Summary

0001472: PCAShapeSignedDistanceFunction not thread safe

Description

PCAShapedSignedDistanceFunction changes the ivar m_Selectors during the call to Evaluate(). If two threads call Evaluate() they m_Selectors could be corrupted or set incorrectly for one of the threads.

m_Selectors is used to cache whether an iterpolating function or extrapolating function needs to be used.

Notes
(0009081) Luis Ibanez (manager) 2007-09-18 11:43	To be addressed during WA10. Two potential options: a) in the filter that use this function, instantiate one per thread b) fix the functions to make them thread safe.
