https://bugs.documentfoundation.org/show_bug.cgi?id=143465 --- Comment #7 from Kadet --- Created attachment 173806 --> https://bugs.documentfoundation.org/attachment.cgi?id=173806&action=edit Corrected text document I apologize. I was informed that an error was made in the example with connecting to an external library. Fixed the error. Added the ability to rotate the scene. The rotation also behaves inadequately. After turning by + / -70 degrees, the figure turns inside out and turns upside down. After +/-290 degrees, everything is restored. The 3D transformation matrix is set to offset by default (units along the diagonal of the matrix). I tried to convert it to the form for rotation on the Y axis. This did not lead to success. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=143465 --- Comment #6 from Kadet --- Unfortunately, I have been working in c++ for a very long time and now I do not have the proper skills to participate in the development of LO. Some part of the macro library for 3D is already in the attached file, but I'm not sure if it can be useful to anyone. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=143465 --- Comment #5 from Regina Henschel --- This is not a bug report but an enhancement request. Please change the second 'Importance' field and the 'Summary' accordingly. Unless someone pays a developer or there is a new volunteer developer interested in 3D, it is very unlikely, that development on 3D happens in the foreseeable future. If you have some knowledge in C++, you are invited to help us improving the 3D feature. If you want to work frequently with macros on 3D-objects, then I recommend to generate your own 3D macro library (and hopefully share it). You can get help in that on mailing list or forum. This might sound harsh, but it is a realistic view on the 3D feature. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=143465 --- Comment #4 from Kadet --- Thank you, Regina Henschel! Yes, of course. You can position models using the D3DTransformMatrix recalculation. You can even create these models using Shape3DPolygonObject, as well as a Cube and a Sphere too. But this also complicates the procedure for programming 3D scenes by an order of magnitude. I think that if a simplified programming model has been created, rendered as a separate structural object, then it is desirable to offer convenient ways to work with it, as is done in the Shape3DCubeObject and Shape3DSphereObject models. That's why I brought this issue out as a bug. And I ask the developers to further consider the possibility of providing simplified management of 3D models in 3D scenes. I would like to have convenient methods of positioning (D3DPosition) and size control (D3Dsize) in models like Shape3DLatheObject and Shape3DExtrudeObject. And in models of the Shape3DLatheObject type, you still have a convenient tool for controlling the rotation axis. In particular, I would like to be able to rotate the Shape3DLatheObject of the model along all coordinate axes, and also with the ability to control the tilt angles. How all this is very conveniently implemented in models of the Shape3DCubeObject or Shape3DSphereObject type. I will be very grateful to the developers for this. And I think it's not just me. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

https://bugs.documentfoundation.org/show_bug.cgi?id=143465 Regina Henschel changed: What|Removed |Added CC||rb.hensc...@t-online.de --- Comment #3 from Regina Henschel --- The 3D-Lathe object and the 3d-Rotation object are defined by a 2D-path, which may be open. This geometry is always placed on the XY coordinate plan. The 3D-Lathe object gets it third dimension by extruding in positive z-direction, 3D-Rotation object by rotating around the y-axis. To give the objects a different position or direction, you have to use it's D3DTransformMatrix. BTW, I find it easier to define a 3D Scene directly in the file text, then by macros. See for example https://wiki.documentfoundation.org/Documentation/HowTo/Draw/Make_a_3D_Star. One problem with the API is, that it does not provide a method for updating the rendering without distortion. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs

After introducing an object of the Shape3DLatheObject type into the scenes, the entire scene stops turning, although it was spinning perfectly before. -- You are receiving this mail because: You are the assignee for the bug.___ Libreoffice-bugs mailing list Libreoffice-bugs@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/libreoffice-bugs
