Neutron Engine

Storms look cool, so why not add one to the engine Lightning and thunder generation is a part of dynamic weather system and it can be controlled like any other environment parameter over 24h cycle. The following video shows one possible scenario where storm forms after slightly overcast morning. For HD version please visit http://www.youtube.com/neutronEngine

After adding ‘time of the day’ feature next logical step was to add some weather effects. Dynamic cloud generator works with ‘humidity’ factor to decide on how cloudy the sky gets. The same factor can be used to determine when rain starts/stop falling so the weather changes dynamically.  Rain is completely simulated on GPU using geometry shader to convert particle points into rain drops. The following video shows one possible scenario where rain builds up after a relatively clear and sunny morning. The rainfall is light at the beginning with humidity reaching 65% and it gets heavier as we move towards 95% of humidity. For HD version please visit http://www.youtube.com/neutronEngine

Dynamic control of all environment properties in 3D engine is very important. Let’s face it, without it the 3D scene just does not look real. So, the logical step was to improve Neutron engine further and add this feature. All parameters related to wind,clouds,water, sky, fog,sun,moon,starts etc can be tweaked through 24h cycle using a simple editor. The results can be seen in this video, HD version can be found at http://www.youtube.com/neutronengine
