Description​

A 2D rhombus (diamond) shape primitive.

Creates a diamond shape centered at the origin with vertices at:

  • Left: (-0.5, 0.0)
  • Top: (0.0, 0.25)
  • Right: (0.5, 0.0)
  • Bottom: (0.0, -0.25)

The shape spans 1.0 units horizontally and 0.5 units vertically.

``` (0, 0.25) /\ / \ / \ (-0.5,0) (0.5,0) \ / \ / \/ (0, -0.25) ```

Default primitive type is Lines (wireframe rendering).
