std::ostream & | operator<< (std::ostream &output, const Data< T, d > &v) |
The interface of the particle API (Partio) what type the primitive is, how many instances of the primitive there, name of the attribute and an index which speeds lookups of data
typedef Data<float,1> Partio::DataF |
typedef Data<int,1> Partio::DataI |
typedef Data<float,3> Partio::DataV |
typedef uint64_t Partio::ParticleIndex |
Opaque random access method to a single particle. No number is implied or guaranteed.
void Partio::beginCachedAccess | ( | ParticlesData * | particles | ) |
Begin accessing data in a cached file.
Indicates to Partio that data access from a cached particle set will start. The sent in particles pointer must be from a readCached() call, not from read() or create(). Attributes can be read before this call.
ParticlesDataMutable* Partio::create | ( | ) |
Provides an empty particle instance, freed with p->release()
ParticlesDataMutable* Partio::createInterleave | ( | ) |
void Partio::endCachedAccess | ( | ParticlesData * | particles | ) |
End accessing data in a cached file.
Indicates to Partio that data from a cached particle read will end. The sent in particles pointer must be from a readCached() call, not from read() or create(). This allows the particle API to free all data pages, if they are needed.
std::ostream& Partio::operator<< | ( | std::ostream & | output, |
const Data< T, d > & | v | ||
) |
void Partio::print | ( | const ParticlesData * | particles | ) |
Prints a subset of particle data in a textual form.
ParticlesDataMutable* Partio::read | ( | const char * | filename | ) |
Provides read/write access to a particle set stored in a file freed with p->release()
ParticlesData* Partio::readCached | ( | const char * | filename, |
const bool | sort | ||
) |
Cached (only one copy) read only way to read a particle file.
Loads a file read-only if not already in memory, otherwise returns already loaded item. Pointer is owned by Partio and must be releasedwith p->release(); (will not be deleted if others are also holding). If you want to do finding neighbors give true to sort
ParticlesInfo* Partio::readHeaders | ( | const char * | filename | ) |
Provides read access to a particle headers (number of particles and attribute information, much cheapeer
bool Partio::typeCheck | ( | const ParticleAttributeType & | type | ) |
References FLOAT, INDEXEDSTR, INT, and VECTOR.
std::string Partio::TypeName | ( | ParticleAttributeType | attrType | ) |
|
inline |
References FLOAT, INDEXEDSTR, INT, NONE, and VECTOR.
void Partio::write | ( | const char * | filename, |
const ParticlesData & | , | ||
const bool | forceCompressed = false |
||
) |
Provides access to a particle set stored in a file if filename ends with .gz or forceCompressed is true, the file is compressed.
