stereo rendering vertical parallax issue

xin.liao Member	Hi, I’m testing the stereo rendering output that p3d export, using the demo bike scene, I changed the stereo basis to 0.65 in order to view on a small screen, but the result was not good, the left and right views have vertical parallax, which leads to very un-comfortable view experience. Are you using a toeing method to generate the stereo images other than off-axis? Published on 25 April 2021 at 5 h 04 min
Kevin Member	Hello, Thanks for contacting us about this. Did you generate this image via the “snapshot panorama” feature ? Is the problem still there when using the default value of 0.065 ? Published on 26 April 2021 at 18 h 27 min
xin.liao Member	No, it’s not a panorama, just Stereoscopy in Convergent Mode. Using 0.065 basis still have such problem. Published on 27 April 2021 at 4 h 45 min
xin.liao Member	The parallel mode is correct in vertical parallax however missing the functionality to adjust the convergence plane, the convergent mode looks more like a toe-in mode, which rotate the camera around the center of the 3d model. Published on 27 April 2021 at 5 h 05 min
Kevin Member	I will ask the development team about this, to confirm if we are using the toe-in method or if it’s simply a bug in the code. If it’s the toe-in method, it is a method which has limitations and we will not be able to fix it quickly. Published on 3 May 2021 at 9 h 28 min
xin.liao Member	Hi Kevin, Any update on this issue? Published on 18 May 2021 at 4 h 06 min
Kevin Member	Hello Xin.liao, Our development team plans to check this at the end of the week. Sorry for the delay. Published on 18 May 2021 at 17 h 52 min
Kevin Member	I checked with the development team during today’s meeting and you are correct. Stereo rendering is currently using toe-in method in Patchwork 3D. We have another algorithm for stereo rendering which doesn’t use the toe-in method in one of the other software in Enterprise version. I can send you a trial licence for the Enterprise version to test this other algorithm if you are interested. Published on 20 May 2021 at 17 h 29 min
xin.liao Member	Fine, please send me an email, you can also contact me on Skype: shownstockman@gmail.com. I’d also like to try the vrpn feature on a mini size stereo power wall. Thanks! Published on 20 May 2021 at 17 h 48 min
xin.liao Member	Hi Kevin, Would you please send me the trial license you refered? Published on 24 May 2021 at 4 h 34 min
