[sage-edu] Re: SEG-Y in SAGE
According to http://en.wikipedia.org/wiki/SEG_Y, seg-y is a data format for geophysics. How do you plan on using this in Sage?

[sage-edu] Re: Sage 3.1.1 liveCD
The tachyon raytracing uses the tachyon class, called Tachyon. If you
type Tachyon? you will get a help file.
Sometimes it is nicer to work more directly work with tachyon, which
can be done by creating an instance of that class:
sage: t = Tachyon()
Then you can explicitly control the camera, lighting, raydepth, etc.
There are various examples of this in the documentation - if you do
sage: search_doc('tachyon')
you will get links to these.

[sage-edu] Re: Sage 3.1.1 liveCD
Thanx for all the tips! OK, I tried Tachyon? and the help file works. I also tried rendering some ray tracings as suggested in Tachyon? by constructing t=Tachyon() objects and all works very nicely! Some questions about Tachyon: (1) Is this the same tachyon by John Stone? If so, how is this a python file? I found John Stone's website documenting tachyon and its 12 years old! Was python so robust back in 1997 or even in use? (2) Are there sample scene files for tachyon a la povray? I see many such scenes on the afore mentioned website. (3) Can povray scene files be converted to tachyon format? (4) Was the chess scene in Yi Qiang's demo of dSage (http:// www.msri.org/communications/vmath/VMathVideos/VideoInfo/2988/show_video) made using tachyon or povray? TIA, A.

It's not a Python file. Sage is writing a file which the command-line version of Tachyon reads as input. > (2) Are there sample scene files for tachyon a la povray?

In the tachyon source tarball, there are many example scene files, including the examples shown on the website. > (3) Can povray scene files be converted to tachyon format? I don't know of any way to do this, but that probably is not saying a whole lot. > (4) Was the chess scene in Yi Qiang's demo of dSage (http:// > www.msri.org/communications/vmath/VMathVideos/VideoInfo/2988/show_video) > made using tachyon or povray? It was made using POVray using the DistributedPOVRay class in Sage. Sage can make use of povray if it is installed, but we can distribute it due to licensing issues. --Mike --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "sage-edu" group.

You might find this thread useful: http://groups.google.com/group/sage-support/browse_thread/thread/af6c9cceb022017d/d5a238ed5cc009ff There are also a few examples at: http://wiki.sagemath.org/pics although I think its fair to say that all of them are relatively simple. The tachyon interface has not been used heavily by sage users to date. Keep the questions coming!
