What is the main difference between reflection maps and environment maps?
What is the main difference between reflection maps and environment maps?
- Reflection maps are applied to one 3D surface at a time, while environment maps are projected on all objects with reflective surface characteristics in the scene. (correct)
- Reflection maps are monochromatic, while environment maps can have multiple colors.
- Reflection maps determine the brightness values of an object, while environment maps determine the shininess of an object.
- Reflection maps alter the orientation of surface normals, while environment maps affect the surface itself.
How does bump mapping simulate roughness on a smooth surface?
How does bump mapping simulate roughness on a smooth surface?
- By adjusting the brightness values of the surface to simulate roughness.
- By changing the color values of the surface without affecting the orientation of the surface normals.
- By physically modifying the surface to create roughness.
- By altering the orientation of the surface normals without affecting the surface itself. (correct)
What do the darkest and lightest values in a bump map represent?
What do the darkest and lightest values in a bump map represent?
- The darkest values represent the rough areas, and the lightest values represent the smooth areas in the simulated texture.
- The darkest values represent the smooth areas, and the lightest values represent the rough areas in the simulated texture.
- The darkest values represent the valleys, and the lightest values simulate the peaks in the simulated texture. (correct)
- The darkest values represent the peaks, and the lightest values simulate the valleys in the simulated texture.
