OpenGL software instead of WebGL hardware. What went wrong?

I am on R2025a.

---

Test Case #1

If I enter these commands.

info = rendererinfo;
disp(info)
disp(info.Details)

Then, these are the outputs.

GraphicsRenderer: 'WebGL'

Vendor: ''

Version: ''

RendererDevice: ''

Details: [1×1 struct]

HardwareSupportLevel: 'Full'

SupportsDepthPeelTransparency: 1

SupportsAlignVertexCenters: 1

SupportsGraphicsSmoothing: 1

MaxTextureSize: 0

MaxFrameBufferSize: 0

---

Test Case #2

If I enter these commands.

figure
ax = gca;
info = rendererinfo(ax);
disp(info)
disp(info.Details)

Then, these are the outputs.

GraphicsRenderer: 'OpenGL Software'

Vendor: 'Microsoft Corporation'

Version: '1.1.0'

RendererDevice: 'GDI Generic'

Details: [1×1 struct]

HardwareSupportLevel: 'None'

SupportsDepthPeelTransparency: 0

SupportsAlignVertexCenters: 0

SupportsGraphicsSmoothing: 0

MaxTextureSize: 1024

MaxFrameBufferSize: 0

---

These are the system specs:

---

The CPU is Intel i3-2310M with its integrated GPU of Intel HD Graphics 3000.

The GPU supports OpenGL 3.1 and the CPU supports OpenCL 1.1 according to AIDA64.

Also with DirectX DDI 11.1, it suports Feature Level 10_1, Shader Model 4.1, and WDDM 1.2

---

From webglreport.com, it states that the system support both WebGL 1.0 and WebGL 2.0

Questions

1. In Test Case #1, why are the values for Vendor, Version, RendererDevice, MaxTextureSize, and MaxFrameBufferSize missing from the rendererinfo output? What went wrong?
2. In Test Case #2, If OpenGL has been completely removed in R2025a, why does it still use the OpenGL 1.1 software renderer instead of WebGL? What went wrong?
3. How do I choose the WebGL version and its ANGLE backend (D3D9, D3D11, OpenGL, etc.) to compare the performance?

Datapoints:

MacOS Intel R2025a, I get

GraphicsRenderer: 'WebGL'

Vendor: 'Google Inc. (ATI Technologies Inc.)'

Version: 'WebGL 2.0 (OpenGL ES 3.0 Chromium)'

RendererDevice: 'ANGLE (ATI Technologies Inc., AMD Radeon Pro 5700 OpenGL Engine, OpenGL 4.1)'

Details: [1×1 struct]

HardwareSupportLevel: 'Full'

SupportsDepthPeelTransparency: 1

SupportsAlignVertexCenters: 1

SupportsGraphicsSmoothing: 1

MaxTextureSize: 16384

MaxFrameBufferSize: 16384

When I run on Windows 10 as a guest operating system in a Parallels virtual machine, I get

GraphicsRenderer: 'WebGL'

Vendor: 'Google Inc. (0x00001AB8)'

Version: 'WebGL 2.0 (OpenGL ES 3.0 Chromium)'

RendererDevice: 'ANGLE (0x00001AB8, Parallels Display Adapter (WDDM) (0x00004005) Direct3D11 vs_5_0 ps_5_0, D3D11)'

HardwareSupportLevel: 'Full'

SupportsDepthPeelTransparency: 1

SupportsAlignVertexCenters: 1

SupportsGraphicsSmoothing: 1

MaxTextureSize: 16384

On my Geekom Mini Air running Windows 11 natively, I get

GraphicsRenderer: 'WebGL'

Vendor: 'Google Inc. (Intel)'

Version: 'WebGL 2.0 (OpenGL ES 3.0 Chromium)'

RendererDevice: 'ANGLE (Intel, Intel(R) UHD Graphics (0x000046D1) Direct3D11 vs_5_0 ps_5_0, D3D11)'

HardwareSupportLevel: 'Full'

SupportsAlignVertexCenters: 1

SupportsGraphicsSmoothing: 1

MaxTextureSize: 16384

MaxFrameBufferSize: 16384

The Geekom has an Intel N100 CPU with built-in UHD graphics.

@Walter Roberson So what does it mean in my case? Why it could be missing in the first place?

[Walter Roberson]

If you have not already done so, I would suggest reinstalling MATLAB.

[James Richard]

@Walter Roberson It doesn't work.

I've just added a second test case. If OpenGL has been completely removed in R2025a, then why does it still use the OpenGL 1.1 software renderer instead of WebGL?

There is clearly a lack of documentation on the implications of the rendererinfo function in case it outputs something weirds.

[Walter Roberson]

When I test MacOS Intel R2025a, renderinfo(ax) gives me the same result as plain renderinfo()

[James Richard]

@Walter Roberson

Your MacOS is using Radeon Pro 5700 GPU to render and not the integrated graphics. Perhaps try your VM or the Geekom.

It’s clearly strange that WebGL works in Chrome and Firefox, but not in MATLAB.

[Walter Roberson]

My test with my VM showed the same output for renderinfo() and renderinfo(ax)

... I had to search around a lot to even find out that my MacOS Intel apparently has UHD 630 built-in. That fact is not mentioned anywhere in the specifications or system report; I had to hunt around to third-party model reports of the CPU model number, and then look up the specifications for the CPU model number.
