plReflectionProbeUpdater Class Reference

Renders reflection probes and stores filtered mipmap chains into an atlas texture as well as computing sky irradiance Rendering sky irradiance is optional and only done if m_iIrradianceOutputIndex != -1. More...

GetFreeUpdateSlots()

plUInt32 plReflectionProbeUpdater::GetFreeUpdateSlots

(

plDynamicArray< plReflectionProbeRef > &

out_updatesFinished

)

Returns how many new probes can be started this frame.

Parameters

out_updatesFinished

Contains the probes that finished last frame.

Returns

The number of new probes can be started this frame.

StartDynamicUpdate()

plResult plReflectionProbeUpdater::StartDynamicUpdate	(	const plReflectionProbeRef &	probe,
		const plReflectionProbeDesc &	desc,
		const plTransform &	globalTransform,
		const TargetSlot &	target )

Starts rendering a new reflection probe.

Parameters

probe	The world and probe index to be rendered. Used as an identifier.
desc	Probe render settings.
globalTransform	World position to be rendered.
target	Where the probe should be rendered into.

Returns

Returns PL_FAILURE if no more free slots are available.

StartFilterUpdate()

plResult plReflectionProbeUpdater::StartFilterUpdate	(	const plReflectionProbeRef &	probe,
		const plReflectionProbeDesc &	desc,
		plTextureCubeResourceHandle	hSourceTexture,
		const TargetSlot &	target )

Starts filtering an existing cube map into a new reflection probe.

Parameters

probe	The world and probe index to be rendered. Used as an identifier.
desc	Probe render settings.
sourceTexture	Cube map that should be filtered into a reflection probe.
target	Where the probe should be rendered into.

Returns

Returns PL_FAILURE if no more free slots are available.
