| void | R_DrawFlareSurfaces (const mBspSurfaces_t *surfs, glElementIndex_t *indexPtr) |
| Flares are batched by their texture. Usually, this means one draw operation for all flares in view. Flare visibility is calculated every few millis, and flare alpha is ramped up or down depending on the results of the visibility trace. Flares are also faded according to the angle of their surface to the view origin. | |
