virtual void setFadeColor (const vec4 & color) const =0

Sets the current fade color for the scene on the screen. By gradually changing this value it is possible to create "fade in" and "fade out" effects depending on the w component of the given vector. For example, when the following vectors are passed the result will be:

• vec4(1,1,1,1) - a fully white screen. Positive w results in additive blending.
• vec4(0.5,0.5,0.5,1) - light colors on the screen.
• vec4(1,0,0,1) - R channel for all screen colors is to its maximum; G and B without changes.
• vec4(0,0,0,0) - there is no fading (no color alterations are done to the screen).
• vec4(1,1,1,-1) - a fully black screen. Negative w results in scene colors * (1 - RGB), where RGB is the first three components of the passed vector.
• vec4(0.5,0.5,0.5,-1) - dark colors on the screen.

Arguments

• const vec4 & color - Fade color for the scene on the screen. The provided vector represents RGB channel values (first three components) and a fading coefficient (w component). All components are saturated in the range [-1; 1].

The current fade color.
