Hello Bernard,
When you read the point position array of a piece of geometry, XSI will
evaluate the graph of operators and if the syflex ops are dirty (they should
be if you ask for a different frame), the cache will be generated. We used
that on Happy Feet to compute syflex caches on the render farm, it's a very
time-saving thing to do!
In a perfect world, you should be able to call the Geometry(frameNumber),
but we had some problems on the farm with this method, using a SetValue of
the current frame makes it work everywhere.
Here's a snippet:
syOps = XSIFactory.CreateActiveXObject('XSI.Collection')
syOps.Items = '*.*.polymsh.syCloth'
syObjs = [op.Parent.Parent for op in syOps]
playCtl = Application.Dictionary.GetObject('PlayControl')
for frame in range( playCtl.In.Value, playCtl.Out.Value):
Application.SetValue('PlayControl.Current', frame)
for syObj in syObjs:
Application.LogMessage('Frame: %d: Updating %s'%(frame,syObj))
points =
syObj.ActivePrimitive.Geometry.Points.PositionArray
Cheers,
Aloys
