Struct IPLMaterial

The acoustic properties of a surface.

You can specify the acoustic material properties of each triangle, although typically many triangles will share a common material.

The acoustic material properties are specified for three frequency bands with center frequencies of 400 Hz, 2.5 KHz, and 15 KHz.

Below are the acoustic material properties for a few standard materials.

Fields

absorption: [IPLfloat32; 3]

Fraction of sound energy absorbed at low, middle, high frequencies. Between 0.0 and 1.0.

scattering: IPLfloat32

Fraction of sound energy scattered in a random direction on reflection. Between 0.0 (pure specular) and 1.0 (pure diffuse).

transmission: [IPLfloat32; 3]

Fraction of sound energy transmitted through at low, middle, high frequencies. Between 0.0 and 1.0. Only used for direct occlusion calculations.
