Crate libfive[−][src]

Expand description

A high level wrapper around libfive – a set of tools for solid modeling based on functional representation.

Particulalry suited for parametric- and procedural modeling. An infrastructure for generative design, mass customization, and domain-specific CAD tools.

Example

let f_rep_shape = Tree::sphere(1.0.into(), TreeVec3::default())
    .difference_multi(vec![
        Tree::sphere(0.6.into(), TreeVec3::default()),
        Tree::cylinder_z(
            0.6.into(),
            2.0.into(),
            TreeVec3::new(0.0, 0.0, -1.0),
        ),
        Tree::cylinder_z(
            0.6.into(),
            2.0.into(),
            TreeVec3::new(0.0, 0.0, -1.0),
        )
        .reflect_xz(),
        Tree::cylinder_z(
            0.6.into(),
            2.0.into(),
            TreeVec3::new(0.0, 0.0, -1.0),
        )
        .reflect_yz(),
    ]);

f_rep_shape.to_stl(
    "f-rep-shape.stl",
    &Region3::new(-2.0, 2.0, -2.0, 2.0, -2.0, 2.0),
    &BRepSettings::default(),
)?;

The STL file generated from this code is show below.

Features

ahash – On by default. Use AHashMap for hashing when resolving variable names. Disabling this will fall back to the slower HashMap.
stdlib – On by default. Add an extensive list of higher level operations – the libfive stdlib.

To disable either/both of the above features unset default features in Cargo.toml:
```
[dependencies.libfive]
default-features = false
```
packed_opcodes - Tightly pack opcodes. This breaks compatibility with older saved f-rep files.

Structs

BRepSettings	Boundary representation settings passed to any of the rendering/export functions.
Bitmap	Bitmap representing occupancy in a slice of a `Tree`.
Evaluator	Helper for controlling evaluation of `Variables` on a `Tree`.
FlatTriangleMesh	Flat triangle mesh.
Region2	2D bounding region.
Region3	3D bounding region.
Tree	Tree of operations.
TreeVec2	2D point/vector/normal.
TreeVec3	3D point/vector/normal.
TriangleMesh	Triangle mesh.
Variables	Set of variables to parameterize a `Tree`.

Enums

BRepAlgorithm	The algorithm used for computing a boundary representation from a `Tree`.
Error	A list specifying general categories of errors.

Traits

Point2	Trait to aid with using arbitrary 2D point types on a `Contour`.
Point3	Trait to aid with using arbitrary 3D point types on a `TriangleMesh`.

Type Definitions

Contour	Series of 2D or 3D points forming a polygonal chain.
Result	A specialized `Result` type for `libfive` operations.
TreeFloat	An alias for `Tree`.
