[−][src]Struct glam::f32::Vec3A
A 3-dimensional vector with SIMD support.
This type is 16 byte aligned. A SIMD vector type is used for storage on supported platforms for
better performance than the Vec3
type.
It is possible to convert between Vec3
and Vec3A
types using From
trait implementations.

must not be of length zero.

[src]
Performs a linear interpolation between self
and other
based on the value s
.
When s
is 0.0
, the result will be equal to self
. When s
is 1.0
, the result
will be equal to other
.
pub fn abs_diff_eq(self, other: Self, max_abs_diff: f32) -> 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 vectors 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.
pub fn angle_between(self, other: Self) -> f32
[src]

The vectors do not need to be unit length, but this function does
perform a sqrt

to f64
