Direct Known Subclasses:

ForwardOrientedTextBlock, GlowingPoint

public class ForwardOrientedTexture
extends AbstractCoordinateShape

Base class for textures always facing the viewer.

This class implements the "billboard" rendering technique where the texture remains oriented towards the camera regardless of 3D position. The visible size is calculated based on distance from viewer (z-coordinate) and scale factor.

The texture mapping algorithm: 1. Calculates screen coverage based on perspective 2. Clips to viewport boundaries 3. Maps texture pixels to screen pixels using proportional scaling
