What is the primary role of a 3D space in Fusion when creating depth cues?

• A. To place 3D primitives, lights, and cameras within a scene for realistic depth.
• B. To render 2D images with no depth.
• C. To convert color spaces automatically.
• D. To speed up preview rendering.

Answer: (A)

Creating depth cues relies on establishing a true 3D workspace where objects exist with depth along the Z axis. By placing 3D primitives, lights, and a camera inside a scene, you define perspective: the camera provides a viewpoint, lights shape shading and shadows, and the 3D geometry gives spatial relationships so elements can occlude and parallax as the camera or objects move. This combination is what lets you simulate realistic depth in Fusion composites. Rendering 2D images with no depth won’t give you those cues, automatic color-space conversion isn’t about depth, and speeding up preview rendering doesn’t create depth either.
