| | Heya, I just wanted some help with using vertex arrays. I wrote a Q3BSP map loader and this is the code that does the rendering, and it works as intended: [code=c++]glBegin(GL_TRIANGLES); for (int i = 0; i < curFace.meshVertexCount; i++) { int meshIndex = meshvertices[curFace.meshVertexOffset + i].offset; glVertex3fv(vertices[curFace.vertexOffset + meshIndex].position); … |
