Variable Layer Editing - OpenGL Error

[wywywywy]

Version

1.33.8-prusa3d-win64

Operating system type + version

Windows 7 x64

Behavior

When I click on the "Layer editing" button, an error message shows up -

Cannot compile an OpenGL Shader, therefore the Variable Layer Editing will be disabled.

Fragment shader compilation failed:
No errors.

Then the button becomes disabled.

I already have the latest driver from Nvidia.

Any ideas?

Thanks.

same thing here. win10 x64 opengl 3.3

The current code is patched using OpenGL 1.1 and outdated OpenGL extensions as this is the only OpenGL shader API supported by Perl. I am currently re-writing this piece of code into C++, so it will use OpenGL 2.0. This should fix most of these issues.

[bubnikv]

Would you please try the following alpha build, whether this solves your issue with the variable layer height editing?

Just please understand that it is an alpha. There has been a lot of work done on it, which was not properly tested yet, for example paralellization of many slicing steps and a revamp of the OpenGL visualization code.

Hi,

Just tried it and the layer editing doesn't error out any more. Hooray.

But the preview tab seems to have become very slow - is it related?

Thanks.

Which preview?

[bubnikv]

I have rewritten the 3D visualization to use Vertex Buffer Objects and OpenGL 2.0 shaders. What graphics card are you using? Would you please post a log generated by slic3r help menu -> system info?

[wywywywy]

See below. It's using the Intel GPU rather than switching to the Nvidia. Maybe that's the problem.

Ok I just updated the Intel driver and it's a lot better although not perfect.
Also the initialisation takes about 30s.

[bubnikv]

If you have an NVIDIA card installed, then switching to it in the NVidia application panel makes a huge difference. Just tried it today at one co-worker's computer.

Ok I just updated the Intel driver and it's a lot better although not

perfect. The Intel card is not perfect. Are you saying that the alpha is worse than the official 1.33.8 build?

Also the initialisation takes about 30s.

Which initialization? At which step?

@wywywywy Please provide additional information on what initialisation takes 30 seconds and whether it is worse than in 1.33.8. Otherwise I will close this issue.

I am going to release an official alpha soon, so we will collect more data on the behavior with the OpenGL vertex buffer objects.

[bubnikv]

The variable layer height visualization has been rewritten to OpenGL 2.0. Please use the current alpha 1.34.0.

Closing. Please feel free to reopen this issue, if you still have problems.
