pub struct Vec3A(/* private fields */);
Expand description
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.
