Re: [JAVA3D] Mouse Zoom does not work with PARALLEL_PROJECTION?

Thanks. I get your point. So is there no way we can zoom an object using other methods if we use the parallel projection.     Regards, Jasmine Kwok ----- Original Message ----- From: Patrick-Emmanuel Boulanger-Nadeau To: [EMAIL PROTECTED] Sent: Thursday, February 13, 2003 11:22 AM Subject: Re: [JAVA3D] Mouse Zoom does not work with PARALLEL_PROJECTION? Try putting two object on the side of each other then zoom one in and out. You'll notice that they actually change position in the Z axis. You just can't perseive (how is it spelled ?) it since the projection is parallel, meaning however far it is it will look the same. It's also refered as an orthogonal projection..   Patrick-Emmanuel ----- Original Message ----- From: Jasmine Kwok To: [EMAIL PROTECTED] Sent: Wednesday, February 12, 2003 8:12 PM Subject: Re: [JAVA3D] Mouse Zoom does not work with PARALLEL_PROJECTION? Hi all!   I'm sorry. There's a slight mistake in my email previously. what I meant simply was that Mouse Zoom couldn't work Parallel projection but was fine with perspective projection. In fact, translate and rotate were fine with both perspective and parallel projection. Zoom is the main cause of problem here.   Jasmine Kwok ----- Original Message ----- From: Jasmine Kwok To: [EMAIL PROTECTED] Sent: Thursday, February 13, 2003 11:06 AM Subject: [JAVA3D] Mouse Zoom does not work with PARALLEL_PROJECTION? Dear all,   does anybody knows if View.PARALLEL_PROJECTION works with MouseZoom?   I have a program which uses MouseZoom, MouseTranslate and MouseRotate. They work fine with both parallel and perspective projection. However, when I change the projection policy to PARALLEL_PROJECTION, only the zoom does not work.  Or do I have to set any other attributes?   Would greatly appreciate your help. Thank you.   Jasmine Kwok
