Getting started§

ncollide relies on the official Rust package manager Cargo for dependency resolution and compilation. Therefore, making ncollide ready to be used by your project is simply a matter of adding a new dependency to your Cargo.toml file. You can either use the ncollide2d crate for 2D geometry or the ncollide3d crate for 3D geometry. You can even use both if you need both 2D and 3D in your application. Note that you will probably need nalgebra as well because it defines algebraic entities (vectors, points, transformation matrices) used by most types of ncollide.

[dependencies]
nalgebra = "0.15.0"
# Choose the one you need, or both.
ncollide2d = "0.16.0"
ncollide3d = "0.16.0"

Until ncollide reaches 1.0, it is strongly recommended to always use its latest version, though you might encounter breaking changes from time to time. Once your Cargo.toml file is set up, the corresponding crate must be imported by your project with the usual extern crate directive:

extern crate ncollide2d; // If you need 2D.
extern crate ncollide3d; // If you need 3D.

Cargo example§

You may use this Cargo.toml file to compile the downloadable examples of this guide. Simply replace example.rs by the actual example’s file name.

[package]
name    = "example-using-ncollide"
version = "0.0.0"
authors = [ "You" ]

[dependencies]
approx   = "0.2.0"
alga     = "0.6.0"
nalgebra = "0.15.0"
ncollide2d = "0.16.0"

[[bin]]
name = "example"
path = "./example.rs"

[package]
