scene origin coordinates

[cikho]

ok, this might be confusing, but..

is there a way to highlight scene origin 0,0,0?

i'm asking this, because i needed to create a shot, top view, isometric, of the same interior, but with different layouts, and these layouts are oin different files..

my ideas was to:

1. set the camera in a proper position in one file.

2. copy the camera properties tranformation (point of view and looking direction)

3. open the second file and creare a very same camera with the verysame settings.

actually it turns out that the two views are completely different 😐

this honestly does not make any sense to me, the base objects are the same, and in the same position..

any ideas?

Hi Cikho,

i don't know the native software or your files.. but showcase is consistent with the original reference system.

So if your layouts are all coherent with the origin 0,0,0  you can easily import each of them.

If they are not, can be a easy way rearrange your project and all layout in their native software, maybe in one file ?

If this will be too laborious, can you attach here a very simplified scene with what do you have and what you want to obtain finally?

Don't worry, it will be fix in some way.

[cikho]

the problem is not with the original models, i can switch from one to the other without any problem.. an element used in position x,y,z in scene A can be correctly imported in the same position in scene B, also, both the scene are built using the same reference.

the problem is the origin of the camera, or something like that..

it really confuses me..

[admaiora]

I don't understand where is the problem.

1- Have all the layouts files coherents with  0,0,0 in the native software.

2- Create a scene in showcase, import the first layout file, choose a view a save it in a shot > Render it

3- In the same previous scene hide the first layout in the organizer and import the second layout. Make current the previous shot > Render it

4- Same of point (3)

Sorry for my misunderstanding. If you can attach a sample pack it can be better.

i know that i can use that workaround, the problem is that i have 4 scenes and they're all huge..

probably using the compare scene tool could be the best option.

my problem is not a possible workaround, the actual reason why i posted this question is to understand how the cameras are managed..

why the same camera in the same "mathematical position" in two identical scene has a different output?

another question is, why in a top isometric view, the focal lenght of the camera has an impact? i mean, in an isometric view the lense should have non sense...

the thread is more about theory than finding a precise solution for my case 😛

[admaiora]

A scene zipped would help, it can be more that a thing.

Anyway, if the camera position is not the same...so the coordinates maybe are not the same mathematically speaking.

For example.

I have a scene and i have a very nice camera position and point of view.

This:

At this point, i presume as you did, i open a new scene a set Camera Position and Look at Position with the same coordinates.

X: -23  Y: -23   Z: 6

X: -1    Y: 6     Z=-4

Then i realize that the view is not the exactly the same.

But i can trust those coordinates? 

No, i can't.

The coordinate i have inserted are not the same of the previus scene.

So the original coordinates

X: -23  Y: -23   Z: 6

X: -1    Y: 6     Z=-4

are "exactly"  :

Pretty differents.

This can be  a reason, but without your files it is not easy to catch it.

I usually import similar scene with very very huge files, the organizer can helps  a lot.

-For the Isometric question. Showcase manage only perspective view, and not parallel view (as in Invenor, Autocad, etc). So the isometric view is actually an angles perspective view.

[cikho]

unfortunately i cannot post theese scenes as they depict things owned by the company i work for, i'm not sure if i can manage to replicate the issue in a sample scene.. i'll give it a try if i have time.

the differences you mention are too small to justify the difference i see..

basically i use the isometric top view, which is called by the view cube (actually the only way to call an isometric view, pretty bad 😐 ).

as you may know, the top view called through the cube is object dependent, so it zoomes as much as it's needed to have all the selected objects in sight.

once i do this i reposition the Z of the camera where i need it, in order to have the proper zoom and i save the shot.
i check the mathematical position in the camera properties windows, and copy them (to notepad).

save scene
open scene B.

select all, call top view through cube, check mathematical position, paste the previous value and..

boom, position x,y is correct, zoom is different.

even if the mathematical position is correct, both for the camera and the model, what i see is different in the two scenes..

of course, this doesn't make any sense to me..

p.s. - using the compare scene tool, with an additional external UI to call more than 2 files works for now, but, again, i see some strange thing happening to the software here 😛

[admaiora]

I am confused.

Do you use a "Isometric view" or a "Top view"?  With "Isometric Top View" i can't replicate exctly what you are verifing.

[cikho]

top parallel (orthogonal) view, simply press the "top" face of the view cube

[admaiora]

Ok.

Showcase as i said before use a perspective view, with the exception of the ortho view with the cube face, that set the view in a ortho view. (If you do a little orbit after you set a ortho view you will see the scene pass suddendly in a perspective mode)

A face cube view as you said is set on  the entire model space (unless you select something before).

So, this behavior may be the cause toghether with the focal length (that with the top view can affect only the Z camera position).

Look at this:

Top view -Focal Length: 150

Top view -Focal Length: 12

The change for Z Camera Position.

But if i change it to 186 and Apply...

Clicking again the cube top face, it allign correctly

So, just verify, same focal length, same positions, then click the cube top face.

[cikho]

focal length was the same i've checked already...

another strange thing happpens with the side views..
for example, i set a certain side view, with look at position in 0 and camera position at y= 300 cm.

at a certain point i decide i want the very same camera zoom, but looking from the other side.
so, easiest thing, go to camera properties and set y=-300

in every other software this works.. in showcase it doesn't, the zoom is completely different... 😐

i obtain the same zoom at y-150 or sort of, so it looks like the camera axis reference is different than the model axis reference (which of cours is positioned symettrical with respect to the Y axis) 😐

this is true only for the orthogonal views tho, for the perspectives, it looks like it works good 😐

i even more confused

hoenstly i don't understand why we don't have a camera grip in showcase.. it could be sooo beneficial 😐

[cikho]

here is an example with the car sample scene..

same numeric values, just the mirrored Y, but the view is not the same..

this is making me crazy 😐

[admaiora]

No problem for me.

[cikho]

these were perspectives, i used the ortho view of the view cube, as i told, in perspective works fine

[Christian_Garimberti]

I think ORTO view are not consistents....

But you can simulare orto view with very high focal lenght.

If you put 2000 in the focal lenght (the maximum) your image lokks like an orto view.

Maybe in this case your cameras looks the same.

[admaiora]

i agree with Christian. Passing to a ortho view you will renounce to some camera properties.

[cikho]

it's incredible how many small corrections this software needs, that, once done, could really make it better, requiring like 10 minutes of coding effort in total 😐
