how to get the same point cloud rendering result as your paper?

[ImneCurline]

So far I have done some research and managed to export a point cloud file with colors in the same format as the paper and successfully used it to generate a mesh. The problem is that I need to get the same point cloud rendering as in the paper for the final presentation, but I don't know how your paper does the point cloud rendering. Could you please explain in detail how to render the point cloud to achieve the effect in your paper?

Thank you for your answer
