AUTHOR:

- class sage.interfaces.tachyon.TachyonRT¶
Bases:
sage.structure.sage_object.SageObjectThe Tachyon Ray Tracer
tachyon_rt(model, outfile=’sage.png’, verbose=1, block=True, extra_opts=’’)
INPUT:
model- a string that describes a 3d model in the Tachyon modeling format. Type tachyon_rt.help() for a description of this format.outfile- (default: ‘sage.png’) output filename; the extension of the filename determines the type. Supported types include:tga- 24-bit (uncompressed)bmp- 24-bit Windows BMP (uncompressed)ppm- 24-bit PPM (uncompressed)rgb- 24-bit SGI RGB (uncompressed)png- 24-bit PNG (compressed, lossless)
verbose- integer; (default: 1)0- silent1- some output2- very verbose output
block- bool (default: True); if False, run the rendering command in the background.extra_opts- passed directly to tachyon command line. Use tachyon_rt.usage() to see some of the possibilities.
OUTPUT:
Some text may be displayed onscreen.
The file outfile is created.
EXAMPLES:
- __call__(model, outfile='sage.png', verbose=1, extra_opts='')¶
This executes the tachyon program, given a scene file input.
INPUT:
model– string. The tachyon model.outfile– string, default'sage.png'. The filename to save the model to.verbose– 0, 1, (default) or 2. The verbosity level.extra_opts– string (default: empty string). Extra options that will be appended to the tachyon commandline.
EXAMPLES:
sage: from sage.interfaces.tachyon import TachyonRT sage: tgen = Tachyon() sage: tgen.texture('t1') sage: tgen.sphere((0,0,0),1,'t1') sage: tgen.str()[30:40] 'resolution' sage: t = TachyonRT() sage: import os sage: t(tgen.str(), outfile=os.devnull) tachyon ...

- help(use_pager=True)¶
Prints (pages) the help file written by John Stone describing scene files for Tachyon. The output is paged unless use_pager=False.
- usage(use_pager=True)¶
Returns the basic description of using the Tachyon raytracer (simply what is returned by running tachyon with no input). The output is paged unless use_pager=False.
