Is it possible to combine vertex buffers after they've been created? Here is my current situation: I have a quad which contains 2 triangles with 6 vertices. I want to tile this quad over a large area of 10x10 tiles. Instead of calling drawprimitives() 100 times, I am wondering if there's and easier way to combine all the tiles into a single vertex buffer so I only call drawprimitive() once. Suggestions? Thoughts? Spam?

No, You would have create a big one and memcpy them all in manually.

I wrote a wrapper for a Vertex Buffer that took care of this operation for you.

Bummer. Thanks anyway!

Just thought of something, one thing you could do is transfrom your vertices and bundle them into a vector. You can add vectors together and memcpy accross from it to the vertex buffer.

I'm using C# so I'll probably just manually transform them and then load them into a giant array before I create the Vertex Buffer. Fun times ahead for sure!
