AlembicCurvesWriter (object)¶

The AlembicCurvesWriter specializes the AlembicObjectWriter interface for writing AlembicOCurves data. It can be created using the AlembicArchiveWriter.addCurves methods.

** Example: AlembicCurvesWriter

require AlembicWrapper;
require FileIO;

operator entry() {
  
  FilePath path = FilePath('${TEMP}/curves.abc').expandEnvVars();

  AlembicArchiveWriter archive(path.string());
  AlembicXformWriter xfo = archive.addXform('/xfo', Alembic_kConstantTimeSampling);
  AlembicCurvesWriter curves = archive.addCurves('/xfo/curves', Alembic_kConstantTimeSampling);

  xfo.writeSample(Mat44());

  Lines lines = Lines();
  lines.addPoints( 6 );

  lines.setPosition( 0, Vec3(1,0,0) );
  lines.setPosition( 1, Vec3(-1,0,0) );

  curves.writeSample(lines);

  archive.reset();

  report(path.exists());
  report('Alembic file created: '+path.string());

** Output:

true
