Detailed Description

ParticlesSprite primitive.

Member Function Documentation

void ParticlesSprite::copy ( const ParticlesSprite *  b )

protected

Destructive copy.

References DD::Image::Primitive::copy().

Primitive * ParticlesSprite::duplicate ( ) const

virtual

Copy this Particles into a new one, and return a pointer to it. Vertex data is duplicated, point indices are unchanged.

Implements DD::Image::Primitive.

bool ParticlesSprite::tessellateSprite	(	unsigned int	spriteIndex,
		Scene *	scene,
		PrimitiveContext *	ptx,
		PrimitiveContext *	nptx,
		SpriteGenerator *	spriteGenerator,
		MBSceneSpriteGenerator *	mbSceneGenerator,
		ParticleSearchInfo &	searchInfo
	)		const

Get the tessellation for an individual sprite, by index. This will return true if the sprite is visible, false if not.

Parameters

nptx	Primitive context
spriteGenerator	Primitive context with local transforms removed, to use for adding sprites into the scene

void ParticlesSprite::tessellate ( Scene *  scene, PrimitiveContext *  ptx  ) const

virtual

Push a single rParticles primitive into the rendering stream.
