An example of SDL3's new GPU API being used with Slang in the Odin programming language, supporting hot-reloading of the shader. This example is a modification of existing API examples:
The SDL3 GPU API is initialized by first telling it which shader formats you are able to provide it. Based on that list, SDL then selects the

This is a document detailing the planned approach for a rendering system I intend to implement, the reasons driving the approach, and the general rationale for the new design.
If you're interested in rendering APIs and want to look at different approaches, this document might be for you. I'm not claiming to be an expert in any field, especially not one as diverse and dynamic as rendering approaches, so treat everything here like I'm building a wall to keep good technology out and making you pay for it. In other words, consider whether better ways might exist and whether either of us are biased toward something.
