satguru Posted January 14, 2018 Share Posted January 14, 2018 @jerome I am checking out the examples at https://doc.babylonjs.com/extensions/dynamic_terrain most of them are unresponsive/low fsp see this first example from that doc https://www.babylonjs-playground.com/#FJNR5#162 Quote Link to comment Share on other sites More sharing options...
satguru Posted January 14, 2018 Author Share Posted January 14, 2018 I suspect something to do with arcrotate camera ? There is a delay between start of mouse move and the camera movement. Once the camera starts moving the scene is responsive. The moment I stop moving the mouse and then start moving it again there is a big lag before the camera starts moving again The lag is more on chrome less on firefox Quote Link to comment Share on other sites More sharing options...
jerome Posted January 14, 2018 Share Posted January 14, 2018 well, this is strange because this lag didn't exist initially and the extension wasn't modified for ages... I have no idea why it behaves that way now. As you say, mabe something changed with the arcrotate camera behavior since This demo still runs and also became a bit laggy on my computer compared to the original release : http://jerome.bousquie.fr/BJS/demos/flightSim.html especially in chrome what used to be the fastest and the smoothest browser of my Linux. Since the v63 release, I noticed that things started to went wrong. No idea whether it's the reason though. I will have to investigate this and profile accurately.

satguru Posted January 14, 2018 Author Share Posted January 14, 2018 @jerome issue with BABYLON.MeshBuilder.CreateRibbon ? this example without CreateRibbon works fine https://www.babylonjs-playground.com/#FJNR5#208 Quote Link to comment Share on other sites More sharing options...
JackFalcon Posted January 14, 2018 Share Posted January 14, 2018 ... with no error in console. Weird. @jerome, Oh look createRibbon, interesting. And those are really great noise patterns... Quote Link to comment Share on other sites More sharing options...
JackFalcon Posted January 14, 2018 Share Posted January 14, 2018 and multiple-noise patterns in the future ----> Quote Link to comment Share on other sites More sharing options...
jerome Posted January 14, 2018 Share Posted January 14, 2018 didn't notice there was a ribbon also in the scene ... (btw, the dynamic terrain itself is ribbon-based) Quote Link to comment Share on other sites More sharing options...
