Collision Constraint custom operator

[mic]

Hi

This is my first post I've been a long time lurker of this forum. I thought I would share with you guys a little script I wrote in my free time.

It is just a very basic collision detection custom operator for Softimage written in Python. I've heard animators ( or other departments after them ) complain so much about feet not making contact with the ground because they don't have time to check due to super tight deadlines. Anyway, it was a great exercise in trying to learn how custom operators work and in the process I got a better understanding on Quaternion rotations. Just copy to your workgroup or user "\Application\Plugins" folder and restart Softimage.

Anyway here is a video on how to use it:



Thanks for looking

That looks very handy! I'm not an animator but if I was I'd be trying that.

Welcome to the forum!

One question. Would it be possible to do this with individual points in and object (like footprints in snow for example)?

There could be a lot of uses like deforming a foot to the ground or just deforming an object to another for modeling purposes.

Hey ActionArt! Thanks for the welcome. What you've mentioned is a really great idea. Only thing is that it's not really the intention of this plugin to provide deformations ( as it's really a constraining plugin). And because it's in the form of a script, there's always speed concerns so something like that would probably be faster done in ICE.

Anyway thanks again for the warm welcome and stopping by.

Hi, FYI, there is already a footprint compound included in softimage

Will have to take a look at that, thanks for reminding me it's already there.

Ported the same Op to a C++ plugin ( sorry 64bit only - If there's enough requests, I can compile a 32 bit version). I've been told that python ops are pretty slow in comparison to JScript or C++. Was great trying to learn the C++ way.

Download at the top of the page. Copy both files to "Plugins" directory.

This looks really nicely implemented - very useful but very simple at the same time. Thanks!

not the same thing AFAIK

Looks great, thanks!

BTW I am asking gurus here, is it possible to reproduce this kind of compound with ICE? Plug-ins could be incompatible with the newer versions of SI but Compounds work. Don't bombard me with answers like "go and try for yourself" I don't know ICE and I don't have time to learn it in the future also because I am focusing on Modeling and rendering instead of FX and kinda stuff. BTW more constrains would always be welcome on my part, I love constraints:)

I think he was responding to the post about adding deformations to the plugin. Anyway, I' pretty sure it is doable in ICE. I could give it a go just learn a bit more about ICE.
