7315: r_useInteractionTable 2 will use std::map instead of the 2d array (some lights are broken) |
 |
Committed changes in svn rev 7318. Changed interaction table to a hash map with linear probing (see idDenseHash). Now it takes less space than interactions themselves, and works faster than std::map and list traversals. Still a bit slower than plain 2D table on CPU time though. Also removed cvar r_useInteractionTable. |

After looking better at how frontend, I have reignited the linked forum thread. Also: 1) restored the r_useInteractionTable cvar 2) extracted all the code of interaction table into idInteractionTable class 3) restored the old implementation with one huge light-entity matrix. 4) restored the old implementation without any table at all (list crawling) See commits 8181-8185. Right now by default r_useInteractionTable = 2, which is using single hash table (as it was before 8181). Note that you cannot change cvar during gameplay: there is no code to switch between implementations in runtime, and I don't think it is necessary (given that it won't be simple). |
