center: true/false
|

|
If true same as centerXYZ = [true, true, true]
|
||||||
|
|
||||||
|
centerXYZ: Vector of 3 true/false values [CenterX, CenterY, CenterZ]
|
||||||
|
center must be left undef
|
||||||
|
|
||||||
|
height: The 3D height of the Triangle. Ignored if heights defined
|
||||||
|
|
||||||
|
heights: Vector of 3 height values heights @ [angleAB, angleBC, angleCA]
|
||||||
|
If CenterZ is true each height will be centered individually, this means
|
||||||
|
the shape will be different depending on CenterZ. Most times you will want
|
||||||
|
CenterZ to be true to get the shape most people want.
