函数

函数	描述
localFrameToFixedFrameGenerator	Generates a function that computes a 4x4 transformation matrix from a reference frame centered at the provided origin to the provided ellipsoid's fixed reference frame.
eastNorthUpToFixedFrame	Computes a 4x4 transformation matrix from a reference frame with an east-north-up axes centered at the provided origin to the provided ellipsoid's fixed reference frame. The local axes are defined as: The x axis points in the local east direction. The y axis points in the local north direction. The z axis points in the direction of the ellipsoid surface normal which passes through the position.
northEastDownToFixedFrame	Computes a 4x4 transformation matrix from a reference frame with an north-east-down axes centered at the provided origin to the provided ellipsoid's fixed reference frame. The local axes are defined as: The x axis points in the local north direction. The y axis points in the local east direction. The z axis points in the opposite direction of the ellipsoid surface normal which passes through the position.
northUpEastToFixedFrame	Computes a 4x4 transformation matrix from a reference frame with an north-up-east axes centered at the provided origin to the provided ellipsoid's fixed reference frame. The local axes are defined as: The x axis points in the local north direction. The y axis points in the direction of the ellipsoid surface normal which passes through the position. The z axis points in the local east direction.
northWestUpToFixedFrame	Computes a 4x4 transformation matrix from a reference frame with an north-west-up axes centered at the provided origin to the provided ellipsoid's fixed reference frame. The local axes are defined as: The x axis points in the local north direction. The y axis points in the local west direction. The z axis points in the direction of the ellipsoid surface normal which passes through the position.
headingPitchRollToFixedFrame	Computes a 4x4 transformation matrix from a reference frame with axes computed from the heading-pitch-roll angles centered at the provided origin to the provided ellipsoid's fixed reference frame. Heading is the rotation from the local east direction where a positive angle is increasing eastward. Pitch is the rotation from the local east-north plane. Positive pitch angles are above the plane. Negative pitch angles are below the plane. Roll is the first rotation applied about the local east axis.
headingPitchRollQuaternion	Computes a quaternion from a reference frame with axes computed from the heading-pitch-roll angles centered at the provided origin. Heading is the rotation from the local east direction where a positive angle is increasing eastward. Pitch is the rotation from the local east-north plane. Positive pitch angles are above the plane. Negative pitch angles are below the plane. Roll is the first rotation applied about the local east axis.
fixedFrameToHeadingPitchRoll	Computes heading-pitch-roll angles from a transform in a particular reference frame. Heading is the rotation from the local east direction where a positive angle is increasing eastward. Pitch is the rotation from the local east-north plane. Positive pitch angles are above the plane. Negative pitch angles are below the plane. Roll is the first rotation applied about the local east axis.
computeIcrfToCentralBodyFixedMatrix	The default function to compute a rotation matrix to transform a point or vector from the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes to the central body, typically Earth, fixed frame axis at a given time for use in lighting and transformation from inertial reference frames. This function may return undefined if the data necessary to do the transformation is not yet loaded.
computeTemeToPseudoFixedMatrix	Computes a rotation matrix to transform a point or vector from True Equator Mean Equinox (TEME) axes to the pseudo-fixed axes at a given time. This method treats the UT1 time standard as equivalent to UTC.
preloadIcrfFixed	Preloads the data necessary to transform between the ICRF and Fixed axes, in either direction, over a given interval. This function returns a promise that, when resolved, indicates that the preload has completed.
computeIcrfToFixedMatrix	Computes a rotation matrix to transform a point or vector from the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes to the Earth-Fixed frame axes (ITRF) at a given time. This function may return undefined if the data necessary to do the transformation is not yet loaded.
computeMoonFixedToIcrfMatrix	Computes a rotation matrix to transform a point or vector from the Moon-Fixed frame axes to the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes at a given time.
computeIcrfToMoonFixedMatrix	Computes a rotation matrix to transform a point or vector from the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes to the Moon-Fixed frame axes at a given time.
computeFixedToIcrfMatrix	Computes a rotation matrix to transform a point or vector from the Earth-Fixed frame axes (ITRF) to the International Celestial Reference Frame (GCRF/ICRF) inertial frame axes at a given time. This function may return undefined if the data necessary to do the transformation is not yet loaded.
pointToWindowCoordinates	Transform a point from model coordinates to window coordinates.
rotationMatrixFromPositionVelocity	Transform a position and velocity to a rotation matrix.
