Filter Kernels ⇨ Implement this easily on a GPU Supply filter kernel as uniforms Perform n 2 texture reads Apply kernel and write result ⇨ Perform n 2 texture reads! n larger than 4 or 5 won't work on most hardware Since the filter is a sum of products, it could be done in multiple passes 20-May-2009 © Copyright Ian D.
