Screen space shadow mapping
Webb30 aug. 2016 · The screen-space shadow map is a screen-space effect and doesn't concern us. To support all relevant passes, we have to add a pass to our shader, with its light mode set to ShadowCaster . Because we are only interested in the depth values, it will be a lot simpler than our other passes. WebbWhereas, setting the Contact Shadow's length to a value of 0.5 means that the ray traverses only half of the screen. Note that the number of samples taken in the scene depth buffer remain constant, which means that you'll see more noise (artifacts) as you increase the Contact Shadow's length.

Webb16 okt. 2015 · Shadow maps are easy to compute in real-time and its many variants produce high quality shadows at interactive rates. With simple filtering techniques or by incorporating multiple shadow maps per area light source, soft-shadows can also be produced at interactive rates depending on the scene complexity.

For directional lights, the whole screen can be illuminated. For Spot Lights and Point Lights, the area is the onscreen projection of the shape of the light’s extent: a sphere for point lights, or a cone for Spot Lights. Webb30 sep. 2024 · Shadow mapping is very simple on paper. The technique is based on the idea that if an area is exposed to a light source, it can see the light source.
