The videos from each camera view are shown here and the 3D scene is projected onto each view. When all views cannot fit in the available area, arrows are shown and can be used to move through the available views. Double-click on a view to maximize it. When maximized, the mouse is used to zoom (scroll) and pan (right-click and drag) the view, and clicking on the arrows moves between views. Double-click the maximized view to restore it and show all views. Use Alt + right-click to inspect a view through a magnifying class - the level of magnification is controlled by the mouse wheel and reset with the ‘R’ key.
The 3D scene is rendered here. The mouse is used to rotate (left-click and drag), pan (right-click and drag), zoom (scroll), and inspect (Alt + right-click) the scene. The 3D scene contains the global coordinate system, cameras, and skeletons of each identified and tracked person. The origin of the global coordinate system is a white sphere, the x-axis is a red arrow, the y-axis is a green arrow, and the z-axis is a blue arrow. The scene enviroment, ground, and lighting can be modified from the menu accessed using the button at the top left of the 3D view.
The quick tools are shortcuts to the most common Theia3D commands. The entire processing pipeline can be executed using these shortcuts.
Most Display Menu options can be toggled on and off using the quick tool display buttons.
The menu is divided into eight sections.
File - Commands to load and save data.
Analyze - Commands to process data.
Display - Options to control what is displayed in the video overlays and 3D scene.
Results - Options to display joint angle results or monitor the progress of a batch analysis.
Calibration - Commands to check or process calibrations.
Tools - Commands to enhance, organize, and modify data.
Settings - Access Theia3D preferences dialog.
Help - Access help and program information.
The video data can be played and paused using the play button on the left, or you can scroll through the trial using the timeline slider. The number to the right of the timeline indicates the current frame number, and the playback dropdown allows you to adjust the steps between frames that are displayed. When set to one, every frame is displayed, when set to two, every other frame is displayed, and so on.
Below the playback timeline controller is a status bar which indicates the current status and any ongoing processes.
