Public Attributes
glm::vec3	cameraPosition
	World space.
float	minPixels
	Pixels below which screen-size culling rejects; <= 0 disables.
float	maxDistance
	Distance beyond which distance culling rejects; <= 0 disables.
float	screenSizeThresholdSq
float	lodDistanceScale = 1.0f
	LOD::REFERENCE_P11 over the view's projection[1][1]: what a distance counts for in LOD selection.
bool	perspective = true
	Whether the view divides by depth.

Detailed Description

Per-frame data the culls read.

Member Data Documentation

screenSizeThresholdSq

float Vkm::Engine::VisibilityContext::screenSizeThresholdSq

(minPixels / (projScaleY * viewportHeight))^2.

perspective

bool Vkm::Engine::VisibilityContext::perspective = true

Whether the view divides by depth.

False turns screen-size culling off: orthographic size does not fall with distance.
