    • Field Detail

      • DEBUG

        public static final boolean DEBUG
        Debug flag for region impl (graph.curve)

      • DEBUG_INSTANCE

        public static final boolean DEBUG_INSTANCE

      • MSAA_RENDERING_BIT

        public static final int MSAA_RENDERING_BIT
        Rendering-Mode bit for Region

        MSAA based Anti-Aliasing, a two pass region rendering, slower and more resource hungry (FBO), but providing fast MSAA in case the whole scene is not rendered with MSAA.

        See Also:
        Constant Field Values

      • VBAA_RENDERING_BIT

        public static final int VBAA_RENDERING_BIT
        Rendering-Mode bit for Region

        View based Anti-Aliasing, a two pass region rendering, slower and more resource hungry (FBO), but AA is perfect. Otherwise the default fast one pass MSAA region rendering is being used.

        See Also:
        Constant Field Values

      • VARWEIGHT_RENDERING_BIT

        public static final int VARWEIGHT_RENDERING_BIT
        Rendering-Mode bit for Region

        Use non uniform weights [0.0 .. 1.9] for curve region rendering. Otherwise the default weight 1.0 for uniform curve region rendering is being applied.

        See Also:
        Constant Field Values

      • COLORCHANNEL_RENDERING_BIT

        public static final int COLORCHANNEL_RENDERING_BIT
        Rendering-Mode bit for Region

        If set, a color channel attribute per vertex is added to the stream, otherwise only the static color is being used.

        See Also:
        Constant Field Values

      • COLORTEXTURE_RENDERING_BIT

        public static final int COLORTEXTURE_RENDERING_BIT
        Rendering-Mode bit for Region

        If set, a color texture is used to determine the color.

        See Also:
        Constant Field Values

      • DEFAULT_TWO_PASS_TEXTURE_UNIT

        public static final int DEFAULT_TWO_PASS_TEXTURE_UNIT
