OBJ-3D Model Web Viewer with WebGL

To execute, open: "OBJ_Viewer.html".

Files:

• ./OBJ_Viewer.html - main web page, it handles the interface, shaders and the render.
• ./resources/object3d.js - Object3d prototype
• ./resources/material.js - Material prototype
• ./resources/gl-Matrix.js - Javascript Matrix and Vector library for High Performance WebGL apps, more information: http://glmatrix.net
• ./resources/loadOBJ.js - functions to read all the data from the MTL and OBJ files and initialize all the arrays, the main function is readOBJ.
• ./objs/* - directory with .obj examples

Limitations:

• The faces of the .obj meshes must be triangles, and they must include the face's normals.
• The viewer can't load textures yet.
• If the model is really big, you can appear inside the model and don't see it.
• If the materials from .mtl can't be loaded, the model will be seen with the default material, which is Blue.
• If the object has many polygons, the viewer can take a long time to load because the normals are calculated at the beginning.
