The artifacts when rotating

[Andrey Zimin]

When rotating any object see strange bevels (see photos)! In treejs I is corrected by adding

new THREE.WebGLRenderer({ antialias: true, logarithmicDepthBuffer: true })

How make is here?

Hi AZ.  Very strange issue.  I have never seen before.

http://doc.babylonjs.com/classes/3.1/engine

(antiAlias is third param)  Dunno about depth/alpha, sorry.  Others may reply soon.

Can you create a playground demo that shows problem?  That would help.

Also, please tell your operating system, computer-type, browser-type.   thx.

hi

try start make this

https://www.babylonjs-playground.com/#1JUXK5#84

have a lot of bug for now 

[Wingnut]

hahah!  Coool, Naz!

But I think you mis-understand.

I think @Andrey Zimin wants to STOP doing that.

I think Andrey's mesh NOW have bad rendering.

Perhaps he wants it fixed.  Not sure, but I think true.

How make is here?  (How can I correct it here, in BJS?)

Not sure... but think user wants it stopped.  We should ask before you do more work, Naz.

(Your playground IS really cool, though.  You are a friggin' genius!)

Thank you!) Sorry! For my bad english!

I think what we have here is an "action shot" of the screen, so the ghosting of the edges is actually the result of a slow "exposure" as he rotates the object (notice the "two" mouse cursors in the second image).

So, what we're dealing with here is an apparent "break" in the edge of the object as it's being rotated. My money is on a v-sync issue, but a quick search of the Babylon docs doesn't reveal any options for that. Am I missing something? I think there's a larger issue here, though, since ThreeJS is exhibiting the same problem. Andrey, it might be something specific to your system configuration or graphics driver; perhaps something to do with your browser settings, for that matter.

Yes, most likely it is! When I record video from the screen, the artifact disappears and on the record it is not! And ONLY CHROME)) Thanks!!!

A quick Google search revealed that someone else had the same problem in Chrome, and it turned out that his "Use hardware acceleration" option was turned off. Maybe you're in software rendering mode? Does Babylon even work in that environment? I don't know, but it's worth a check. Open up your Chrome settings, go to the bottom and select "Advanced", and you should see an option for that in there. You'll need to restart Chrome after you change it.
