Hi all
Don’t know if this is the correct place to post this, but I am sure bgdm will lock it if its not.:rolleyes:
Just wondering if it would be possible to implement “Cut maps” : Say I want to cut a plane in the pattern of a bullet impact, so when a bullet hits the glass it shatters or breaks in a convincing pattern.
I don’t have any programming ability myself, so don’t know if this would have to be in python or actual program code.
Or can this already be done?

I really have no clue to be honest. But it sounds like something for the physics engine? Pre-shatter the glass and slam it with a projectile. But maybe that’s just me. The practical approach, that’s the way to go. 
Pre shattering the glass is the whole idea, I was thinking about a automatic cutting system, you supply the map, it cuts the plane or whatever.
create a map with the shatter pattern in a paint program, apply it to say a plane, auto cut then pre cuts the plane to the pattern on the map.

:: Maybe not so complecated as the attached image, but it gives the idea.
Ohhhh, I see. That would be good. How do you do that?
subdivide and decimate your plane using fractal options. Then separate them into separate objects. Smash away and let Blender do the calculations.
Note that stuff is pulverized at the point of imact into smoke particles, so you might want to move the hole meshes to another layer and then at the pont of impact, NOT render them from that point forward, supplying a particle mist instead.
hmm, fractals are fractals. Might look ok.
Another thought. Take the 2D graphic into a vector tracing application like Corel Draw, trace, export to curves and go from there. There could still be considerable detailing depending on blenders import etc. Considerably high poly count too.
