[JAVA3D] Model Aspect Ratio

[Dean Keeler]

Hi,   I am hoping someone can help me.  I am reposting this message to the group to see if anyone has come across this problem or can give me any insight regarding this issue.   I have an application that creates a virtual world using a vrml file.  I need to run it on a system that uses a 2 monitor display.  Using a 2 monitor display I can set my display resolution to 2048 x 768.  When I run my application on this system, the model aspect ration when the view is rendered is changed and causes the model to appear short and wide.  When i run my application on a single monitor display, the model uses the correct aspect ratio and the model looks fine.  Does the view somehow use the aspect ratio of the display resolution? Can anyone help me with this or give me any ideas?      I've done some more investigation and have found the following:   1. I have been able to reproduce this problem using the "HelloUniverse" sample program on a dual monitor display.  The spinning block appears correctly on a single monitor system and appears short and wide on a dual monitor system.   2. If I scale my model in the X and Y so that is looks short and wide on a single monitor system,  when it is run on a dual monitor system it appears correct.   3. The display card for the dual monitor system is an Appian Jeronimo Pro.   4. When I run the application on the dual monitor system and turn off one of the monitors so that the system thinks it is a single monitor system, the model appears correct.     If you have any question or need clarification, please ask.  I need to get this resolved quickly.   Thanks for any suggestions you can offer, Dean
