Feeling lazy, Gemini please re-write my entire C++ library in python and ensure all the unit test I wrote (originally in C++) are also ported and tested. Seems to be doing ok so far (will most likely run out of free credits soon!) but am liking the @zed.dev Gemini integrations

Yay autodesk fixed the commandPort in 2025 (been busted for a while in our lab build), just got @zed.dev editor to send python to maya via a task (and some python scripts) as well. Next step to get python hints etc working. Think I will move all teaching to Zed next year.

This took way longer than I thought, converted one of my Lab C++ Particle Systems to #WebGPU, need work. #GraphicsProgramming #NCCA #Python

Co-pilot is so good for docstrings and type hints :-) saves loads of time, just need to proof read.

Been Busy marking, but managed to do some more of my WebGPU demo. Re-factor the Qt Widget, Text Rendering and sorted the lights a bit. #WebGPU #GraphicsProgramming #Python #NCCA

Replicating some of the functionality I have in my C++ NGL library in #WebGPU and #Python Need to take a step back and make some big design decisions on how to make a flexible library for students to use easily. This is very ad-hoc at present. #GraphicsProgramming

Taken a day to figure out how to set and render multiple objects in the same pipeline using an MVP matrix for each transform. So used to OpenGL having to re-design what I do with this, going to be hard to teach! #WebGPU #GraphicsProgramming #Python

Re implemented most of the primitives from my ngl library (c++) into python. Seems to work ok, need to add a few more procedural ones and convert Tri stips to Triangles. #WebGPU #Python #GraphicsProgramm

A productive day, got a decent line + colour shader pipeline developed (will turn it into a class soon), mouse controls for Qt interacting with the uniforms. First primitive in my primitives class developed. #WebGPU #Python #GraphicsProgramming

More WebGL progress, not using the Provided Qt Canvas but my own. Can update buffers and render directly to a QWidget. Just need to improve the synch code now. Think I'm going to port a load of my C++ code to python first so I can test other things such a better geo etc.

300 lines of python to draw a simple WebGPU cube, (+ approx 60 lines of shader code). It's a nice compromise between Vulkan and OpenGL but going to be hard to teach. Got a year to get something sorted, still not sure if the depth buffer is quite correct.
