How do I render content already in graphics ram?

I wrote some really complex functions that are basically compute shaders. These compute shaders basically manage a huge ComputeBuffer containing voxel information.

I then Take either "portions of" or the whole voxel buffer in another compute shader and produce a vertex buffer (again all on the gpu).

Now I want to render that buffer but seemingly I must be looking in the wrong place.

Can anyone point me in the right direction to determine how I can render using a specified shader to output a buffer already in graphics ram (and ideally give it some textures too)?
