Volcanic eruption in Vatnajokull. Shot by Jon Gustafsson - http://www.JonGustafsson.com for http://www.ArtioFilms.com .
Wrote this when I posted this video:
Haven't really had time to watch the video. Volcano season keeps me pretty busy. I cut it on board the helicopter on the way back from the eruption. Threw some music from the fantastic composer Veigar Margeirsson (http://www.veigar.com) on it and posted it here.
It took us 90 minutes to fly to Grimsvotn with a strong wind against us. The eruption looked magnificent in the sunset. We got there at 11pm. Once we landed 5 miles away from the crater the cold glacier air hit us like a truck. We tried to work outside but I only lasted for a couple of minutes. Pilot Reynir Petursson also didn’t want to stay on the ground for too long since it was very windy and the ash fall was unpredictable. The light was also disappearing and he needs visual reference which is difficult on a white glacier. Once we got off the ground again we had to stay low because there were so many lightnings all around the eruption. Getting hit by a lightning in that strong wind, extreme frost and next to a live volcano was not desirable. We made it back to Reykjavik at 2am. Now the airspace has been closed in a 20 nautical miles radius because of ash.
Last time Grimsvotn erupted was in the fall of 2004. At the time I was making the documentary Wrath of Gods http://www.wrathofgods.com and the eruption became a part of the story.
Los trazados bezier resultan idóneos para el dibujo bidimensional, especialmente cuando contamos con un programa que los implementa de un modo sólido y robusto. En cambio, para trazar perfiles tridimensionales ya no son tan adecuados, pese a que estén disponibles para muchas aplicaciones 3D. Para esta labor resultan mucho más adecuadas las curvas NURBS.
