Detailed Description

Experimental extensions

Author

Joshua Moerman

Include <glm/gtx/scalar_multiplication.hpp> to use the features of this extension.

Enables scalar multiplication for all types

Since GLSL is very strict about types, the following (often used) combinations do not work: double * vec4 int * vec4 vec4 / int So we'll fix that! Of course "float * vec4" should remain the same (hence the enable_if magic)

Value:

template<typename T> \
    return_type_scalar_multiplication<T, Vec> \
    operator*(T const& s, Vec rh){ \
        return rh *= static_cast<float>(s); \
    } \
     \
    template<typename T> \
    return_type_scalar_multiplication<T, Vec> \
    operator*(Vec lh, T const& s){ \
        return lh *= static_cast<float>(s); \
    } \
     \
    template<typename T> \
    return_type_scalar_multiplication<T, Vec> \
    operator/(Vec lh, T const& s){ \
        return lh *= 1.0f / static_cast<float>(s); \
    }
