VRHOTWIRES  SPRITEORAMAS TOOL

SPRITEORAMAS

One of the most successful tools in VRHotwires 1.0 was the spriteoramas tool. 

I've probably seen dozens of movies made with it, and such a great variety of photographic techniques!

Oddly, it is only now at 2.0 that documentation for it finally appears.

Let's start by looking at some movies:

I've pretty proud of this movie made with a $750 6 camera rig I invented. 

Dennis Gliksman in France has done great high res work.

A timelapse from a still camera with mirror lensby Ian James Wood . 

The immersivision work is in a leage of it's own Done with a $70,000 rig

Alberto got the ball rolling.His camera was stereo...

 single video camera with mirror lens

Roller Coaster rides from Germany.

So now that we've checked out a few movies, lets make one.

We'll start with the source imagery from my very first sprama. Homescene1mov .

this was my first ever sprama and you'll notice there is 'pulse' to the images...(they wobble) 

this was because they used an automated stitcher that solved each frame a little differently. 

Better to use PTMac and PTBatch two little 39 apps that I've learned could stitch material like
this automatically and without wobble.

Still while noteable for it's crudeness, this movie also points to an eay way to make your first sprama.
All I did was put a video camera on a tripod, and try to put looping animations in each frame.

so

Open VRHotwires
Open the Spriteorama tool
drag homescene1VID.mov onto the white window.
in the spriteorama window press 'done'

your panning video should be done.  

that's probably why so many people have managed to use the spriteorama tool without docs,
all you have to do is press done. 

But now we have some more advanced features.

The ability to add autopan and directional sound to your movies.

AUTOPAN

try this tool just check one of the boxes, and go back ot the spriteorama
tab and press done. you can adjust your pan speed and how long it takes
to restart your movie.

Direcional Sound

This feature is a little tricky and new. 

The problem is that spriteoramas don't use pan angle, so we have to generate
a value between 1 and 360 to simulate pan angle

That's what will happen if you check the check box and go back and press done.

You can see the number by going to qt player

and looking at the debugstr value that comes up.

decide where you want your sound to be placed next time from this value.

now make your movie again and use that value.
