Understanding Pan Z

[davegee]

The attached Photo Frame EXE is just an excercise in understanding better how the Pan Z function in 3D Parameters works.

Please forgive the "gaudy" colours - they are only there to prove that everything works as it should.

Now that I understand more about Pan Z the next version will be thinner and possibly have more bells and whistles.

I see it as a possible short Title Sequence and not as a means of displaying images for 30 minutes at a time!

wont run at my end

Sorry Ken,

Made in V7 Beta 9 - nothing taxing about it - no big images - no video.

Any error message?

I have downloaded it and run it on my aging Sony Laptop from the forum - no probs.

no error messages

- just stalls system - taskmon says it is not responding

v7 b9 installed on mine as well

Hi Ken,

It runs fine for me - not sure what the problem could be...

I created a quick PanZ demo - try it and see if it runs on your system....

AND TRIED IT AGAIN IT WORKED OK

TRIED DAVE'S

[David Porter]

Worked fine for me and no problem with my AVG. Good demo too!

[davegee]

Ken,

Tried Lin's and did not get AVG warning. I'm up to date.

Lin,

We have all seen demo's of 3D objects where all sides are equal (cubes etc). My difficulty was grasping the relationship between objects where the sides are not equal (Corn Flakes Packets etc). I think I have it now. Having the cutout introduced new problems with "ordering" front to back.

You learn more from doing these things than examining other's efforts!

Dave,

No problems running it on my system. I gather that you hit the problem of "object stack order". Unfortunately, our intellect is greater than PTE's (no disrespect to Igor and his team). When doing X-axis or Y-axis transformations, we can look at objects moving in a 3D domain and work out that, at a particular point in time, Object A will disappear behind Object B because of their virtual displacement along the "Z-axis". PTE knows only their relative order in the object stack and will always show them in that order, irrespective of their virtual "Z-axis" displacements.

Peter

well boys the pict does not lie and i have not enough smarts to edit

i must have a setting different to you fellas -- when i get enough time i will try it on the new win 7 system

Hi Peter,

You will note that in my example, the stack order issue is solved by a work-around.

To accomplish this, you simply "match" the PZR and 3D transform settings with a second slide but reverse the stack order (layer position). By then using a "quick, no transition" setting between slides, the motion or animation is seamless and the observer is never conscious of the fact that the slide has changed. This way stack order becomes a moot issue when creating the animation....

Best regards,

Lin

Hi Dave,

Right! The solution to the ordering issue is to create a duplicate slide with the stack order reversed and use a "quick, no transition" setting between slides.

Absolutely, experimentation and practical application are, by far, the best "teachers."

Lin,

I learned that trick when doing my Rubik's Cube sequence. I also had to split some of the slides like that in order to resolve some issues surrounding "Show Front/Show Back". Ideally I would have liked the ability to change the "Show..." settings at a keyframe.

B)I changed my plans and downloaded both demos to the " WIN 7 COOLER"

BOTH RAN WITH NO PROBLEMS

avg db 1509/3651

marvelous colours on both shows tho i prefer Dave's - he gets the hats and jackets this time - sorry Lin - you have enough

ken

[Lin Evans]

Hi Peter,

It would be helpful if we could change layer position via keyframe, but not a huge issue, just a bit time consuming. Being able to copy and paste slides to the main list is a huge plus since the settings are also copied and only a quick Ctrl Pg Up or Ctrl Pg Dn is necessary to accomplish the mission.

Lin

Hey Ken,

LOL - dang, if I had known we were competing, I would have replaced the landscape with a naked lady and labeled the demo "R" rated - HA!

Hi Lin,

I know about that technique but didn't have to use it here.

There are two slides only and the quick transition is between the X axis 360 degree turn and the Y axis 360 degree turn. In other words:

NO TRICKERY!

Each 360 degree turn is carried out in its own slide without the need for re-ordering the objects.

DG

P.S. Everything you see in the demo can be done IN ONE SLIDE with keypoints needed only to change direction of spin etc.

However, when doing it all in one slide the "second" image would appear upside down.

[Lin Evans]

Hi Dave,

No trickery is good!! Whatever it takes to "get er done" is what's important. There are usually several ways to "skin the cat," and for me that's what makes PTE so interesting.

Ken,

I just uploaded this file to www.virustotal.com online service which can check files using several dozens of different antiviruses. It found nothing. Please re-download the file again. Probably your AVG antivirus settings have the highest level of sensitivity?

Apologies for delay. Here's the "thinner" Photo Frame.

I've used exploded views to show construction.

Thanks Lin,

I have been trying to get a grip on the mathematical relationship between the Pan Z control and the elements it is being applied to.

I now see that the Pan Z parameter is a function of the PARENT in a Parent Child group. It's 100% value refers to the Width or Height of the Parent be it a Frame or another Object and that's an important thing to know when the object that you are building is not a perfect cube and has transparency as in the case of a photo frame. It is also important to SIZE a frame when starting something like this rather than accept a frame which is the same resolution as the project.

Thanks for the renderings which you sent in the PM - I will look into that! It wasn't what I was really setting out to achieve but it is the next logical step if I continue with the project.
