FMatrix3Rotate(FPoint3, Single, Single, Single, AxisType) Method

Rotate the 3D point by a specified angle, in radians.

C#
public static FPoint3 Rotate(
	FPoint3 point,
	float thetaX,
	float thetaY,
	float thetaZ,
	AxisType upAxis = AxisType.Z
)

Parameters

point  FPoint3
Reference to the point to be rotated.
thetaX  Single
The angle around the X axis by which to rotate the point, in radians.
thetaY  Single
The angle around the Y axis by which to rotate the point, in radians.
thetaZ  Single
The angle around the Z axis by which to rotate the point, in radians.
upAxis  AxisType  (Optional)
The optional 'up' direction axis used to help determine which axis is yaw.

Return Value

FPoint3
The rotated 3D point, relative to 0,0,0.

Remarks

The order of rotations is Yaw, Pitch, Roll, with the UpDirection helping to distinguish which axis is Yaw.

Yaw, pitch and roll are descriptions from the perspective of the pilot.

  • Yaw is left/right turning rotation with a constant horizon.
  • Pitch is forward/back rotation.
  • Roll is wingtip left/right rotation.
