Another example of the reverse animation technique. An advantage of building the animation starting with the end stage model, is in placing the fibrin strands. The strands look like they are forming around the clot of red blood cells and activated platelets. This was accomplished by uv mapping the strands, and then animating texture maps to revel the strand models. Because we are using reverse animation, the end stage model is a known shape, and the strand models can then be created around the layers of the end stage model, without intersecting the RBCs and platelet models.
