PLY 3D model viewer based on HTML5 canvas

3D HTML5 canvas realization based on 2D and WebGL context.

Examples:

• 2D: Cube (see Cube function in source code)
• 2D: Suzanne monkey
• 2D: Utah teapot
• WebGL: Suzanne monkey
• WebGL: Utah teapot

Features:

• 3D operations: rotating, moving object center
• Ambient light (only WebGL)
• Directional light
• Perspetive camera (only WebGL)
• Highlighting edges (only 2D)
• Painter's algorithm for sorting polygons (only 2D)
• Optimizations (only 2D): Skip processing of invisible polygons, skip processing of duplicated points, normals

Requirements for 2D:

• Internet Explorer 9
• Chrome 4.0
• Firefox 2.0
• Safari 3.1, mobile Safari 3.2
• Opera 9.0, mobile Opera 10.0
• Android Browser 2.1

Requirements for WebGL:

• Chrome 9.0
• Firefox 4.0
• Safari 5.1 (needs to be enabled in Options)
• Opera 12.0

Warning! canvas-ply-reader.html and webgl-ply-reader.html won't work from disk because it uses AJAX to load .ply model file.
