Stoner is a grid-warping and upscale 'keystoner' tool. It has two levels of warping. First is a 4-point corner-pin. Within that is a mesh warper where for each point of the mesh you can adjust position and curvature using bezier handles. Stoner has 2 outputs:
- the final warped image and
- a displacement map which can be used in conjunction with the Remap TOP
On the Stoner custom parameter page you can also specify a custom COMP (usually a Base COMP will be perfect) where the displacement data and the displacement map are stored.
Note: Stoner is intended to be used to create the displacement map and then to be removed from the file with only the necessary data inside the COMP defined in the "Project" custom parameter staying behind. This will increase performance quite a lot and let you use one centralized Stoner instead of many.
You can find Stoner in the Palette under the folder Derivative>Tools.
Drag and drop the component from the Palette into your network.
Connect a TOP to the input of the Stoner component.
Open the Stoner interface by clicking the "Open Stoner Window" custom parameter on the node's Stoner parameter page.
