Feature request: 3D projection

[marceline-cramer]

I'd like to use vger in 3D (and eventually VR) for anti-aliased, GPU-accelerated Bezier rendering. All of the drawing operations would be projected onto a flat 2D plane observed through a 3D perspective camera. Is this possible to implement in vger, and if so, how can I help out?

Hi! Thanks for your interest in vger.

Fortunately, vger already uses 4x4 transformation matrices in the shader:

vger-rs/src/shader.wgsl

Line 472 in 2d52c8b

xforms: array<mat4x4<f32>>,

Will need to update the transforms to be 3D:

vger-rs/src/defs.rs

Line 14 in 2d52c8b

pub type LocalToWorld = Transform2D<f32, LocalSpace, WorldSpace>;

And of course add 3d versions of the transform functions on the vger struct.

Wow, that's really great to hear! Vger is a really amazing library and I can't wait to start using it :)
