Scatter with collision detection

[ChrisJ]

Scatter now has collision detection, which tests intersections with bounding boxes.
I wish this would go faster, but I have to do this in my spare time, around commuting to work for my day job.

Nice to see progress here! I hope we can get control over overlapping, otherwise it's not very useful ;]

So nice to see the development of this great part of corona!Keep Up the good work! :)

Could I put in a request to give the user the ability to change the bounding box to a more complex shape? Kind of like how Mass FX automatically calculates a simple convex / concave hull object  to fit the object better than a simple box. This is especially important when you are scattering more complexly shaped objects - you can see already that no cylinders are scattered near the teapot spout in your example due to using a simple bounding box, so there's a lot of empty space that won't be filled. Overlapping control won't really solve this as it will just cause object intersections where you don't want them to occur.

That would be waaaay more complicated and waaaay slower

I thought it might have been a bit of a long shot. What about letting the user add their own simple bounding object shape? I can sacrifice speed for a super dense and collision free scatter.

I`ve been using the script ultimate painter, which I downloaded from the scriptspot website and it has helped me a lot. It is not actually a scatter, but it allows you to specify a distance in-between the objects, it also has a collision feature too but that one only crashes with me. I am just suggesting that maybe since collision seems to be a long shot for the corona scatter at the moment, maybe just a minimum distance feature/spinner could help some people)

Have you seen this?

ITS FREEEEEEEE!!!!...

Keep the great work ChrisJ.

I look forward to explore the new scatter options. :)

I was thinking of exactly same type of thing + maybe selection between - custom, user made extremely low poly shape resembling original object (tree, grass, bushes, cars, whatever)  - box - cylinder - and maybe even sphere bounding shapes + the ability to set scaling of those + maybe some random scaling of those shapes would be good too, but I guess it will be really slow to calculate even if it would be quite useful in some cases.

Probably the most realistic thing to expect would be the ability to select between box and cylinder shapes and the ability to set scaling of those to semi-manually control overlapping like every other scatterers do + as I wrote before the ability to set some random scaling of those bounding shapes to randomize overlapping a bit would be quite welcome too :)

+1, with rand% eventually
