This demonstration uses RemoteViz and VolumeViz to render medical data in an HTML5 environment.
Drag and drop the medicalRemoteMPR/Clients/HTML5/index.html file in your favorite HTML5 browser.
In the 3D viewer (Top Left) you can manipulate the volume with your mouse. Use the left button to rotate, CTRL+LEFT to pan and the wheel to zoom in/out.
In all others 2D viewers (Top Right, Bottom Left and Bottom Right) you can change respectively Sagittal, Coronal and Transverse slice number by scrolling your mouse cursor on the slice.
You can also change this default settings by modifying the source code of $OIVHOME/source/Inventor/ViewerComponents.
