/ As a subcontractor to Ghost in Denmark, we did 4 VFX-shots for the danish film Vølvens Forbandelse. We were in charge of creating the entrance to a magic tunnel in which the two main characters travels between the future and the past. The work mainly consisted of matte paintings, but also some animation and dynamic simulations.

We started off by doing a 3D-model of the tunnel. This was
matched up to the original plates, got some texturing and was rendered
out as a still image for each shot. These renders were given some more
detail in Photoshop by adding dirt textures, small rocks and the green
glow effect. Finally the matte paintings were tracked and composited
into the filmed plates.
For the final shot we also did the
closing of the magic tunnel. This included some dynamic simulation and
hand animation of the rocks and dirt covering up the hole. Everything
got shading and lighting to match the original plate. On top of this a
few layers of simulated dust where added to further enhance the magic
effect.
