This simple example demonstrates the export of animation to a vertex cache using cortex. It can be used to generate vertex caches which can be used with the ExamplesProceduralsAnimatedMesh. It shows how to use the FileSequence and AttributeCache classes as well as how to convert maya objects to cortex objects.
import os
import maya.cmds
import IECore
import IECoreMaya
def writeVertexCaches( meshes, destinationFileSequence ) :
destinationDirectory = os.path.dirname( str( destinationFileSequence ) )
if not os.path.exists( destinationDirectory ) :
os.makedirs( destinationDirectory )
for frameNumber in destinationFileSequence.frameList.asList() :
maya.cmds.currentTime( frameNumber )
attributeCache = IECore.AttributeCache( destinationFileSequence.fileNameForFrame( frameNumber * 250 ), IECore.IndexedIOOpenMode.Write )
for mesh in meshes :
converter = IECoreMaya.FromMayaShapeConverter.create( mesh )
converter["space"].setValue( "World" )
points = converter.points()
bound = IECore.PointBoundsOp()( points=points )
attributeCache.write( mesh, "vertCache.P", points )
attributeCache.write( mesh, "vertCache.boundingBox", bound )
allMeshes = maya.cmds.ls( selection=True, noIntermediate=True, dag=True, type="mesh" )
writeVertexCaches( allMeshes, IECore.FileSequence( "/tmp/myCaches/cache.######.fio", IECore.FrameRange( 1, 50 ) ) )
