This section describes 3D visualization window as well as classes and methods that are used to interact with it.
3D visualization window (see Viz3d) is used to display widgets (see Widget), and it provides several methods to interact with scene and widgets.
void cv::viz::computeNormals | ( | const Mesh & | mesh, |
OutputArray | normals | ||
) |
Computing normals for mesh.
Viz3d cv::viz::getWindowByName | ( | const String & | window_name | ) |
Retrieves a window by its name.
window_name | Name of the window that is to be retrieved. |
This function returns a Viz3d object with the given name.
Viz3d cv::viz::imshow | ( | const String & | window_name, |
InputArray | image, | ||
const Size & | window_size = Size(-1,-1) |
||
) |
Displays image in specified window.
|

Checks float/double value for nan.
x | return true if nan. |
|
inline |
Checks float/double value for nan.
x | return true if nan. |
|
inline |
Checks float/double value for nan.
v | return true if any of the elements of the vector is nan. |
|
inline |
Checks float/double value for nan.
p | return true if any of the elements of the point is nan. |
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 infromation).
position | Position of the camera in global coordinate frame. |
focal_point | Focal point of the camera in global coordinate frame. |
y_dir | Up vector of the camera in global coordinate frame. |
This function returns pose of the camera in global coordinate frame.
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.
axis_x | X axis vector in global coordinate frame. |
axis_y | Y axis vector in global coordinate frame. |
axis_z | Z axis vector in global coordinate frame. |
origin | Origin of the coordinate frame in global coordinate frame. |
This function returns affine transform that describes transformation between global coordinate frame and a given coordinate frame.
