Do Ray-Traced shadows support transparencies?

Do Ray-Traced shadows support transparencies?

• A. Yes, Ray-Traced shadows can include transparencies.
• B. No, Ray-Traced shadows do not support transparencies.
• C. Transparency is independent of Ray-Traced shadows.
• D. Transparencies are only supported in shadow maps.

Answer: (D)

Transparency in shadows depends on the shadow method you use. Ray-Traced shadows calculate illumination by tracing light rays and see if they are blocked by geometry; this approach typically treats surfaces as fully opaque for the purpose of the shadow, so it doesn’t capture partial light passing through translucent materials. Shadow maps, by contrast, are texture-based and can carry a material’s transparency information, allowing shadows to appear lighter or partially透 through where the object is translucent. Because of this, transparencies are supported in shadow maps, not in ray-Traced shadows. For scenes with transparent objects casting shadows, you’d use the shadow map option to achieve the expected transparency effect.
