Blender -- Breaking Glass Test

How to break a glass... ^^
Bullet = particle system emitter (with bullet mesh object)
Glass = particle system reactor (on collision) + explode modifier.

how do you do this?

Try and error, mostly ;-)

Saw something like this in the Houdini 10 demo reel ( search: houdini smashing glass ) and wanted to know if something along the lines of this could be done with Blender... Positive. But without particle fluids, I haven't found a good way to get the water to splash.

Be careful where you start your particles; how does a glass break when the bullet is in the middle of it. Sorry if I sound really critical, hopefully it's constructive criticism.

@ownmeucannot: No, no, I really apreciate that.

Yet, I guess, that's some kind of optical illusion here. You can see how the bullet stops twice on its course? 1st time when it hits the further away side of the glass, 2nd time on the front facing side.

But you're right anyway, I had to set the moment where the glass breaks manually, and there I had to decide between the frame before the bullet hits the glass, or the frame after... Could've increased the fps, no that I think about it... ;)

why did the bullet slow down when it hit each of the sides? made it looks kinda glitchy

[dr4ziw]

I don't know for sure what happened there. I can only guess that this is due to some of the settings for friction and damping, or some other interaction related setting.

Not So Realistic But I Can Tell You Took Some Time, I'd say About A Well...

@BlenderDefender

Look at NionsChannel. He makes a lot of good tutorials, including glass.

What do you want to know? Basically, all you gotta do is manually model the shards (hint: edge loops, extrude individual faces, extrude all into the other direction, scaled around indivudual center). All the other information you need can be found in the video's description to the right. ;)
