Class ARBDrawBuffersBlend


  • public class ARBDrawBuffersBlend
    extends java.lang.Object
    Native bindings to the ARB_draw_buffers_blend extension.

    This extension builds upon the ARB_draw_buffers and EXT_draw_buffers2 extensions. In ARB_draw_buffers (part of OpenGL 2.0), separate values could be written to each color buffer. This was further enhanced by EXT_draw_buffers2 by adding in the ability to enable blending and to set color write masks independently per color output.

    This extension provides the ability to set individual blend equations and blend functions for each color output.

    Requires OpenGL 2.0 and EXT_draw_buffers2. Promoted to core in OpenGL 4.0.

      • glBlendFunciARB

        public static void glBlendFunciARB​(int buf,
                                           int src,
                                           int dst)
        Provides a way to enable blending and set color write masks independently per color output.

        This call modifies the blend functions associated with an individual draw buffer.

        The error INVALID_ENUM is generated if the buf parameter is outside the range [0, MAX_DRAW_BUFFERS – 1].

        The error INVALID_ENUM is generated if either src, or dst is not an accepted value.

        The error INVALID_OPERATION is generated if this method is executed between the execution of Begin and the corresponding execution of End.

        Parameters:
        buf - an integer that indicates the DRAW_BUFFER to modify.
        src - determines both RGB and alpha source functions
        dst - determines both RGB and alpha destination functions
      • glBlendFuncSeparateiARB

        public static void glBlendFuncSeparateiARB​(int buf,
                                                   int srcRGB,
                                                   int dstRGB,
                                                   int srcAlpha,
                                                   int dstAlpha)
        Provides a way to enable blending and set color write masks independently per color output.

        This call modifies the blend functions associated with an individual draw buffer.

        The error INVALID_ENUM is generated if the buf parameter is outside the range [0, MAX_DRAW_BUFFERS – 1].

        The error INVALID_ENUM is generated if either srcRGB, dstRGB, srcAlpha, or dstAlpha is not an accepted value.

        The error INVALID_OPERATION is generated if this method is executed between the execution of Begin and the corresponding execution of End.

        Parameters:
        buf - an integer that indicates the DRAW_BUFFER to modify.
        srcRGB - the source RGB blend function
        dstRGB - the destination RGB blend function
        srcAlpha - the source alpha blend function
        dstAlpha - the destination alpha blend function
