Gaming applications like Minecraft take full advantage of it. Web4 de ago. de 2024 · Shadow Masks The basic idea is that before rendering each light, you use the shadow geometry to draw a mask that blocks the light from drawing where it’s not supposed to go. The easiest way to do this in most environments is to draw the shadow mask into the lightmap’s alpha channel.

WebBy generating an orthographic projection for each cascade separately we can now render each cascade into different shadow map. During the light phase we will calculate the shadow factor by selecting a shadow map based on the distance from the viewer.
