# Objective Glam has some common and useful types and helpers that are not in the prelude of `bevy_math`. This includes shorthand constructors like `vec3`, or even `Vec3A`, the aligned version of `Vec3`. ```rust // The "normal" way to create a 3D vector let vec = Vec3::new(2.0, 1.0, -3.0); // Shorthand version let vec = vec3(2.0, 1.0, -3.0); ``` ## Solution Add the following types and methods to the prelude: - `vec2`, `vec3`, `vec3a`, `vec4` - `uvec2`, `uvec3`, `uvec4` - `ivec2`, `ivec3`, `ivec4` - `bvec2`, `bvec3`, `bvec3a`, `bvec4`, `bvec4a` - `mat2`, `mat3`, `mat3a`, `mat4` - `quat` (not sure if anyone uses this, but for consistency) - `Vec3A` - `BVec3A`, `BVec4A` - `Mat3A` I did not add the u16, i16, or f64 variants like `dvec2`, since there are currently no existing types like those in the prelude. The shorthand constructors are currently used a lot in some places in Bevy, and not at all in others. In a follow-up, we might want to consider if we have a preference for the shorthand, and make a PR to change the codebase to use it more consistently. |

Bevy Benchmarks
This is a crate with a collection of benchmarks for Bevy, separate from the rest of the Bevy crates.
Running the benchmarks
-
Setup everything you need for Bevy with the setup guide.
-
Move into the
benchesdirectory (where this README is located).bevy $ cd benches -
Run the benchmarks with cargo (This will take a while)
bevy/benches $ cargo benchIf you'd like to only compile the benchmarks (without running them), you can do that like this:
bevy/benches $ cargo bench --no-run
Criterion
Bevy's benchmarks use Criterion. If you want to learn more about using Criterion for comparing performance against a baseline or generating detailed reports, you can read the Criterion.rs documentation.
