Zoom/BlowUp Region?
Zoom/BlowUp Region?
One of the rendering modes Maxwell has is like Render Region, but instead of selecting a portion of the entire camera's field of view and only rendering that - with the rest of the image being blank - it zooms the camera in to the selected field and renders it at the same size.

As an example, if you had an image at 1440x900 pixels and defined a 400 pixel wide selection in the corner, it would render that at full-size as if the camera had been positioned there to begin with.
Would this be possible to implement?

Re: Zoom/BlowUp Region?
...about this, I started reading the rest of the maxwell help, and the "shift lens" chapter rang a bell in my head.
So, at the moment the shift lens feature in Indigo actually shifts the image up/down/left/right of a certain amount of space. In real photography, the shift lens feature allow to capture an image as if the geometry has vertical lines even if the vertical perspective is distorted (and so vertical lines converge).
I am sensitive with this kind of feature since I actually use certical lines in all my renders and at the moment I have to find a correct view in sketchup, while I could simply set a scene and then play with parameters in the indigo GUI.

Do you think you could explain how you use that feature? It sounds interestingPibuz wrote:...about this, I started reading the rest of the maxwell help, and the "shift lens" chapter rang a bell in my head.

I don't often change the camera's position in Indigo and have never used the shift values at all since I didn't know what they did, so I just assumed it was like Cinema 4D's cameras and that if you moved them it would change the field of view entirely, so focusing on a specific portion of the image would require creating a new camera and *carefully* matching it up, which took a lot of guesswork ^^;

The Film Offset X & Y Value of the C4D camera gets transfered to Indigo, give it a tryRezca wrote:Do you think you could explain how you use that feature? It sounds interesting

Yeah that's absolutely brilliant and also necessary for every architectural rendering!!!Zom-B wrote:The Film Offset X & Y Value of the C4D camera gets transfered to Indigo, give it a tryRezca wrote:Do you think you could explain how you use that feature? It sounds interesting

Actually the shift lens feature in indigo moves the lens.Pibuz wrote:...about this, I started reading the rest of the maxwell help, and the "shift lens" chapter rang a bell in my head.

Can u show me some images demonstrating the problem?
Re: Zoom/BlowUp Region?
Ok, here's what I mean. Note that english is not my native language so I might be wrong about the correct technical name.
The first image is what I think Indigo should be able to do, that is making perspective converging lines to be rendered vertical; the second and third image is what Indigo actually does at the moment: it keeps the perspective point and "tilts" the image up, down, left or right, but the converging lines keep on..converging

Re: Zoom/BlowUp Region?
Ha, last time I dabbled with the lens shift feature in Indigo I was expecting Indigo to do what Pibuz has shown in his first image, ie get the converging perspective lines to straighten up to vertical rather than converge, but I got exactly what Pibuz got in his images - it just seems to tilt the camera up or down and makes no difference to the perspective.
I just assumed I was using it wrong or I had my terminology confused and lens shifting was something else.
So, I am also interested in this feature.

Re: Zoom/BlowUp Region?
Just point the camera forwards, then put the shift to a positive value.
Re: Zoom/BlowUp Region?
Sorry Ono: what do you mean?
Re: Zoom/BlowUp Region?
To get an image like on the left side of 'how its supposed to work.jpg',
Point the camera directly forwards at eye level (e.g. no up component in forwards vector),
then set the shift to a positive value.

Re: Zoom/BlowUp Region?
That is exactly what I usually do
Re: Zoom/BlowUp Region?
And it works, right?Pibuz wrote:That is exactly what I usually do
Re: Zoom/BlowUp Region?
Well, it does, but basically I do the work, by setting z-aligned POV and vanishing point.
I'm no photography expert but I kinda have the feeling it's not exactly the same thing. But I may absolutely be wrong!

Re: Zoom/BlowUp Region?
Hi Pibuz, if you want that to happen you must have no torsion on the camera it can only rotate in one axis, then you have it like you want. I had a camera in cinema that did just that, you could only move it and rotate it in the y axis, it worked as a charm.Pibuz wrote:Ok, here's what I mean.
