Kann das noch getopt werden? Wohl kaum. Aber das muss ich dann doch noch dran schrauben.

#totetmatt hat auf #Demozoo einfach mal alle #GLSL Files der #ShaderShowdown Runden 1-3 und vom Finale zusammen gestellt.

Also wenn das nicht mal n feiner Einflieger & DeepDve in das Thema ist:

WIP #maxmsp #jitter #glsl #fractal
Updating my old fractal raymarcher project. It has 11 transforms, each with variable execution order, variable start-end iteration and in the end the distance estimator has five modes... this way, a huge range of hybrid fractals are possible.
It contains lot of code from IQ and Fragmentarium shaders.

Hm, not happy with SPIR-V to ISA on my RDNA3 that is reordering loads from shared memory in some ways that it is actually slightly less efficient...

Is there a way to instruct the ISA compiler via GLSL to not reorder loads from shared mem? (Not workgroup/subgroup barriers but simple no-reordering) I haven't yet tried if volatile could do the trick 🤔

Anyone has some thoughts?

@bnut BAH! The sticky edges were due entirely to a bug in my projection code. The box size is just slightly less than 1 so that it fits in my collision detection grid and when projecting z, I failed also to project x and y. Now they no longer stick which leaves the cube edges somewhat less visible.

Here's a changing projection shape.
