Hello Guys!  I was wondering if there is a way to profile our CGA code, is there a way to determine the number of calls for specific function, time spent in each function, etc. For example: Also I came across something that I am not sure if the call is being done one or three time getScopeInWorld =      [ convert( x, scope, world, pos, 0,0,0 ) ,        convert( y, scope, world, pos, 0,0,0 ) ,        convert( z, scope, world, pos, 0,0,0 ) ] print( [ getScopeInWorld[0], getScopeInWorld[1], getScopeInWorld[2] ] ) is getScopeInWorld evaluated three time or one time? ...

I have a problem, where I am using convert() to convert scope to world space, apply some world space operation, and then convert it back to scope. based on shape orientation, it either works or behave with unexpected results. Here is my test case /** * File: transformBug.cga * Created: 8 Jul 2020 11:07:40 GMT * Author: dave.lajoie */ version "2019.1" getScopeInWorld = [ convert( x, scope, world, pos, 0,0,0 ) , convert( y,

apply some operation on world xyz, and then convert it back to scope space. Assume the following shape ( oddly rotated in all three axis , and translated in 3D space ) where the shape is 60x0x60 in size I need to flatten the shape in Z, and then extract the scope origin(xyz) in world space, then quantized the xyz to a specified float modulo, then convert back from world xyz into scope space, so I can reset the modified scope to align with the quantized world space coordinates. ( shown by orange arrow ) I was hoping I could use convert() to the conversion back and forth between scope and world. I am sure I am missing something silly. Tx Dave. ... View more

Hello Everyone, is there a way to split using world space slicer position instead if using the local scope? I want restrict the split() on X and Y along specific world space modulo ( for example: at each 3.455 on X and 3.455 on Y ) This is what I would expect as result however as soon as the shape isn't regular, all break loose, and the local scope kicks, and the slicing axis realigns to the local scope. How can i force the local scope to be aligned with the world XYZ axis when splitting? Tx Dave.
