HELP Rotate the screen 90 degree

Hi

Does anyone of you knows how I can Rotate the content
of my screen in order to have my realtime 3D render to
look straight when I put my screen on the side ????

It may sond weird but I'm finishing a 6 month work on
a 3D file for some kind of theatre play and I just learned today
(2 DAYS BEFORE THE 1ST REHEARSAL !!!) that all the 2D
composition was made fliped at 90Degree and then that the
projectors will stand on theyre side :-O

I could just spin the whole composition 90 degrees but I have tones
of parametrer to change. so if you guys have an idea, a software or
something, please help.

you can check the project on
http://www.marceliantunez.com/
it's called POL

thanks
 
You can map a whole surface on a polygon as you do with a texture.
Draw your 3d content in a buffer not shown and then draw it on a quad big as the screen (rotating the texture of course).

Q8]
 
First of all, I can't seem to find any info at that site, but ...

In D3D (I'm positive it's similar in OGL), I'd eighter rotate the Camera, or set up a projection matrix which does the 90 degree rotation.
Projection is tend to change less so it might be easier to tweak.

If you specify what system do you use it would be easier to help.
 
thanks for those fast replies

I'm using a DirectX engine with a software called Virtools.
The idea of projecting the render into a single poly as a
texture sound good, I should try. But on the other hand
it might take a lot of resources.
I thought more of some tools like PowerStrip or something,
or a NVidia utility...

I'm running this on Win 2000, sp2, DirectX 8.1, Geforce 4 4400,
Pentium 4.

thanks for helping, I wish I'll find the solution before tomorow :-O

BTW
What is a projection matrix ??

something that maps the output of the virtual camera to the actual viewport, and eventually prepares the former for perspectivization. anyhow, does that virtools thing have any camera control - if so, use it and rotate the camera, preserving all other cam motion parameters.
 
Almost all of ATI's drivers support screen rotation as well. I'm not entirely sure if 3D acceleration works when the screen is rotated though (i think it should) but I do know that overlays won't work on the rotated screen.
 
Cool guys, you really help

I tried the Pivot pro and it rotate eveything but my render.
Know I'd like to the nView thing of nVidia but I can't find
any of those rotation settings in the nVidia stuff in control Panel
there are setting of multi sort but not this one.
Do you know how it work ????

PS- I can't just rotate the camera cuz I have tons of parameters
that take the vertical (particules/animation etc...)

Thanks again
 
A camera rotation is actually exactly what you need. Rotate it the same way as the projector is rotated.

Example:
If you have particles falling down and rotate the camera 90º clockwise, then the camera will see the particles falling "left to right". But if the projector is tilted the same way, then the projectors "left to right" is the viewers "down".


But another important thing:
What have happened to the aspect ratio?

I assume that you've created your content with 4:3 in mind (screen 4 units wide and 3 units high), will it be 3:4 now?

I don't have an NVIDIA card, but I believe you want the option "Display Orientation" which is in the "Additional Properties" section. Like this:

GREAT !!!

:)

Thanks to you all
I've set a rendering on a texture on a simple quad, at 1024*1024
resolution and it works great. I can even rotate it and do anykind
of movement as if I had a video editing console :)

Thank you again, It was just about pointing a solution and you
spare me 24 hours of exausting work.
