Can someone briefly tell me how to update a texture map on an object? I
am trying to modify Rick Towler's rotating sphere program, posted earlier
on this group (search for "Object Grahpics Roting Sphere" to view the
thread):
http://www.acoustics.washington.edu/~towler/programs/camera_ _define.zip
Here's the initial setup of the globe with an image overlaying it:
;load the texture map
read_jpeg,'earth.jpg' ,texture, /true, /order
help,texture
texmap = obj_new('idlgrimage', texture)
container -> add, texmap
;create the "globe" -
globe = obj_new('orb', radius=1, pos=[0,0,0], color=[255,255,255], $
density=3.0, texture_map=texmap, /tex_coords)
container -> add, globe
How can I change the image after it has been created? I am loading in
new geophysical datasets that I want to use to replace the current map.
I tried destroying and recreating both the texmap and globe objects, but
nothing changes.
Thanks,
Clay
