The Coordinate Space node changes the coordinate space of the image from rectangular to polar or from polar to rectangular.
Coordinate Space Node Inputs
The two inputs on the Coordinate Space node are used to connect a 2D image and an effect mask, which can be used to limit the distorted area.
- Input: The orange input is used for the primary 2D image that is distorted.
- Effect Mask: The blue input is for a mask shape created by polylines, basic primitive shapes, paint strokes, or bitmaps from other tools. Connecting a mask to this input limits the distortion to only those pixels within the mask. An effects mask is applied to the tool after the tool is processed.
Coordinate Space Node Setup
The Coordinate Space node is used below to make a circular pattern based on a Fast Noise, Mosaic Blur (DaVinci Resolve Resolve FX only), and a Transform node. The Crop node at the end is used to set the desired resolution.
Coordinate Space Node Controls Tab
The Controls tab Shape menu switches between Rectangular to Polar and Polar to Rectangular. Consider the following example to demonstrate the two coordinate spaces.
Coordinate Space Node Settings Tab
The Settings tab in the Inspector is also duplicated in other Warp nodes. These common controls are described in detail HERE.
