            set {_yaw} to yaw of {_view}

                # only happens for this draw call, the original shape is not modified
                # note that this is called once for each shape, hence `drawn shape` and not `drawn shapes`
                rotate shape drawn shape by {_rotation}
                # the shape takes the shortest path to rotate to the desired rotation, but that causes it to appear to rotate as we turn.
                # so we'll correct for it by rotating the shape around the y axis by the yaw of the player
                rotate shape drawn shape around relative y axis by -1 * {_yaw}

Current Features:​

• Shapes:
  • Circles, Ellipses, Spheres, and Ellipsoids
  • Cylinders and Elliptical Cylinders
  • Arcs and Spherical Caps
  • Helices
  • Lines
  • 2D Regular and Irregular Polygons and Prisms
  • Regular polyhedra
  • Rectangles and cuboids
• Drawing:
  • Three styles: outline, surface, and filled. Some shapes only support one or two of these styles.
  • Rotation to any orientation.
  • Scaling and offsetting.
  • Drawing multiple shapes at once.
  • Options for who sees the particles (player specific)
  • Custom particle data and density per shape
    • Full support for SkBee's particle data syntaxes
  • Debug axes for clear visualization of the orientation of your shape.
  • Shapes are only calculated when they actually change, so you can draw the same shape many times without any performance hit.
  • Option to make all calculation and drawing synchronous (async by default)
    • Ability to continuously draw a shape for a timespan (async only)
  • Dynamic locations, so particles can follow an entity with no additional user effort
• Particles:
  • Expression for custom particles
  • Section for custom particles
  • Custom motion for particles (vector, inwards/outwards, [anti]clockwise)

Planned Features:​

• Shapes:
  • Bezier Curves
  • Custom shapes defined by a function or structure
  • "Common but difficult to code" shapes
• Drawing:
  • Combining shapes into a custom shape to be drawn as a single shape.
  • Gradient colour fields, with custom colour nodes.
• Animation:
  • Ability to stretch out drawing a shape over a timespan
  • Set up a pre-made animation in a custom structure, play back with one draw call
