Writting to the envelope array is usually pretty fast for me... what's taking time (in my case) is doing all the normalization of values...
This is how I read my weights : def getWeights(envelopeOp): weightsTuple = envelopeOp.Weights.Array return [weightsTuple[j][i] for i in range(len(weightsTuple[0])) for j in range(len(weightsTuple))] This is an example of how I set the weights (average weights) : def averageWeights(envelopeOp, points=None): ''' \remarks set the weights of given points to the average weights of given points \param envelopeOp Envelope Operator - the envelope operator. \param points List of Integer - Index of vertices to average. ''' deformerCount = envelopeOp.Deformers.Count weightsTuple = envelopeOp.Weights.Array weights = getWeights(envelopeOp) if points is None: points = range(mesh.ActivePrimitive.Geometry.Points.Count) a = [0] * deformerCount for pointIndex in points: for def_index in range(deformerCount): a[def_index] += weightsTuple[def_index][pointIndex] for pointIndex in points: for def_index in range(deformerCount): weights[pointIndex*deformerCount + def_index] = a[def_index]/len(points) envelopeOp.Weights.Array = weights On 30 May 2013 12:58, Eric Thivierge <ethivie...@hybride.com> wrote: > Anyone know if there is a way to speed up reading and writing speeds to > the Weights Array for envelopes?
