◆ read_OBJ() [1/2]
template<typename Graph , typename NamedParameters = CGAL::parameters::Default_named_parameters>
#include <CGAL/boost/graph/IO/OBJ.h>
reads the graph g
from the file fname
, using the Wavefront Advanced Visualizer Object Format (OBJ).
The data is expected to represent a 2-manifold (possibly with borders).
Ignores comment lines which start with a hash, and lines with whitespace.
- Attention
- The graph
g
is not cleared, and the data from the file are appended.
- Template Parameters
-
- Parameters
-
fname | the name of the input file |
g | the graph to be built from the input data |
np | optional Named Parameters described below |
- Optional Named Parameters
-
a property map associating points to the vertices of
g
-
Type: a class model of
WritablePropertyMap with boost::graph_traits<Graph>::vertex_descriptor as key type and Point_3 as value type
-
Default:
boost::get(CGAL::vertex_point, g)
-
Extra: If this parameter is omitted, an internal property map for
CGAL::vertex_point_t must be available in Graph .

-
whether extra information is printed when an incident occurs during reading
-
Type: Boolean
-
Default:
false
| |
- Returns
true
if reading was successful and the resulting mesh is valid, false
otherwise.
