# TWA. Atlas F (Spideedoscope) *Relative*: [[Cosmoscope_3D]] *Theme*: the style of imagination ### Animation - Spider's legs (8) have segments (2-3 each) - 8 legs visually comprise 4 lines - Each leg sways side-to-side - Each segment periodically shakes - 1st group of legs shakes for a moment - In a brief moment the 2nd group shakes - Then they both stay still for a couple of seconds -- only swinging continues without stopping ### Functionality Use Line Renderer to represent the RayCast - You can shake it to reorder the "kaleidoscope" Comp: ```cs Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); int mask = LayerMask.GetMask("Ground"); RaycastHit hit; if (Physics.Raycast(ray, out hit, 1000, mask)) { Debug.DrawLine(ray.origin, hit.point, Color.green); // add interaction here CollideTarget.gameObject.SetActive(true); CollideTarget.position = hit.point + Vector3.up; // so it's not stuck in the ground ``` ### Research - **[[Афанасий Кирхер]]** (иезуит) создал **«проекционный фонарь»** / **волшебный фонарь** ([[Kaleidoscope|калейдоскоп]]): «давайте представим, что Бог может так сделать…».
