I'm really REALLY loving the Dissolve shader! This is good ol' color cycling with transparency added for the dissolve effect! Me, I'm mostly interested in pure color cycling, which I can get by simply removing the transparency from Ramp.png and give it some crazy color gradients.
SP_Dissolve_SetThreshold() shifts Ramp.png back and forth along the grey values. So if you let the value change gradually in the do loop, it will give that shimmering color cycling animation. (It seems like the value goes from 0.0 to 1.0)
I'm not entirely sure about the command
SP_Dissolve_SetSize(ObjectID,Size#). It seem to shift how Ramp.png is mapped to Dissolve.jpg or something?
Also not sure about
SP_Dissolve_AddMesh(ObjectID,MeshID,DiffuseImageID,MaskImageID,RampImageID)
I tried expanding Ramp.png in the X direction, from 128 to 1024 pixels. Seem to work, but I don't know if I'm supposed to do that.
So far, I'm mostly playing around with editing Ramp.png and Dissolve.jpg, creating wacky effects.
The most committed use of color cycling I have ever seen is found in the game ENDORFUN. Back in the nineties, I found this rarity at a sale which had really cheap prices, but which in retrospect didn't seem entirely legit, taking place at a top floor storage facility and being advertised with a paper note taped to the outside wall. Anyway, I was there and saw that green box with that really ugly artwork in front. Another customer came over and began going on about how great the game was with eagerness normally found in those who wish to talk to you about Jesus. I bought the game. This was a trippy new age puzzler with grossly exaggerated "subliminal messages". Basically, the soundtrack sometimes broadcasts positive messages, and with each .wav song running under 10 seconds before repeating, those subliminal messages get delivered with the subtlety of a jackhammer. The gameplay was actually pretty good, with a surprising amount of depth. Still, the true strength of the game was how committed it was to its new age aesthetics, with the music, blatant positive messages, trippy colors and playfield turned at weird angles, sometimes even upside down.
I found a clip on youtube which shows the games color cycling effects:
