The index buffer contains integers, three for each triangle in the mesh, which reference the various attribute buffers (position, colour, UV coordinates, other UV coordinates, normal, …). It’s a little bit like in the OBJ file format, with one huge difference : there is only ONE index buffer. pop thank you https://jezroc.com

After binding the normal buffer OpenGL does not draw anymore.

Web14 de jun. de 2015 · If you want to have indexing with texture coordinates and normals, then you have 2 options: Export the .obj so that it has all the duplicates already (a.k.a. baking) (I believe you can set this up in 3ds max GW obj exporter by disabling "optimize") Do this duplicating of vertices in your own code. WebUsing normals when drawing with element buffer. If I want to draw a simple cube using element buffer, normally I could load in just the eight vertices into vertex buffer and … WebUsing vertex normals in OpenGL To use normals in OpenGL, it’s very easy. A normal is an attribute of a vertex, just like its position, its color, its UV coordinates… so just do the usual stuff.
