taper operation

Syntax

• taper(height)

Parameters

1. height—float
   How many units to extrude.

Description

The taper operation tapers the shape (i.e. forms a pyramid over a polygon). The first polygon of the first mesh in the geometry asset is taken and tapered along the face normal through the polygon's center of gravity. The scope orientation is set in the following way:

• x-axis direction is kept as much as possible (old x-axis is projected to the face plane)
• y-axis along the face normal (taper direction)
• z-axis normal to the two above

The scope's sizes are adjusted to tightly fit the extruded geometry. If height is < 0, the scope.sy attribute will be < 0 and the taper will be downwards.
