Hello Alberto, Alberto Luaces wrote: It doesn't compile out of the box on 64bit, because of the casts from pointer to 'unsigned int'. Changing those casts to 'unsigned long' works, but it is an ugly hack. I could not come up with a better way to store an object's identity. The actual memory location where a node is stored is about the only fixed reference to it. Perhaps defining a pointer type with #ifdef 32 bit typedef unsigned int pointer; #elif 64 typedef unsigned long int pointer; #endif and then using the pointer type everywhere is a better solution.

Re: [osg-users] osgdot - a tool to generate a picture ofascenegraph'sstructure
Hi Alberto, There are docs to help with 32-64 migration, I don't remember now the name but there is a type for the pointers that is defined for both 32 and 64. ( in 64bit is the same size as unsigned long, not portable though ) -- Radu Mihai [EMAIL PROTECTED] On 16-Nov-07, at 4:06 AM, Alberto Luaces wrote: It doesn't compile out of the box on 64bit, because of the casts from pointer to 'unsigned int'.

It doesn't compile out of the box on 64bit, because of the casts from pointer
to 'unsigned int'. Changing those casts to 'unsigned long' works, but it is
an ugly hack.

osgdot -- Output the relations between scenegraph nodes and

This is a small tool that reads in a model file (in any format readable
by OSG) and outputs a text file (graph.dot) that describes the connections
between nodes and some other details. The text file is in a format that
can be read by the dot tool from the graphviz package. With dot you can
generate a picture representing the scenegraph. For example, to generate
a PNG file from the graph.dot file use the command:
dot -Tpng -ograph.png graph.dot
* osgdot takes a single argument, the model file to read
* The graph will show nodes and drawable as boxes, labeled with their OSG
class name. If the node/drawable's getName() method returned a non-empty
string this will also be shown in the node (below the horizontal line).
* Nodes are shown with a thick border, drawables with a thin border
* Nodes or drawables that have a stateset assigned to them will be filled
with a grey color.
* Arrows between nodes/drawables indicate a parent - child relationship.
Arrows from node to node are shown with a solid line, arrows from node
to drawable with a dashed line.
* For drawables of the class Geometry the number of primitive sets held
by that object is shown below the horizontal line.
The graphviz package can be found at http://www.graphviz.org/.
Or check your Linux distro for the package. It also seems to be available
for Windows and MacOS.
Compile (on Linux and using gcc) with:
g++ -W -Wall -o osgdot osgdot.cpp -I osg-dir/include -L osg-dir/lib -losg -losgDB
Version used during development: OSG 2.1.1, graphviz 2.12
