This technique is, of course, a lot less accurate than baking radiosity.

On the other hand, the realtime GI we saw in the LumenRT Advanced video reminds me of what we had in Artlantis 11 years ago: The software seemed to be placing additional "fill lights" in mid-air. Also, it's a solution that does not scale well, since you can't have both close-up illumination detail and a huge model. Once you get used to Lumion's real-time feedback, there's no going back. That's why I have steered clear from LumenRT until now. Unfortunately this method makes it very, very cumbersome to make changes and test variations, since there's no realtime feedback. Simulate how the light bounces from one triangle to another. Notice that each linear increase in mesh detail commands a square increase in polygon count. Divide the mesh in small triangles so each new triangle becomes a discrete element. Judging by my experience with 3dsMAX's radiosity, it seems to me that the LumenRT's "baked GI" is doing this: Let me know if you have any other questions. Think of it more like a mock-up that gives you "an idea" of what the real simulation might look like. It looks nice, but it is nowhere near as accurate as the physical simulation. This is what you see in the video, where the time of day is changed, and you can see the illumination of the building change accordingly. The big advantage of this is that results are instantaneous, and don't require any baking - lighting is updated in real-time, so it reacts immediately to changes in your scene). What this does is generate a quick approximation of indirect lighting, in real-time. This is not the same as a real, physical simulation of light. It's a real-time Global Illumination solution that we have developed and that will be available in a future version of LumenRT. Now what you saw in the video is something different. LumenRT manages to do this physical simulation of light very quickly (typically 15 minutes), despite the staggering complexity involved (e-on holds a number of patents on this technology, so you won't get that elsewhere). For better lighting, use the more advanced modes (Full lighting) that requires the preparation phase. But it doesn't feature realistic lighting. This produces nice results, of similar quality to other products like Lumion. However, if you want immediate results without having to wait for the baking, you use the Draft mode. Once this calculation is done, the scene can be displayed in real-time. This is why, in order to display its best quality, LumenRT requires a preparation phase (referred to as "baking") during which the physical lighting is calculated. Because this is an accurate simulation of light, it takes time. Please check the link below to get the example of some work performed with LumenRT.LumenRT performs a real, physical simulation of light.

LumenRT is a 32 & 64 bits application, designed for the Windows® 32/64 bits XP, Vista and Windows 7 as well as Intel Mac OS X platforms (v10.6+). LumenRT Review provides a great benefit to the architect for visualizing their project. With the new auto-scale lighting feature, the users can gain of up to 14 times on pre-processing time and improve performance by 30% to 300% depending on the size of the model with a resulting tradeoff of lower lighting quality. The sketchup users can process larger models such as large structures and cities with superior speed. Lumen RT is nominated as the plug-in of the year under the 3D World CG Awards 2011. The new release comes up with quality and reliability enhancements to get better performance and stability. E-on software unveils LumenRT Review 1.2 for sketchup.
