Duplicate death stranding scan effect

Production idea

Scanning effect：
     1 World coordinates are reconstructed using depth maps, and distance maps are calculated using scene world coordinates and scan start coordinates
    
     2 Service SDF + frac + smoothStep Make scan lines and scan ranges
    
     3 Scanning range * Scanning line to Get the scan line in the range,   use DOTWEEN with c# to make scan animation

outline：
     1 Depth map + Sobel kernel to draw stroke
    
     2 Use a depth map as a stroke mask to reduce the intensity of distant strokes
    
     3 Control stroke display with scan range

Ground indicator：
     1 Array ray detection is used to query the mark position and normal line, and the mark type is distinguished by the normal line
    
     2 The Async method is used to apportionate collisions detected in multiple frames, consuming from 15.07ms per frame to 0.17ms per frame
    
     3 The ground marks are drawn in batches using the GPU Instance method, and the vertex shader redraws the face pieces as Billboard
    
     4 Manually writes the depth in frag shader to solving the problem of shading the mark and the ground
    

Particle：
     1 Particle instances are created when the tag is generated and automatically destroyed after play
    

Final effect：
