struct · #include <rayrai/RenderDiagnostics.hpp>

One cascade of a DirectionalShadowCascadePlan. Distances are view distances in metres.

Public attributes

index

int index

Cascade index, 0 = nearest.

nearPlane

float nearPlane

Start of the cascade's view-distance slice.

farPlane

float farPlane

End of the cascade's view-distance slice.

splitDepth

float splitDepth

Split distance to the next cascade (equals farPlane).

texelWorldSize

float texelWorldSize

World-space size of one shadow-map texel, metres.

center

glm::vec3 center

World-space center of the cascade's projection.

lightSpaceMin

glm::vec3 lightSpaceMin

Light-view AABB minimum of the slice frustum corners.

lightSpaceMax

glm::vec3 lightSpaceMax

Light-view AABB maximum of the slice frustum corners.

lightSpaceHalfExtents

glm::vec3 lightSpaceHalfExtents

Half-size of that AABB.

lightSpaceMatrix

glm::mat4 lightSpaceMatrix

World-to-shadow-clip matrix (projection * view, texel-snapped).
