- Graphics programming for beginners is complex, starting with 'Hello Triangle' instead of 'Hello World'.
- Modern GPU programming focuses more on compute shaders than traditional graphics rendering.
- Vulkan compute is recommended as a starting API for GPU programming, with a focus on debugging and profiling.
- Using mid-level API abstractions like Granite can simplify initial learning without hiding the underlying API.
- Debugging tools like RenderDoc are essential for effective GPU programming.
- Vulkan GLSL is suggested as the initial shading language due to its documentation and features.
- Compute shaders allow for significant work without immediate need for complex synchronization.
- Understanding GPU execution models, workgroups, and subgroups is crucial for effective programming.
- Descriptors in Vulkan provide efficient ways to handle resources like buffers and textures.
- Porting ShaderToy shaders to compute can be a practical way to apply learning.
- Future learning paths include atomics, shared memory, subgroup operations, and eventually graphics pipeline.
