I've got a little problem with VTK under Win NT and Win 98.
I've written a little tcl script that reads DTED Level 0 elevation
maps and then visualize them. The problem is that while under Win NT
(with no hw acceleration) it all goes really well (i.e. the rendering
is really appealing, you can see lot of shadows and the contours are
very well defined), under '98 (with a Riva TNT and asus drivers) the
image seem to be quite "undefined", the contours seem to disappear, the
colors seem to be very saturated and with abrupt changes.
What I like to know is, does anyone noticed something similiar before
? Any idea on how to obtain good images under '98 ?
