simvx.graphics.renderer.grid_pass

Infinite ground-plane grid overlay for 3D editor viewports.

Draws an anti-aliased XZ grid using a fragment shader SDF approach. Major lines every 10 units, minor lines every 1 unit, with distance fade. X-axis colored red, Z-axis colored blue (Godot convention).

class simvx.graphics.renderer.grid_pass.GridPass(engine: Any)

Renders an infinite XZ ground-plane grid behind scene geometry.

Uses a fullscreen quad with ray-plane intersection in the fragment shader to produce anti-aliased grid lines with proper depth for occlusion.

Initialization

setup() → None

Initialize grid pipeline and shaders.

render(cmd: Any, view_matrix: numpy.ndarray, proj_matrix: numpy.ndarray, extent: tuple[int, int]) → None

Render infinite grid. Call after skybox but before scene geometry.

cleanup() → None

Release GPU resources.
