very good qtvr....

yes too bad the vignetting.... although I don't think you can call it vignetting...

anyway....I find the sunlight too dimmed....

... I have done a quick test and rendered a 360° panorama with a mirror sphere inside a scene --> HDRShop (crop and convert to long/lat) --> PanoCube+PTStitcher (free convert from jpg to mov) and it works without vignetting.

Okay, again, my question, since Micha blew threw it faster than my tiny brain can comprehend... anybody willing to do a tutorial on this, or even a little more detailed explanation? =)

Sounds very interesting .. could you explain about the mirror sphere rendering?? does it mean you have a sphere that acts as a mirror? Where is the camera then?

Thanks

first QTVR on this forum?

Wow .. this is very impressive. Cool way to see architectural vizualisations

Thats simple, just place your camera in the middle of the room and render six square size pictures (kind of the inside of a cube) and put them together in one of the little QTVR freeware softwares like MakeCubic for the Mac OS (sorry no idea what is available for Windows).

Thanks ingo,

I haven't had time to try it yet, but is there anything specific I need to do, like a certain size camera and so forth? I guess just a wide enough lens to make sure the pictures overlap?

That works for the 6 picture one, but I was trying to learn how Micha did the mirror ball test. There's a "tutorial" for it that I saw somewhere, but it basically says, put a mirror ball and render. Personally I have no idea how to do that. Any help?

Your camera needs obviously a horizontal and vertical FOV of 90 deg to get a square picture, as far as i know its a focal length of 13,3 mm; and your picture don't overlap, they just fit perfectly.
Depending on the software you use to put the images together its important how your top and bottom view pictures are rotated.

Micha, could you please please please make a little tutorial on this? I have been trying to compensate the vignetting effect with several different camera settings but no one works.

Thank you Micha

It seems very easy to say, but Maxwell don't accept 90 deg FOV both in vertical and horizontal...

Anyone in this forum has already get a easy method for making QUICKTIME VR/PANORAMAS ?

Thank you very much in advance!

It is possible, see the attached QTVR file.

QTVR Test
(Casual is a free sample from www.lowpolygon3d.com)

You need to set up your camera and let Maxwell render the views (six sides).

The only thing I can't get rid off is the vignetting effect

[misterasset]

SMS, looks good aside from the vignetting...

Which program did you use for the stitching together of the images?

[sms]

Thank you

I have used GoCubic, which can be downloaded here (there is also some additional information available):

... I have no time yet to make a full tutorial, but I will make it later. If I forget, send me a pm in a few days.

Only short: place a chrom sphere in your scene - set your camera top down to the sphere (full quadratic screen of the sphere only) - render the image.
Take this rendering -> HDRShop -> panoramica transformation (abirary rotation x= -90 from mirror ball to long-lat [or read the help/tutorials of HDRShop]) -> ... see above post for the other tools

You need a high resolution for a good VR resolution. A little bit of the ground is not rendered, because the sphere dosn't get it. But you could retouch the long-lat image in photoshop. Most the artefact in the ground is not the problem.

There is also an other way with two chrom sphere renderings of different views, but I never have tested it.

Here my old quick test, very low resolution and simple outdoor scene. You can see the unretouched artefact at the ground.

The new Photoshop CS2 has a filter to get rid of the vignetting effect wich is very cool and accurate, give it a try, it may help.

Cheers
