<TITLE>layers added to wxgrass</TITLE>

<BODY>
<FONT FACE="Verdana, Helvetica, Arial"><SPAN STYLE='font-size:12.0px'>I just added the following new display layers to the layer manager in wxgrass: d.shadedmap, d.rumbline, d.geodesic, and d.rast.arrow. This gives the new wxPython GUI layer manager all the same types of layers available in the TclTk GUI except for d.rast.num. <BR>
<BR>
d.rast.num is a problem in the wxPython GUI because it requires a very low resolution rendering (less than 100x100 cells). This is incompatible with the rendering algorithm in wxgrass which keeps a constant GRASS output display resolution that is equal to the display canvas resolution in pixels. This makes for nice looking displays and very fast rendering, but is a problem for d.rast.num. There is probably a way to solve this, but it will take some thought and recoding.<BR>
<BR>
AFAICT, the GUI in wxPython now has equivalent (or better) functionality than the TclTk one with the following exceptions:<BR>
digitizing - actively under development<BR>
georectifying - next on my list<BR>
nviz - could really use some expertise in openGL to reconceptualize and implement this.<BR>
