    Re: tesselate VG path data to triangles

    ShivaVG uses stencil buffer (as explained in the redbook). Instead, you should look at the gluTess code.

    Re: OpenVG on X window

    ShivaVG doesn't triangulate paths; this library performs non-simple, concave, holed, ... polygons rendering using this stencil buffer tecnique.

  5. Re: Building a complex 2D-only GUI on top of OpenGL ES

    It seems that floating point precision doesn't affect the rendering of this test case.

    It's clear that joins between two path segments (of any kind) and 'smooth interpolated' joins that take...

    Re: :)

    If you really use a 64x multisampling for the AA, I believe that your bottleneck is on the pixels not on the edges. Anyway, are you sure that the Flash Player rasterizer doesn't decompose quad-bezier...

    Re: A new OpenVG have launch

    On my old P4, 80ms/frame (without blit) for a 480x640 Tiger (with 16x AA?) isn't so 'high performance'.
    On the same example, Rasteroid 3.1 (16x AA) is 200% faster than GingkoVG.
