Example . Isosurfaces

In this example we use Blend4Web addon to export a 3D model online. The sample data is borrowed from a project focused on visualizing spatio-temporal patterns of pedestrian behavior using data gathered from public webcams. The data is visualized using an Isosurface created in Paraview. The shape of an isosurface shows the spatio-temporal evolution of pedestrian density. The time axis is represented as a color ramp draped over the isosurface.
