Interface: MaterialBump

Controls the surface relief and depth effects of a material.

Bump mapping creates the visual illusion of surface detail without adding geometric complexity. This interface defines how textures create the appearance of raised or recessed surface features through lighting effects.

Business value:

  • Adds perceived texture and detail to surfaces without performance impact
  • Essential for realistic leather, fabric, stone, and other textured materials
  • Creates depth perception that enhances product realism
  • Significantly improves visual quality with minimal performance cost

Properties​

isActive​

isActive: boolean

When true, applies the bump mapping effect to this material.

level​

level: string | number

Strength of the bump effect. Higher values create more pronounced surface relief.

parallaxScaleBias​

parallaxScaleBias: string

Controls parallax mapping intensity for enhanced depth effect.

texture​

texture: Partial<MaterialTexture>

The texture map that defines where bumps and indentations appear.

useParallax​

useParallax: boolean

When true, enables basic parallax mapping for enhanced depth.

useParallaxOcclusion​

useParallaxOcclusion: boolean

When true, enables advanced parallax occlusion mapping for realistic depth.
