Orthographic/Perspective Views in Paraview

Question

Problem: In Paraview 5.6.0, for an arbitrary geometry, the view directions can be set for the side, front, top views (shown below) by one-click.

However, the display of either an orthographic view or a perspective view (or any standard projected views) is not short-cut (e.g. bottom-left subfigure), unlike other software, e.g. ANSYS.

Attempts:

The side, front, top view directions can be set simply by clicking a Set view direction to button below if View->Toolbars->Camera Controls is on.

I explored Adjust Camera button, which gives the complete control on projection views. Nevertheless, it is difficult to adjust for a novice.

Is there any shortcut in Paraview to obtain a standard orthographic or perspective view?

PS: Google-search was fruitless to me as well. I also might completely miss the correct terminology for views.

If you wish to define additional views in Paraview, you can set Custom Viewpoints under Layout > Adjust Camera (small icon in layout view next to 2D/3D switch at the right).

Starting from -Z view, one can set the azimuth and elevation angles to obtain the following views (in accordance to SolidWorks standard views):

Isometric view:

Azumith = +45°
Elevation = +35.264°

Dimetric view:

Azumith = +20.43°
Elevation = +19.244°

Trimetric view:

Azumith = +27.368°
Elevation = +31.174°

For other user-defined views you can use the following equations to calculate the azimuth angle $\gamma$ and the elevation angle $\delta$ :

I'm just curious what book or article is the picture in your post? I'd be interested to learn more about this. – kensaii Jan 12 '22 at 16:00

I just added a reference to the book under the picture. – DaveD Jan 13 '22 at 17:55

There is no shortcut but adding one should not be a lot of work. Feel free to open an issue in our gitlab

However, if you've configured it once manually, you can save the viewpoint in the Adjust Camera dialog or using the viewpoints toolbar.

Also you will want to enable Camera Parallel Projection.

Thanks; but what is the reason that I may want to enable `Camera Parallel Projection`? – Herpes Free Engineer Jan 23 '19 at 14:54

Side, Front, and Top view require it to have a true orthographic projection. – Mathieu Westphal Jan 23 '19 at 17:01
In addition to @MathieuWestphal answer, axonometric views (such as isometric, dimetric or trimetric views) are only defined in terms of orthographic projection, i.e. for `Camera Parallel Projection`. – DaveD Jun 24 '20 at 16:35
