The NParticleReader class defines a class for reading IFF cache files (Maya nCaches) onto a PointsPrimitive.
|
overridevirtual |
Fills the passed vector with the names of all attributes in the file.
Implements IECore::ParticleReader.
const IntVectorData* IECore::NParticleReader::frameTimes | ( | ) |
returns IntVectorData of all frames contained in the nCache the frameIndex parameter should be set using an index into this IntVectorData
|
overridevirtual |
Returns the number of particles in the file. This returns the absolute total, rather than one affected by the percentage parameter.
Implements IECore::ParticleReader.
|
overridevirtual |
Reads the specified attribute, filtered by the percentage specified in parameters(). Returns 0 if the attribute doesn't exist. The type of Data is chosen automatically to best represent the particle data.
Implements IECore::ParticleReader.
