I wanted to experiment a bit with some simple SSAO (screen-space ambient occlusion), and some form of access to the depth buffer is needed for that. Is there a way to access the depth-buffer as image, e.g. to down- scale / blur it (separately from the colour-buffer)?
There's currently no way to access the Depth Buffer in QC out of the box. Even with plugins, it's a bit dodgy, simply because the layer ordering can make it difficult. (our GLTools plugin provides a "ReadPixels" patch that allows depth buffer reads, but it may not work on Snow Leopard?)
This would actually be a really rad extension to the Render In Image patch... ;)
