Surface Decoration

The Surface Decoration node generates the skin (mesh) for the plant skeleton.

• Meshing: Converts the line graph into a watertight tube mesh.
• UVs: Automatically generates UV coordinates for textures.
• Displacement: Supports noise-based displacement for bark detail.

Concept

From Lines to Tubes The simulation produces a wireframe skeleton. Surface Decoration turns this into renderable geometry by sweeping a profile along the curves, respecting the width attribute calculated during growth.

Inputs

• Input 0 — Graph The growth graph.
• Output — Graph The graph with surface generation instructions.

Parameters

Meshing

• Divisions: Radial resolution of the tube.
• Adaptive: Optimize polygon count based on curvature.

UVs

• Scale: Tiling factor for textures.
• Offset: Shift UVs.

Displacement

• Texture: Path to a height map.
• Strength: Displacement amount.

Attributes

• Consumes: width, P, orient.
• Generates: uv, N (normals) on the output mesh.

Workflow

1. Connect Surface Decoration to the Decoration socket of a Grow node (usually the Trunk).
2. Simulate the graph.
3. The output will include the generated mesh.
