Question

Is Ambient Occlusion accelerated in Creo 3.0?

I'm using Creo 3.0 M060 on Windows 7 with nvidia Quadro K4200 and in the options panel it says that for "Pro/Engineer (Creo Parametric)" ambient occlusion is "not supported by this applciation". While on PTC website I read that ambient occlusion is hardware accelerated.

Hi Paolo,

Can you clarify a little bit more?  What exactly are you doing, when you receive the "not supported by this application"  error?

Thanks,

Amit

Sure:

- Launch Creo Parametric 3.0

- Right click on the desktop, then select "nvidia control panel"

- In the settings tree, behind 3D settings, select "Manage 3D settings"

- Select the tab "Program Settings"

- There is a dropdown menu with supported applications found on the system, it's called "Select a program to customize"

- Select "PTC PRO/ENGINEER Wildfire (PTC Creo PArametric)

- Once the program is selected the interface shows a table with the settings for that program, first line is: "Ambinet Occlusion", it's grayed out and the "settings" field is "Not supported for this application"

I ask about the ambient occlusion because when it's enabled and the model is spinning, the effect is very grainy like a low resolution texture, and it "cleans up" when the model stop spinning.

If I remember correctly, the effect you describe is intentional. When manipulating the model with AO enabled, the effect is simplified to improve performance and when you settle on particular orientation it's back to full visualization. I think it was deliberately coded that way and probably has nothing to do with graphic drivers.
