When can we expect to see this added to trueSpace? As I don't believe that any version, including 7.6, has this yet...
Considering radiosity calculations are one of the most process intensive tasks, often times even more then rendering, those of us with more then one core (or even more then one processor) would see a decent multiplier in speed... |

Radiosity is now "old tech" - it's only available in the Model side, from the Lightworks renderer, and as such is surpassed in speed and quality by HDRI there, and by GI in V-Ray. I haven't used radiosity since HDRI showed up in tS7.0 :)
There are no plans to update / redo radiosity calculations in tS (and in fact they aren't done in tS anyway, but in the render engine, so that would be a question for Lightworks rather than tS...)
HTH!

I suppose I shouldn't be surprised... :)
I always thought that GI, GA, and HDRI were not mathematically accurate... Better why to put it is: that they are not capable of calculating "100%" of the light distribution? Whereas GR can theoretically calculate every possible light bounce throughout the entire scene...
Am I making any sense, or do I not understand how the new methods work? |

Now that you mention it, when is trueSpace going to use the current version of lightworks? because I have looked at their site before, and seen many features that trueSpace still doesn't implement... |

Render engines are like cars, you can order one from the factory with all the bells and whistles or you can take one off the lot and get a better price break. Depending where your budget lies, decisions on extras and features will vary. |

Thats a good way to put it... |

Radiosity is only comparable with GI cos GI calculate the boucne of lights..
HDRI not.. HDRI simulate the color and intesity of an ambient light taken by a picture (with or without) an illumination channel, creating a realistic lighting.. but hdri doesn't include the bounce of rays of light..
So... Radiosity likes Thomas mentioned, is a "old" technology surpassed by GI cos is more faster and more optimized.. |

This I actually knew... and I have since also looked up Global Illumination, and (at least with lightworks) GI combines radiosity with final gather to get "the best of both worlds" |
