Struct Geometry 

pub struct Geometry;

Primitive geometry generator. Call a static method, get back vertices + indices ready for MeshData.

Implementations

impl Geometry

pub fn cube(size: f32) -> (Vec<Vertex>, Vec<u32>)

Axis-aligned box centered at origin.

pub fn box_(width: f32, height: f32, depth: f32) -> (Vec<Vertex>, Vec<u32>)

Axis-aligned box with independent dimensions, centered at origin.

pub fn sphere(radius: f32, segments: u32) -> (Vec<Vertex>, Vec<u32>)

UV sphere centered at origin.

segments controls both horizontal (longitude) and vertical (latitude) subdivisions. 16 is low-poly, 32 is smooth, 64 is high quality. Total triangles ≈ 2 × segments².

pub fn plane(width: f32, depth: f32) -> (Vec<Vertex>, Vec<u32>)

Flat plane on the XZ plane (Y = 0), centered at origin.

pub fn cylinder( radius: f32, height: f32, segments: u32, ) -> (Vec<Vertex>, Vec<u32>)

Cylinder along the Y axis, centered at origin.

pub fn torus( major_radius: f32, minor_radius: f32, major_segments: u32, minor_segments: u32, ) -> (Vec<Vertex>, Vec<u32>)

Torus (donut) centered at origin on the XZ plane.

major_radius is the distance from the center to the tube center. minor_radius is the tube thickness.

pub fn grid( size: f32, divisions: u32, subdivisions: u32, line_width: f32, ) -> (Vec<Vertex>, Vec<u32>)

Flat grid on the XZ plane (Y = 0) centered at origin.

Generates thin quad strips for each grid line — both major and minor subdivisions. Lines have vertex color baked in (gray for minor, brighter for major, red for X axis, blue for Z axis).

size is the total extent (grid goes from -size/2 to +size/2). divisions is the number of cells along each axis. subdivisions is the number of minor lines per cell. line_width is the thickness of each line quad.
