Class LineInterpolator

java.lang.Object

eu.svjatoslav.sixth.e3d.renderer.raster.shapes.basic.line.LineInterpolator

public class LineInterpolator
extends Object

Interpolates between two points along a line for scanline rendering.

This class calculates screen coordinates and depth values (d) for a given Y position. It supports perspective-correct interpolation by tracking the distance between points and using it to compute step increments.

The comparison logic prioritizes interpolators with greater vertical coverage to optimize scanline ordering.
