Hello,
I would like to be able to create 3d axes with a perspective to give it
more of a 3d look. The following simplified example demonstrates the
problem I am encountering.
pro test
create_view, az=(20), ay=(0), ax=(-70), zoom=.45, persp=.6
plot_3dbox,indgen(2),indgen(2),indgen(2)
end
This example works fine, except for the following error message that is
produced.
;% SURFACE: Illegal 3D transformation.
Because I�m using similar code in a loop for an animation, the message
is being constantly printed out which doesn�t look good and is probably
slowing down the animation itself. Is there a better way of doing this?
I�ve seen the example on how to create 3d axes on David Fanning�s
website, but it also uses the surface procedure and results in the same
error message when I try to manipulate the perspective. The create_view
procedure consists of a series of t3d commands. It is the last of
these, which moves the origin back to the center of the viewport, that
seems to cause the error message to occur. Again, the only problem is
the error message that is produced when adding perspective to the 3d
axes.
Any suggestions would be appreciated, thanks.
