I saw a video on YouTube where a person uses a transparant, knotted pyramid to display holograms using their smartphone. (I have not been able to reproduce this yet, so I can't tell for sure if it works).I was wondering, given a model, which transformations I should apply to get the different projections needed to produce this effect?
What transformations should I apply to a model to produce this 3D effect?
projections;transformations
