Camera And 3D

When To Use 3D

Use plain Scene for flat compositions and explanatory layouts. Use ThreeDScene when orientation, depth, or camera motion should affect the result.

Camera Basics

set_camera_orientation() establishes the initial 3D view immediately. move_camera()animates from the current camera state.

class SimpleCubeScene(ThreeDScene):    def construct(self):        self.set_camera_orientation(            phi=70 * DEGREES,            theta=-40 * DEGREES,            distance=8        )         cube = Cube()        self.play(Create(cube))        self.move_camera(phi=60 * DEGREES, theta=-15 * DEGREES, distance=7.4, run_time=1.8) 

Fixed Overlays

Use fixed-in-frame overlays for titles, HUD-like labels, and explanatory annotations that should stay attached to the viewport while the 3D world moves.

Scene Types

• Scene for flat timelines and 2D compositions.
• ThreeDScene for camera-aware 3D work.
• VoiceoverThreeDScene when narration and 3D camera motion need to share one timeline.
