Shawn Hargreaves has published the third part of the series that cover "transitions", this time centering attention on the use of stencil buffers to produce some nice effects.

From the post: "... Stencil is usually an 8 bit integer value, and is attached to each pixel in addition to the usual color and depth values. You can set renderstates to control how values are written into the stencil buffer while drawing graphics, and also to specify that graphics should only be drawn in areas where the existing stencil values meet specified conditions ...".

Consice, accurate and practical. The best part on the series so far, imho of course ... cheers!
