Blinking screen in 3D mode

[slavas62]

In the latest version 1.27 in 3D mode, changing the coordinates of the point vector object (feature.getGeometry().setCoordinates([...]) or layer.getSource().addFeature(feature)) causes the entire screen to blink. How it can be fixed.
In 2D mode all ok.

Thanks in advance.

Thanks for reporting this @slavas62. Is it also blinking in 1.26?
The only changes from OL-Cesium 1.26 to 1.27 are the update of the dependencies.

[slavas62]

In version 1.26 all ok.

I tested version 1.26 with the vector example. I can see this blinking when clicking the "add/remove one vector layer" and "add/remove one feature" buttons.
It does not blink every time. I will not have time to dig into this, please let me know if you find something.

[slavas62]

Well, if anything I find a message.

Just to add to this, see referenced issue #477

FYI, there is a chance this blinking was a Cesium issue which we just fixed in CesiumGS/cesium#5632

It will be part of Cesium 1.36 on August 1st.

Thank you @mramato, I confirm Cesium master fixes the blinking of the OL-Cesium vectors example.

To everyone: next month version of OL-Cesium will be tested against Cesium 1.36. If you need an updated Cesium in the meanwhile you can simply compile it.

Everything works correctly. Thank you all. -- С уважением,Вячеслав Серебряков   03.08.2017, 15:25, "gberaudo" <[email protected]>:Closed #465 via #481.—You are receiving this because you modified the open/close state.Reply to this email directly, view it on GitHub, or mute the thread.

Ok, so this issue has been fixed, however the runtime performance is terrible. Run it in 2d mode and everything renders quick and snappy, switch to 3d and everything drops through the floor ???

@HeavenlyHost, the solution was to update Cesium: there is no change in OL-Cesium code. You may have find a performance regression.
