Strange aliasing with 3D plot appearance

  • April 27, 2023

My 3D plots have started appearing like this:

When I drag the plot area, the problem disappears:

But as soon as I let it go, the weird pattern reappears.

 

I thought it might be a problem with the mesh frequency pairing with the pixel spacing on my display, but resizing does nothing, and, in fact, the problem appears as soon as I open a new 3D plot area.  

Anyone encountered this?  More pertinent question: does anyone have a solution?

Working in Prime 8.0.0.0

 

Thanks for any hints.

Richard

Hi,

We have a bit to do.

Right click on an empty part of the desktop and you should get a menu like this.

Using this menu twice.

First time select the NVideo control panel

In this control panel on the left is 3D settings.

In the Manage 3D Settings do three things

Set the preferred graphics processor to "auto select"

Press the restore button in lower right hand corner.

Press the restore defaults menu item in top right corner.

Close the window

Right click again on display blank area

This time select the item graphics properties

A dialog box for the intel graphics is displayed

Select 3D

A dialog box will open with the 3D settings

In the middle bottom is a restore defaults button use it

In bottom right is an apply button use it.

Close the window.

Now try Prime again.

If Prime does not work after this restore to defaults you will need to experiment with anti-aliasing options in oneor both graphic processors remembering you can force selection of a specific processor in the Nvidea 3d settings.

Good luck Terry

Hi,

Can the worksheet be uploaded?

 

What version of windows are you using?

What is the graphics card?

 

Cheers

Terry

Sure.  But it's as simple as: open a new worksheet; insert 3D plot.  Then plot whatever function you feel like displaying.  You can even skip the "plot whatever function you feel like displaying" and the problem still exists, as you can see in the screenshot below.

Graphics card?  I don't know.  On my device manager I see Intel UHD Graphics and NVIDIA RTX A2000 8GB Laptop GPU.  Does that answer your question?

Must be a video card issue...OR, it's a Prime 8 issue...my screen image here is from Prime 9 - looks normal.
