Detailed Description
A radiosity Element, containing lightmap patches, the lumels.Radiosity rendering specific info is kept here.
Member Function Documentation
|
|
Add a fraction to delta map of lumel from given source RadPoly. suv is index in src, ruv is index in maps of this poly. |
|
|
computes new priority value, summing the light unshot. Note: Do no touch the variable total_unshot_light without doing a list->Delete(this), beforehand. |
|
|
Compute the texture map at the size of the lumel map. Gets the texture, and scales down. You must delete the map. |
|
|
light has been shot, copy delta to lightmap, clear delta, recompute priority. (this radpoly may not be in list as the total_unshot_light value changes). |
