Get Camera FOV (Flowgraph Node)

Overview

• Node Name: Get Camera FOV
• Category: repeat_instant
• File: extensions/flowgraph/nodes/scene/camera/getCameraFOV.lua

Gets the camera's current Field of View (FOV) as an angle in degrees. Automatically switches to free camera if not already active.

Pin Schema

Output Pins

Behavior

• work() - Called every frame:
  1. If the camera is not in free camera mode, switches to it via commands.setFreeCamera().
  2. Reads the current FOV using core_camera.getFovDeg() and outputs it.
• drawMiddle() - Displays the current FOV value in the node editor UI.

Key Dependencies

• commands.isFreeCamera() / commands.setFreeCamera() - Free camera detection and activation
• core_camera.getFovDeg() - Returns current FOV in degrees

How It Works

This is a simple provider node that continuously outputs the current camera FOV. It forces free camera mode because FOV reading is only meaningful in that context.

Example Usage

-- Use in flowgraph to read FOV and conditionally adjust scene elements
-- Wire curFOV output to a comparison node to check if FOV is within a range
-- Pair with Set Camera FOV to create smooth FOV transitions
