O.T. Can someone demistify the use of QuickTime VR?

quicktime vr has nothing to do with vrml. they're just panoramic photos or renders that you have to open with quicktime.

Before getting any deeper into all this, I just want to make clear that all I want is to create 3D objects for VRML (that I can rotate eventually), but to be viewed with QuickTime. Ok, now that that it's been stated...

Thank you pgraham, this is just what I was moments ago finding out at the Developer Connection (http://developer.apple.com/documentation/QuickTime/InsideQT_QTVR/0Preface/chapter_1_section_1.html) of Apple.
What confuses me is that I have the vague impression that I had experienced a VRML file with QuickTime, also finding webpages with this titles: "VRML & QTVR getting married (http://www.itl.nist.gov/iaui/ovrt/projects/vrml/vrml_qtvr.html)".

Would it be fair to say that QuickTime VR handles both VRML & QTVR?

Doing a quick search in the 3DSMax8 Help file I see it can export to panorama movies, but there in that page nothing is mentioned about 3D objects in VRML.
I have been exporting to VRML from Max, so I can clearly see how they are two different things.

Do you know how to create VRML files (3d objs that can be rotated in any angle) for QuickTime?

there is another type of QTVR file, called an object movie, that contains pictures of an object from many angles. it displays the images based on how you drag the mouse, so it appears to be 3d. Apple has one for all of their computers, like this one for macbook (http://www.apple.com/macbookpro/gallery/qtvr17.html). This is just a series of images. VRML contains geometry that can be rendered from any viewpoint.

Here's an apple page (http://developer.apple.com/documentation/QuickTime/InsideQT_QTVR/3Chap/chapter_4_section_5.html#//apple_ref/doc/uid/TP40000944-CH207-TPXREF119) that outlines the process of creating an object movie.

pgraham,

Right, that's just what I had found too :)
I think I see this whole thing more clearly now: VRML is not the same thing as an Obj Movie. An Obj Movie looks like VRML but it's really not, and therefore it's created with different tools, and seen with different viewers.

Thanks a bunch pgraham :)
