No, notice I use i + 1 as an index. The end - 1 prevents me reading past the end of the vertex array.

OK, my engine internally only deals with triangles internally. Whereas Quake 3 represents polys as triangle fans. That is why I break them down into triangles they are then easier to deal with.

I've tried replacing GL_TRIANGLE_FAN with GL_TRIANGLES and that didn't work (all maps became holey)
// If we're not using VBOs.if(!GLEE_ARB_vertex_buffer_object || map->mVertexBufferAssigned == false){ // Set the array of vertexes to draw. glVertexPointer(3, GL_FLOAT, sizeof(Q3Vertex), &(map->mVertexes[curFace.vertex].position));}// If we're using VBOs.else{ // Bind the VBO to use. glBindBuffer(GL_ARRAY_BUFFER, map->mVBOVertex); glVertexPointer(3, GL_FLOAT, 0, BUFFER_OFFSET(sizeof(float) * 3 * curFace.vertex));}// Draw all of the polygon elements.glDrawElements(GL_TRIANGLES, curFace.numMeshVerts, GL_UNSIGNED_INT, &(map->mMeshVerts[curFace.meshVert]));Quote:Original post by S8N
The map in question that I tried is rendering much more accurately now, there are still a couple of holes in the map but I think that is probably because I haven't coded any rendering for curved surfaces. [grin] Thanks for the help!
