 Hi All


I've had TS 6.6 for a little while, but just getting round to learning it properly.


I would like to model a moving laser beam cutting through a metal plate, & leaving a cut behind it. I'm thinking that animating a boolean subtraction might work?


Could anyone confirm this, or suggest an alternative?


Thanks

Chris Johnson

Hi Chris,

I have no idea whether you may be able to script booleans in this way but I do think I see an alternate way to accomplish what you want to do.

If your intended output is an animation from a stationary camera viewpoint (as opposed to a shared space simulation) it seems to me that you could already have a finished burned cut in the actual plate model which is masked in some way so that it only appears gradually as the cutting bit (beam nozzle) passes over the plate.

In other words, attaching an image mask (like a pre-rendered image of the UNcut plate on a plane) to the actual cutting bit over the actual CUT plate model might work for your purpose.

If your bit is cutting your plate to the left, for instance, you could have the precut model below the bit with an image plane (as described above) of the uncut plate between the precut model and the viewer and attached to the bit. As the bit cuts left it simultaneously drags with it the image plane of the uncut plate to the left along with it... exposing the cut plate model to the right of it (formerly below the image plane) to the viewer as though the plate was being cut in realtime.

Just a thought, and would take some careful alignment of the image plane / cut model / camera, but should be a practical possibility anyway.

Hope that helps,
