    Radiosity algorithms using higher order finite element methods



    Many of the current radiosity algorithms create a piecewise constant approximation to the actual radiosity. Through interpolation
    and extrapolation, a continuous solution is obtained. An accurate
    solution is found by increasing the number of patches which describe
    the scene. This has the effect of increasing the computation time as
    well as the memory requirements. By using techniques found in the
    finite element method, we can incorporate an interpolation function
    directly into our form factor computation. We can then use less elements to achieve a more accurate solution. Two algorithms, derived
    from the finite element method, are described and analyzed
