Struct DynSpriteTransform 

pub struct DynSpriteTransform {
    pub pos: [f32; 3],
    pub right: [f32; 3],
    pub up: [f32; 3],
    pub forward: [f32; 3],
}

Orientation + position for a dynamic sprite instance — the per-frame pose passed to SceneRenderer::add_sprite_instance_posed and set_sprite_instance_transform.

right/up/forward are the instance’s local axes expressed in world space (the columns of the model→world rotation), mapping directly onto the underlying Sprite’s s/h/f (kv6 local +x/+y/+z). They must be non-singular (det ≠ 0) but need not be orthonormal — a uniform/non-uniform scale or shear is fine. A near-singular basis falls through the renderer’s degenerate-basis guards and the instance silently skips that frame rather than panicking. Default is the identity basis (axis-aligned).

Fields

pos: [f32; 3]

Instance world position (the kv6 pivot maps here).

right: [f32; 3]

Local +x in world space ↦ Sprite::s.

up: [f32; 3]

Local +y in world space ↦ Sprite::h.

forward: [f32; 3]

Local +z in world space ↦ Sprite::f.
