Hi, I'm using PLplot to produce pictures of longitude, latitude temperature maps for my planetary atmospheres research. I first apply an orthographic projection to the lon, lat coordinates and use the grid so computed as the argument into plshades along with pltr2: plshades(temperature, clevels, fill_width, 0, pltr2, X, Y, 2) Temperature here is known at all longitudes and latitudes for which I have computed the X,Y projection matrices, i.e., T(lon, lat). This is just like example 16. Now, the routine plots the map projection beautifully. However, for further computations, I would really like to be able to extract the projected data, i.e., T in the X,Y coordinate system. What would be involved in modifying the PLplot source code to allow me to do that? Cheers, Curtis |
