Detailed Description

Class that constructs mesh information of a given mesh name.

Remarks

Member Enumeration Documentation

enum MeshSurfaceDistribution

Defining several methods to emit particles on the mesh surface.

Remarks

Sometimes the difference is not always visible, for example if the mesh contains triangles with more or less the same size. Only in case a mesh contains both small and large triangles the difference between the various distribution methods is more obvious.

Member Function Documentation

float getGaussianRandom	(	float	high,
		float	cutoff = 4
	)

Generate a random number.

The ´high?argument determines that numbers are returned between [0..high]

var getGaussianRandom	(	var	high,
		var	cutoff = 4
	)

Generate a random number.

The ´high?argument determines that numbers are returned between [0..high]

local getGaussianRandom	(	local	high,
		local	cutoff = 4
	)

Generate a random number.

The ´high?argument determines that numbers are returned between [0..high]

const PUTriangle::PositionAndNormal getRandomPositionAndNormal

(

const size_t

triangleIndex

)

Returns both a random point on a given triangle and its normal vector.

How the random point and the normal are determined depends on the distribution type.

var getRandomPositionAndNormal

(

var

triangleIndex

)

Returns both a random point on a given triangle and its normal vector.

How the random point and the normal are determined depends on the distribution type.

local getRandomPositionAndNormal

(

local

triangleIndex

)

Returns both a random point on a given triangle and its normal vector.

How the random point and the normal are determined depends on the distribution type.

const size_t getRandomTriangleIndex

(

void

)

Get a random triangle (index) from the mesh.

var getRandomTriangleIndex

(

)

Get a random triangle (index) from the mesh.

local getRandomTriangleIndex

(

)

Get a random triangle (index) from the mesh.

const PUTriangle& getTriangle

(

size_t

triangleIndex

)

Retrieve vertex info.

Get a triangle based on the index.

var getTriangle

(

var

triangleIndex

)

Retrieve vertex info.

Get a triangle based on the index.

local getTriangle

(

local

triangleIndex

)

Retrieve vertex info.

Get a triangle based on the index.

size_t getTriangleCount ( ) const
