Instance Property

highDynamicRangeCompression

Two parameters that determine the brightness compression curve for colors in the texture image.

Declaration

var highDynamicRangeCompression: vector_float2 { get set }

Discussion

To render a sky texture, Model I/O first simulates the colors visible in the sky at different directions and then applies tone mapping to fit the resulting colors into the range of displayable values. In tone mapping, Model I/O ignores values below the x component of this vector, clamps color values at or above the y component to the maximum display brightness, and smoothly scales color values in between those points.
