[src]
pub fn transform_vector3(&self, other: DVec3) -> DVec3
[src]Transforms the given 3D vector, applying shear, scale and rotation (but NOT translation).

instead.
pub fn is_finite(&self) -> bool
[src]
pub fn is_finite(&self) -> bool
[src]Returns true
if, and only if, all elements are finite.
If any element is either NaN
, positive or negative infinity, this will return
false
.
pub fn abs_diff_eq(&self, other: Self, max_abs_diff: f64) -> bool
[src]
pub fn abs_diff_eq(&self, other: Self, max_abs_diff: f64) -> bool
[src]Returns true if the absolute difference of all elements between self
and other
is less than or equal to max_abs_diff
.
This can be used to compare if two 3x4 matrices contain similar elements. It works
best when comparing with a known value. The max_abs_diff
that should be used used
depends on the values being compared against.
For more see comparing floating point numbers.
