◆ Color3() [1/10]

G3D::Color3::Color3 ( )

inline

Initializes to all zero.

Referenced by bgr(), clamp(), cross(), max(), min(), neonGradient(), operator*(), operator+(), operator-(), operator/(), and pow().

◆ Color3() [2/10]

inline

◆ Color3() [3/10]

Parameters

any	Must be in one of the following forms: Color3(#, #, #) Color3(#) Color3::fromARGB(#) Color3::fromASRGB(#) Color3{r = #, g = #, b = #) Color3::one() Color3::zero()

In the current implementation, G3D::Power3, G3D::Radiance3, and G3D::Irradiance3 are typedefs for Color3, so Color3 accepts "Power3" and "Radiance3" as a prefixes as well, e.g., Power3(1,0,0).
