[Plib-users] load 3ds

[lahiani m. <lah...@cs...>]

Hello

 1. I try to write class that use like interface . I mean  the class load 3ds object and the user can ask for :
GetVertexes() ------ return vector ( or something else) with all the vertexes  
GetNormals()--------return vector with all the normals
GetPolygon()--------return all the polygon that make the object
And so on...
The constractor look like:

     ssgEntity *obj
     ssgRoot scene;

Parser(file_name)
{
     obj =  ssgLoad3ds(file_name);
     scene -> addKid ( obj ) ;
     some other things
}

now I want to  use object and get all the vertex text coordinate normal ...
how can I do it ???????
how can I search at the tree?????

i try to use this func to print all to file but it isn't work good
what the meaning of the int 12 in leaf -> print(fdest2,"",12);

void parseFile::readScene(ssgEntity* e)
{
	if ( e -> isAKindOf ( ssgTypeBranch() ) )
	{
		ssgBranch *br = (ssgBranch *) e ;
		for ( int i = 0 ; i < br -> getNumKids () ; i++ )
		{
			 readScene ( (ssgEntity*)br -> getKid ( i ) ) ;
		}
	}
	else if ( e -> isAKindOf ( ssgTypeLeaf() ) )
	{
		ssgLeaf* leaf = (ssgLeaf *) e ;
		//e->print();
		leaf -> print(fdest2,"",12);

	}

}

2. if I have 3ds object let say cub that each vertex in different color. 
How can I get the color of each vertex.  


Thanks
