size t getNumVertices()
Returns the number of vertices in the face.
Vertex getVertex(unsigned int vertex)
Vertex * getVertexHandle(unsigned int vertex)
Returns a copy of or a pointer to the face vertex at index vertex.
bool hasFaceNormal()
Returns whether the face has a precomputed face normal.
void setFaceNormal(Vec3d & normal)
Sets the face normal of the face.
Vec3d getFaceNormal()
Returns the precomputed face normal, asserting that it has previously been set.
class ObjMesh::Group Constructed by the ObjMesh constructor. Stores a vector of faces constituting
a group in the .obj file.
void addFace(const Face& face)
Adds a face to the vector of faces.
size t getNumFaces()
Returns the number of faces in the group.
Face getFace(unsigned int face)
Face getFaceHandle(unsigned int face)
Returns a copy of or a pointer to the face at index face.
std::string getName()
Returns the name of the group.
unsigned int getMaterialIndex()
void setMaterialIndex(unsigned int index)
Gets or sets the material index for this group. The index refers to the global array of materials in the
ObjMesh.
void removeFace(unsigned int i)
Removes the face at index i.
class ObjMesh Reads and stores the model information from an .obj file.
ObjMesh(const std::string& filename, int verbose=1)
Initializes the object based upon the contents of the .obj file filename. Throws an ObjMeshException
if any failure occurs during the process.
ObjMesh()
Initializes an empty model.
std::string filename()
Returns the name of the .obj file used to initialize the object. Returns an empty string if the object was
not constructed from a file.
