Which term refers to data that controls the appearance of surfaces, including color and opacity?

• A. Material
• B. Texture
• C. Lighting
• D. Shader

Answer: (A)

In this context, the term for data that defines how a surface looks—including its color and how opaque it is—is the material. A material is the container of surface properties such as diffuse color, opacity, reflectivity, and other attributes that determine appearance. Textures are images that can drive or modulate those properties within a material, but they are not the overall data that controls appearance on their own. Lighting affects how the material is perceived, and a shader is the programming that actually computes the shading within the material, but the primary data describing the surface’s look is the material itself.
