Hi Everyone!
So im curious what im actually looking at when the perspective button is pressed? So when a model is printed will it reflect the model when the perspective button is pressed?
thanks for the feed back!
The perspective button gives a view of the model that is similar to what you would see if the object was in the real world. If you turn perspective off the view you get is without any distortion, so that parts of the model that are far way are in the same proportions as parts that are close to you. The DemoRhino shows this effect well - load it up and position so the head is nearer to but you can also see the tail, then try turning perspective on and off.
When perspective is on, the model itself is not changed, just the view on screen. So it doesn’t affect how the model is exported but it does give a rough idea of how your model would look if you printed it out.
It’s basically the field of view angle to match real world physics, e.g., cameras, eyes.
Some sculptors sculpt with perspective on and other with perspective off. Some sculptors can view (in their mind) what the perspective will look like even with it turned off (non-perspective view is called orthographic).
I do a lot of printing and I work almost exclusively without perspective. However I work with large sizes in zbrush and so the perspective Zbrush is extremely finicky and too extreme. This makes it mostly worthless for my work and it’s more work to dial into the correct perspective settings from model to model than what it’s worth.
It’s mostly a preference thing and if your mind can adjust what it sees on screen transferred into the physical print. Also with 3D printing sometimes you need to exaggerate details to get them to show up in the print. It takes some getting used to as the extreme detailing can look odd on screen, especially if you’re also doing renderings with your model.
So it’s mostly just a personal preference. If you’re getting good results without it then it’s not a big deal, but it’s important to understand that rendering and real world cameras use perspective views. I’ve also seen some beginner sculptors try to match a photograph with their perspective turned off and their model looks ‘off’ and they aren’t sure why. It’s a small thing that can make a big difference. Practice with both and use what works, sometimes you need it and sometimes you don’t.
I was just having this discussion with someone. My argument is that if you get used to seeing the model in a certain perspective, once printed the ‘angle of view’ might not be the same as what your eyes see.
So my question is…Does the slider setting in ‘Angle of View’ match any known settings like a camera lense (35mm for example)?
I have yet to find a definitive answer on this on. I was once told that a setting of 35-55 would most likely match what eyes see. Not sure if that is the case.
Like MentalFrog I work with it off. Mostly for the above reason, but also because when doing an action that goes through the model like a slice circle, the action isn’t symmetrical because of the angle applied to the model.
If anyone has an answer on the slider setting I’m all ears!!
