While this is still very crude, it may show you, what I intended to do: In the second picture, I used a "lightdome" a dome of 164 point-lights, coloured according to their position inside the skyfield.. While this is still very crude and positions are not correctly set at the moment, picture number 02 shows a distinct atmospheric lightning. Now for the question. I used a geodesic dome, split apart into its 164 faces. I exported this dome into Vue d'Esprit via Wavefront Object and ungrouped the object inside Vue d'Esprit. I simple used the parts-list to mark every object, setting a point-light into the center of every face until I had a dome of 164 point-lights. These pointlights were crudely coloured to fit the colour of their background in the skydome - very crudely to be true. None of these pointlights does cast a shadow or is volumetric or has a lens-flare. This is supposed to simulate the global lightning effect of radiosity. Now for you programmers at E-On-Software or anyone who is capable to do such a thing: Is it possible to create a "lightdome" object for Vue d'Esprit? This lightdome needs to have the following qualities: The density and amount of lights need to be variable. The lights must automatically take the colour of their background of the skydome. The lights need to decrease and increase their strength with their position relative to the sund. Those closer to the sun need to be stronger than those opposed to the sun. On a lightdome with a diameter of 3000 Vue-Units, lightstrength should vary between 5 for the off-side to about 50 on the sun-side. Thats it... just a mad idea, but it may just be possible, to give vue at least a tiny glimpse of radiosity even if full radiosity is still far away. Maybe it would be possible to create a plugin, that adds a small source of light to every glowing object. This source should not cast shadow and its strength should be set by the amount of luminosity and glow of the glowing object. This would further enhance the pseudo-radiosity-feeling. Oh, and by the way: Does anyone know, if there is a kind of "Vue d'Esprit"-SDK available? Joerg Weber
