Detailed Description

Class that constructs mesh information of a given mesh name

Remarks

Member Enumeration Documentation

enum ParticleUniverse::MeshInfo::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.

Constructor & Destructor Documentation

ParticleUniverse::MeshInfo::MeshInfo ( const String &  meshName,

const Quaternion &  orientation = Quaternion::IDENTITY,
const Vector3 &  scale = Vector3::ZERO 
)

Constructor

Destructor

Member Function Documentation

Real ParticleUniverse::MeshInfo::getGaussianRandom ( Real  high,
Real  cutoff = 4 
)

Generate a random number. The ´high´ argument determines that numbers are returned between [0..high]

void ParticleUniverse::MeshInfo::getMeshInformation ( Ogre::MeshPtr  mesh,
const Vector3 &  position = Vector3::ZERO,
const Quaternion &  orient = Quaternion::IDENTITY,
const Vector3 &  scale = Vector3::UNIT_SCALE 
)

Retrieve vertex info

const Triangle::PositionAndNormal ParticleUniverse::MeshInfo::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.

const size_t ParticleUniverse::MeshInfo::getRandomTriangleIndex ( void  )

Get a random triangle (index) from the mesh.

const Triangle& ParticleUniverse::MeshInfo::getTriangle ( size_t  triangleIndex)

Get a triangle based on the index.
