Rendering issues with real-time simulation. #264

Closed hpmachining closed 5 years ago

hpmachining commented 6 years ago

Rendering looks correct when using "Run", but incorrect when using "Play" button. It is worse the faster you run the simulation. Also, the renderings don't repeat when simulated multiple times (using "Play"). I get similar quality, but deviations differ.

Run run

Play 1x play_1x

Play 1x - 2nd example play_1x 2

Play 4x play_4x

Yes, I was aware of this. Thanks for opening an issue for it though. When "Play" is active CAMotics attempts to simulate as the tool moves but the simulation cannot keep up unless the simulation is very simple or the movement slowed way down. So it attempts to simulate only the area of the workpiece that has changed since the last simulation was run. Unfortunately, it doesn't always run these localized simulations correctly. I believe the problem is due to incorrectly calculating the area that needs to be restimulated. This feature is a work in progress.

Thank you for the information. I thought it had something to do with not keeping up. I understand that it is a work in progress. Thank you for all you have done with this project. I have been studying the code and hope to learn how you do the simulations, but for now I'm just playing around with the UI. See my fork if you are interested in anything I have done.

Awesome, I merged all of your changes. You may want to resync your fork.

Fixed in new v1.2.0 release.
