How to create 3D charts

(1/1)

mecoman:
Hi everyone. I need to create 3D charts. Do you know a library?
Thanks a lot, bye.

wp:
Not with TAChart, it is 2D only.

https://forum.lazarus.freepascal.org/index.php/topic,45683.msg323462.html#msg323462 shows an example how 3D charts could be drawn by means of OpenGL; it is not complete yet, maybe I can continue to work on it in the next days.

Otherwise, you could use a separate script-driven charting program such as gnuplot, catch its output and paint it in a TImage: https://forum.lazarus.freepascal.org/index.php/topic,23839.msg253759.html#msg253759, or https://forum.lazarus.freepascal.org/index.php/topic,40517.msg279940.html#msg279940

You can read this post on 3D: https://forum.lazarus.freepascal.org/index.php/topic,45506.msg323487.html#msg323487.
The videos mentioned here, explain step by step (source code written at the same time), how to create a 3D engine.
