Is it possible to read from a texture in a vertex shader wi开发者_StackOverflow中文版th WebGL? I wrote a WebGL page (just to try it out) and used Chrome 7 to test it. As soon as I upgraded to Chrome
When parsing an .obj-file, with vertices and vertex-faces, it is easy to pass the vertices to the shader and the use glDrawElements using the vertex-faces.
I would like to draw you attention to the following pictures First the original image then how it is rendered on thescreen
don\'t worry, I don\'t want to ask how to use textures. :) My problem is: I\'m using several textures. But if I want to change the file name li开发者_运维问答ke this:
