esp::gfx::PbrPrecomputedMapShader class
#include <esp/gfx/PbrPrecomputedMapShader.h>

A shader to output the irradiance map, applied in the IBL diffuse part, or the prefiltered environment map, applied in the IBL specular part, based on the user setting.

Enum documentation

enum esp::gfx::PbrPrecomputedMapShader::(anonymous): Magnum::UnsignedInt

Enumerators
ColorOutput	Color shader output. Generic output, present always. Expects three- or four-component floating-point or normalized buffer attachment.

enum class esp::gfx::PbrPrecomputedMapShader::Flag: Magnum::UnsignedShort

Flag.

Enumerators
IrradianceMap	This shader is set to compute the irradiance map
PrefilteredMap	This shader is set to compute the prefiltered environment map
