Hallo!
Who knows what I am doing wrong?
I am displaying a volume with following commands:
read,unit,vol vertices,po; get the volume
vol_value=160 ; isosurface value
SHADE_VOLUME,vol,vol_value,vertices,polygons,/VERBOSE
volsize=SIZE(vol) ; info about vol
SCALE3,XRANGE=[0,volsize(1)],YRANGE=[0,volsize(2)],ZRANGE=[0 ,volsize(3)]
; setup 3D
TV,POLYSHADE(vertices,polygons,/T3D) ; visualization
As far as good, but now I want to zoom:
zoomfactor=1.2
TV,POLYSHADE(vertices*zoomfactor,polygons,/T3D)
For 0 < zoomfactor < 1.1 (in most cases) there is no problem,
but when I increase zoomfactor to 1.2 (thats depends on the
!P.T) I get following chrash message:
Event for Zoom
% POLYSHADE: Vertex 1745: X,Y out of range.
% Execution halted at: MAIN13_EVENT 469 otf.pro
% WIDGET_EVENT
% XMANAGER 469
/soft/local/IDL_4.0_NET/idl_4/lib/xmanager.pro
% OTF 716 otf.pro
% $MAIN$
When I look to vertices, I can't see where they are out of
range, because I don't know the limit, which POLYSHADE has.
How can I 'zoom' with POLYSHADE without having attention to
the x,y-sizes of the draw-window? Is the are NOCLIP-switch?
Does anyone has the source code of polyshade or know how the
message POLYSHADE: Vertex 1745: X,Y out of range is produced?
Any help appreciated to ao@eurad.uni-koeln.de
Thanks!!
