Marker trait for CSG backends.

Each backend defines a zero-sized marker type implementing this trait, specifying the concrete 3D and 2D output types and operations.

Required Associated Types

type CsgType

3D solid type produced by this backend.

type SketchType

2D sketch / cross-section type produced by this backend.

fn scale(csg: Self::CsgType, factors: DVec3) -> Self::CsgType

fn mirror(csg: Self::CsgType, axes: DVec3) -> Self::CsgType

fn translate_2d(sketch: Self::SketchType, offset: DVec3) -> Self::SketchType

fn rotate_2d(sketch: Self::SketchType, angles: DVec3) -> Self::SketchType

fn scale_2d(sketch: Self::SketchType, factors: DVec3) -> Self::SketchType

fn mirror_2d(sketch: Self::SketchType, axes: DVec3) -> Self::SketchType

fn color(csg: Self::CsgType, color: [f32; 4]) -> Self::CsgType

fn color_2d(sketch: Self::SketchType, color: [f32; 4]) -> Self::SketchType

fn extrude( sketch: Self::SketchType, height: f64, twist: f64, scale: f64, slices: usize, ) -> Self::CsgType

fn revolve( sketch: Self::SketchType, angle_degrees: f64, segments: usize, ) -> Self::CsgType

Revolve a sketch about its local Y axis (OpenSCAD rotate_extrude).

Profile-x is the radius from the axis (x ≥ 0 expected; negative-x regions produce undefined results), profile-y the height along it.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
