Comment(by mhampton):
Here's a somewhat recursive example that shows the use of the fisheye
projection and then uses that image as a plane tiling. This needs to be
done in the notebook, or you need to change the DATA directory to
something else.
{{{
T = Tachyon(xres = 800, yres = 600, camera_center = (-2.0,-.1,.3),
projection='fisheye', frustum=(-1.0, 1.0, -1.0, 1.0))
T.texture('t1',color=(0,0,1))
cedges = [[[1, 1, 1], [-1, 1, 1]], [[1, 1, 1], [1, -1, 1]], [[1, 1, 1],
[1, 1, -1]], [[-1, 1, 1], [-1, -1, 1]], [[-1, 1, 1], [-1, 1, -1]], [[1,
-1, 1], [-1, -1, 1]], [[1, -1, 1], [1, -1, -1]], [[-1, -1, 1], [-1, -1,
-1]], [[1, 1, -1], [-1, 1, -1]], [[1, 1, -1], [1, -1, -1]], [[-1, 1, -1],
[-1, -1, -1]], [[1, -1, -1], [-1, -1, -1]]]
for ed in cedges:
T.fcylinder(ed[0],ed[1],.05,'t1')
T.light((-4,-4,4),.1,(1,1,1))
T.show()
}}}
{{{
T.save(DATA+'t1.png')
r2 = os.system('convert '+DATA+'t1.png '+DATA+'t1.ppm')
T = Tachyon(xres = 800, yres = 600, camera_center = (-2.0,-.1,.3),
projection='fisheye', frustum=(-1.0, 1.0, -1.0, 1.0))
T.texture('t1',color=(0,0,1))
T.texture('p1',color=(1,1,1),opacity = .1, imagefile=DATA+'t1.ppm',
texfunc=9)
cedges = [[[1, 1, 1], [-1, 1, 1]], [[1, 1, 1], [1, -1, 1]], [[1, 1, 1],
[1, 1, -1]], [[-1, 1, 1], [-1, -1, 1]], [[-1, 1, 1], [-1, 1, -1]], [[1,
-1, 1], [-1, -1, 1]], [[1, -1, 1], [1, -1, -1]], [[-1, -1, 1], [-1, -1,
-1]], [[1, 1, -1], [-1, 1, -1]], [[1, 1, -1], [1, -1, -1]], [[-1, 1, -1],
[-1, -1, -1]], [[1, -1, -1], [-1, -1, -1]]]
T.plane((0,0,-1),(0,0,1),'p1')
for ed in cedges:
T.fcylinder(ed[0],ed[1],.05,'t1')
T.light((-4,-4,4),.1,(1,1,1))
T.show()
}}}
