Programming / New CRT-style shader & questions about provided uniforms
« on: October 19, 2020, 03:43:19 am »
Hi There!
I've recently adapted Timothy Lottes' RetroArch CRT-style shader (example down below, picture taken from the libretro docs) for OpenXcom, and I'm pretty happy with it so far. One small thing I'm having trouble with: What's the difference between rubyInputSize and rubyTextureSize? As far as I can tell, using either as the input resolution results in exactly the same output. Is there a reason I should use one and not the other?
Second question: I've ripped out the screen warp effect of Lottes' shader, emulating the curvature of CRTs, just because I personally don't like the looks of it. How do you feel about it and should I include a second version of the shader with warp?
Thank you so much!
