3D Map Canvas is black

[roya0045]

tested on 3.16.0 and 3.16.1 on windows 10, installed with osgeo. Two different machines no open GL.

No matter what I do the 3d canvas stays black. All the displays (tiles loading, compass) work as usual but when nothing displays, even if I use the zoom to full extent.

The measurement tool took some clicking about but works.

No opencl support is available on those machines. Machines are VM, issue not present on a normal laptop. 3D in 3.10 works as intended.

[roya0045]

I have installed 3.10.12 through osgeo on the machine with the mentioned issue. Rendering works as intended on 3.10.12. This rules out machine issues.

[roya0045]

Same behavior with standalone install on the affected machines.

[gioman]

Confirmed here too.

[roya0045]

@gioman is your machine without a dedicated gpus? The issue seems to occur on machine with integrated graphics on the ones I tested.

[gioman]

is your machine without a dedicated gpus?

yes, integrated gpu.

[roya0045]

@wonder-sk @nyalldawson @vcloarec I'm pinging you just in case. It seems that machine on win10 without dedicated GPU cannot render the 3D canvas anymore. If the issue was present on linux I would guess that the testing servers would also show that behavior unless they have a gpu. I'm not sure how common this is but I'm curious to know if this is a hardware limitation, how should this be handled?

With a fallback 'more basic' approach or simply not do anything and state that 3D can only be used in 3.10 for users with hardware limitation?

[vcloarec]

Two different machines no open GL.

Rendering works as intended on 3.10.12.

I found those two statement incompatible but maybe I am wrong... @wonder-sk do you know if Qt3D could work without open GL?

[roya0045]

@vcloarec I meant OpenCL as the message states "No OpenCL compatible devices were found".

[vcloarec]

@roya0045 ah! ok, is it possible to check the version of open GL of the machines ?

[roya0045]

With GPU Caps Viewer I got the following information:

GL_VENDOR: Microsoft Corporation GL_RENDERER: GDI Generic GL_VERSION: 1.1.0

[uclaros]

Is this reproducible on a real machine (not a VM)? It sounds like an issue between VM and OpenGL.

[gioman]

Is this reproducible on a real machine (not a VM)?

will check this.

[gioman]

issue not present on a normal laptop

Is this reproducible on a real machine (not a VM)? @uclaros seems the answer is in the description

[uclaros]

Wanted to make sure. Braking it down:

• On a machine without a dedicated GPU
• On a VM with win10 as guest os
• 3d view is black on 3.16.0 and 3.16.1
• 3d view works ok with 3.10.12

Missing info that could affect:

• host os
• hypervisor sw
• qt versions for working vs non working builds

[gioman]

• host os

• hypervisor sw

• qt versions for working vs non working buil

in my case:

host: ubuntu 20.04 hyp: virtualbox qt: using qgis installed with osgeo4w in the vm

[roya0045]

host: win, I would assume Hyp: citrix qt: osgeo version, can't recall

[uclaros]

working vs non-working qt3d version might be useful

[roya0045]

@uclaros i think its more about recent changes that are no longer feasible on some hardware (textures, etc) rather than simple dependencies issue.

[vcloarec]

i think its more about recent changes that are no longer feasible on some hardware (textures, etc) rather than simple dependencies issue.

As the GL_VERSION is quite low, indeed, I think it is a new feature that does not work with old opengl. But which one? No idea for now.

Is it possible to try with 3.12 or 3.14 ?

[uclaros]

Comparing the working vs non-working qt versions won't hurt anyway. I have similar black stuff on my taskbar after a recent qt upgrade:

[roya0045]

@vcloarec once I'm back from vacation I could try 3.12 and 3.14 to see.

[agiudiceandrea]

I can confirm the issue with QGIS 3.16.3 on a Windows 7 SP 1 64 bit (HP Pavillon dv6 - Intel Core i5) using the integrated graphics device (no OpenCL support).

GPU Caps Viewer reports: OpenGL: OpenGL 2.1 (92 ext) - Intel(R) HD Graphics GL_VENDOR: Intel GL_RENDERER: Intel(R) HD Graphics GL_VERSION: 2.1.0 - Build 8.15.10.2189

The issue doesn't occur using QGIS 3.10.1 or 3.14.16 on the same system.

All the tested QGIS versions are installed via OSGeo4W and use Qt 5.11.2.

[agiudiceandrea]

Also tested on the same system, same Qt version 5.11.2:

• QGIS 3.10.14, the issue doesn't occur
• QGIS 3.16.0, the issue occurs.

So it seems it could be some change, introduced between 3.14.16 and 3.16.0, that was not backported to 3.10 branch.

