====== Program Options ======

There are many options for controlling the default settings for Visual3D and for controlling the viewing options. The Program Options dialog can be accessed from the **Edit Menu item**

{{:ProgramOptions.png?400}}\\


There are 3 TAB dialogs in the program options property pages.

===== Default Folders =====

{{:DefaultDataFolders.png}}

Visual3D has 3 categories of folders.

  * Folders that are identified when Visual3D is launched, and which are rarely modified.
  * Default folders that are convenient for may pipelines that specify generic folders
  * Folders that change dynamically as the pipeline executes.

The Visual3D animation display, pictured below, allows you to visualize the movement of target markers, model segments (if defined), and other time-dependent phenomena such as ground reaction force (GRF) measured by force platforms.

{{:3Dviewer.gif}}

Visual3D’s extensive animation capabilities allow you to choose which of many elements are included in the display. The illustration shows a typical combination: global coordinate system (GCS) axes, force platforms, instantaneous GRF vector and butterfly showing how the GRF evolves through time, target markers, and the instantaneous pose of the model (represented in this case by the major bone structures corresponding to each of the modeled body segments). You can interact with the animation display to zoom, pan, and rotate it to any perspective you choose.

Note that the skeleton (representing the model) is the only part of the animation display pictured above, which will not appear if you have not yet associated the movement trial with a model. If all you do is open one movement trial, you can watch the markers move through space, observe their relationship to the position of any force platforms and the GRF they measure. This alone is a very useful tool for data quality control—if the animation doesn’t look right, your motion-capture data may be invalid.

The 3D Animation Viewer is based on the OpenGL Graphics Library.

===== Segment Colorization =====

It is possible to color a segment model or a muscle object based on a signal value.

||A right mouse click in the animation window will cause the following popup to appear. Select **Map Segment Color to a Signal Value**\\ \\ {{:MapSegmentColorMenu.jpg}}\\ \\ \\ the following dialog allows the selection of a Visual3D model object and the associated signal\\ \\ {{:MapColorsToSignalValuesDlg.jpg}}\\ \\ \\ In the above dialog the magnitude of the **Right Hip Power** signal is used to color the **Right Thigh Segment.** Note that it is important to select the **Apply Colorization** button after the segment and signal have been selected.\\ \\ {{:ColoredRightThigh.jpg}}\\ \\ \\ The resulting snapshot from the animation shows the colored right thigh.  ||

===== Target Colorization =====

The motion capture markers are colored based on the TARGET residual value.
