This transforms any finite vector and point to zero. The zero transform is non-invertible.

, rotation

from self

The transform is expected to be non-degenerate and without shearing, or the output will be invalid.
Panics
Will panic if the determinant self.matrix3
is zero or if the resulting scale
vector contains any zero elements when glam_assert
is enabled.

Creates a left-handed view transform using a camera position, an up direction, and a focal point.
For a view coordinate system with +X=right
, +Y=up
and +Z=forward
.
Panics
Will panic if up
is not normalized when glam_assert
is enabled.
sourcepub fn look_at_rh(eye: DVec3, center: DVec3, up: DVec3) -> DAffine3
pub fn look_at_rh(eye: DVec3, center: DVec3, up: DVec3) -> DAffine3
Creates a right-handed view transform using a camera position, an up direction, and a focal point.
For a view coordinate system with +X=right

Panics
Will panic if up
is not normalized when glam_assert
is enabled.
sourcepub fn transform_point3(&self, rhs: DVec3) -> DVec3
pub fn transform_point3(&self, rhs: DVec3) -> DVec3
Transforms the given 3D points, applying shear, scale, rotation and translation.
sourcepub fn transform_vector3(&self, rhs: DVec3) -> DVec3
pub fn transform_vector3(&self, rhs: DVec3) -> DVec3
Transforms the given 3D vector, applying shear, scale and rotation (but NOT translation).
To also apply translation, use Self::transform_point3
instead.
sourcepub fn is_finite(&self) -> bool
pub fn is_finite(&self) -> bool
Returns true
if, and only if, all elements are finite.
If any element is either NaN
, positive or negative infinity, this will return
false
.
sourcepub fn abs_diff_eq(&self, rhs: DAffine3, max_abs_diff: f64) -> bool
pub fn abs_diff_eq(&self, rhs: DAffine3, max_abs_diff: f64) -> bool
Returns true if the absolute difference of all elements between self
and rhs
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.
