Yes, Löve has a way to do
shaders. It uses a form of GLSL 120 but varies a bit. Specifically some variable names and has a function for each type of shader(fragment and vertex).
I however am having trouble understanding it... somewhat. More like I'm trying to beat a dead horse to tell me how to by pass Löve's difference in normals and "per-vertex" and the like. I was trying to do something very similar to what's in that picture. I believe it was per-fragment lighting.
There's a good
tutorial series that got me starting to learn about shaders. Sadly A: He never really finished it. and B: It doesn't teach you how to by pass Löve differences in GLSL.
You can find the shader variables
here. But since that never really helped me learn their equivalence to GLSL variables I used
this.
I pretty much have no real luck with it, and getting people to help you seems to be less successful than asking for help on a subject without someone saying "there's a library for that".
As far as what you're saying is it possible to do it on the GPU? That's what these shaders do.
Sorry I can't be more helpful but it seems shaders are a difficult thing to get into. At least for me and my ability to understand what slime says [urlhttps://love2d.org/forums/viewtopic.php?f=4&t=78250]here[/url]. But yeah, Löve shaders, nice little forum post of everyone showing off their skill
here that you've probably already seen.
