 1. Orthographic projection: make all points in [-1,1]^3. 21 | 2. Perspective projection: covert to orthographic projection. 22 | 1. Near plane point's coordinate don't change, as do those on far plane. 23 | 5. Field-of-view: angle. Aspect ratio: width/height. 24 | 25 | -------------------------------------------------------------------------------- /2/CMakeLists.txt: -------------------------------------------------------------------------------- 1 | cmake_minimum_required(VERSION 3.10) 2 | project(Rasterizer) 3 | 4 | find_package(OpenCV REQUIRED) 5 | 6 | set(CMAKE_CXX_STANDARD 17) 7 | 8 | include_directories(/usr/local/include) 9 | 10 | add_executable(Rasterizer main.cpp rasterizer.hpp rasterizer.cpp global.hpp Triangle.hpp Triangle.cpp) 11 | target_link_libraries(Rasterizer ${OpenCV_LIBRARIES}) 12 | -------------------------------------------------------------------------------- /2/Triangle.cpp: -------------------------------------------------------------------------------- 1 | // 2 | // Created by LEI XU on 4/11/19. 3 | // 4 | 5 | #include "Triangle.hpp" 6 | #include 7 | #include 8 | 9 | 10 | Triangle::Triangle() { 11 | v[0] << 0,0,0; 12 | v[1] << 0,0,0; 13 | v[2] << 0,0,0; 14 | 15 | color[0] << 0.0, 0.0, 0.0; 16 | color[1] << 0.0, 0.0, 0.0; 17 | color[2] << 0.0, 0.0, 0.0; 18 | 19 | tex_coords[0] << 0.0, 0.0; 20 | tex_coords[1] << 0.0, 0.0; 21 | tex_coords[2] << 0.0, 0.0; 22 | } 23 | 24 | void Triangle::setVertex(int ind, Vector3f ver){ 25 | v[ind] = ver; 26 | } 27 | void Triangle::setNormal(int ind, Vector3f n){ 28 | normal[ind] = n; 29 | } 30 | void Triangle::setColor(int ind, float r, float g, float b) { 31 | if((r<0.0) || (r>255.) || 32 | (g<0.0) || (g>255.) || 33 | (b<0.0) || (b>255.)) { 34 | fprintf(stderr, "ERROR!

[Wiki](https://en.wikipedia.org/wiki/Signed_distance_function). 17 | 2. Explicit. Point cloud, polygon mesh ... Curve and surface. 18 | 2. Curves. Bezier Curves. De Casteljau Algorithm. 19 | 1. Quadratic: Let's $t \in [0, 1]$ , choose point S on AB that |SA|=t|AB|, choose point T on BC that |TB|=t|BC|, then choose point P on ST that |PS|=t|ST|. 20 | 2. Cubic: Four input points. 21 | 3. Let's $b_i^t$ is i-th point in t-th layer(both t, i's index from 0). $b_0^n$ is component by $b_i^0$ with Bernstein polynomials with unknown number t. 22 | 4. Properties: 23 | 1. Interpolates endpoints. $b(0)=b_0^0, b(1) = b_n^0$ . 24 | 2. Tangent tp end segments. 25 | 3. Affine transformation. 26 | 4. Curve is within convex hull of control points. 27 | 5. Piecewise Bezier Curves. Continuity. 28 | 3. Surfaces. 29 | 1. Bezier surfaces. 1-D's extension. 30 | 2. Mesh operations. 31 | 1. Mesh subdivision. Create then tune. 32 | 1. Catmull-Clark Subdivision. 33 | 2. Mesh simplification. Edge collapsing. New vertex should minimize its sum of L2 distance. 34 | 3. Mesh regularization. 35 | 4. Shadow mapping. 36 | 1. Key idea: the points not in shadow mush be seen with both by the light and by the camera. 37 | 2. Get depth image from light, then render from eye. 38 | 3. Problems 39 | 1. Hard shadows(point lights only) 40 | 2. Quality depends on shadow map resolution. 41 | 3. Equality comparison between float number. 42 | 43 | ## Code: 44 | 45 | Antialiasing, two methods: 46 | 47 | 1. $\sum_i 255 \times \max(2-\exp(dist_i), 0)$ 48 | 2.

