Hi All, I have been playing with openscad, and i love it:) this is my toy project i have been working on: https://github.com/e7dal/tribbles basically what i have done is create a chain of my special triangular blocks,which i will now call a *tribble* after that i created a timeslice function, which animate each added block in it's own time slice. here is a sample image: https://www.flickr.com/photos/e7dal/25135527145/in/dateposted/ here is a sample animation https://www.flickr.com/photos/e7dal/24514525184/in/photostream/ please have a look at the tribbles.scad in animation mode at my repo, to see the animation at work. i wanted to do the same with a random chain of blocks, but that gave me very unexpected results. because the random list of block becomes a new random list and any value $t for a given step. That's why i had to introduce a randomizing variable, which will just disable the whole animation with timeslices, which is not so cool:( i can get the random list from the console and paste it in to new file to see it animating. or to this kind of randomizing in an another tool, and just preview the animation in openscad. these are the questions i have now: - Is there a way to generate random values for a single animation? - Is there any other setting or configuration i am missing? - is there a way to start openscad with a file, directly in animation mode? - what is the best way to calculate/detect collision in openscad, that some of my random blocks are going to be in the same space? and a more general question: - what is the best way make the animation perform faster, for larger amount of blocks? Any help or feedback is welcome, Thanks, Kind regards, Erdal Yildiz

Sorry haven't looked at your code, but; Q1/2. Use the rands(seed_value=) parameter? Q3. Not that I know of. Q4. Complicated trigonometry? Sorry. Q5. Get a faster PC. Use the dump feature and make a video. ----- Admin - PM me if you need anything, or if I've done something stupid...

Q3 : it's messy and requires scripting but i have implemented collision detection by intersecting the two modules i'm interested in and exporting that as STL. If the STL is empty then the two modules don't collide.
