<h2> <a name="Scene graph dependencies"></a><u>Scene graph dependencies</u></h2>
|
2004-08-04 18:22:55 +08:00
|
|
|
The OpenSceneGraph is composed of core scene graph libraries, plugins
|
|
|
|
|
libraries and demo programs. The core scene graph libraries (osg,
|
|
|
|
|
osgDB, osgUtil,
|
|
|
|
|
osgText, osgParticle, osgSim) are only dependent upon OpenGL and
|
|
|
|
|
Standard
|
|
|
|
|
C++ so should compile straight out of the box on most systems. To run
|
|
|
|
|
the
|
|
|
|
|
examples one will also need to compile osgProducer which adds the
|
|
|
|
|
dependency
|
|
|
|
|
of Producer, and if true type text is required then the freetype
|
|
|
|
|
library
|
|
|
|
|
will be required. The plugins which are used to read and write various
|
|
|
|
|
file
|
|
|
|
|
formats have their own sets of dependencies listed below, some have no
|
|
|
|
|
dependencies
|
|
|
|
|
at all. A plugin is only needed if you need to load that specific file
|
|
|
|
|
format,
|
2003-07-27 07:06:23 +08:00
|
|
|
so it is not critical if you don't have all the required dependencies. <br>

<br>
|
|
|
|
|
Under UNIX you can take advantage of flexibility in the build system
|
|
|
|
|
that allows you to manually define the external dependencies that are
|
|
|
|
|
installed on your system. To override the default dependencies
|
|
|
|
|
copy the Make/dependencies file to a directory of choosing, and then
|
|
|
|
|
point to this file by setting the OSG_DEPENDENCIES environmental
|
|
|
|
|
variable to point to this file. Then edit this file to reflect
|
|
|
|
|
which dependencies are present. i.e<br>
|
|
|
|
|
<br>
|
|
|
|
|
cd /home/osguser/OpenSceneGraph<br>
|
|
|
|
|
cp Make/dependencies my_custom_osg_dependencies<br>
|
|
|
|
|
export
|
|
|
|
|
OSG_DEPENDENCIES=/home/osguser/OpenSceneGraph/my_custom_osg_dependencies<br>
|
|
|
|
|
myfavorite-editor my_custom_osg_dependencies<br>
|
|
|
|
|
<br>
|
|
|
|
|
When editing the file, simple change the no to yes, and visa-versa
|
|
|
|
|
where apporpriate.<br>

<h3> <a name="Windows dependency arhives"></a><u>Windows dependency

|
|
archives</u></h3>
|
|
|
|
|
To make life easier for Windows users, we have put together a .zip
|
|
|
|
|
archives with all the required dependencies which can be download and
|
|
|
|
|
installed somewhere in you system. You'll need to set VisualStudio to
|
|
|
|
|
pick up on the include and
|
|
|
|
|
libs, and the PATH set to pick up in the dll's. Alternatively, a more
|
|
|
|
|
hacky
|
|
|
|
|
but simpler solution is to unpack this archive inside you
|
|
|
|
|
OpenSceneGraph distribution,
|
|
|
|
|
so that all the include files drop into OpenSceneGraph/include, and the
|
|
|
|
|
libs drop into OpenSceneGraph/lib, and all the dll's drop into
|
|
|
|
|
OpenSceneGraph/bin, this way VisualStudio will pick up the files
|
|
|
|
|
simpler through the paths set up inside the workspace and project
|
|
|
|
|
files. The archives can be downloaded here: . .

2004-08-04 18:22:55 +08:00
|
|
|
Follows is the list of dependencies which some of the osgPlugins
|
|
|
|
|
require, note the core osg and viewer do not need the following
|
|
|
|
|
dependencies, you
|
|
|
|
|
only need the following if you require each specific plugin. Note, the
|
|
|
|
|
flt,
|
|
|
|
|
3ds, pic, tga, do not have any dependencies other than Standard C++ so
|
|
|
|
|
will
|
|
|
|
|
compile straight of the bag. Under Linux the majority of the
|
|
|
|
|
dependencies
|
|
|
|
|
below come as standard with distributions so you may not need to
|
|
|
|
|
download
|
|
|
|
|
them at all. Its best to try out a straight compile of the osg, if you
|
|
|
|
|
get
|
2003-07-27 07:06:23 +08:00
|

There is a Performer plugin in this distribution for converting from
|
|
|
|
|
Performer to OSG and from OSG to Performer. This plugin requires
|
|
|
|
|
Performer to be installed and therefore is not compiled by default. If
|
|
|
|
|
you have Performer (available under Linux and IRIX) then edit
|
|
|
|
|
src/osgPlugins/Make to compile under the plugin.
|
