Gregory's ServerIt sure took me long enough, but #ElegyEngine can now render textured models !!!
Also got a pretty colourful "missing texture" texture now. Should be very easy to notice and still look aesthetically pleasing

Also funny sidenote: I spent an entire day just figuring out why my cube model was facing the wrong way. Wrote a bunch of unit tests for the matrix maths, and everything was perfectly fine. Turns out I forgot to use "clear rotation" in Blender before exporting. The model itself was not rotated correctly. :blobfox3c: At least now I have some unit tests, so that's good. |
This took a lot longer than I expected to say the least:
Loading glTF and PNG files was the easy part; most of the effort went into the material/shader system.
Typically when you write a renderer, you can define which resources (textures, matrices etc.) occupy which slots in the shader. E.g. view & proj matrix -> slot 0, model matrix -> slot 1, textures -> slot 2.
But here I wanted a more data-driven thing, where the shader & renderer agree on a few common slots, and the rest it figures out from the material file. So you can easily just write a new shader and use it! No need to touch the renderer code at all.
There were lots of little nuances to this, so it took a while.
I also realised, however, that my renderer plugin API is pretty inflexible and flawed. I'll need to redo that next month. Oops!
