It has been a while since I last used Vertex Buffer Objects (VBO) with LWJGL. It seemed as if they had changed some of the method signatures since I used them last time. I couldn’t even get the simplest example running. After experimenting for a while I finally figured it out. Have a look at the signature of the VertexPointer method:

static void glVertexPointer(int size, int type,
  int stride, long pointer_buffer_offset);

With the last offset one can specify where the vertex information starts in the buffer given to the VBO management. Well, I could/should have guessed that this offset has to be in bytes since I am dealing with a buffer here but instead I used the number of floats.. So next time I see an operation dealing with buffers that takes a long argument I’ll try the byte-count from the beginning..
