👉 Pre-expansion is a technique used in computer graphics to optimize the rendering of complex shapes by reducing the number of vertices and triangles required for their representation. Pre-expansion involves using fewer vertices and more triangles to represent a shape, which can significantly reduce the amount of data that needs to be stored or processed during the rendering process. This optimization can improve performance and efficiency, especially in environments where high-quality graphics are important. Pre-expansion is particularly useful when working with complex shapes, such as geometric objects
