With this tool, you can place points on the 2D images. Points will be created under the cursor either with the left mouse button, or when you press the “Insert” key of the keyboard. Alternatively, pressing the right mouse button, or the “Delete” key of the keyboard will delete the point under the cursor (or the closest point if none is under the cursor). You can also use the mouse to drag a point.
The points are created in 3D space using the image’s origin, orientation and the pixel dimensions. The list of created points is shared between the Basic Module’s Point mode and the 3D Module’s Point mode. Points created on the 2D images will be visible in the 3D space and inversely, points created on the 3D surfaces will be visible on the 2D images.
Points can also be read from a file or manipulated from the command line.
