I've started working with OpenGL and writing shaders. My app checks for errors after loading and compiling shader programs, and if there is a problem it prints out the info log. This is great for catching errors (and I'm a newbie so I'm making a lot), but what I'd really like is to catch these errors at build time. If I had a lint tool ...
I know that Floyd–Steinberg dithering algorithm can't be implemented with pixel shader, because that algorithm is strictly sequential. But maybe there exist some higly parallel dithering algorithm which by it's visual output is similar to Floyd-Steinberg algorithm ? So the question is - What are dithering algorithms which are suitable t...
I am just messing around with some geometry shaders taking a list of GL_POINTS and outputting a box with triangle strips. i have it basically working but when i zoom in/out or pan around the triangle strips go all over the place and do not maintain their posistion in the world but are still correctly drawing the box. for example if i g...
