Function Documentation

isNearEnough()

bool Vkm::Engine::Culling::isNearEnough ( const Math::AABB & bounds, const VisibilityContext & context )

inline

Distance culling: whether the AABB's centre is within maxDistance of the camera.

Parameters

bounds	World-space AABB.
context	Supplies cameraPosition and maxDistance (0 or below disables).

Returns

Whether the box survives.

isLargeEnough()

bool Vkm::Engine::Culling::isLargeEnough ( const Math::AABB & bounds, const VisibilityContext & context )

inline

Screen-size culling: whether the AABB's bounding sphere projects to minPixels or more.

The test does not apply behind the camera, under an orthographic view, with a zero viewport, or with minPixels at 0 or below.

Parameters

bounds	World-space AABB.
context	Supplies the view and screenSizeThresholdSq.

Returns

Whether the box survives.
