Environment map renderer attributes.

Member Data Documentation

MipLevel

float Diligent::EnvMapRenderer::RenderAttribs::MipLevel = 0

Mip level of the environment map to use. Fractional levels blend adjacent mips. For atlas regions, the caller must limit this value to the region's valid mip range.

SphereMapRow0IsNegativeY

bool Diligent::EnvMapRenderer::RenderAttribs::SphereMapRow0IsNegativeY = false

Whether row 0 of a sphere map represents the negative Y direction. Ignored for cube maps.

SphereMapSlice

float Diligent::EnvMapRenderer::RenderAttribs::SphereMapSlice = 0

Array slice containing a sphere map. Ignored for cube and Texture2D source views.

SphereMapUVScaleBias

float4 Diligent::EnvMapRenderer::RenderAttribs::SphereMapUVScaleBias = {1, 1, 0, 0}

UV scale and bias used to address a sphere map in its backing texture. The identity transform samples the full image.

Yaw

float Diligent::EnvMapRenderer::RenderAttribs::Yaw = 0

Horizontal orientation of the environment, in radians. Rotation is around the positive Y axis; positive angles rotate +X toward -Z.
