hi Luis,
you can use (pdata-size) to get the size of the pdata arrays. using (pdata-ref) you can get the position of a given vertex index. using (pdata-index-map!) you can get the index and the position of all the vertices that you can change in a loop.How can I know the extact number and position of a vert, in order to deform them using pdata-set!?
best, gabor
