nml::vec4 operator*(float lhs, const nml::vec4& rhs)

Return a vec4 that is the product between a scalar and a vec4.

The product between a scalar and a vec4 is calculated this way:

\(lhs * \begin{bmatrix} rhs.x \\ rhs.y \\ rhs.z \\ rhs.w \end{bmatrix} = \begin{bmatrix} lhs * rhs.x \\ lhs * rhs.y \\ lhs * rhs.z \\ lhs * rhs.w \end{bmatrix}\)

Example

#include "include/vec4.h"
#include <iostream>

int main() {
        nml::vec4 a(1.0f, 2.0f, 3.0f, 4.0f);
        nml::vec4 b = 3.0f * a;
        std::cout << nml::to_string(b) << std::endl;

        return 0;
}

Result:

[3.000000, 6.000000, 9.000000, 12.000000]
