scale radius curiosity - nayan - 11-19-2021
Hi!
A bit confused with scale radius in property test neighbours or in any other operator.....
in documentation you have expalined
Scale Radius : the neighbor search radius of each particle will be set to each particle’s maximum scale dimension.
that means for e.g. if my particle scale is [5,5,5] then the scale radius should be 5 which makes diameter 10 right?
instead of that I am getting scale radius 2.5.
So can you explain why scale radius is half the scale dimension or I might be understanding it wrong.....

If your scale is [5,5,5] then the radius would be 2.5, yes. [5,5,5] are not radius values, but extents of the bounding box (so in the case of a sphere, diameter).
A [1,1,1] particle will have dimensions of 1unit x 1unit x 1unit (assuming it's a scale value applied to a 1x1x1 object). Scale radius is just [max(scale.x, scale.y, scale.z) * 0.5].

Okey....Thank you for the explanation......cleared my confusion
