Re: Problem ID: 5677256 QTVR API Limited to 32-bit



I've actually built QTVR objects (1 or 2) that exceeded the limits of what can be played in 32-bit. So I can see a reason to expand to 64-bit. I obviously don't do this often, because it fails currently. But I know that i could use it (although certainly not on a phone).

Hi Jaime,

I'm trying to imagine a scenario in which QTVR would *need* to be 64-bit capable. There really wouldn't be anything to gain from it, from the 3 seconds of hard thinking about it I just did. I doubt anyone has a QTVR movie over 4Gb in size, and the iPhone is a 32-bit platform.

What did you have in mind?

08-Jan-2008 08:22 PM Jaime Magiera: Summary: The entire QTVR API is stuck in C and 32-bit Steps to Reproduce: Read the warning in QTVR and QTAtom API. Note that the API has not been updated in many years. Expected Results: Expect that Apple sees the potential of QTVR in education, science, entertainment and creativity. Actual Results: Despite a community that wishes very much to still use the technology, null comments or support from Apple regarding the future of the API. Regression: QTVR is suffering regression through neglect. Notes: Now more than ever, QTVR and interactivity can be used in education, science and entertainment. For the past few years, my business (Sensory Research) has been developing applications that utilizes QVTVR and QT Interactive for these exact purposes. I also work for a large university (U of M) that has used QTVR for everything from art to Geological specimens. If you continue to support the API, it can integrate technologies such as X3D and interact the various virtual worlds. The potential of QTVR with iphones and portables is astounding. The two can help sell each other. The money is there and the developers will stay if there is some sort of commitment from Apple. Updating the API to work in 64-bit would really say something to the community. It would also poise Apple to hook a bunch of new talent (developers) and cash in on the virtual cash cow that is grazing out in the commercial world right now. (and again, it's just atoms) Thanks. 08-Jan-2008 10:08 PM Jaime Magiera: Also, I'm a professional member of IVRPA. As a group and individually, we feel a strong desire to continue using QuickTIme VR into the future. In other words, there are strong developer, content creator and user communities that rely on QTVR. thanks.

26-Feb-2008 04:28 PM Stoney Gamble: Engineering has provided the following feedback regarding this issue: The QTVR atom structures have been exposed to 64bit clients in QT 7.4. The intention is for API functionality to remain 32bit.
