Hi sage-support community!
Recently I've tried the following code at sagecell (permalink
here<http://sagecell.sagemath.org/?z=eJylkMsOgyAQRfdN-g-zE5MJGR9ddMFfdN9QOlYTLQYx1b8vpDX2sTRsmDlwLowHBSdt6tnexeR4UCURzssGjO7Y6bPhu2enRI6ElKb7nZdtc6u9ECUWmKcIJHMEkWFYL-558qNjkfg8QdDdpQkORTJDuDZVNQ4ciiPC0LMZW-1CdUCwvTaNn1UmY7htbQjN1tBVWmyUUnjpn7TcLKXl-0Nfc3DGVjhNy4TiNL55pJ-8SH7vR8PKyzev7UOkT6E7fF4=&lang=sage>
):
t = Tachyon(xres=400,yres=400, camera_center=(2,0,0))
t.light((4,3,2), 0.2, (1,1,1))
t.texture('t2', ambient=0.1, diffuse=0.9, specular=0.5, opacity=1.0, color=(
1,0,0))
t.texture('t3', ambient=0.1, diffuse=0.9, specular=0.5, opacity=1.0, color=(
0,1,0))
t.texture('t4', ambient=0.1, diffuse=0.9, specular=0.5, opacity=1.0, color=(
0,0,1))
t.sphere((0,0.5,0), 0.2, 't2')
t.sphere((0.5,0,0), 0.2, 't3')
t.sphere((0,0,0.5), 0.2, 't4')
t.show()
And this was the result:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-1-d6c906df5871> in <module>()
7 t.sphere((RealNumber('0.5'),Integer(0),Integer(0)), RealNumber('0.2'),
't3')
8 t.sphere((Integer(0),Integer(0),RealNumber('0.5')), RealNumber('0.2'),
't4')
----> 9 t.show()

321 self.save(filename, verbose=verbose, extra_opts=extra_opts)

323 return
324 filename = tmp_filename(ext='.png')
AttributeError: 'module' object has no attribute 'display_image'
Same code works fine at www.sagenb.org: it shows the three spheres
I've searched sage-support, ask sage and trac sage, but couldn't find any
similar issue.
Checking the source code I coded the following workaround within the cell (

):
# t is as above
# t.show() replaced by:
filename = sage.misc.temporary_file.graphics_filename()
t.save(filename)
sage.misc.display.display_image(filename)
Is this a bug in the method show() from the Tachyon class?
Thanks in advance,
