getting started with vbo's

[noeska]

Now larger meshes also work.
Now i read that there is also a thing called buffers with indexed arrays. If i understand it correctly i do not need to feed all the vertexes even double but only the unique ones and pass indices to them. So like i do in gld3ds where i have a list of vertexes and a list containing indices to them.

so i need two vbo's one for the vertexes and one for the indices.

but how are these combined? Simple example anyone?

I suppose glDrawElements does that. (This doesn't make vbo of indices but does use vertices from vbo)

Example:
[pascal]type TN3DFaceIndices = array[0..2] of word;
var fa: array of TN3DFaceIndices;

glDrawElements(GL_TRIANGLES,Count*3,GL_UNSIGNED_SH ORT,@(fa[first]));
[/pascal]

Here was my version of performance test about Vertex arrays, displaylists and VBO all in 1:
