Hello coders, Here is a screenshot of my very last work: real time quite high quality soft shadows on geforce class hardware, using no extensions.

Basically it is based on motion blurred shadows. I do so to be able to display many shadow volumes at the same time:
  • do not glclear alpha, do not use alpha for blending. Alpha is for shadows, nothing else, nah!
  • display shadow in alpha using the usual stencil volume
  • motion blur alpha
  • display quad as usually, using alpha buffer instead of stencil buffer
  • Other screenshots on my web site at:

    A demo can be downloaded at
