glBlendFuncSeparate Method

Specify pixel arithmetic for RGB and alpha components separately.

Namespace:  Ooogles
Assembly:  Ooogles (in Ooogles.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
Copy
public static void BlendFuncSeparate(
	glBlendFactor srcRgb,
	glBlendFactor dstRgb,
	glBlendFactor srcAlpha,
	glBlendFactor dstAlpha
)

Parameters

srcRgb
Type: OooglesglBlendFactor
specifies how the red, green and blue source blending factors are computed. The initial value is One.
dstRgb
Type: OooglesglBlendFactor
specifies how the red, green and blue destination blending factors are computed. The initial value is Zero.
srcAlpha
Type: OooglesglBlendFactor
specifies how the alpha source blending factor is computed. The initial value is One.
dstAlpha
Type: OooglesglBlendFactor
specifies how the alpha destination blending factor is computed. The initial value is Zero.
Remarks
Pixels can be drawn using a function that blends the incoming (source) RGBA values with the RGBA values that are already in the frame buffer (the destination values). Blending is initially disabled. Use Enable(glCapability) and Disable(glCapability) with argument Blend to enable and disable blending.

BlendFuncSeparate defines the operation of blending when it is enabled. ASrcRgb specifies which method is used to scale the source RGB-color components. ADstRGB specifies which method is used to scale the destination RGB-color components. Likewise, ASrcAlpha specifies which method is used to scale the source alpha color component, and ADstAlpha specifies which method is used to scale the destination alpha component. See glBlendFactor for a description of the possible operations.

Note: incoming (source) alpha is correctly thought of as a material opacity, ranging from 1.0, representing complete opacity, to 0.0, representing complete transparency.
