Data Types

Every module in the Curvy Generator exchanges data through its slots. This page describes all the data types those slots can carry.

Types can inherit from each other. A slot that accepts a Shape will also accept a Path, because Path extends Shape (it carries everything Shape does, plus more). This lets you connect modules flexibly without needing exact type matches.

Inheritance tree:

Root
├── Shape
│   └── Path
│       └── Volume
├── Bounds
│   ├── GameObject
│   └── VMesh
├── VSubMesh
└── Spots

Short descriptions of each type, from a user perspective.

A 2D outline made of sample points. Used for example as the cross-section in extrusions.

Carries:

• Positions - the 2D points of the outline (on the X/Y plane only)
• Normals - the outward direction at each point
• Material and UV settings - what points belong to which material, and what UV to apply

Extends Shape

A 3D curve made of sample points. Used for example as the spine along which shapes are extruded or objects are placed.

Carries everything Shape carries, plus:

• Directions - the forward tangent at each point (where the path is heading)

Extends Path → Shape

The result of extruding a Shape along a Path. Contains the full 3D surface data needed to build a mesh.

Carries everything Path carries, plus:

• Vertices - 3D positions of the surface points
• Vertex normals - surface normals
• Cross distances - relative positions of each point along the cross-section

A bounding box. Used to know the size of a mesh or GameObject, so other modules (like Volume Spots) can place objects without overlap.

Carries:

• Bounds - a Unity Bounds value (center + size)

Extends Bounds

A reference to a Unity GameObject or Prefab, along with an optional local TRS offset.

Carries everything Bounds carries, plus:

• Object - the GameObject reference
• Translate, Rotate, Scale - optional offset applied when placing the object

Extends Bounds

Mesh data ready to be turned into a Unity Mesh. One VMesh can contain multiple submeshes (one per material).

Carries everything Bounds carries, plus:

• Vertices - 3D positions
• UV, UV2 - texture coordinates
• Normals - surface normals
• Tangents - surface tangents
• Sub-meshes - list of VSubMesh entries, one per material

One submesh within a VMesh. Each submesh is associated to one material slot on the final Unity mesh.

Carries:

• Triangles - vertex index triplets defining the mesh faces
• Material - the Unity material to apply

A list of placement points. Each spot tells a module where to place an object and which object from the input array to use.

Carries, per spot:

• Index - which item from the input list to place (0 = first, 1 = second, …)
• Position - where to place it
• Rotation - which way it faces
• Scale - how big it is
