Orthographic View Mode In The Viewer

Hi guys,

Love your platform! Good job :slight_smile:

Can you please add an option in the viewer that lets us change the camera mode to Orthographic?

Thank you

Hi @dutzi,
don’t you seen the camera parameters in the “scene” panel of the 3D editor ? there are a “field of view” parameter that you can set to 1°. I believe that it’s the actual “orthographic mode”

Hi @YannickDeharo,
Yes, I’m aware of that but there isn’t one in the Viewer, meaning you can’t see other people’s work in Ortho view.

Okay, I see what you mean.
What could be the advantage to see an object in Orthographic mode if it’s not the willingness of its author ?

I think it just gives an unique look to certain models, especially photogrammetry scans of rooms, architecture etc.

It’s better to have more options.

Why not…

Personally, I’m afraid that too much options on the viewer could lost the inexperienced visitor. When I show my work, sometimes, people says “Too bad we cannot see the wireframe!”, or “Have you another version without textures?” for example. Even when they already opened the “model inspector”, they often closed it immediately without really read it , too many things inside, too technical, they thought that wasn’t here.

Too much options could be a bad option too.

So it is necessary to carefully choose the features to offer to visitors. On my side, for example, I already wonder about the importance of displaying the “vertex normals”. If there is a relevant reason, I don’t know it (Maybe you could explain it to me).

But we could imagine to permit experienced users to access this feature without a viewer button. For now, to add “?preload=1” at the end of the scene address prevent the mesh to be displayed before the complete loading of its maps. We could imagine to add a “?fieldofview=1” at the end of the adress to change the percent of the perspective ?

We could also imagine a shortcut ?..

What do you say about that, @james ?

Indeed it’s difficult to balance offering lots of features to users while keeping the UI clean and understandable. Displaying vertex normals is important for inspecting models, especially before purchasing something in the Store.

You can already set FOV using the Viewer API. A URL parameter could make sense, but I really don’t know how often it would be used. I suspect most artists leave the FOV at the default 45°, some use 1° for orthographic purposes, and maybe a small number of other values for unique needs.


Thank you for your answer !

One advantage of seeing an object in orthographic view is taking away the perspective distortion (where things in the distance appear smaller). Orthographic view allows a viewer to see planes of an object align into the distance without distortion. This is extremely helpful when an artist is using the object as a reference to model or sculpt their own object for practice or professional reasons.

If keeping the user interface clean is the intention, an advanced feature button could be added to the model inspector to allow such useful flexibility to more advanced users.

Hi @blenderartist18, when I asked that question, I imagined precisely that reason. For me it can permit someone to copy your content more easily too. No ? To create blueprints without any difficulty. Especially for minimalist arts. I’m not sure it’s really a good point…

I see your reason, from a business point of view, but in artistic point of view copying is not bad. it is the desired learning method. half of sketch fab is educational already. I think its wonderful and i wish it could be handled with less business in mind but i’m naive.

you say to create blueprints without difficulty but maybe it is worth thinking about the opportunity, of becoming a live blueprint site and next time when ill want to model a Ferrari ill come here instead of blueprints sites. maybe it can be added as an account feature that you need to pay for small amount,I would go for that as a 3d artist for such a good database :wink:

Hi @blenderartist18 !

I can understand that but your exemple is different than mine. The Ferrari is such an hard exercise to model, even with the right blueprints ! But for artist who did minimalist art, cartoony art, when the force is the concept simplicity…

That will be mainly very easy for someone to copy and to sell some prints of it. No ? If I was that artist, I wouldn’t want to publish my work on Sketchfab for this reason. So If a lot of people think as me, that could be not wishable for Sketchfab popularity.

But, that might be cool if this option was optional as the one which permit to show the textures. The decision would remain the uploader’s one.
