CADSys4 3D.

[mdadali]

Hello,

Piero has released the source code for the 3D version of CADSys4,
and Michal has integrated it into the Online Package Manager.
A simple 3D example is also included.
Here is a video where you can see the 3D example: https://www.hackcad.com/maindownloads/cadsys43_3d_test.mkv.
Best regards,
Maurog

Hi! That's great news. I watched the video, and the coord system origin marker looks very strange with arrows that are not parallel to the grid.

Hello, thank you for your feedback. I don’t work with the 3D version, and honestly, I don’t have much knowledge in the 3D field either. I just compiled and ran the program on Linux. Since Piero is really very busy, he doesn’t participate in the forum. I will try to forward your concern to him.

Best regards,
Maurog

In a perspective view, the distances between the grid lines become smaller the further you move away from the origin. This is due to perspective distortion, which is used to create depth and spatial representation.

Therefore, it is correct that the three arrows (representing the axes of the coordinate system) cannot be parallel to the grid lines. They align with the coordinate axes and appear distorted or tilted in perspective.

If one wants to see parallel arrows, one would need to switch to an orthogonal view, where no perspective distortion is applied. (Chat-GPT). ???

Attached are the revised files to run the simplecad3d example, which does not run in Lazarus in its current form. The CADSys4 component also underwent a minor correction to enable 3D usage in Lazarus; however, there are still many VCL/Delphi features that are not compatible with LCL/Lazarus.

Do you still have the file?

Seems the site is not accessible, and archive.org also doesn't have it.

The version available in the Online Package Manager (OPM) was just successfully compiled and executed by me on mxLinux (Debian).

The OPM version is cross-platform and works with Lazarus on both Linux and Windows.

Here is a video I just created demonstrating it:

The link in the first post is broken because I have taken my homepage offline.
