Origin Ver. and Service Release (Select Help-->About Origin): 2016 Pro (I have upgrade available, but haven't installed it!)
Operating System: WIn 7

Hi,

I have a 3D plot of a peaked data set and a projection underneath it using the 3D plot with projection feature (I think it looks awesome, but then I am biased!)

After a few hours of GUI tinkering I figured out how to control light source and the settings for the axes.

I would now like to make an animated plot which rotates the axes.
This needs still frames rendered at different angles.
Obviously, a for loop with the control parameters is required, with an export to image at each setting.

Is there an example script for 3D print settings that controls these parameters?
(I may have to rotate the light source with the axis, otherwise it is more like flying around to the shady side of the mountain!)

This is the kind of thing that you can do really easily in matlab, but when I did a quick google I didn't find any programmatic control.

Hi,

Please check LT cmd layer -3d r in the page below:
https://www.originlab.com/doc/LabTalk/ref/Layer-cmd#-3d_r.3B_set_the_3D_graph_rotation

You can also see their existing sample code 3D Surface Plot form Virtual Matrix (row2, col2):

Awesome - thanks!

My plot does look a bit like Mt. St Helens!

I'll share a vid when I have published it ;-)

3D graph light source is fully controllable from Labtalk, but unfortunately not yet documented.

You can find all the commands if you open the light source dialog and from Code Builder temp to open LightingControlDlg.cpp.

We will add the documentation shortly.

In case someone will be interested. I've found some hidden LT layer properties from one of their source file <exe folder>\OriginC\Originlab\LightingControlDlg.cpp

layer.light.direction.h
layer.light.direction.v
layer.light.diffuse
layer.light.kd
layer.light.specular
layer.light.ks
layer.light.shininess
layer.light.mode

to animate the rotation you mind still need to write a loop to do that manually.

Please note these commands do not trigger redraw, so "doc -uw" is needed after changes to redraw the graph.


Not sure if that can used together with the view together or not.
