ABSTRACT
The gradient mesh tool, implemented in vector graphics software like Adobe Illustrator, is a popular tool for creating and manipulating complex colour gradients. The mesh-based tool is restricted to rectangular gradient meshes, making it hard for the user to work with more complicated shapes such as shapes with holes. We propose a new gradient mesh tool that supports non-rectangular meshes, with native support for a wide range of different shapes. A user study indicates that our tool is easier to use when drawing colour gradients inside complicated shapes.

Image vectorization using optimized gradient meshes
Recently, gradient meshes have been introduced as a powerful vector graphics representation to draw multicolored mesh objects with smooth transitions. Using tools from Abode Illustrator and Corel CorelDraw, a user can manually create gradient meshes ...
Noisy gradient meshes: Augmenting gradient meshes with procedural noise
AbstractWe extend the gradient mesh vector graphics primitive with procedural noise functions. Specifically, we couple Perlin, Worley and Gabor noise to the gradient mesh. We allow local parameters controlling the noise functions to be defined ...
Locally refinable gradient meshes supporting branching and sharp colour transitions
We present a local refinement approach for gradient meshes, a primitive commonly used in the design of vector illustrations with complex colour propagation. Local refinement allows the artist to add more detail only in the regions where it is needed, as ...
