示例1: offset
void Visualizer::BodyFollower::generateControls(
const Visualizer& viz,
const State& state,
Array_< DecorativeGeometry >& geometry)
{
// Offset.
Vec3 offset(m_offset);
if (m_offset.isNaN()) {
// Default: offset is based on system up direction and ground height.
offset = Vec3(1, 1, 1);
offset[viz.getSystemUpDirection().getAxis()] += viz.getGroundHeight();
}
// Up direction. Default: use System up direction.
const UnitVec3& upDirection = m_upDirection.isNaN() ?
UnitVec3(viz.getSystemUpDirection()) : m_upDirection;
const Vec3 P = m_mobodB.findStationLocationInGround(state, m_stationPinB);
// Position of camera (C) from ground origin (G), expressed in ground.
const Vec3 p_GC = P + offset;
// Rotation of camera frame (C) in ground frame (G).
// To get the camera to point at P, we require the camera's z direction
// (which points "back") to be parallel to the offset. We also want the
// camera's y direction (which points to the top of the screen) to be as
// closely aligned with the provided up direction as is possible.
const Rotation R_GC(UnitVec3(offset), ZAxis, upDirection, YAxis);
viz.setCameraTransform(Transform(R_GC, p_GC));
