Fig. 2.

Unity workflow: The blue arrows describe the workflow to project only one frame. The purple arrows describe the workflow to project the shadow processed from the whole simulation. A directional light projects the glycan’s shadow over an oriented plane (A). This shadow is rendered into a render texture by a camera (B) and either displayed on the surface for a static structure or, with a MD trajectory, converted into a Texture2D object (C). This object is read and combined with the images from previous frames (D). All the results acquired along the MD simulation are merged together into a final Texture2D (E) object which is then used in the projector, thus displaying it onto the protein surface (F).
