> ## Name

> PointDistanceAttenuation - 3D API point distance attenuation

> ## Usage

> PointDistanceAttenuation = float3(x, y, z)

> ## Valid Enumerants

> x, y, z: floating point values

> ## Description

> Specify the coefficients used to scale the computed point size. See the GL_POINT_DISTANCE_ATTENUATION description on the OpenGL glPointParameter manual page for details.

> The standard reset callback sets the PointDistanceAttenuation state to float3(1, 0, 0).
