ArrayVector3GridFromBox

Computes a three dimensional grid of Vector3 positions based on the input box and number of elements.

The total number of elements of the output is 'count x' * 'count y' * 'count z'. Keep in mind that if any of them is 0 then the output array will be empty 0.

The order of the result is determined by the 'order' input. It determines the order in which the components grow.

For example, if the order is set to XYZ the output is the following:

The total number of elements of the output is 'count x' * 'count y' * 'count z'. Keep in mind that if any of them is 0 then the output array will be empty 0.

The first element is created at the 'origin' position.

The order of the result is determined by the 'order' input. It determines the order in which the components grow.

For example, if the order is set to XYZ the output is the following:

000

001

010

011

100

101

110

111.

Tension can be used to tighten up the curvature at the supporting points. 1 is high, 0 normal, -1 is low

bias

Real (1)

The bias can be used to twist the curve about the known points. 0 is even, >0 is towards first segment, <0 towards the other

equal stepping

Bit (1)

Enables constant distances within the discretization of the curve. See also the following parameter, to tweak quality of equal distances..

equal stepping param

Integer (1)

No of discretization steps to determine constant distances. Good values lie between (50...2000), depending on the length of the curve. Higher values mean higher precision, but may slow down the calculation
