I've tested, and the patch you posted fixes the FLTK plotting crash, thanks.

I also tried converting the "renderer" to a pointer and then calling "new" within the OpenGL_fltk constructor.  That did NOT work.  Not quite sure what the issue is other than OpenGL initialization for FLTK is tricky.

Thank you, Dan, for pointing me to the issues you discovered in bug #48869. I am answering here to the issue there:

It is probably not necessary to call "get_maxlights" in the constructor of gl_render. If the current implementation causes problems, it should be possible to move "get_maxlights" to "draw_axes_children" (see attached changeset).
I am not seeing any segfaults on the systems where I ran my tests with this change or before. Can you please test whether this fixes the segfault for you?
I cannot comment on whether it would make (more) sense to move renderer() inside of the constructor for OpenGL_fltk. On the one hand, I am not familiar enough with the fltk code and, on the other hand, I cannot test whether this would fix the segfault.

Wrt your second question: num_lights counts all lights in the axes and within (nested) hggroups. The function from which your code snippet originates calls itself recursively for (nested) hggroups. "num_lights" is still initialized to 0 in draw_axes_children.

(file #38104)

I think this may have introduced an FLTK bug by calling an OpenGL routine outside of an instantiated Fl_Gl_Window.  See here:

I'm not sure how C++ orders initialization of something like

OpenGL_fltk (int xx, int yy, int ww, int hh, double num)
    : Fl_Gl_Window (xx, yy, ww, hh, 0), number (num), renderer (),
      in_zoom (false), zoom_box ()

but maybe if renderer() is moved inside of the constructor function it would work.

I have another unrelated question.  Initialization of num_lights was removed from before the loop, i.e.,:

-  // Start with the last element of the array of child objects to
-  // display them in the order they were added to the array.
-  num_lights = 0;

but it is still incremented somewhere within the loop.  How does one know that the member variable num_lights has been initialized?  Or is the idea simply to push num_lights as high as possible?

The last changeset for this particular patch is file #38047. It contains all changes to lights since they were added to Octave. Please, ignore all other patches and references for the time being.

Philip started reviewing it but he didn't finish before his (well earned) holidays.

I'm coming to this a little late, I guess.  There seem to be a lot of patches referenced in the comments below and I'm not sure of what should or should not be applied or in what order or whether things are fully ready to be applied to Octave.

Could someone summarize briefly?  I'd like to integrate the outstanding patches and I'm willing to review patches but I need a list of current patches that should be reviewed.

(1) the patch you made from task #11311 applies fine but gave rise to compile errors in After backing it out building Octave went w/o problems.

(2) "demo light" seems quit a bit aster now (on Linux, haven't yet tested on Windows).

I don't think I can spend much more time for Octave until mid-August. I wanted to review the code style etc of all patches (= the 5 mentioned in comment #28 + this one) but alas. If no one did by mid-August I can pick up again.

Could you please try the attached patch? It should apply on top of the others you have with a decently recent tip.

I cannot post on tasks (probably I lack the sufficient priviledges). I also had to do some decent merging to be able to apply the changeset from task #11311. It would probably be better if Pantxo rebased his patch because he knows probably better what he was doing when he wrote the patch in the first place. Anyway I will post the diff for that task that should apply on top of your patches here.

PS: Hint taken ;-)

That latest patch, patch_8943_light_update1_v6.patch_G, fails to apply here.
I add light.m.rej here

FYI I've applied:

in that order, AFAIK according to your instructions.

(task_11311_add_constraints.patch_F  (not: patch_11311....) also doesn't apply)

(As you can see I start all patches/csets with the bug/patch/task number, otherwise it'ĺl become a big mess on my HDD and I cannot backtrack what patch belongs to which  bug/patch/task report.  Hint!)

Philip, you are probably hitting bug #41277. I reduced the number of patches for the isosurfaces in some of the demos in the newest changeset here (file #37960).

That is only a change to "light.m" so you would not need to re-compile if you wanted to try whether that helps. The changes you would need to apply are in lines 250-286 in "light_update1_v6.patch". You might also try the new demos in lines 312-345 of the same file.

Philip, when you are going to make your next test build, could you please consider applying the latest patch from here, too, and run the demos for light?
The latest patch should apply cleanly on top of my other patches you were testing.

THis patch fixes additionally a bug when lighting edges of surfaces and adds demos for edge lighting to light.m.
It also removes the warning for "phong" in draw_surface.

With the latest patch the maximum number of lights is only checked once per Octave session instead of everytime when a OpenGL figure is touched.

It would be nice if the bug fixes and small new features included in this patch could make it into 4.2.0.

Wed 22 Jun 2016 07:03:38 PM UTC, comment #20: 

With the attached patch a warning is emitted when more lights are added than supported by the OpenGL implementation. I am unsure whether the warning id should be added to that warning.

