Expand description

Per-frame state derived from a Camera + screen parameters.

Fields§

§pos: [f32; 3]

Camera position in world voxel units, narrowed from f64.

§right: [f32; 3]

Camera basis — right / down / forward.

§down: [f32; 3]§forward: [f32; 3]§xs: [f32; 3]

Transposed basis: row-major if camera basis was column-major. xs.0 = right.x, xs.1 = down.x, xs.2 = forward.x, etc.

§ys: [f32; 3]§zs: [f32; 3]§add: [f32; 3]

add[k] = -dot(pos, basis[k]), the translation half of the world → camera-relative-coords transform.

§corn: [[f32; 3]; 4]

Four-corner view-frustum direction vectors.

§nor: [[f32; 3]; 4]

Frustum edge normals: nor[i] = corn[i] × corn[(i + 1) % 4].
