Technical Evaluation of Traditional vs New "HDR" Encoding Crossed With...

Conclusion first. There is no technical justification for using the new HDR signal standards for HDR. Classic 8-bit/channel or 10-bit/channel Gamma 2.2 output is more than adequate for the full...

Possible Directional Routing Hoplite Variant?

Thinking about minimal grid based routing. Two things I don't like about the Hoplite, (1.) Full chip return paths.(2.) Route length not proportional to 2D locality. Like the simplified router and...

Atomic Scatter-Only Gather-Free Machines

GPUs are build around having texture caches, and caches are build around collecting loads for the most part, because loads have the highest memory traffic typically. So if after stripping out the...

Why Motion Blur Trivially Breaks Tone-Mapping - Part 2

Continuing from last post...The question remains how to "fix it"? Any "fix" requires that the post-tone-mapped image is physically energy conserving under motion blur. As in energy conserving from the...
