Real-time Soft Shadows with Shadow Accumulation

Figure 8: Using a standard shadow map results in hard shadows (left), add a penumbra map to get soft

This information is used in the rendering pass of the final image to determine whether a point lies in shadow by comparing its light source with the shadow map distance, which can

The three main sources of unnecessary shadow volume rendering are: large regions of empty space, shadow casters completely enclosed in other shadow volumes, and shadow generation

While in outdoor scenes the shadow regions can be projected on the ground around the object, in indoor environment, due to different light sources and reflection effects, the

The algorithm is decomposed into two steps: first, it computes the shadow map from the light and then, for each pixel of the V-buffer, if its corresponding point p is in the

Consequently, the larger the depth between the vir- tual objects and the real object, the larger the positional error between the shadow that is projected onto the real object’s

The use of a simple shadow map test as source function f x,y (n) for the history buffer shows the following property: If an eye fragment transformed into light space is exactly at

The depth buffer shadow method is used to judge whether a position is in shadow from a light source by storing the depth of the object as a color in a shadow texture using a
