====== Fun With Graphics ======

Visual3D can read OBJ files. The OBJ file format is a standard graphics object and there are many free OBJ files available on the internet.

== A little fun with the Graphics ==

It is possible to replace the ”bones” with another bone or object file. As a ridiculous example, you can change the pelvis model to display a skull rather than the pelvis bones.

  - Click on the **Browse** button beside the **Model File** edit box.
  - Open the //head.v3g// file.
  - Click **Apply.** A 3D image of a head will appear in place of the pelvis.\\
**Note:** For older versions of the software this will be //head.obj.// Visual 3D accepts either file format.
  - The head will appear upside down because the default segment coordinate system for the head is defined with the top of the head as the distal segment.
  - To re-orient the bone:
  - click on the **Rotate/Scale Graphic Model** button
  - Set the **Horizontal Rotation** to //180//
  - Click **OK** to accept the new rotation value and close the window.\\

  - Restore the pelvis image before proceeding:
  - Change **Model File** back to //pelvis.v3g//
  - Click **Rotate/Scale Graphic Model**
  - Click **Reset.**
  - Click **OK.**

=== Finding your Graphics Folder ===

When Visual3D installs, it loads a series of v3g files onto your computer. If you want to add graphics objects to this folder, you will need to store the graphics files in this folder.

To find the models folder:

  - Go to **Edit -> Preferences**
    - In the **Visual3D Program Options** dialog, go to the **Default Folders** tab
    - **Segment Graphics Folder** is where Visual3D is looking for the graphics objects

**NOTE:** You can change this folder to a different location if needed.
