Function EnableSwizzles

Enables Swizzle operations on Vec2, Vec3, and Vec4 types.

Swizzle operations are performed by using the . operator in conjunction with any combination of between two to four component names, either from the set xyzw or rgbw (though not intermixed). They return a new vector with the same number of components as specified in the swizzle attribute.

Example

import { Vec3, EnableSwizzles } from 'gl-matrix';

EnableSwizzles();

let v = new Vec3(0, 1, 2);

v.yx // returns new Vec2(1, 0);
v.xzy // returns new Vec3(0, 2, 1);
v.zyxz // returns new Vec4(2, 1, 0, 2);

v.rgb // returns new Vec3(0, 1, 2);
v.rbg // returns new Vec3(0, 2, 1);
v.gg // returns new Vec2(1, 1);
