Procedural wood with growth rings and grain
In your harnessGodot shaderMIT
Solid wood from object-space 3D math: growth rings around a trunk axis with noisy distortion, sharp latewood bands, fine grain streaks along the axis and per-ring colour variation, so cut ends and long sides both read correctly.
What it takes and gives
- Shader type
- spatial
- Parameters
- early_wood (vec4 = 0.78, 0.56, 0.34, 1), late_wood (vec4 = 0.45, 0.26, 0.13, 1), ring_density (float = 18), ring_sharpness (float = 0.7), distortion (float = 0.6), grain_density (float = 140), grain_strength (float = 0.25), axis_tilt_degrees (float = 4) and 1 more
- Use it on
- A mesh whose object Z axis runs along the grain (rotate the node to change it).
- Result
- A plank with arched grain on top and a log end showing concentric growth rings.
- Renderers
- compatibility: compiled and rendered, forward plus: not verified, mobile: not verified
- Placement
- res://baltor/godot_shaders/wood_rings/
Limits. Solid texture in object space: scaling the object scales the rings. No knots, pores or normal relief. Rings are centred on the object origin; offset the mesh to move the pith.
