Parameters

posLS Position, in local space (relative to this probe)

Returns: Interpretation: <=0 means we're inside the inner range, or in its border. Range (0; 1) we're between inner and outer range. >=1 means we're outside the object.

◆ initWorkspace()

		IdString	workspaceDefOverride = `IdString()`,
		const CompositorChannelVec &	additionalChannels = `CompositorChannelVec()`,
		uint8	executionMask = `0xFF`
	)

Initializes the workspace so we can actually render to the cubemap.

You must call setTextureParams first.

Parameters

mipmapsExecutionMask

When ParallaxCorrectedCubemapAuto needs to use DPM via 2D Array (see ParallaxCorrectedCubemapAuto::setUseDpm2DArray), you will most likely NOT want to execute the mipmap pass in the workspace you provide, as the system will automatically generate mipmaps for you in the 2D Array instead. We will be using this value to skip that pass. We'll be calling:

compositorManager->addWorkspace( ..., executionMask = ~mipmapsExecutionMask);

But only when ParallaxCorrectedCubemapAuto::getUseDpm2DArray is true.

workspaceDefOverride Pass a null IdString() to use the default workspace definition passed to ParallaxCorrectedCubemap. This value allows you to override it with a different workspace definition.

◆ isInitialized()

bool Ogre::CubemapProbe::isInitialized ( ) const

◆ set()

void Ogre::CubemapProbe::set	(	const Vector3 &	cameraPos,
		const Aabb &	area,
		const Vector3 &	areaInnerRegion,
		const Matrix3 &	orientation,
		const Aabb &	probeShape
	)

Sets cubemap probe's parameters.

Parameters

cameraPos	Specify where the camera will be positioned.
area	When the camera enters this area, the probe is collected for blending.
areaInnerRegion	A value in range [0; 1]. It indicates a % of the OBB's size that will have smooth interpolation with other probes. When region = 1.0; stepping outside the OBB's results in a lighting "pop". The smaller the value, the smoother the transition, but at the cost of quality & precision while inside the OBB (as results get mixed up with other probes'). The value is per axis.
orientation	The orientation of the AABB that makes it an OBB. This orientation is applied to both probeShape AND area. Skewing and shearing is not tested. May or may not work.
probeShape	Note AABB is actually an OBB (Oriented Bounding Box). See orientation parameter. The OBB should closely match the shape of the environment around it. The better it fits, the more accurate the reflections.

◆ setPriority()

void Ogre::CubemapProbe::setPriority ( uint16 priority )

When two probes overlap, you may want one probe to have particularly more influence than the others.

Use this value to decrease/increase the weight when blending the probes.

Remarks: This value is only useful for Per-Pixel cubemaps

Parameters

priority A value in range [1; 65535] A higher value means the probe should have a stronger influence over the others.

◆ setStatic()

void Ogre::CubemapProbe::setStatic ( bool isStatic )

Set to False if it should be updated every frame.

True if only updated when dirty

Remarks: This call is not cheap.

◆ setTextureParams()

void Ogre::CubemapProbe::setTextureParams	(	uint32	width,
		uint32	height,
		bool	useManual = `false`,
		PixelFormatGpu	pf = `PFG_RGBA8_UNORM_SRGB`,
		bool	isStatic = `true`,
		SampleDescription	sampleDesc = `SampleDescription()`
	)

Remarks: When this CubemapProbe belongs to ParallaxCorrectedCubemapAuto, all parameters except isStatic are ignored! This call is still required.

Parameters

width
height
pf
isStatic	Set to False if it should be updated every frame. True if only updated when dirty
sampleDesc
useManual	Set to true if you plan on using thie probe for manually rendering, so we keep mipmaps at the probe level. User is responsible for supplying a workspace definition that will generate mipmaps though!

Member Data Documentation

◆ mDirty

bool Ogre::CubemapProbe::mDirty

True if we must re-render to update the texture's contents. False when we don't.

◆ mEnabled

bool Ogre::CubemapProbe::mEnabled

While disabled, this probe won't be updated (even if dirty) and won't be considered for blending (i.e.

won't be used at all).

◆ mMask

uint32 Ogre::CubemapProbe::mMask

Mask to group probes.

This probe will only be updated (even if dirty) and blended if mMask & system->mMask is non-zero. Useful for example for probes to be used during the day while other probes to be used during the night; thus you only want one group to be active at the same time. Or if you have per room probes, but during a panoramic shot where many rooms are in sight, and you want a more "global" probe. Defaults to 0xffffffff

◆ mNumIterations

uint16 Ogre::CubemapProbe::mNumIterations

Number of iterations.

The more iterations, the more light bounces and light reflections we can capture (i.e. mirror of mirrors), but it will take longer to rebuild the probe. Default value is 32. For non-static probes, you should set this value to 1 for performance.
