In part one of this two-part post, I wrote about the first part of Tom Olson's paper from High Performance Graphics 2012. We saw how Bounded Integer Sequence Encoding allows ASTC to have a finely graded tradeoff between the roles of bits in a block. In this part, we will learn about the other techniques that contribute to ASTC’s flexibility and quality. Partitioning the Color Space Sometimes, the colors in a block do not fit neatly along one line. In an image of a red ball resting on green grass, blocks at the edge of the ball will...
