B4A 3D Surface Chart Example

[KitCarlson]

I have the need for a 3D surface chart, to show a two dimensional array of data values.
This is for a hobby project, for showing fuel and ignition timing tables. The data Z, would be indexed by X, Y.

Here is a javascript example using webGL. https://code.google.com/p/webgl-surface-plot/

I will pay $100 USD via paypal, for one working example in b4a.
I will share with b4x members. If $100 is not enough for work required, perhaps others with 3D chart needs, will help contribute too.

This can be done with my library Body3D (after slight modification of array sizes) here https://www.b4x.com/android/forum/threads/3d-bodies-four-libraries.48373/
It can be rotated by the user
If you want I can do it for you.
I tried to run it by BodyGl but it fails due to heavy workload on the OpenGl .

That is a good start. Is it possible to add axis titles, grids and plot color intensity?

 

[derez]

Yes. Color intensity is already in the picture.

 

[KitCarlson]

Excellent!

 

[derez]

20x20 and grid

 

[KitCarlson]

That is great!

Derez completed the task in an excellent fashion. Here is a screen shot:https://www.dropbox.com/s/5xvgcsegqrjksb8/Screenshot_2015-01-08-16-15-51.png?dl=0
