Introduction I wrote a DX11 DirectCompute implementation of the famous global operator photographic tonemapping algorithm developed by Erik Reinhard, Mike Stark, Peter Shirley and Jim Ferwerda. My code is based on the original code provided by the authors at http://www.cs.utah.edu/~reinhard/cdrom/. As in the sample source, my implementation performs tonemapping on luminance values in the Yxy [...]

Introduction Following in the footsteps of other people on the Internet, I’ve written a GPGPU language Mandelbrot fractal viewer. Along with a DirectCompute implementation, I’ve also written a reference unoptimized cpu version and am really excited that the DirectCompute implementation is more than 50x times faster! (With the caveat that my cpu implementation can probably [...]
