  • Field Details

    • 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:

    • 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:

    • 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:

    • 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:

    • 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.
