Quat (Flowgraph Node)

Overview

• Node Name: Quat
• Category: repeat_instant
• File: extensions/flowgraph/nodes/types/quat.lua

Constructs a quaternion from four numeric components (x, y, z, w) and outputs it as a quat value.

Pin Schema

Input Pins

Output Pins

How It Works

1. work() - Reads x/y/z/w from input pins (defaulting to 0), constructs a quat, and outputs it as a 4-element table {x, y, z, w}.
2. drawMiddle() - Shows the quaternion string representation inline on the node.

Internals

• Uses a module-level quatOut to avoid per-frame allocation.
• Output is a plain table {x, y, z, w}, not a quat userdata - this is the standard flowgraph wire format for quaternions.

Example Usage

-- Construct identity quaternion
-- x=0, y=0, z=0, w=1
-- Output: {0, 0, 0, 1}

-- The node is equivalent to:
local q = quat(x, y, z, w)
self.pinOut.value.value = {q.x, q.y, q.z, q.w}

Additional Methods

C:_onDeserialized(nodeData)

Called after the node is deserialized (loaded from file). Restores runtime state from saved data.

Parameters:

• nodeData

C:_onSerialize(res)

Called when the node is serialized (saved to file). Returns data to persist.

Parameters:

• res

C:drawProperties()

Custom ImGui drawing function for the node editor.
