# Objective - Fixes #18397 - Supersedes #18474 - Simplifies 0.16 migration ## Solution - Upgrade to Glam 0.29.3, which has backported the `nostd-libm` feature. - Expose a similar feature in `bevy_math` and enable it in `bevy_internal`, allowing `bevy_math`, `bevy_input`, and `bevy_transform` to be unconditional dependencies again. ## Testing - CI --- ## Notes - This includes `libm` as a dependency, but this was already the case in the common scenario where `rand` or many other features were enabled. Considering `libm` is an official Rust crate, it's a very low-risk dependency to unconditionally include. - For users who do not want `libm` included, simply import Bevy's subcrates directly, since `bevy_math/nostd-libm` will not be enabled. - I know we are _very_ late in the RC cycle for 0.16, but this has a substantial impact on the usability of `bevy` that I consider worth including. |

Bevy Mikktspace
This is a fork of https://github.com/gltf-rs/mikktspace, which in turn is a port of the Mikkelsen Tangent Space Algorithm reference implementation to Rust. It has been forked for use in the bevy game engine to be able to update math crate dependencies in lock-step with bevy releases. It is vendored in the bevy repository itself as crates/bevy_mikktspace.
Port of the Mikkelsen Tangent Space Algorithm reference implementation.
Requires at least Rust 1.76.0.
Examples
generate
Demonstrates generating tangents for a cube with 4 triangular faces per side.
cargo run --example generate
