Hi there,

I am new to using KD-3D and I am currently following the tutorials to increase my knowledge of using this beautify piece of software. However I am posting as I have a question I wish to ask. I am hoping to start making a short animated movie within the next couple of months. I would also like to make this a 3D movie like you get at the cinema either encoding it as an analglyph or stereoscopic video.

I have the additional software to do this however it requires a left and right video file to encode it into a meshed single video file. Does KD-3D have the capability of rendering a sequence into a 3D movie file or can you add an extra camera and render the output of this camera as either the left or right channel.

Any help would be great,

Thanks

This is doable with a second camera:

* Start a new document.
* With a viewport highlighted, choose Layout > Split Panel Vertically
* Choose "Create Camera" in the dialog that appears.
* OK the dialog.

At this point, you'll have two viewports side-by-side, connected to two cameras. The camera on the right is in a default position (looking towards the origin along the Z axis). What we want is for the second camera to maintain a constant offset from the first:

* Choose Create > Matrix > MatrixPosition
* In the properties for the new MatrixPosition, choose Input Matrix > Connect to ... > Camera > Output Matrix.
* Set the X property to 1m. This is how we'll control "eye distance".
* Select "Camera 2" in the Node List Panel.
* Choose Input Matrix > Connect to ... > MatrixPosition > Output Matrix

At this point, the right viewport updates, and displays the scene, offset from the left viewport. As you navigate in the left viewport, the right viewport updates to match. Bug: if you try to navigate in the right viewport, bad things happen ;) However, you can use Edit > Undo to get things back to normal. Also, you can go back to MatrixPosition at any time to adjust the eye distance.

Then, it's just a matter of rendering the scene from each viewport.

Cheers,
Tim

Hi Tim,

Thanks for replying, I shall try this and see how it goes. When I have a go at this I will have a look into the rendering of the two view points and post any findings that I make here.

Thanks again
Jonny

Ah, OK. I like these matrix. These must be helpful many times for animation. Thanks for the notice about it.

Hi,
I've a proposal to (maybe easily) fix the bug posed by Tim: could an option be added to 'lock' a viewport from changing camera position/direction?

Yep, that's a good way to solve it. The whole viewport system could use a thorough redesign, but just adding a locking flag would be easy. Did you just coin it as a suggestion, or would you also like to use this soon?

Cheers,

Bart

I haven't done much in K-3D recently, nor will I find much time to do so shortly, so it was just a coin mostly.

However, I use to keep one camera & viewport for the final shots ('picture'), changing position and rotation with the translation /rotation settings. This one I would like to lock. Then I use another camera & viewport to work from, moving around with my camera all the way.

But i'm not at all in a hurry. If there's any new release coming which doesn't redesign the viewport, it might be useful to add.
