+1. `vec uv2 = 2.0 * uv - vec2(1.0); // should change 'vec uv2' to 'vec2 uv2', to make the argument type right`
+2. `H *= len * iResolution.x / iResolution.x; // should change to  'iResolution.x / iResolution.y', to fit in the screen size`
+3. `raycast(uv, dir, eye, ref); // should use uv2 rather than uv`
+4. `dir = reflect(eye, nor); // should use dir, which is the direction from eye to the intersection point`
+5. `for(int i = 0; i < 64; ++i) { // 64 is too small for ray casting iterations`
