Tex Posted April 1, 2016 Share Posted April 1, 2016 I saw the Lego movie recently and thought I'd have a crack at their point cloud sims. As it stands, all the bricks are the same size so I'm trying to work out how to randomize those. Fun stuff! 4 Quote Link to comment Share on other sites More sharing options...
Sierra62 Posted April 1, 2016 Share Posted April 1, 2016 Looks great. The destruction is a nice touch. Quote Link to comment Share on other sites More sharing options...
loopyllama Posted April 1, 2016 Share Posted April 1, 2016 Very cool! It is mildly irritating that I cannot see the rest of the destruction I bet those final frames were really slow to render. Quote Link to comment Share on other sites More sharing options...

Tex Posted August 30, 2016 Author Share Posted August 30, 2016 I actually came back and revisited this one - it was really bugging me I hadn't figured it out! It's a pretty messy solution, there's no instancing and bulk VDB's to calculate out of bounds geometry. To win, you definitely need to attack it on a point level. I had a vague idea of setting the orientation first, running a random set of points through a loop and grabbing the near point based off the orientation - you would also need a statement to figure out if pieces will fit or not. If anyone has ideas I'd be interested to hear. I've attached the scene file if anyone wants to check it out. legoify.hipnc 1 Quote Link to comment Share on other sites More sharing options...
mestela Posted August 31, 2016 Share Posted August 31, 2016 Ha, great work man! you've pushed past the 'easy' bit of doing lego, and got deep into the interesting stuff that helps differentiate 'real' lego from typical 'cg' takes on lego. Re your hunch of a better method, it's pretty much what i did last week. I had the advantage that it was (a) a flat grid rather than a specific 3d shape, (b) was all using the same bricks and (c) wanted gaps left behind where i'd deleted stuff rather than having it all filled, but the core idea worked well. Promptly got replaced by another technique (known as 'stealing pre-existing shapes from the modelling department and blatting it onto surfaces), but still, thats the joy of production eh?

Tex Posted September 1, 2016 Author Share Posted September 1, 2016 Thanks Matt! I'll give it a crack sometime. Points are definitely pretty cool, but I had a thought earlier - seeing as we're playing with symmetrical objects on uniform points, could you use some kind of 3D shader witchery to fake the whole thing?

Tex Posted February 13, 2017 Author Share Posted February 13, 2017 Yeah so I'm still playing with bricks, I'm definitely a square. Nothing fancy, the hardest part was data swapping between different sims. 5 Quote Link to comment Share on other sites More sharing options...
