The Triangle Mesh node is a patch that is mostly used to map projection onto the surfaces of objects that are composed of triangular shapes.
In a typical setup, the Triangle Mesh node receives a source image as the input and outputs the modified image to the Display or Canvas node.
Example of the node graph with the Triangle Mesh node
To apply triangular mesh warping:
- Create and edit a triangular mesh by doing the following:
- Add control points. Position the cursor over the layout area, press the P key or left-click, and select Add Point in the drop-down menu to create a control point.
- Connect control points into triangular mesh faces. Select control points and press the T key, or left-click on the selection and choose Create Triangles in the drop-down menu to connect selected control points. If no control points are selected, pressing the T key connects all existing control points.
- Delete control points. Select control points and press the Del key or left-click on the selection, and choose Delete points in the drop-down menu to delete those control points.
- In the Output panel, modify the mesh grid by dragging the handles of the mesh control points.
- In the Input panel, define the mapping of the source image for the individual mesh triangles by dragging the handles of the mesh control points.
In addition, working with the Triangle Mesh patch follows the general principles for working with patches outlined in the Editing Patches section of the documentation.
