GridHelper

GridHelper ⟵ Line ⟵ Object3D

A helper class for creating grid patterns using Line geometry.
GridHelper creates a two-dimensional grid of lines, useful for visualizing coordinate systems, reference planes, and spatial relationships.

• Configurable grid size and divisions
• Separate colors for center lines and grid lines
• Automatic geometry generation
