Recommended way to load PNG into texture from include_bytes!() ?

[surban]

Hi!

I am embedding a PNG file in my Rust executable using the include_bytes!() macro. Is there a recommended way to load it into a three-d texture?

Thanks.

Sorry for the late reply. I should really make a simple function for doing that so it's easier to do, but it does only require 3 lines of code. You need to create RawAssets manually and insert the PNG bytes, then you can deserialize it as if you loaded the image. See the documentation of the insert method here: https://docs.rs/three-d-asset/latest/three_d_asset/io/struct.RawAssets.html#method.insert

Thanks!

This is what I did, but it felt a bit unnatural to do so.

Yeah, I know. It's because one 3D model file often consist of several files (geometry, material, textures etc.) so we need everything loaded before we can deserialize. There is probably a better design, but well, this was the best I could think of. I've added a deserialize function that can be used to deserialize a single file in 8c7097c 🙂

Thanks for the function.

However, when embedding resources using include_bytes! it would be necessary to copy the data using .to_vec() before calling deserialize. Would it also be possible to provide a function that takes &[u8], or at least &'static [u8]?
