AlembicCurvesReader (object)

The AlembicCurvesReader specializes the AlembicObjectReader interface for reading AlembicICurves data. It can be created using the AlembicArchiveReader.getCurves method.

AlembicCurvesReader ( in AlembicCurvesReader other )

copy constructor

---

AlembicCurvesReader ()

default constructor

---

Boolean AlembicCurvesReader.areSelfBoundsConstant? ()

Returns true if the bounds of this object, excluding the children, are constant

---

AlembicCurvesReader AlembicCurvesReader.clone? ()

clone method

---

SInt32 AlembicCurvesReader.getNumSamples? ()

returns the number of samples of this reader

---

String AlembicCurvesReader.getPath? ()

returns the full path of the wrapped AlembicICurves

---

AlembicICurvesSample AlembicCurvesReader.getSampleA? ()

returns the first sample used by this reader

---

AlembicICurvesSample AlembicCurvesReader.getSampleB? ()

returns the second sample used by this reader

---

AlembicICurvesSchema AlembicCurvesReader.getSchema? ()

returns the schema of this reader

---

Box3 AlembicCurvesReader.getSelfBounds! ( in Float64 time, io Boolean isConstant )

returns the bounding box

---

AlembicTimeSampling AlembicCurvesReader.getTimeSampling? ()

returns the timesampling of this reader

---

AlembicCurvesReader.readSample! ( in Float64 time, io Curves geom )

Reads a geometry sample at a given time

---

AlembicCurvesReader.readSample! ( in Float64 time, io Lines lines )

reads a sample at a given time. this will properly interpolate between samples. the result is stored in the provided Lines geometry.

---

AlembicCurvesReader.reset! ()

clears all pointers and releases all alembic containers

---

Boolean AlembicCurvesReader.valid? ()

returns true if this reader wraps a valid AlembicICurves
