<redeyedman> does cycles implemented on opengl api as well as eevee?
<Yaniel> no
<Yaniel> cycles works completely differently from eevee
<Yaniel> eevee is a game-like renderer built on opengl, cycles is a path tracer built on opencl and cuda
<redeyedman> Yaniel, my friend says I can't get good shdows and reflections with eeevee because it use opengl, is it true?
<Yaniel> shadows and reflections are more limited in eevee yes, because of the way opengl works
<Yaniel> which is good for getting complex shapes on screen really fast
<Yaniel> but bad for simulating the bouncing of photons
<stiv> the usual game engine vs renderer stuff
<Yaniel> but that does not mean you can't get good-looking shadows and reflections
<Yaniel> they just require a bit more care, and you need to take them into account when designing your scene
<Yaniel> i.e. stuff you'd have to account for if you were designing a level for a game
basically what eevee does is render the scene from the pov of each light that casts shadows and then when rendering your camera it uses the depth as seen from each light to determine if the light hits each point seen by the camera
