The problem is that for the ply file that i have and the implementation that i did, there are small triangles spewed across …

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); …

I'm really frustrated right now because I've been looking all over the web on how to set up OpenGL to work with Microsoft Visual C++, but it seems like each website I find wants me to do something different. I feel like I'm missing something here...like I'm overcomplicating it. I …

I have heard you can efficiently use your GPU to do fast floating point calculations. This can be done using OpenGL but you may have to use the library in an unorthodox way or graphics card toolkits such as CUDA (by nVidia) which I guess is Graphics card specific. Does …
