The create animation menu option will generate the Create Animation form which holds controls for developing custom animations within CatchmentSIM.

 

 

Stream Area Threshold Animation

 

Currently, there is only one type of animation available within CatchmentSIM which is the Stream Area Threshold Animation. This animation displays the effect of raising / lowering the Stream Area Threshold (SAT) and drawing raster stream pixels.

 

The options in the lower panel of the form relate specifically to the adopted animation type. The Direction of Play dictates in which direction the SAT frames will be processed. Add Default Sequence will add 37 SAT frames relating to set proportions of the maximum flow accumulation value in a non linear distribution, whereas Add Linear Sequence will add a linear distribution of frames. The best way to come to grips with the different SAT distributions is to experiment with them. Individual frames can be added and removed using the Custom Sequence buttons.

 

The frame rate can be varied to alter the speed of the animation. The processing space required to process the animation is shown in the top panel of the form.

 

After Create has been selected, CatchmentSIM will attempt to check your available memory to determine if sufficient memory (not hard disk space) is available to complete the animation. With high display resolutions set, even some high end computer may run out of memory creating such animation. If this occurs, you should be warned by CatchmentSIM. To fix this, try setting CatchmentSIM to a smaller window size and recreating the animation.

 

 

 

Play Animation

 

The Play Animation form allows the CatchmentSIM generated animation to be displayed and animated along with the associated display parameter.

 

 

 

 

Save Animation As AVI

 

In the Play Animation form menu there is an option to save the animation as an AVI file. This function will stitch together all the images associated with each frame of the animation using a third party program that is distributed with CatchmentSIM. After this menu option has been selected a prompt will be presented asking you to click OK when the third party application has finished. At this stage a DOS style window should be visible. Once the DOS window says the animation is complete, click OK.
