Detailed Description

A program class for performing operations on particles using a sequence of operators.

To use a FluidProgram you have to create some Operator objects and add them to the program. All operators will be applied to each particle in the same order they've been added to the program.

void osgParticle::FluidProgram::setFluidToWater ( )
inline

Set the fluid parameters as for pure water (20C temperature).

◆ setFluidViscosity()

void osgParticle::FluidProgram::setFluidViscosity ( float  v)
inline

Set the viscosity of the fluid.

References osg::PI.

◆ setToGravity()

void osgParticle::FluidProgram::setToGravity ( float  scale = 1.0f)
inline

Set the acceleration vector to the gravity on earth (0, 0, -9.81).

The acceleration will be multiplied by the scale parameter.

◆ setWind()

void osgParticle::FluidProgram::setWind ( const osg::Vec3 wind)
inline

Set the wind vector.