[roya0045]

@agiudiceandrea Should be a feature adding new capacities to 3d canvas, I suspect its was the material render but I'm not too sure.

[PeterPetrik]

@agiudiceandrea or @roya0045 based on https://qgis.org/en/site/forusers/visualchangelog316/index.html#d-features, it could be well shadows could you verify that you have shadows switched off?

[agiudiceandrea]

@PeterPetrik the "Shadows" are switched off. Anyway the options panel is different...

[michikommader]

QGIS 3.20.3 on Windows 10, Version 20H2, Laptop with both Intel HD 520 and NVIDIA GeForce 930 MX graphics cards and recent drivers:

• 3D view canvas stays black in default configuration where the 3D canvas is automatically rendered by the NVIDIA GeForce 930 MX chip.
• 3D view works well (but slow) with manual override telling qgis-bin.exe to be handled by internal Intel HD 520 chip at all times. This override is configurable either in NVIDIA Control Panel software or in Windows' own display settings.

[roya0045]

Issue seems resolved for me on 3.24

[Mouse2]

Still present on my machine on QGIS 3.24.3 when trying to display Geotiff raster in 3d Map view. Shadows off.

Kind Regards

[kannes]

Is there a list of the GL Extensions used by QGIS 3D available? Maybe that would help drill down on the issue.

[wonder-sk]

Few notes:

• anyone having issues on Windows - it would be useful to download GPU Caps Viewer (https://ozone3d.net/gpu_caps_viewer/) mentioned earlier, and do a screenshot of the first two tabs: "GPU" and "OpenGL"
• QGIS 3D currently asks for OpenGL 4.3 core profile
• runinng QGIS 3D in a virtual machine is likely not going to work - VirtualBox seems to only have support for old OpenGL versions (2.x I think), same for VMware (it has 3.x I think)
• if GPU Caps Viewer reports OpenGL 1.1, then this is using old opengl implementation in windows, and you should probably install driver for your graphics card (which will provide newer OpenGL version)
• some old graphics cards may not have capabilities for the newer versions of OpenGL - e.g. here's a list of Intel integrated cards (https://www.intel.com/content/www/us/en/support/articles/000005524/graphics.html), and some of them like HD Graphics 2000/3000 only provide OpenGL 3.1

[kannes]

• anyone having issues on Windows - it would be useful to download GPU Caps Viewer (https://ozone3d.net/gpu_caps_viewer/)

Without an ad blocker that site's downloads site is aggressively trying to make the user install malware :\ And the .exe triggers a malware warning on Windows 10 at least. I looked around, Esri and others recommend OpenGL Extensions Viewer. Also triggers a warning from Windows but at least the download page does not present the user with 5 malware download links :D What a crazy world.

I did some tests with VirtualBox, it seems to work alright with its Mesa SVGA3D driver and the default 128MB video RAM assigned to it:

Thanks @kannes for testing!

It makes sense that one needs to have guest extensions installed to be able to use any 3D.

Apologies for the GPU Caps Viewer web site - I always use ad blocker, so I did not notice some bad content there...

Can you please post more details about your setup? I am a bit confused as you mention both VirtualBox and the MESA SVGA3D driver - I thought the SVGA3D driver works with VMWare virtualization, not VirtualBox (https://docs.mesa3d.org/drivers/svga3d.html). Also on that matter, I see you get OpenGL 4.1 even though we ask for OpenGL 4.3 and SVGA3D should support 4.3 as well - at the end of the SVGA3D driver documentation page, there are some hints why you may be getting 4.1 instead of 4.3.

And by the way, what do you mean by "the same z-fighting vertex soup" ? A screencast may be useful :-)

I think it would be good if we checked in QGIS 3D views at the start what OpenGL version we got, and in case of some old one (like 1.1), we would show some more reasonable error message with hints or links to documentation.

I only noticed when I used the default browser in my VM, brrrrr what a feeling =)

• Stock Virtualbox on Archlinux
• Windows 10 machine from https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/ (sadly not available anymore)
• Stock Guest Additions installed to the machine by me later
• Enabled "3D acceleration" in the machine's settings

That's all! I guess Virtualbox added support for the SVGA3D driver, regardless of its origin at Vmware it seems to be free and open-source in Mesa.

And by the way, what do you mean by "the same z-fighting vertex soup" ? A screencast may be useful :-)

I'll make a new bug report later. It's seems a bit like pieces of geometry flipping their normals or something.

Apparently yes - Virtualbox >= 6.0 ships with SVGA3D driver (https://www.phoronix.com/review/virtualbox-60-vmsvga), and it looks like originally it was just OpenGL 2.1, but probably since then, newer OpenGL versions were made available as well. Good to know!
