dom3d: rendering 3d with CSS3

44 | 45 |

46 | Fork me on github! 47 |

48 | 49 |

50 | 51 | James Long works 52 | for Mozilla and can be reached at 53 | jlongster@jlongster.com 54 | 55 |

56 | 57 |

58 | Here is a 3d object. It is rendered with pure HTML and CSS 59 | using 2d 60 | transforms. These let you specify a transform 61 | property on a DOM element composed 62 | of translate, rotate, 63 | skew, and scale functions. 64 |

65 | 66 |

67 | To achieve the 3d effect, I project the 3d triangles into 2d 68 | screen space using javascript, and then calculate the necessary 69 | transform value to display the 2d triangle. 70 | 71 |

72 | 73 |
74 |
75 | CSS Effects: 76 |
Border
77 |
Off
78 |
Stop
79 | 80 | 
.off:nth-of-type(2n) {
 81 |     top: 100px;
 82 |     opacity: 0;
 83 |     -moz-transition: all 2s;
 84 | }
85 |
86 | 87 |

88 | So without any SVG or canvas, you can have real-time 3d objects 89 | in modern browsers! What's the benefit? Well, you don't have to 90 | deal with a canvas, and you can click on links underneath 91 | it. Maybe this is just a cool hack, maybe not? 92 |

93 | 94 |

What's the point?

95 | 96 |

97 | This is mainly just a cool hack, but I think there's use cases 98 | for quick 3d effects on websites. There are a few benefits to this 99 | approach: you get to manipulate the elements with normal CSS, 100 | and you can overlay 3d objects onto pages and still let the 101 | user interact with the page. 102 |

103 | 104 |

105 | I'm interested to see what others think of this hack and see 106 | how far it can go. I'd like to see this library turn into a 107 | quick 3d effects library that supports HTML/CSS, SVG, canvas, and webgl. 108 |

109 | 110 |

How's it work?

111 | 112 |

113 | A 2d triangle is really a quad, but imagine cutting the quad 114 | from two opposite corners and taking only the left 115 | triangle. That's essentially what I do, by way of the CSS3 background 116 | linear-gradient 117 | property. It aligns the background with two opposite corners and 118 | makes one side completely transparent. 119 |

120 | 121 |

122 | Here's an example (only showing the -moz properties, but dom3d 123 | supports -webkit and -o too): 124 | 125 | 

background-image: -moz-linear-gradient(-45deg, red 50%, transparent 0);
126 | 127 |
128 |
129 |

130 | 131 |

132 | It turns out that you can render any 2d triangle with the 133 | right translate, rotate, skew, 134 | and scale 135 | settings for the transform CSS property. 136 | 137 |

-moz-transform: skew(30deg);
138 |
-moz-transform: rotate(50deg) skew(-30deg) scale(1.5, .7);
139 |
140 |

141 | 142 |

143 | So you just have to project all the 3d triangles onto the 2d 144 | screen space, and manipulate the DOM triangles to render them 145 | according to the 2d coordinates. 146 |

147 | 148 |

149 | Here is example CSS from a rendered triangle: 150 | 151 | 

152 |           -moz-transform: translate(442.176px, 306.35px) rotate(2.12662rad) skew(2.7961rad) scale(197.767, 180.506);
153 |           background: -moz-linear-gradient(45deg, rgb(87, 111, 121) 50%, transparent 0pt);
154 |
155 |

156 | 157 | 158 |

Notes

159 | 160 |

161 | CSS3 isn't fully supported yet across all browsers, but dom3d 162 | supports Firefox, Chrome, Safari, and Opera. I think IE9 163 | support is possible too. 164 |

165 | 166 |

167 | Obviously there are issues with seams. This is due to 168 | anti-aliasing that is done on the edges. Different browsers 169 | have slightly different effects. 170 |

171 | 172 |

173 | In Firefox 4, there is also a glitch where if I re-use DOM 174 | elements between frames, you can see the other edge of the DOM 175 | elements briefly. The example above creates new DOM elements 176 | per frame, but if you turn on any of the options to the right 177 | it'll switch to re-using DOM nodes and you'll see the 178 | effect. Firefox 6 (nightly) does not have this glitch. 179 |

180 | 181 |

182 | Various browsers will have glitches with this hack, as it's 183 | really a severe and gross hack. Or maybe just a good test case? 184 |
