A Lower Bound for Proportion of Visibility Polygon's Surface to Entire Polygon's Surface: Estimated by Art Gallery Problem and Proven that Cannot be Greatly Improved

open access: yesConference on Computer Science and Information Systems, 2023
Assuming a bounded polygon and a point inside the polygon or on its boundary, the visibility polygon, also called the visibility region, is a polygon reachable, i.e., visible by straight lines from the point without hitting the polygon's edges or ...

A Simple and Correct Even-Odd Algorithm for the Point-in-Polygon Problem for Complex Polygons [PDF]

open access: yes, 2017
Determining if a point is in a polygon or not is used by a lot of applications in computer graphics, computer games and geoinformatics. Implementing this check is error-prone since there are many special cases to be considered.

Assessment criteria for 2D shape transformations in animation [PDF]

open access: yes, 1997
The assessment of 2D shape transformations (or morphing) for animation is a difficult task because it is a multi-dimensional problem. Existing morphing techniques pay most attention to shape information interactive control and mathematical simplicity ...
