Plotting in C++

By tmarkovich at Thu, Jul 15 2010 8:02am |

Hi,

I am working with an Oil company in an internship for the summer and as of yet, for plotting, I have used GNUPlot on my macbook but GNUPlot is awfully slow. Some of the guys that I work with are using Seismic Unix and they have a tool called 'ximage' which seems to be very nice and extremely fast but I cannot find any information about porting it to Snow Leopard.

To this end, is there a tool out there that can plot 2D maps of a size 1667x1201 (size of sigsbee model if you're interested) in under a second? ximage seems to be able to do this but I haven't seen much else that can. GNUPlot takes almost a full minute to do this task which for 800 time steps is entirely unacceptable.

EDIT:
This is the link to ximage. I can't find much about how to install it or where I can download the source or any of that.

Probably you should be bit

Probably you should be bit more specific about the software package you are referring to. I have been googling for ximage and what I have found is a sofr developped at NASA which is part of something called Xanadu and they do indeed have an OS X precompiled package! It is that one what are you talking about ?

I have found this reference

I have found this reference to Seismic Unix at apple site http://www.apple.com/science/profiles/tbi/index2.html
The site for Seismic Unix seems to be the Colorado Scool of Mines http://www.cwp.mines.edu/cwpcodes/index.html
Hope this helps,

You may already have gotten

You may already have gotten all this, but just in case someone else is interested:

As mentioned in a previous comment, you can get Seismic Unix at

http://www.cwp.mines.edu/cwpcodes/index.html

Once you unarchive the source code there are some goodies inside. For instance, there is a README for MacOS X installation at:

cwp_su_all_42/src/Portability/README_MAC_OS_X

It dates from 2006, so it may not be flawless for Leopard or Snow Leopard installation, though the principles should not have changed and it should save you a lot of grief.

I believe the ximage tool you mentioned is in the source code at:

cwp_su_all_42/src/xplot/main/ximage.c

The ximage mentioned above was developed by the folks at NASA Goddard and Smithsonian Astrophysical Observatory for X-ray Astronomy. It is a cool set of tools, but probably not applicable to your work in the oil industry.
