Member Function Documentation

void ParticlesSprite::copy

(

const ParticlesSprite *

b

)

[protected]

Destructive 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.
