public class Grid2D
extends AbstractCompositeShape

A 2D grid of line segments lying in the XY plane (Z = 0 in local space). The grid is divided into configurable numbers of cells along the X and Y axes, producing a regular rectangular mesh of lines.

This shape is useful for rendering floors, walls, reference planes, or any flat surface that needs a grid overlay. The grid is positioned and oriented in world space using a Transform.

Usage example:

Transform transform = new Transform(new Point3D(0, 100, 0));
Rectangle rect = new Rectangle(new Point2D(-500, -500), new Point2D(500, 500));
LineAppearance appearance = new LineAppearance(1, Color.GRAY);
Grid2D grid = new Grid2D(transform, rect, 10, 10, appearance);
shapeCollection.addShape(grid);

Constructor Details

Grid2D

public Grid2D(Transform transform,
 Rectangle rectangle,
 int xDivisionCount,
 int yDivisionCount,
 LineAppearance appearance)

Constructs a 2D grid in the XY plane with the specified dimensions and number of divisions.

Parameters:

transform - the transform defining the grid's position and orientation in world space

rectangle - the rectangular dimensions of the grid in local XY space

xDivisionCount - the number of divisions (cells) along the X axis; produces xDivisionCount + 1 vertical lines

yDivisionCount - the number of divisions (cells) along the Y axis; produces yDivisionCount + 1 horizontal lines

appearance - the line appearance (color, width) used for all grid lines
