Does anyone know of an APL compiler or transpiler that can generated Vulkan or OpenGL shader scripts? (Free/libre would be most appreciated.) I think Aaron Hsu might have engineered something like this at some point, but I can't find anything about it at all right now, probably thanks to our amazing new "AI-enhanced" search engines.
@codrusofathens I did narrow my query but without using quotes. My query was something like "apl programming GPU OpenGL shader GLSL" or something like that.
I just tried again with "apl programming compiler target shader GLSL aaron hsu" and I got the APL wiki page for Aaron Hsu which mentions his work on a GPU-hosted APL compiler and links to the Co-dfns GitHub page, as well as his Ph.D thesis. It looks like I almost had the winning query before I posted this question. Of course, you always have perfect vision in hindsight.
@ramin_hal9001@codrusofathens iirc, Hsu's APL GPU work is more like Harlan, in that it compiles to compute kernels rather than GLSL vertex + fragment shaders. So it could be good for implementing a path tracing renderer, which could have its own PBR shader language, but in terms of getting straight to pixel pushing, not particularly useful.
But it should be a match made in heaven, APL is a much more natural environment for linear algebra than GLSL's C-style syntax.
