Member Data Documentation

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.
