WebNow, I'd like to have shadow mapped point lights as well. The things is, though, I'd like them to be as fast as possible. I'm not that interested in the quality - I can get away with really small shadow maps (256x256 or even 128x128), and I don't need soft shadows …

Web13 de mai. de 2024 · For spot lights using the cone angle as your FOV sounds good. For point lights it depends on where you want it to cast shadows. Technically a point light can cast a shadow all around. This is impossible with a single shadow map. You would need multiple shadow maps, ideally a shadow cube. WebIf we use a 8K by 8K shadow map atlas and the minimal resolution of each shadowmap is be 64 by 64, then we can fit 16 384 unique low resolution shadowmaps into the atlas, which is enough for around 2730 point lights. So in practise you can store shadows for dozens or low hundreds of point lights at various resolutions.
WebThe big/important lights (LOD!), where you are going to notice the shadowing more, could use shadow maps. Again, not that much into this stuff and don't know too much about graphics. (Also, you'll probably already know about it, but (tiled) deffered rendering is great for huge ammounts of light sources) 2 level 2 -manabreak Op · 7y Web30 de jun. de 2024 · To render the shadows of a spot light we need to know its visible light index, slope scale bias, and normal bias.
