Analyze points look out of place.

[Hugh.Venables]

Still using V8.1.1 . When using Analyze, Between Points, the white point that appears usually doesn't appear on top of the geometry being analyzed. The answers are right, so it's just a graphics thing but it's annoying. The visual error is sometimes worse than others. Any ideas?

Thanks Hugh.

Try the latest drivers for your Video Card, try slowing down the acceleration on the card.

Have you searched previous threads about vidoe cards? Take alook back in the emcam database, you might find the answer!

Definitely an OpenGL problem. Screen, Configure, Screen, Enable OpenGL® drawing.

 

Disable that option!

[Hugh.Venables]

Sensational Dave. That looks much better. What is the OpenGL® drawing option for? Thanks so much, Hugh.

[Allan Brown]

All shading/rendering of surfaces in Mastercam is done through OpenGL. OpenGL is a graphics application programming interface (API) used for 2D and 3D geometry and graphics applications.

 

That option tells the system either to use the same mode for Wireframe, or to use Mastercam's own graphics. When you see selection points that vary slightly, I believe you are seeing a mismatch arising from a combination of the two methods on a card that is perhaps weak on OpenGL, whether hardware, or drivers.

Thanks Dave. I presume the problem only exists with some video cards.

Cheerio, Hugh.