Metropolis Light Transport (MLT) : Markov Chain Monte Carlo, locally. 20 | 2. Biased: 21 | 1. Photon Mapping (光子映射) : Specular-Diffuse-Specular (SDS). Firstly emit photons from the light source, stop on diffuse surfaces, then shoot sub-paths from the camera, hit on diffuse surfaces. 22 | 2.

It is easy 9 | to integrate into existing applications and does not lay claim to the main loop. 10 | 11 | See @ref news_31 for release highlights or the 12 | [version history](http://www.glfw.org/changelog.html) for details. 13 | 14 | @ref quick is a guide for those new to GLFW. It takes you through how to write 15 | a small but complete program. For people coming from GLFW 2, the @ref moving 16 | guide explains what has changed and how to update existing code to use the new 17 | API. 18 | 19 | There are guides for each of the various areas of the API. 20 | 21 | - @ref intro – initialization, error handling and high-level design 22 | - @ref window – creating and working with windows and framebuffers 23 | - @ref context – working with OpenGL and OpenGL ES contexts 24 | - @ref monitor – enumerating and working with monitors and video modes 25 | - @ref input – receiving events, polling and processing input 26 | 27 | Once you have written a program, see the @ref compile and @ref build guides. 28 | 29 | The [reference documentation](modules.html) provides more detailed information 30 | about specific functions. 31 | 32 | There is a section on @ref guarantees_limitations for pointer lifetimes, 33 | reentrancy, thread safety, event order and backward and forward compatibility. 34 | 35 | The @ref rift fills in the gaps for how to use LibOVR with GLFW. 36 | 37 | The [FAQ](http://www.glfw.org/faq.html) answers many common questions about the 38 | design, implementation and use of GLFW. 39 | 40 | Finally, the @ref compat guide explains what APIs, standards and protocols GLFW 41 | uses and what happens when they are not present on a given machine. 42 | 43 | This documentation was generated with Doxygen. The sources for it are available 44 | in both the [source distribution](http://www.glfw.org/download.html) and 45 | [GitHub repository](https://github.com/glfw/glfw). 46 | 47 | */ 48 | -------------------------------------------------------------------------------- /8/CGL/deps/glfw/src/glfw3.pc.in: -------------------------------------------------------------------------------- 1 | prefix=@CMAKE_INSTALL_PREFIX@ 2 | exec_prefix=${prefix} 3 | includedir=${prefix}/include 4 | libdir=${exec_prefix}/lib@LIB_SUFFIX@ 5 | 6 | Name: GLFW 7 | Description: A multi-platform library for OpenGL, window and input 8 | Version: @GLFW_VERSION_FULL@ 9 | URL: http://www.glfw.org/ 10 | Requires.private: @GLFW_PKG_DEPS@ 11 | Libs: -L${libdir} -l@GLFW_LIB_NAME@ 12 | Libs.private: @GLFW_PKG_LIBS@ 13 | Cflags: -I${includedir} 14 | -------------------------------------------------------------------------------- /8/CGL/deps/glfw/src/glfw3Config.cmake.in: -------------------------------------------------------------------------------- 1 | # - Config file for the glfw3 package 2 | # It defines the following variables 3 | # GLFW3_INCLUDE_DIR, the path where GLFW headers are located 4 | # GLFW3_LIBRARY_DIR, folder in which the GLFW library is located 5 | # GLFW3_LIBRARY, library to link against to use GLFW 6 | 7 | set(GLFW3_VERSION "@GLFW_VERSION_FULL@") 8 | 9 | @PACKAGE_INIT@ 10 | 11 | set_and_check(GLFW3_INCLUDE_DIR "@PACKAGE_CMAKE_INSTALL_PREFIX@/include") 12 | set_and_check(GLFW3_LIBRARY_DIR "@PACKAGE_CMAKE_INSTALL_PREFIX@/lib@LIB_SUFFIX@") 13 | 14 | find_library(GLFW3_LIBRARY "@GLFW_LIB_NAME@" HINTS ${GLFW3_LIBRARY_DIR}) 15 | 16 | -------------------------------------------------------------------------------- /8/CGL/deps/glfw/src/iokit_joystick.h: -------------------------------------------------------------------------------- 1 | //======================================================================== 2 | // GLFW 3.1 IOKit - www.glfw.org 3 | //------------------------------------------------------------------------ 4 | // Copyright (c) 2006-2014 Camilla Berglund 5 | // 6 | // This software is provided 'as-is', without any express or implied 7 | // warranty.
