14 Apr Loading a Xml scene with SFE
Loading a SOFA Xml scene with SFE is quite straightforward and can be done in only a few lines of code.
First, you have to include the SFE header. Note that depending on your version of SFE, the name of the file to include might change.
1 | #include <sfe/Simulation.h> |
Then you have to create the simulation object and ask it to load your xml file, in this case, “cubes.scn”.
2 3 4 5 6 | int main ( int argc, char** argv ) { sfe::Simulation simulation = sfe::getSimulation(); simulation.loadFile( "cubes.scn" ); } |
And that’s it!
To be convinced that your scene is actually loaded, you can display the scene graph in the console. For instance by calling the following method.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | void print_node_subgraph( sfe::Node node, const std::string& tab ) { // Print the name of the current node std::cout << tab << node.name() << std::endl; std::string newtab = tab + "\t"; // Print the name of all its objects for ( auto object : node.objects() ) std::cout << newtab << object.name() << std::endl; // Process of all its children for ( auto child : node.children() ) print_node_subgraph( child, newtab ); } |
