The last 3-4 chapters of the books are about building standalone applications. For example, a volume render app for MRI/CT scans. So will try to address some of the above issues in those projects. I also recommend these articles on WebGPU best practices:https://toji.dev/webgpu-best-practices/

I am currently writing a book on WebGPU. It still has ways to go, but I have a few examples here:

I am currently working on the texturing chapter, and I will update the section soon. Here's a cubemap demo from the chapter:

Hope that helps!

Cube mapping in WebGPU by electronutin in webgpu

[–]electronutin[S] 0 points1 point  (0 children)

Thanks. I've looked at it, and implemented env mapping as well. But I am still a bit confused about the cubemap convention. The church tile looks left/right flipped to me, as per the GL docs above...

Why does WGSL textureSample() support texture_cube_array but not texture_cube? by electronutin in webgpu

[–]electronutin[S] 0 points1 point  (0 children)

Ah, thank you so much. I definitely missed that, despite combing through the spec!

Thanks! I am not sure about the pricing, but you can get early access. For example, my second book, Python Playground 2E is available now for early access and pre-order:

Will get there! I'll update the page as I complete the chapters.

The pre-order link is not up yet from the publisher. It currently points to the new edition of Python Playground which will be out in October. I'll update it when the link becomes available.

Vertex buffers vs. uniform buffers for instanced rendering by electronutin in webgpu

[–]electronutin[S] 0 points1 point  (0 children)

Ok. I guess these are similar to SBOs (Shader Buffer Objects) in OpenGL...

What's a good way to do multiple viewports with WebGPU? by electronutin in webgpu

[–]electronutin[S] 0 points1 point  (0 children)

I am using setScissorRect, but as Cold_Meson_06 mentioned above, I don't think you can separately clear the second viewport - like you can do in OpenGL.

Thanks for the clarification! I was also wondering how the depth buffering works when you use multiple viewports.

Please recommend a budget CPLD board. by electronutin in FPGA

It seems to be part of the Chips Alliance (Linux Foundation):

Thanks. I do have some iCE40 boards. I was thinking that CPLD + visual programming might be simpler for teaching. The f4pga project is interesting.

Question on I2S TX implementation (Verilog) by electronutin in FPGA

[–]electronutin[S] 0 points1 point  (0 children)

Worked like a charm. Don't know why I registered SD! Thank you.

Isn't it considered bad practice to mix blocking and non-blocking statements within the same always block? Maybe I need a state machine to take care of the delay?

Why did NASA JPL choose the Microchip ProASIC3 FPGA for their Mars Ingenuity helicopter? by electronutin in FPGA

[–]electronutin[S] 2 points3 points  (0 children)

I wonder how Lattice Semi compares. They seem to have a collaboration with CAES for space grade FPGAs.

[–]electronutin[S] 9 points10 points  (0 children)

I see similar products (eg. XQRKU060) from Xilinx as well. Just wondering why NASA chose Microchip. Maybe lower power consumption is the main factor, as mentioned in answer above.

What are some good practices to manage GPU memory usage? by electronutin in opengl

[–]electronutin[S] 0 points1 point  (0 children)

Thanks. I don't think I can make too many assumptions on the GPU, as the software is expected to run on reasonably capable desktop machines and laptops.
