Second step : create a structure in Millumin, import your mesh (OBJ and DAE files are accepted), and move the camera, so the point-of-view is close to the final one (we will adjust it later). The first step is to create the mesh : you can easily do so with any 3D software such as Blender or Cinema 4D, but feel free to use VoxelCanvas in your browser, it is matter of seconds to create this pyramid of cubes ! The goal of this exercice is to create a simple anamorphosis of Mona Lisa on theses cubes, so the full image can only be seen from one point of view : In this example, our structure is made of cubes arranged as a pyramid : Indeed, it allows to import the 3D model, map it to the structure in real life, then adjust the anamorphosis point of view : this last step is crucial, so it works from the point of view of your audience, not the one of your videoprojector. This is where Millumin's structure becomes very handy. Of course, it is easier with a plane surface than a structure made of tens of surfaces (such as a pyramid of cubes). In brief, it is just a perspective transform, just as we are doing everyday in videomapping (with the 4 corners mapping tool). It is quite simple : the drawn or projected image follows a specific perspective, instead of the perspective of the surface.

Your browser does not support the video tag. For this purpose, it uses 3D softwares such as Unity or Cinema 4D. The structure is a concept in Millumin that helps to create 3D mappings, also called an anamorphosis.
