Overview Download Alpha Shapes is based on efficient, discrete mathematics which determine exact relationships between points, shapes, and spaces. The software reconstructs surface and volume for a given point cloud.
Alpha shapes generates a family of shapes according to the selected alpha parameter.
It also computes metric properties of a selected shape, such as, volume, surface area, etc. A unique feature of alpha shapes is that it computes empty spaces around a shape, such as, voids and pockets.
