Camera Look at Position (Flowgraph Node)

Overview

• Node Name: Camera Look at Position
• Category: repeat_instant
• File: extensions/flowgraph/nodes/scene/camera/cameraAutoRotate.lua
• Icon: Camera icon
• Color: Camera color

Sets the camera rotation to always look at a given target position. The camera's position stays where it is; only the rotation updates.

Pin Schema

Input Pins

Output Pins

None.

Internals

• Uses a constant up vector vec3(0, 0, 1).
• Switches to free camera mode if not already active.
• Computes look-at quaternion via quatFromDir(target - camPos, vecUp).

How It Works

1. Every frame, ensures the camera is in free camera mode (commands.setFreeCamera()).
2. Gets the current camera position via core_camera.getPosition().
3. Computes the direction from the camera to the target position.
4. Sets the camera rotation to face that direction while maintaining the up vector.

Lua Code Example

-- Make the camera always look at a vehicle:
-- vehiclePosition → cameraAutoRotate.position
-- Camera stays in place but tracks the vehicle.

-- Or look at a static point of interest:
-- cameraAutoRotate.position = {100, 200, 50}

Key Dependencies

• core_camera - getPosition(), setPosRot()
• commands.isFreeCamera() / commands.setFreeCamera() - camera mode control
• quatFromDir() - quaternion from direction vector

Additional Methods

C:work()

Main work function called each frame/tick when the node is active.
