How GJK Works
The GJK algorithm initializes with two points, one from each object. It iteratively finds the Minkowski difference, also known as the support function, between the two objects and computes the direction of separation. The process continues until the Minkowski difference is zero, indicating intersection, or a maximum number of iterations is reached without intersection.

Essential Questions and Answers on Gilbert Johnson Keethi in "MISCELLANEOUS»UNFILED"
What is the Gilbert Johnson Keethi (GJK) algorithm?
The Gilbert Johnson Keethi (GJK) algorithm is a computational geometry algorithm that efficiently finds the closest points between two convex bodies in n-dimensional space. It is a widely used tool in various fields such as computer graphics, robotics, and computational physics.
How does the GJK algorithm work?
The GJK algorithm iteratively constructs a Minkowski difference between the two convex bodies and finds the closest point on the boundary of this difference. By updating the difference based on the closest point, the algorithm converges to the closest point between the original convex bodies.
What are the advantages of using the GJK algorithm?
The GJK algorithm has several advantages:
- Efficiency: It is typically faster than other methods for finding closest points between convex bodies, especially in higher dimensions.
- Robustness: It can handle degenerate cases where the closest points are not unique or lie on edges or vertices of the convex bodies.
- Generality: It works for any pair of convex bodies, regardless of their shape or orientation.
What are the applications of the GJK algorithm?
The GJK algorithm has numerous applications, including:
- Collision detection in computer graphics and robotics
- Path planning for autonomous vehicles and robots
