The following section shows the effect of offline rendering:
Next is the dynamic rendering
Since the test was not done with professional equipment, the detail of the model was definitely not good enough, but both the test and the previous model after scanning with professional equipment were too messy for post-processing the normals at a low cost due to the overly messy uv’s.
Note: Subsequently I tried to import the noise model’s forced direct conversion to fbx or obj format from sketchfab to achieve the perspective effect, but this didn’t work.
