I´m working on a terrain rendering using GPU-based clipmaps mentioned in GPU Gems.
In description of VBO an IBO is mentioned following
we can render the (x, y) geometries of all terrain blocks using a single read-only vertex buffer and index buffer, by letting the vertex shader scale and translate the block (x, y) geometry using a few parameters.
If I understand that correctly, than the entire terrain grid that is visible, should be stored in one VBO and IBO. Is that correct? I´m just asking because it sounds ´too much´?
Thank you in advance
