Plots upper and lower surfaces of a layer, calculates and plots the boundary faces

File Information

Intended for 3D geological/geophysical visualisation of layered data and will eventually form part of a geophysical visualisation package.
Run ThreedDemo to get an idea of how to use.

 INPUTS: LayerN: The number of the layer to be plotted
         R: a m*n*k matrix of colour/resistivity data for each layer where
            m*n is the size
            of the grid and k is the layer number
         Z: a m*n*k+1 matrix of elevation data for each layer. Therefore
            Z(:,:,1) gives the topography of the land, Z(:,:,2) would be the
            topography of the interface between layer 1 and layer 2.
            Z(:,:,k+1) gives the topography of the base of the last layer.
         Xn, Yn: m*n matrices of the base grid containing the XY co-ords
         for each point.
                NOTE: Each matrix must be surrounded by NaNs. This could be
                achieved in two ways: 1. Use the NaNMat function
                    2. Plot a pcolor image of the surface
                    and use ginput to draw a polygon of
                    the desired surface. Then use
                    'inpolygon' to replace all those
                    values lying outside with NaN. See
                    the file ThreedDemo for help.
 OUTPUTS: hLight: handle of the light object for manipulating lighting.

Has been tested on large data sets (10000 points). Uses opengl for rendering, but this can easily be changed.
