glBlendEquationSeparate Method

Set the RGB blend equation and the alpha blend equation separately.

Namespace:  Ooogles
Assembly:  Ooogles (in Ooogles.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
Copy
public static void BlendEquationSeparate(
	glBlendEquationMode equationRgb,
	glBlendEquationMode equationAlpha
)

Parameters

equationRgb
Type: OooglesglBlendEquationMode
specifies how the red, green, and blue components of the source and destination colors are combined.
equationAlpha
Type: OooglesglBlendEquationMode
specifies how the alpha component of the source and destination colors are combined
Remarks
The blend equations determine how a new pixel (the 'source' color) is combined with a pixel already in the framebuffer (the 'destination' color). This function specifies one blend equation for the RGB-color components and one blend equation for the alpha component.

These equations use the source and destination blend factors specified by either BlendFunc(glBlendFactor, glBlendFactor) or BlendFuncSeparate(glBlendFactor, glBlendFactor, glBlendFactor, glBlendFactor). See BlendFunc(glBlendFactor, glBlendFactor) or BlendFuncSeparate(glBlendFactor, glBlendFactor, glBlendFactor, glBlendFactor) for a description of the various blend factors.

See glBlendEquationMode for a description of the available options. The results of these equations are clamped to the range 0..1.

The Add equation is useful for anti-aliasing and transparency, among other things.

Initially, both the RGB blend equation and the alpha blend equation are set to Add.
