3D Surface plot Zoom/Rotate issues
3D Surface plot Zoom/Rotate issues
Hi,
There are issues with Zoom/Rotate interactions with 3D Surface plots. Essentially the mesh distorts or breaks apart and eventually asserts .
The code we are using worked fine with the 2011 DotNet version ( and we have tested on more than one machine with different graphics cards)
Version tested: TeeChartNET2018_4.1.2018.05040
I have created a simple bi-variate normal distribution curve to demonstrate the problem (our actual data/code is obviously more complex).
A screenshot is included to demonstrate the actual data.
- In this example I use a rotate tool and set the Chart-3D-3D % to 60% (through the editor)
- Normally we use left mouse button down to start a rotation. Here I am using right button in order to separate effect of rotate vs zoom action. Rotate by itself is fine, stretching the mesh with Zoom area selection followed by rotate appears to cause the problems.
Steps to reproduce
1. Perform a series of zoom (in) and rotate about the distribution shape.
2. Eventually either the Mesh will splinter with vertices drawn (far) into or out of the elevation axis (as though very large or negative values) or the plot will disappear and assert with an overflow error ( leaving the red checked box of doom)
Please note it is not easy to describe the exact zoom/rotate steps required.
Choose a zoom rectangle much larger in one dimension than the other , rotate 45 degrees and repeat is usually enough to trigger the assert
Code snippet follows
=========================
Steema.TeeChart.Styles.Surface surfaceSeries1;
Steema.TeeChart.TChart _chart = chart.Chart();
chart.Chart().Aspect.View3D = true;
chart.Chart().Aspect.Orthogonal = false;

Re: 3D Surface plot Zoom/Rotate issues
Hello!
thank you for your detailed report which I have added to our issue-tracking software with id=2093. Unfortunately I have not been able to reproduce the issue here, but I think I have a fairly clear idea as to the cause and as such have made a modification to the source-code. Could I please ask you to download this new build with the possible fix in it from here and let me know if it solves the issue for you?

Re: 3D Surface plot Zoom/Rotate issues
Hi,
Sorry for the delay as I have been experiencing issues (on my side) updating my actual code to test the new dll.
I have tested the evaluation dll on the sample code in my previous post.
There is a clear improvement (with 4.2018.9.25) in successive zoom and rotate rendering of the mesh.
I am unable to re-create the mesh tearing (found in 4.1.2018.5046)
However I am still able to generate the overflow error.
I have also tested our actual application with real data (see the screenshot in last post) and both the Mesh tearing and overflow error still exist ( to a lesser extent).
I am using a gridband, slice line, fast line and rotate tools ( something is still asking for version 4.1.2018.5046) when I display my plot ( I can find no trace of a version reference in my project, license etc)
many thanks
Mark

Re: 3D Surface plot Zoom/Rotate issues
Yes, this is a non-official build with the evaluation banner hard-coded in.
This could be because your license.licx file contains the version number of the TeeChart.dll - you can remove that section of it and it should work.
Excellent.
Okay - could you please paste the stacktrace here so I can see where in the code it's being thrown?

Re: 3D Surface plot Zoom/Rotate issues
Hi,
Yes I have tried deleting the license file contents and additional version information entries in my VS project files.
I run my application I see the evaluation banner on the 2D plot which leads me to conclude I have built with the evaluation version.
I display the 3D surface plot and a failed to read the assembly 4.1.2018.5046 but I can continue and the 3D plot is displayed
I perform a series of zoom/rotate actions as before ( there is tear up and the asset appears)

Re: 3D Surface plot Zoom/Rotate issues
Hello!
The licenses.licx file can be made version-independent by making sure the contents only contain the following:
With respect to the exception, I'm afraid I'm going to have to ask you to try and identify the precise circumstances in which it is thrown in order that I can reproduce the issue here. I think the best way to achieve this is to identify the Rotation and Elevation at which the code you sent throws the exception, and this can be done by tracking these values at debug time with code such as the following:
In this way you can manipulate the chart until the error is thrown and then read these two values - adding these two values (or values very close to them) back into the InitializeChart() code should be able to directly reproduce the issue.

Re: 3D Surface plot Zoom/Rotate issues
Hello,
many thanks for this. I've fed the last values of elevation and rotation (276, 16) before the error was thrown into the latest version of TeeChart.dll and still I can't get the Chart to throw the error. Neither is an error thrown for (elevation:280, rotation:345) or any values near these. Please find here the solution I used - if you were to download this project, do a "Restore NuGet packages" and run it you can see what I mean. Are you able to reproduce your problem using this project? If so, which values of elevation and rotation are reported just before the error is thrown?

Re: 3D Surface plot Zoom/Rotate issues
Hi,
I appreciate that the intermittent nature of the problem makes it hard to reproduce and we may have to reach an impasse.
I cannot reproduce the problem by entering the elevation and rotation value that caused a previous error to be thrown.
I can however make your demo app throw the error by repeatedly zooming and rotating (sometimes it requires a dozen or more steps).
Note - The only change I have made to your project is to change the target framework to (.NET 4.71 to match ours ) I appreciate the TeeChart Dll is built on 4.62.
Thank you for all your efforts to track this

Re: 3D Surface plot Zoom/Rotate issues
Hi,
I'm very sorry, but I am still unable to reproduce this here. It really is most frustrating not being able to solve this one for you at this time. I've spent a good hour zooming and rotating the chart, and have had another good look at the source code, but have not been able to reproduce the issue nor produce an idea of how it might be happening. My apologies. If you are ever able to reproduce this issue using a particular set of values for elevation/rotation/zoom do please let me know.
