Detailed Description

A volume source from a 16 Bit float 3D grid capable of loading volume serializations.

Constructor & Destructor Documentation

◆ HalfFloatGridSource()

Ogre::Volume::HalfFloatGridSource::HalfFloatGridSource	(	const String &	serializedVolumeFile,
		const bool	trilinearValue = `true`,
		const bool	trilinearGradient = `false`,
		const bool	sobelGradient = `false`
	)

explicit

Constructur.

Parameters

serializedVolumeFile	Which volume serialization to get the data from.
trilinearValue	Whether to use trilinear filtering (true) or nearest neighbour (false) for the value.
trilinearGradient	Whether to use trilinear filtering (true) or nearest neighbour (false) for the gradient.
sobelGradient	Whether to add a bit of blur to the gradient like in a sobel filter.

◆ ~HalfFloatGridSource()

Ogre::Volume::HalfFloatGridSource::~HalfFloatGridSource ( void )

Destructor.

Member Function Documentation

◆ setMaxClampedAbsoluteDensity()

void Ogre::Volume::HalfFloatGridSource::setMaxClampedAbsoluteDensity ( Real maxClampedAbsoluteDensity )

Sets the maximum absolute density value to be written into the data when combining, influencing the compression rate on serialization.

Set it to 0.0 to deactivate.

Parameters

maxClampedAbsoluteDensity The maximum absolute density value.

◆ getMaxClampedAbsoluteDensity()

Real Ogre::Volume::HalfFloatGridSource::getMaxClampedAbsoluteDensity ( void ) const

Gets the maximum absolute density value to be written into the data when combining, influencing the compression rate on serialization.

Returns: The maximum absolute density value, 0.0 when deactivated.
