Here is the video showing the problem: https://drive.google.com/file/d/1Al0fyuYutYJGRLcRsW4szCJfg0JiW3wj/view If you take the candle and move it near the left end of the boat, sometimes light toggles off (it should not). |

For portal flow culling in idRenderWorldLocal::CullInteractionByLightFlow, I use idBox::PlaneSide method. Note that idBox is ORIENTED bounding box, i.e. is stores 3x3 matrix for local coordinate system. Here is how the method is implemented (it has been like this since the very beginning): int idBox::PlaneSide( const idPlane &plane, const float epsilon ) const { float d1, d2; d1 = plane.Distance( center ); d2 = idMath::Fabs( extents[0] * plane.Normal()[0] ) + idMath::Fabs( extents[1] * plane.Normal()[1] ) + idMath::Fabs( extents[2] * plane.Normal()[2] ); if ( d1 - d2 > epsilon ) { return PLANESIDE_FRONT; } if ( d1 + d2 < -epsilon ) { return PLANESIDE_BACK; } return PLANESIDE_CROSS; } As you might notice, "axis" member is not used, so local coordinate system is ignored here, that's why portal flow culling ignores it completely. I think this bug happens under two conditions: 1) entity's rotation is not identity 2) model is stretched in 1/2 dimensions, i.e. does not look like a box/sphere |
