Isometric and Perspective

ZBrush Usage Questions
#1

I forgot how to switch from Isometric back to Perspective view.
Please, refresh my memory, as I can’t find the info in the forum
nor the manual.

Activate the gyro and then activate Draw>Perspective. In the PC version, perspective is only available when the gyro is active. It switches back to the isometric when you enter Edit mode. The Mac version allows perspective when editing the mesh, and this will be added to the PC version in the next free update.

Thank You Much!

when this free update will out???
perspective is very important while modeling…

thanks in advance.

A question, why the perspective function (Draw menu) is not working how it has to work? When I set the slider to zero or a low number, the perspective is overdone. In my opinion zero = no perspective and not a result like using a fisheyelens.
Doing something wrong?

Activating perspective tells ZBrush that you want perspective. So you will always get some, even with the lowest setting.

In my experience, Global Perspective is preferable to regular perspective. Simply Shift+Click on the perspective button to activate it. Then you can set the vanishing point by dragging the Distortion slider onto the canvas and releasing it where you want the vanishing point to be. This also has the advantage of allowing multiple objects to share the same vanishing point, which helps pull the scene together more effectively.

Aurick,

Saying that if the button is enabled Zbrush assmues you want perspective so there will always be some is all well and good, but the amount of perspective added is far too severe. As Bas commented, adding "perspective" to a camera view of a model is not equivelent to using a fisheye lens - anyone that has tried matching 3d models to a photograph will understand this. Having some distortion/ perspective when activated is easy to understand, but it should be the equivelent of a "1" setting on a slider that starts at zero - zero being isometric, not a "50". We need a more customizeable perspective mode (also while editing on PC ver.) that has finer ranges of adjustment and more real world / natural camera lens simulation.

The current “perspective” mode is more like a “forced perspective” illustration effect rather than a true “camera lens like” distortion. Sounds like we’re requesting a different feature altogether ?

Thanks,
Jay

i agree totally!

paralel modeling mode, is totally not-real and not-artistic.

perspective is much more natural in sculpting, simply because real world sculptures are made in perspective.(real world perspective of human eye - aprox. ~50mm lens equivalent of 35mm camera film.).

is almost inaceptable who (yet) zbrush have no persp. in modeling…

almost… because Zbrush is so fantastic in others aspects.

thanks

The Gyro Move seems not take the perspective in moving, you must retake the Gyro rotate for see pers in rotation :slight_smile:

I know all we ask is not easy in a program like ZB. We are playing in a kind of hybride 3d environment, and we play with ‘pixol-mountains’. I did some study with the gyro/perspective function and things can be done but not the easy way we are used in other 3d programs. It should be nice we could work with numbers while setting the vanish point. Shift-click somewhere does tell me nothing. I also need a point of view.
Moving the model backwards with the gyro changes the perspective. I like to make scenes with several objects so the use of perspctive gives a lot of problems.
Maybe a kind of ‘setup-room’ inside ZB where we place the objects and the lights could be an option?

#11

…help you Bas :wink:
Just ask it to the mad scripters :slight_smile:

I think it’s not easy to make, and after all I like more this kind of things build in the program itself.
But maybe you are right to see ZB just as a modeler and servant for other 3d programs.
I do not, because I like to work with it and I like the illustration-look and feeling of it. I also like to work with the pixols.

I just like to get the best out of ZBrush!

I didn’t know about changing the vanishing point, that’s pretty cool.

But the perspective view still isn’t what it could be, IMO.

#14

Thanks for the info with draging the slider to define a vanishing point.
I gave it a trial but I can’t see any changes or difference when I define new vanishingpoint (while in perspective mode - of course :wink: ). Can you give me a hint please?

You usually have to change mode before the change is active. After redropping the VP, switch between Draw and Move to force the change.

Unless it has changed (or I got it wrong), an important thing to remember is that the VP is not saved with a document. It is always best to place a marker object on it’s own layer so you know where the VP has been placed and can replace it if you are working over several sessions. Make sure to place the marker object at the correct zdepth.
