High-resolution output file doesn't save perspective set with PeasyCam.

Utor

Hello,

I'm using and tweaking the code from a sketch that uses 3 images to produce a 3D scene (Three Phase 3D Scanner).

The original code already had a screenshot option but I needed high-resolution outputs and tried to combine some code from this link alexanno.net/2010/06/high-resolution-output-from-processing-processing-in-hd/.

When I press the "s" key it creates two screenshots: one normal and another with high-resolution. The problem is that the high-resolution image doesn't save the image with the perspective I chose with PeasyCam and makes an image with the initial perspective, while the standard screenshot works perfectly with PeasyCam and saves with the perspective I chose before pressing "s".

Can someone help me?

The sketch has 4 files: ThreePhase.pde, Controls.pde, PhaseWrap.pde and PhaseUnwrap.pde I think the problem is in the code of the first one: (I'm sorry for the long code...)

I don't think we can beginRecord() something that has already been drawn in the past! :-&

Thanks for the answer, what you say makes sense. I'm a newbie in this and don't know much about coding...

So what makes sense to me is to call void draw () { somewhere in the middle of the last piece of code... after the beginRecord(hires); and before endRecord();. I've tried it and I get "unexpected token: void". I guess I can't call a "void" within another "void". :-L

How could this be done?

Is there a way I can delete this last post?

I guess I can't call a "void" within another "void".

Java's reserved keyword void is solely used to define a method that doesn't return anything!
We don't call methods prefixing it w/ anything! Otherwise we'd call most of them this way:

void frameRate(60);
void stroke(255);
void strokeWeight(1);

How could this be done?

I believe that would be the same way how we save PDFs w/ beginRecord().
