FrankFirsching Posted November 18, 2004 Share Posted November 18, 2004 The problem with the lousy interactivity is, that Houdini is always subdividing the whole object. Maya on the other side checks, which vertices have moved and can then compute the subdivision locally and keep the already subdivided triangles, that are not affected by the edit operation. This improves the performance dramatically. What Houdini in my opinion could benefit from is a message-passing system, so that operators (like the edit-SOP) can tell downstream operators (like the subdivide-SOP) which part of the model has changed. The downstream operator can then either compute a whole new model or it can update its cached solution of the old model. Quote Link to comment Share on other sites More sharing options...
sibarrick Posted November 18, 2004 Share Posted November 18, 2004 Do you get any speed improvements if you use a visibilty sop to display only the area you are working on. Haven't done subd for a bit, my recollection was it didn't help, but might be worth a look see just to check. Quote Link to comment Share on other sites More sharing options...
