Module shapes 

The shapes the scene cycles through: their meshes, colliders and textures.

A shape kind decides three things at once — what the render world draws, what physics simulates, and what pattern the material wears — so the three live together and a new kind is one match arm per function.

Enums

ShapeKind

One body shape of the scene: the mesh it draws, the collider physics simulates, and the texture pattern its material wears.

Constants

BALL_COLORS

The base colors the balls cycle through, as sRGB bytes.

BALL_RADIUS

Every ball’s radius, in metres.

PATTERN_SIZE

The pattern textures the shape materials draw from, in pixels per side: big enough that a pattern reads across a metre-wide body, small enough that sixteen of them stay cheap.

SHAPE_KINDS

Every shape the scene cycles through, in spawn order.

Functions

into_desc 🔒

Lift a raw mesh’s arrays into the owned description the render server takes.

lathe 🔒

A lathe along the y axis: the side wall walks the rings top to bottom, and the caps close whichever ends ask for it, so a cylinder and a cone share one winding story.

pattern_texture

The texture pattern one shape kind wears, tinted with a base color: dots for the ball, a checker for the cube, stripes for the cylinder and rings for the cone. Every pattern puts the accents where the body’s silhouette bends, so the tumbling reads as motion.

shape_body

The collider physics simulates for one shape kind, sized to match its mesh.

shape_kind

The shape kind an index draws from the palette.

shape_mesh

The mesh one shape kind draws. Every kind is about BALL_RADIUS across, so every shape shares one visual weight.

tinted 🔒

Scale a color’s bytes by a factor, for the pattern accents.

uv_cone

A cone pointing up the y axis: an apex ring collapsed to a point on top, a flat base cap below.

uv_cylinder

A cylinder along the y axis: flat caps top and bottom, uvs mapped so a texture wraps the wall and spots the caps.

Type Aliases

RawMesh

A mesh as raw arrays: positions, uvs, colors, indices.
