Function glm::builtin::mix_bool [−] [src]

pub fn mix_bool<F: BaseFloat, B: GenBType, T: NumBoolRel<F, B>>(
    x: T, 
    y: T, 
    a: B
) -> T

Selects which vector each returned component comes from.

For a component of a that is false, the corresponding component of x is returned. For a component of a that is true, the corresponding component of y is returned. Components of x and y that are not selected are allowed to be invalid floating point values and will have no effect on the results.

Note

  1. mix_bool is not a GLSL function name. It is a variant of mix function and is introduced becasue Rust does not support function name overloading.
  2. This function works for scalar types too.

Example

use glm::{ bvec4, dvec4, mix_bool };

let a = bvec4(true, false, false, true);
let x = dvec4(1., 1., 1., 1.);
let y = dvec4(2., 2., 2., 2.);
assert_eq!(mix_bool(x, y, a), dvec4(2., 1., 1., 2.));
// works for scalars too.
assert_eq!(mix_bool(1_f32, 2., false), 1.);
