Shadow bias moves the shadow toward or away from the shadow-casting object (or objects). In the following list, which option matches this description?

Shadow bias moves the shadow toward or away from the shadow-casting object (or objects). In the following list, which option matches this description?

• A. Size
• B. Shadow bias
• C. Sample range
• D. Density

Answer: (B)

Shadow bias is the setting that shifts the shadow relative to the object that casts it. In rendering, a small depth offset is added when comparing the light’s shadow map to the scene, which prevents self-shadow artifacts. By adjusting this offset, the shadow can be made to sit closer to the object or to appear slightly separated, effectively moving the shadow toward or away from the casting object. This directly matches the description of moving the shadow relative to the shadow-casting object. The other options change different aspects of how a shadow looks: size controls the softness of the shadow edges, sample range affects how many samples are used to compute the shadow (influencing quality and softness), and density alters how dark the shadow appears. None of these move the shadow’s position relative to the object, which is why shadow bias is the correct choice.
