Detailed Description

Class containing all parts of a system for a single type of particle.

This class encompasses all the necessary parts to create a particle system which emits a single type of particle. In this particle system each particle changes over its lifespan according to a Gaussian interpolation. The changes could be transitioning from one size to another, one color to another or one alpha value to another.

Constructor & Destructor Documentation

XYZAxis::XYZAxis	(	float	length = 25.0f,
		const osg::Vec4 &	colorX = osg::Vec4f(1.0f, 0.0f, 0.0f, 1.0f),
		const osg::Vec4 &	colorY = osg::Vec4f(0.0f, 1.0f, 0.0f, 1.0f),
		const osg::Vec4 &	colorZ = osg::Vec4f(0.0f, 0.0f, 1.0f, 1.0f)
	)

Initialize CTOR The entire Axis is created at construction time.

Parameters

[in]	length	is the length of each axis.
[in]	colorX	is the color for the X axis (default red).
[in]	colorY	is the color for the Y axis (default green).
[in]	colorZ	is the color for the Z axis (default blue).

virtual

DTOR.

Member Function Documentation

osg::Node* XYZAxis::createAxis ( const osg::Vec4 &  color, unsigned int  numReps, const osg::Vec3 &  tick, const osg::Vec3 &  endPoint, const osg::Vec3 &  startPoint = osg::Vec3f(0.0f, 0.0f, 0.0f)  ) const

protected

A helper function to create one axis.

Parameters

[in]	color	is the color for the axis.
[in]	numReps	is the number of ticks in the axis.
[in]	tick	is the direction of the (orthogonal) tick.
[in]	endPoint	is the ending point of the axis.
[in]	startPoint	is the starting point of the axis.

Returns

A node containing the axis.

osg::Geometry* XYZAxis::createLine ( const osg::Vec4 &  color, const osg::Vec3 &  startPoint, const osg::Vec3 &  endPoint  ) const

protected

A helper function to create one line.

Parameters

[in]	color	is the color for the axis.
[in]	startPoint	is the starting point of the axis.
[in]	endPoint	is the ending point of the axis.

Returns

Geometry for the single line.
