Camera

[AleAle5025]

Hi

PTE is an excellent program.
It's a pity that the camera is always on in the program.
The camera creates problems on some slides.
For example, shifting a slide away from the center causes it to be distorted.
I have to come up with something.
To make everything look as it was intended.

Sorry, but I don't understand.  What do you mean by "the camera is always on in the program?"

The camera does not turn off. It would be nice if it could be turned off.

what Camera?  PTE does not have a Camera

Do you mean the visibility of an Object?

Maybe I explained something wrong.. I made a butterfly to flutter through the photos.. As long as the butterfly is in the middle of the frame, everything is fine, it's worth moving to the edge. The butterfly does not flap its wings, but rolls from right to left.

I'm going to post a video now.

From the behavior of the butterfly, I thought there was a camera in the program

The correct butterfly movements are lost in the upper right corner. And he won't be able to fly correctly from the photos.

Трудно заставить бабочку двигаться должным образом. Вы можете увидеть, о чем я говорю, на фотографиях.

When you move something around the Frame, PTE automatically adjusts perspective.

You need to create Keyframes to make the movement do what you want.
You may need to make some 3D adjustments to the butterfly, but your video does work as it is.

Hi.
Thanks for the reply. There are dots on the slide. And I have different modifier settings.
So that the butterfly flies more or less normally.

PTE renders everything with the fixed center of projection at the point with the coordinates X=Y=0, Z=-346.4 (sqrt(3) x height of the screen). It gives us the perspective of a lens with a focal length of about 40mm. It isn't that difficult to emulate a change of this focal length as you can see from the attached example whose construction I learned from Jean-Cyprien.

very interesting to know this, thanks jt49

Thanks for the file. I put all the numbers in a container. And I moved the container to one edge of the slide, then to the other edge.
Look at the distortion of the numbers. Now you see the problem with the butterfly movement.

2.rar2.rarThis problem often occurs with round frames.

Из-за визуального искажения. Угол обзора меняется, и мы видим крылья (цифры) разных форм и размеров. По сравнению с цифрами в центре слайда

For the butterfly you may use my model to render it at a (very) long focal length (160mm or even more).  I would guess that your distortion problem will become less pronounced. On the other hand, we are in 3D, and the distortion is a quite natural effect, isn't it?

Thank you. I'll use these settings somewhere.
The problem is not in the points and amplitude of the oscillations. The problem is in the container.
If you transfer each file separately, it will take a very long time to assemble the slide. I don't think anyone would do that in a complicated slideshow. I usually put everything in one container, then copy it and assemble the slide.
A long time ago, I assembled a butterfly in Adobe After Effects.
Thanks for the help and advice.

ВIn the container, the file is visually distorted when moving from the center of the slide to the edge. As shown by the numbers in the photo. If you move one file. Then everything will fall into place perfectly. And it will work well.

[AleAle5025]

Experiment.
I deleted all my settings, and what happened? The butterfly flaps its wings well only in the center.
Something incomprehensible is happening from the edges of the slide.

Hi,

If I understand correctly, the fault is the desynchronization of the wings on the left and right?
In this case I think it is the positioning of the key frames which is at issue, the key frames of the wings on the left are not corresponding to those of the wings on the right. I don't think it's a PTE problem.

Hi,

 

If you change the "pseudo" focal lens, I think you can obtain what you want.

No, the program is working fine. Now I'm going to try to figure out the butterfly. With various fixes from scratch.

When moving the file to the upper right corner or to the left. The viewing angle of the file changes, and the visibility of the file changes at an angle. to remove this effect, you can use containers, as Denis showed 
Zoom (Focal)=10. That's what I used. Thank you.
I put an oscillation modifier on the wings to make it easier to change the oscillation frequency by points. Your modifier is a bit complicated. It's difficult to work with him in style.

On the second slide, I used containers similar to the ones Dennis had. Everything works fine.
There is one container on the first slide.

You can ignore such a shift, as can be seen in the pictures. But it is there. Everything works correctly with the additional container in the second slide.

The X-size fits perfectly zero. And the wings are working properly.

Zoom (Focal)=0.

[denisb]

Hi,

It work fine.

0 is equivalent to an infinite focal lens.

Hi.
We have found a good solution together.
Good luck in further developing an excellent program.

[jt49]

Denis' method for the change of focal length really works well, and it is easier to handle than the method I mentioned above. Both methods are more or less equivalent, but when programming a dolly zoom, Denis' method gives a better result.
