Quick procedural clouds in Houdini -> fbx -> Fusion -> stl

w/ simd_quatf(from:, to:) … Have been playing with Vectrex style line drawing on the Vision Pro … using thin cylinders though prob better to use a box or perpendicular planes.

let mid = SIMD3(
            x: (from.x + to.x) / 2,
            y: (from.y + to.y) / 2,
            z: (from.z + to.z) / 2 )
        
        let len = simd_distance(from, to)

        let v1 = simd_float3(0.0, 1.0, 0.0)
        let v2 = simd_normalize( simd_float3(
            (to.x - from.x),
            (to.y - from.y),
            (to.z - from.z) ))

        let line = ModelEntity(mesh: .generateCylinder(height: len, radius: 0.001), materials: [mat])
        line.orientation = simd_quatf(from: v1, to: v2)
        line.position = mid
