X3dsetup Requirements
|
||
|
|
---------------------
|
||
|
|
|
||
|
|
To run lasetup, you will need:
|
||
|
|
|
||
|
|
- the proper version of lasetup. Irix5.3, Irix6.x, Sunultracreator,
|
||
|
|
and IBM versions are available.
|
||
|
|
- a Unix workstation. You should have no problem with Silicon Graphics
|
||
|
|
(SGI) machines. Sun Ultra Creator systems also work. IBM
|
||
|
|
workstations have been problematical in the past. You must have the
|
||
|
|
3D option. It may or may not work, depending on things that I don't
|
||
|
|
understand. I haven't made a DEC version, but it should be possible.
|
||
|
|
HP should work someday when HP starts providing OpenGL.
|
||
|
|
- the OpenGL libraries and associated include files, to wit:
|
||
|
|
- libGL.a, libGLU.a, libGLw.a -or- libGL.so, libGLU.so, libGLw.so
|
||
|
|
- the Motif library libXm.a
|
||
|
|
- the X Window System libraries, libX11.a and libXt.a
|
||
|
|
|
||
|
|
You will also need a 24-bit TrueColor visual, preferably double
|
||
|
|
buffered, available on your machine. You can find out what is available
|
||
|
|
by running xdpyinfo. Also the X server must be running the GLX
|
||
|
|
extension. Extensions are listed near the top of the output of xdpyinfo.
|
||
|
|
|
||
|
|
On some systems, you may need to modify your environmental variable
|
||
|
|
LD\_LIBRARY\_PATH so that all of the libraries can be found at runtime.
|
||
|
|
|
||
|
|
To
|
||
|
|
*compile
|
||
|
|
* the code, you will need the above stuff plus lasetup
|
||
|
|
source.
|
||
|
|
|
||
|
|
You may have to change the paths in the makefile, depending on where
|
||
|
|
your libraries are located. Similarly, you may have to change the
|
||
|
|
makefiles in each of the lasetup subdirectories. You will also need the
|
||
|
|
include files:
|
||
|
|
|
||
|
|
- gl.h, glu.h, glx,h, in /usr/include/GL
|
||
|
|
- GLwMDrawA.h, in /usr/include/X11/GLw
|
||
|
|
|
||
|
|
(On Suns these may be in /usr/openwin/include/....).
|
||
|
|
|
||
|
|
*
|
||
|
|
*
|
||
|
|
*Or
|
||
|
|
*
|

|

If you don't have OpenGL and are the adventurous type, you can get and
|
||
|
|
compile [Brian Paul's Mesa
|
||
|
|
library](http://www.ssec.wisc.edu/~billh/bp/Mesa30.html), to which you
|
||
|
|
can link rather than to OpenGL.
|
||
|
|
|
||
|
|
Since Mesa doesn't support hardware even if it's on your machine, the
|
||
|
|
code will run slowly. But this does eliminate the OpenGL requirement.
|
||
|
|
There is a macro MESALIBS in the makefile that you will have to modify,
|
||
|
|
but it might help you get started. I have compiled lasetup with Mesa, so
|
||
|
|
I know it can be done. :)
