This is done by taking the particle's current position and velocity, and extrapolation backwards in time.
NOTE: For an MFnParticleSystem of renderType kTube, use position0() and position1() instead.
void velocity | ( | MVectorArray & | array | ) | const |
To return velocity array for all particles.
[out] | array | The resulting velocity array |
void acceleration | ( | MVectorArray & | array | ) | const |
To return acceleration array for all particles.
[out] | array | The resulting acceleration array |
void position0 | ( | MVectorArray & | positions | ) | const |
Only for use with an MFnParticleSystem of renderType kTube.
Calculates particle start positions.
void position1 | ( | MVectorArray & | positions | ) | const |
Only for use with an MFnParticleSystem of renderType kTube.
Calculates particle end positions.
void radius | ( | MDoubleArray & | radii | ) | const |
Calculates particle radii.
NOTE: For an MFnParticleSystem of renderType kTube, use position0() and position1() instead.
void radius0 | ( | MDoubleArray & | radii | ) | const |
Only for use with an MFnParticleSystem of renderType kTube.
Calculates the particles' start radii.
void radius1 | ( | MDoubleArray & | radii | ) | const |

double surfaceShading | ( | ) | const |
Only for use with an MFnParticleSystem of renderType kCloud.
Returns the object surface shading value.
double threshold | ( | ) | const |
Only for use with an MFnParticleSystem of renderType kCloud or kBlobby.
Returns the object threshold.
bool betterIllum | ( | ) | const |
Only for use with an MFnParticleSystem of renderType kCloud.
Returns a boolean indicating whether or not thick cloud sampling is already enabled.
bool flatShaded | ( | ) | const |
To check if a particle shape of cloud type is flat shaded.
This is only for use with an MFnParticleSystem of renderType kCloud.
bool disableCloudAxis | ( | ) | const |
Only for use with an MFnParticleSystem of renderType kCloud.
Internal use for better illum.
NOTE: Internal use only. Do not call.
double tailSize | ( | ) | const |
Only for use with an MFnParticleSystem of renderType kTube.
Returns the length scale factor.
void particleIds | ( | MIntArray & | ids | ) | const |
Return an array of particle identifiers at the start of the time step.
The array of particle id's is correlated with the other per-particle arrays returned by this class, so ids[i] will be the id for the particle with position position[i], velocity[i], etc., as long as all these arrays were retrieved for the same time step.
The particle id is a constant identifier for an individual particle that does not change between time steps. The particle id can be used to follow the path of a single particle between frames. Only living particle identifiers are returned by this method.
[out] | ids | Array of particle identifiers. The contents of the array are overwritten with the current list of particle identifiers. |
void lifespan | ( | MDoubleArray & | lifespans | ) | const |
Populates the given array with the lifespan values of the particles in this system, if the particles have this attribute.
See hasLifespan().
void rgb | ( | MVectorArray & | colors | ) | const |
Populates the given array with the color values of the particles in this system, if the particles have this attribute.
See hasRgb().
For each particle, processes the internal representation into RGB color values, which are mapped to a vector.
void opacity | ( | MDoubleArray & | opacities | ) | const |
Populates the given array with the opacity values of the particles in this system, if the particles have this attribute.
See hasOpacity().
void mass | ( | MDoubleArray & | array | ) | const |
To return mass array for all particles.
[out] | array | The resulting mass array |
void emission | ( | MVectorArray & | emissions | ) | const |
Populates the given array with the incandescence values of the particles in this system, if the particles have this attribute.
See hasEmission().
bool hasLifespan | ( | ) | const |
Returns whether or not the particles in this system have a lifespan attribute.
See lifespan().

See rgb().
bool hasOpacity | ( | ) | const |
Returns whether or not the particles in this system have an opacity attribute.
See opacity().
bool hasEmission | ( | ) | const |
Returns whether or not the particles in this system have an emission attribute.
See emission().
