Module math

Math types and traits used by the crate.

Most of the math types are feature-dependent, so they will be different for 2d/3d and f32/f64.

Constants

DIM

The active dimension.

FRAC_1_SQRT_2

1/sqrt(2)

FRAC_PI_2

The PI/2 constant.

PI

The PI constant.

TAU

The TAU constant.

Traits

AdjustPrecision

Adjust the precision of the math construct to the precision chosen for compilation.

AsF32

Adjust the precision down to f32 regardless of compilation.

MatExt

An extension trait for matrix types.

RecipOrZero

An extension trait for computing reciprocals without division by zero.

Functions

orthonormal_basis

Computes the rotation matrix of the orthonormal basis computed from the given axes.

orthonormal_basis_from_vec

Computes the rotation matrix of the orthonormal basis computed from the given axis.

skew_symmetric_mat3

Computes the skew-symmetric matrix corresponding to the given vector.

Type Aliases
