| DT_DLL_vrfmodel double partElevationWrtBody | ( | const makVrf::DtArticulatedPartStateRepository * | part | ) |
These elevation and heading functions assume a constrained configuration of articulated parts on the entity. All turrets, i.e. parts that change heading, i.e. rotate on the z-axis, are assumed to be attached only to other turrets or the body. Thus the heading of a turret, or something attached to the turret, is a function only of the its own rotation and the rotation of turrets it is attached to.
Similarly, the guns, i.e. parts that elevate, i.e. rotate on the (z-rotated) y-axis, are only attached to other elevating parts, except their base which is a turret or the body. Thus the elevation of a gun is a function only of the its own rotation and the rotation of other guns it is attached to.
What is not covered is a turret that is attached to a gun (i.e., an elevating part); in this case the elevation angle of the something on the turret would depend not only on the elevation of the base gun, but on the angle of the turret.
Determines the part elevation angle With Respect To the body of the entity, including all articulated parts.
| DT_DLL_vrfmodel double partHeadingWrtBody | ( | const makVrf::DtArticulatedPartStateRepository * | part | ) |
Determines the part heading (yaw) angle With Respect To the body of the entity, including all articulated parts.
| DT_DLL_vrfmodel double headingToPointWrtBody | ( | const DtVector & | localTargetPoint, |
| const DtVector & | localPosition, | ||
| const DtDcm & | localOrientationMatrix | ||
| ) |
Determines the heading, with respect to the body coordinates of an entity at the given position with the given local orientation matrix.
| DT_DLL_vrfmodel double headingToPointWrtBody | ( | const DtVector & | localTargetPoint, |
| const DtSimObject * | entity | ||
| ) |
Determines the heading, With Respect To the body of the entity, to the given target point.
| DT_DLL_vrfmodel double headingToPointWrtPart | ( | const DtVector & | localTargetPoint, |
| const makVrf::DtArticulatedPartStateRepository * | part, | ||
| const DtVector & | localOriginLocation | ||
| ) |
Determines the heading direction to a point (local coordinates), With Respect To a coordinate system that is located at the given origin (local coordinates), and rotated to the heading of the given part. For example, the heading to a point directly to the right of a turret is pi/2. If a secondary gun were mounted on the turret at a location that is forward from the turret origin, its heading to the point would be slightly greater than pi/2.
| DT_DLL_vrfmodel double elevationToPointWrtBody | ( | const DtVector & | localTargetPoint, |
| const DtVector & | localPosition, | ||
| const DtDcm & | localOrientationMatrix | ||
| ) |
Determines the elevation, with respect to the body coordinates of an entity at the given position with the given local orientation matrix.
| DT_DLL_vrfmodel double elevationToPointWrtBody | ( | const DtVector & | localTargetPoint, |
| const DtSimObject * | entity | ||
| ) |
Determines the elevation, with respect to the body of the entity, to the given target point.
| DT_DLL_vrfmodel double elevationToPointWrtPart | ( | const DtVector & | localTargetPoint, |
| const makVrf::DtArticulatedPartStateRepository * | part, | ||
| const DtVector & | localOriginLocation | ||
| ) |
Similar to headingToPointWrtPart, but for elevation.
| DT_DLL_vrfmodel DtVector targetLocationOnEntity | ( | const DtVector & | localShooterLoc, |
| const DtSimObject * | targetEntity, | ||
| const Coordinate_System * | coordSys, | ||
| double | heightFraciont = 0. |
||
| ) |
Determines the point to target on an opposing entity.
| DT_DLL_vrfmodel bool checkLineOfSightTargetLaser | ( | const DtSimObject & | shooterObject, |
| const DtVector & | weaponGeocPosition, | ||
| const makVrf::DtLaserDesignatorStateComponent & | targetLaser, | ||
| const DtSimulationServices * | simulationServices | ||
| ) |
Determines if target laser spot is visible from the position of the shooter's weapon. The shooterObject could be the entity with the missile launcher or could be the laser guided missile itself. The weaponGeocPosition is the world position of the weapon launcher (on the shooter) or the world position of the missile. The target could be one of the following:
