## Functions
void | cv::viz::computeNormals (const Mesh &mesh, OutputArray normals)
Viz3d | cv::viz::getWindowByName (const String &window_name)
| Retrieves a window by its name. More...
Viz3d | cv::viz::imshow (const String &window_name, InputArray image, const Size &window_size=Size(-1, -1))
| Displays image in specified window. More...
bool | cv::viz::isNan (float x)
| Checks float/double value for nan. More...
bool | cv::viz::isNan (double x)
| Checks float/double value for nan. More...
template<typename _Tp , int cn>
bool | cv::viz::isNan (const Vec< _Tp, cn > &v)
| Checks float/double value for nan. More...
template<typename _Tp >
bool | cv::viz::isNan (const Point3_< _Tp > &p)
| Checks float/double value for nan. More...
Affine3d | cv::viz::makeCameraPose (const Vec3d &position, const Vec3d &focal_point, const Vec3d &y_dir)
| Constructs camera pose from position, focal_point and up_vector (see gluLookAt() for more information). More...
Affine3d | cv::viz::makeTransformToGlobal (const Vec3d &axis_x, const Vec3d &axis_y, const Vec3d &axis_z, const Vec3d &origin=Vec3d::all(0))
| Takes coordinate frame data and builds transform to global coordinate frame. More...
Mat | cv::viz::readCloud (const String &file, OutputArray colors=noArray(), OutputArray normals=noArray())
Mesh | cv::viz::readMesh (const String &file)
| Reads mesh. Only ply format is supported now and no texture load support. More...
bool | cv::viz::readPose (const String &file, Affine3d &pose, const String &tag="pose")
| Read/write poses and trajectories. More...
void | cv::viz::readTrajectory (OutputArray traj, const String &files_format="pose%05d.xml", int start=0, int end=INT_MAX, const String &tag="pose")
void | cv::viz::unregisterAllWindows ()
| Unregisters all Viz windows from internal database. After it 'getWindowByName()' will create new windows instead of getting existing from the database. More...
void | cv::viz::writeCloud (const String &file, InputArray cloud, InputArray colors=noArray(), InputArray normals=noArray(), bool binary=false)
| Read/write clouds. Supported formats: ply, xyz, obj and stl (readonly) More...
void | cv::viz::writePose (const String &file, const Affine3d &pose, const String &tag="pose")
void | cv::viz::writeTrajectory (InputArray traj, const String &files_format="pose%05d.xml", int start=0, const String &tag="pose")
