#'''Select and Render Your Sample'''
#*'''Select:''' If you have used the default Scanco Medical scripts, then 
#:*If your data is on the "data disk" and you can search for your files using the file filter to select a sample and measurement then press "OK".   To open a new file, File --> Open.  
#:*If your data is not in the standard location (e.g., it was copied to the projects disk), then use File --> Read and navigate to find the file to open.
#:*Alternatively you can start the program with a file to open  <code>$ uct_3d myfile_seg.aim</code>
#:<br>
#*'''Rendering:''' 
#:*Use a single click of the left mouse button to start or to stop rendering the sample.  
#:*You can also use the "Start" and "Stop" buttons at the bottom of the options on the left.  
#:*You must stop rendering to change viewing options on the left.
#:<br>
#*<span id="Change_the_View">'''Change View:'''</span> 
#:*To adjust the view, move the "Rotation" and "Elevation" slider bars in the options on the left. 
#:*The slider bar is located above its label.

#*<span id="Change_the_Colours">'''Change Colours''' </span> (Object and Background): 
#:*From the top menu choose "Options" then "Object/Display Properties...".  
#:*A segmented image typically only has two values, 0 (black, background) and 127 (white, object).  To change the colour of the object only, we need to set the value 127 to a specific colour.  
#:*In this example, the slider bar value "1" corresponds with the value 127 and we will set both slider bars to "1" so that we are adjusting values "127 ... 127", in other words, only value "127".
#:*Under "Surface" click on the "white box" to open the "Color Mixing" window.  
#:*Choose the new colour for the object (e.g., orange) and press "OK."  
#:*Close the "Object Properties" window or move it to the side. 
#:*Now re-render the object with a single click of the left mouse button.

#*<span id="Cutplane_and_Subdim">'''Cutplane (left options) and Subdim (top menu):''' </span>
#:*The cutplane and subdim functions allow you to show a cross-section of your object.  
#:*The subdim function tends to work better than the cutplane but is limited to axes of the scan.

#<span id="Save_the_Image">'''Print an Image to File'''</span> 
#*An image must be fully rendered in order to be saved.  
#*From the top menu choose "File" then "Print".  Set the print format to "TIFF" and the directory to "Scratch/Temp" (or another location using the "Specify in Filename" option).  
#*Change the filename to something meaningful then press "OK."

#<span id="Save_for_Animation">'''Auto-Print Images for an Animation'''</span> 
#*Creating an animation involves saving a sequence of rendered images, which can then be compiled into an animated GIF or other video format using various software packages (e.g., Photoshop, Quicktime Pro).  
#*From the top menu choose "Options" and "Animation..." to open the Animation Settings window.  Set the viewing parameters for the start of the animation, fully render the image, then press the "Get Settings A" button.  
#*Set the parameters for the end of the animation, fully render the image, then press the "Get Settings B" button.  
#*Set the number of frames you want, the higher the number frames, the smoother the animation will be, but also the larger the file size.
#*Now setup the auto-print feature.  From the top menu choose "File", then "Print".  Choose "TIFF" for the print format, and the "Scratch/Temp" for the directory (or use the "Specify in Filename").  Specify a filename prefix, to which numbers will be appended for the image sequence.  
#*Activate the "Auto-Print" feature.  Press "OK" then press the "Start Calculation" button on the Animation Settings window.  
#*Do not interrupt the program while the frames are being rendered and saved.  When the program is done rendering all the frames, transfer them to your computer to compile into an animation.
