Description

This class is used to access camera objects in the scene. A camera can be divided into 3 main parts: the device body, camera lens, and viewing area. Therefore, the interfaces available are: aperture, focal length, angle of view, depth of field, near / far plane settings, and viewport fitting.

Inheritance: RIBase > RIObject > RICamera.

See Also: RCameraDofData, RScene.

camera = RLPy.RScene.FindObject(RLPy.EObjectType_Camera, "Camera")

# Set the camera transform values
control = camera.GetControl("Transform")
transform = RLPy.RTransform.IDENTITY
transform.T().x = -75.0
transform.T().y = -150.0
transform.T().z = 250.0
time = RLPy.RTime(0)
control.SetValue(time, transform)
# update after adding a key
camera.Update()

# Set the camera name
camera.SetName( "new_name" )

# Get camera bounds
ret_max = RLPy.RVector3()
ret_center = RLPy.RVector3()
ret_min = RLPy.RVector3()
ret = camera.GetBounds( ret_max, ret_center, ret_min )
print(ret)

# Get the camera pivot transform values
ret_pos = RLPy.RVector3()
ret_rot = RLPy.RVector3()
camera.GetPivot( ret_pos, ret_rot )
print(ret)

# Check whether or the camera is selected
RLPy.RScene.SelectObject(camera)
print(camera.IsSelected()) #True

Member Functions

# Add a DOF key
new_data = RLPy.RCameraDofData()
new_data.SetEnable( True )
