lygia/color/luminance)Computes the luminance of the specified linear RGB color using the luminance coefficients from Rec. 709. Note, ThreeJS seems to inject this in all their shaders. Which could lead to issues
Use:
luminance(<vec3|vec4> color)
#ifndef FNC_LUMINANCE
#define FNC_LUMINANCE
float luminance(in vec3 linear) { return dot(linear, vec3(0.21250175, 0.71537574, 0.07212251)); }
float luminance(in vec4 linear) { return luminance( linear.rgb ); }
#endif
Use:
luminance(<float3|float4> color)
#ifndef FNC_LUMINANCE
#define FNC_LUMINANCE
float luminance(in float3 _linear) { return dot(_linear, float3(0.2126, 0.7152, 0.0722)); }
float luminance(in float4 _linear) { return luminance( _linear.rgb ); }
#endif
Use:
luminance(<float3|float4> color)
#ifndef FNC_LUMINANCE
#define FNC_LUMINANCE
float luminance(float3 linear) { return dot(linear, float3(0.21250175, 0.71537574, 0.07212251)); }
float luminance(float4 linear) { return luminance( linear.rgb ); }
