Circuit board traces with travelling pulses
In your harnessGodot shaderMIT
Printed circuit board surface: a cell grid of random copper traces (straight runs, corners and via pads) on solder mask, with emissive signal pulses running along the traces.
What it takes and gives
- Shader type
- spatial
- Parameters
- board_color (vec4 = 0.04, 0.22, 0.12, 1), copper_color (vec4 = 0.78, 0.6, 0.3, 1), pulse_color (vec4 = 0.3, 1, 0.9, 1), cells (float = 14), trace_width (float = 0.09), via_radius (float = 0.18), pulse_speed (float = 1.2), pulse_share (float = 0.45) and 1 more
- Use it on
- A mesh with UVs.
- Result
- A green board covered in copper lines, corners and rings with cyan sparks running along some lines.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/circuit_trace_pulses/
Limits. Traces are chosen per cell independently, so many end at cell borders without connecting; it reads as decoration, not a routed circuit. Thin traces alias at small sizes.
