Expand description

Per-scanline frustum data — what the grouscan ray-walker consumes (R4.3c+). Values match voxlap’s globals one-to-one.

Fields§

§vd0: f32

Left ray’s projected world (x, y). Voxlap’s vd0 then rescales it to ground-plane principal-axis units; this struct holds the rescaled value.

§vd1: f32

Magnitude of the right ray’s ground-plane vector (sqrt(vx1² + vy1²)). Voxlap’s vd1.

§vz0: f32

Left ray’s projected world z.

§vx1: f32

Right ray’s projected world (x, y, z).

§vy1: f32§vz1: f32§gixy: [i32; 2]

Voxel-column step in the ray’s direction. gixy[0] = ±1 (x step), gixy[1] = ±vsid (y step).

§gpz: [i32; 2]

Distance to next voxel-grid line in PREC-fixed-point. Lane with smaller value is the next-to-cross.

§gdz: [i32; 2]

Per-column-step delta added to gpz after a column advance.