The check for the actual number of lights (GL_MAX_LIGHTS is off for me in Ubuntu as well as Windows) was too late in the previous patch. So I moved it to the constructor of opengl_renderer. I hope this is OK.

I am getting the hang on calling "demo light 1" now as well intermittently. It seems to be reproducible when the demo is run immediately after starting Octave.
Interestingly, I can reproduce the hang with the following demo as well:

%! clf;
%! h_axes2 = subplot(2, 2, 1);

%! % comment
%! % comment

%! % comment
%! h_axes2 = subplot(2, 2, 3);

It might be related to some interference between the pager and subplot.
I will run some more tests and file a bug about this if I cannot find an open one.

Tue 07 Jun 2016 04:05:53 PM UTC, comment #19: 

I was looking for a way to add limit checks for the properties that control lighting for patches and surfaces. I found  task #11311 where Pantxo already implemented just that. I cannot comment on that task. This is why I am writing here.
That patch does currently not apply on the default branch (haven't checked stable). But with some manual merging, it seems to do its job perfectly.

Does the patch from task #11311 (or a rebased version of it) still have a chance of being pushed?

Fri 03 Jun 2016 06:31:05 PM UTC, comment #18: 

Yet another issue: At least for my system GL_MAX_LIGHTS is way too high (>3000). Yet, I start receiving GL errors when I add more than 8 lights.
I added a loop that tries how many lights can be disabled before GL-errors occur and stores that number in opengl_renderer::max_light.

There is a bug in the current implementation of light: If the light is part of an hggroup that was added after the patch or surface object, light effects are not rendered for those objects.

I think I have an idea why this happens and how to fix it. Should I post a patch here or file a separate bug for this?

Now that light is present in Octave, I will try and submit patches for adding related functions such as lighting, material and camlight.

Colin, are you interested in adding some of these functions as well? I might give a start to "material" first...

After running under gdb and finding where the demo hangs, it seems to be a problem with the pager, not with the graphics code.  Sorry for the trouble.

Found another spot in where the code differed slightly from other objects. However, that one should never be reached.

I edited the commit message, added an entry for the NEWS file, fixed a typo in @qcode and made a few other style changes.  My updated version of the patch is attached.

I was ready to push the change but when I try "demo light" Octave stops responding after showing a figure window with an empty axes object.

Code looks reasonable enough to me, but I'm not expert.

I did notice "scripts/plot/draw/light.m" has dos newlines.  I'm not sure what Octave policy is, but other files in scripts/plot/draw have unix newlines:

isonormals.m:  ASCII text
isosurface.m:  ASCII text

I updated the patch again to include:

- respect the setting of "specularcolorreflectance"

Additionally, I changed the default value of "facelighting" for surface and patch from "none" to "flat" to match MATLAB and added a bunch of demos to lights.m primarily to easily check if something goes wrong.

In the meantime, I managed to set up a cross compile environment.
At least for me, lights also work with Windows. yeah

The updated patch adds support for the three setting of "BackFaceLighting" for "patch" and "surface" objects.
It also fixes the error when using "gnuplot".

The patch #8951 adds automatic calculation of "VertexNormals" for "patch" objects. The checks for has_normals in this patch should be removed when/if patch #8951 is accepted.

I would very much appreciate if someone could test this patch and run

demo light

Mon 14 Mar 2016 03:24:17 PM UTC, original submission:  


attached please find a first try of getting lighting effects to work on patches and surfaces.

"light.patch" includes the changes to Octave core functions. "light.m" is the actual function called from Octave to add a light source to the current axes.

As I am neither an expert in C++ nor OpenGL programming, I am happy that it seems to work quite well at least for me. I would appreciate any help, tips, info and opinions.

The current implementation suffers the following limitations:
- Only one light source is supported. I might work on this on a follow-up patch if I figure out a way to handle this.
- The "VertexNormals" of "patch" objects must be set manually. I think I know how to calculate the normals automatically but I am still working out how to patch the "patch" objects correctly.
- Only light sources at infinity are supported.
- The setting of "BackFaceLighting" of the "patch" and "surface" objects is ignored. I might work on implementing "backlit" later as it seems to be a side effect when calculating patch normals.
- It only works with "qt" and "fltk". When adding a "light" object with "gnuplot", it fails with the following error and nothing is drawn:

error: __gnuplot_draw_axes__: unknown object class, light
error: called from
    __gnuplot_draw_axes__ at line 1363 column 9
    __gnuplot_draw_figure__ at line 172 column 17
    __gnuplot_drawnow__ at line 86 column 5

I am leaving this to a gnuplot expert, since I do not know how to handle this correctly. Just inserting an empty case for "light" did produce a lot of different errors...

If this patch (or an improved one) was accepted, it would be quite easy to add other related functions as e.g. lighting, shading, camlight or material.
