Many OpenGL devices don't support destination alpha. In particular, the OpenGL 1.1 software rendering libraries from Microsoft don't support it. The OpenGL specification doesn't require it. If you have a system that supports destination alpha, using it is a simple matter of asking for it when you create your window.

The initial display mode is used when creating top-level windows, subwindows, and overlays to determine the OpenGL display mode for the to-be-created window or overlay. Note that GLUT_RGBA selects the RGBA color model, but it does not request any bits of alpha (sometimes called an alpha buffer or destination alpha) be allocated.

Oct 26, 2010 · It's the CORRECT way to do regular alpha blending, as the existing GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA mode leads to dark fringes. It does require that images are created with this in mind, so it should probably remain optional. Destination alpha: The frame buffer has an alpha channel which would be useful to get access to, in the blending ...

Mar 17, 2019 · I am writing some API for a piece of new graphics hardware, I try to let it support stencil buffer, but the hardware itself only support scissor test, depth test, alpha test, and a strange destination alpha test, no direct stencil test. I need to make some effect such as reflection&shadow volumn, so I need the stencil buffer. Is there any way that I can implement stencil test in hardware ...

the RGB and alpha components of a blended pixel. OpenGL 1.4 allowed separate RGB and alpha components to support distinct source and destination functions. OpenGL 2.0 generalizes the control to provide separate RGB and alpha blend equations. • Other Specification Changes. OpenGL 2.0 includes several minor revisions and

Blending Advanced-OpenGL/Blending. Blending in OpenGL is also commonly known as the technique to implement transparency within objects. Transparency is all about objects (or parts of them) not having a solid color, but having a combination of colors from the object itself and any other object behind it with varying intensity.
