virtual void makVrv::DtDropParticle::setParent ( DtDropParticle * drop )

virtual

If this drop was left behind from wetting from another drop, keep track of the parent drop.

virtual DtDropParticle* makVrv::DtDropParticle::parent ( ) const

virtual

virtual float makVrv::DtDropParticle::mass ( ) const

virtual

set/get the mass

virtual void makVrv::DtDropParticle::setMass ( float m )

virtual

virtual const osg::Vec2f& makVrv::DtDropParticle::velocity ( ) const

virtual

get the velocity

virtual void makVrv::DtDropParticle::affectedCells ( std::vector< osg::Vec2s > & cells ) const

virtual

Gets all screen grid cells covered by this drop.

virtual void makVrv::DtDropParticle::computeRadius ( double waterOnScreenSize )

virtual

compute radius

virtual void makVrv::DtDropParticle::update	(	double	time,
		double	elapsedTime,
		DtGridCell	grid[][GRID_DIMENSION],
		bool &	destroyFlag
	)

pure virtual

Update the particle.

Implemented in makVrv::DtSplashParticle, and makVrv::DtRaindropParticle.

virtual void makVrv::DtDropParticle::gridPosition	(	int &	gx,
		int &	gy
	)		const

virtual

get the grid position

virtual void makVrv::DtDropParticle::renderToNormalMap ( osg::Image * image )

virtual

Draw the droplet into the normal map for postprocessing.

This is where most of the time is spent. If further optimization is needed, we could only redraw drops that have moved instead of drawing every drop every frame. Or, we could render the drops using hardware and render to texture. Note this is a lot faster in release builds.

Reimplemented in makVrv::DtSplashParticle.

virtual bool makVrv::DtDropParticle::mergeable ( ) const

virtual

can this be merged with another particle?

virtual unsigned int makVrv::DtDropParticle::precomputedDropletTexel	(	float	x,
		float	y
	)

virtual

static void makVrv::DtDropParticle::precomputeDroplet ( )

static

Precompute a normal map for a drop.
