void printInfo()
Prints detailed information about the model.
bool isTriangularMesh()
bool isQuadrilateralMesh()
Returns whether the mesh is triangular or quadrilateral.
void triangulate()
Subdivides faces so that the mesh consists only of triangular faces.
void getBoundingBox(double expansionRatio, Vec3d * bmin, Vec3d * bmax)
Return a bounding box of the mesh. The tightest fitting box is scaled by expansionRatio. For
expansionRatio=1, one obtains the tight-fitting bounding box.
Vec3d getPosition(int vertexIndex)
Vec3d getTextureCoordinate(int textureCoordinateIndex)
Vec3d getNormal(int normalIndex)
Returns the vertex position, texture coordinate, or normal vector held at index vertexIndex,
textureCoordinateIndex, normalIndex, in the global array of vertex position, texture coordinate, or normal
vectors.
Vec3d getPosition(Vertex & vertex)
Vec3d getTextureCoordinate(Vertex & vertex)
Vec3d getNormal(Vertex & vertex)
Returns the vertex position, texture coordinate, or normal vector for the given vertex.
void setPosition(int vertexIndex, Vec3d & position)
void setTextureCoordinate(int textureCoordinateIndex, Vec3d & textureCoordinate)
void setNormal(int normalIndex, Vec3d & normal)
void setPosition(Vertex & vertex, Vec3d & position)
void setTextureCoordinate(Vertex & vertex, Vec3d & textureCoordinate)
void setNormal(Vertex & vertex, Vec3d & normal)
Sets the vertex position, texture coordinate or normal in the array of global vertex positions, texture
coordinates or normals. Returns the vertex position, texture coordinate, or normal vector for the given
vertex.
Material material(unsigned int index)
Material * materialHandle(unsigned int index)
Returns a copy of or a pointer to the material at index index in the global array of materials.
size t getNum...()
void add...(...)
For each of Vertices, Faces, Normals, TextureCoordinates, Groups, or Materials, returns the number
of them in the object, or adds a new one of them to the object.
void buildFaceNormals()
Calculates the geometric normals of each face (assuming counter-clockwise winding) and caches them in
the ObjMesh::Face objects. This must be done before using any of the vertex-normal generation functions
below.
void buildVertexFaceNeighbors()
void clearVertexFaceNeighbors()
