Hello,
I have improved my macro following suggestions given to me regarding the
previous version.
Please find attached test images.
Here is the "internal test" version:
// exclusionTest Macro by [GDS|Entropy] - Release - Internal Version
#macro exclusionTest(ctr,vectorArray,testObject)
#local vectorA = min_extent(testObject);
#local vectorB = max_extent(testObject);
#local i=0;
#while (i<ctr)
#if (((vectorArray[i].x <= vectorB.x) & (vectorArray[i].x >= vectorA.x)) &
((vectorArray[i].y <= vectorB.y) & (vectorArray[i].y >= vectorA.y)) &
((vectorArray[i].z <= vectorB.z) & (vectorArray[i].z >= vectorA.z)))
#if (inside(testObject,vectorArray[i]))
callExternal(ctr,0,vectorArray[i])
#end
#end
#set i=i+1;
#end
#end
//------
#macro callExternal(ctr,option,valueToPass)
// your macros here
#end
This seems to work with spheres, torii, cubes, quartic cyl, etc...
I haven't tested it on more complicated objects.
The source file has a few different versions of that macro, including a
"meta" version with more options and one with #debug text included for ease
of comprehension.
