SPRITE EFFECTS Sample Clauses

SPRITE EFFECTS. A conditional write based on sprite pixel transparency is supported. Alpha blending per sprite pixel is supported, for effects such as translucency, shadows, and spotlights. Minimum blending functionality is (Source/2 + Destination/2) and (Destination - Source), while general blending is a multiply per R,G, and B component. A global alpha value can be multiplied by the sprite pixel alpha for fade and dissolve. Indexed color display drawing might use a palette of some number of hues, each of which has several intensity levels (such as 6 bits of hue and 2 bits of intensity), in order to support pixel blending by changing the intensity without changing the hue, for shadows, spotlights, and translucency.
