PlaneType in std::types

An abstract plane.

A plane has a position and orientation in space defined by its origin and axes. A plane is abstract in the sense that it is not part of the objects being drawn. A plane can be used to sketch on.

A plane can be created in several ways:

• you can use one of the default planes, e.g., XY.
• you can use offsetPlane to create a new plane offset from an existing one, e.g., offsetPlane(XY, offset = 150).
• you can use negation to create a plane from an existing one which is identical but has an opposite normal e.g., -XY.
• you can define an entirely custom plane, e.g.,

myXY = {
  origin = { x = 0, y = 0, z = 0 },
  xAxis = { x = 1, y = 0, z = 0 },
  yAxis = { x = 0, y = 1, z = 0 },
}

Any object with appropriate origin, xAxis, and yAxis fields can be used as a plane.
