pub struct Ball { pub radius: f32, }
Expand description

A Ball shape.

Fields

radius: f32

The radius of the ball.

Implementations

Computes the world-space AABB of this ball transformed by pos.

Computes the local-space AABB of this ball.

Computes the world-space bounding sphere of this ball, transformed by pos.

Computes the local-space AABB of this ball.

Creates a new ball from its radius and center.

Computes a scaled version of this ball.

If the scaling factor is non-uniform, then it can’t be represented as ball. Instead, a convex polygon approximation (with nsubdivs subdivisions) is returned. Returns None if that approximation had degenerate normals (for example if the scaling factor along one axis is zero).

Outlines this ball’s shape using polylines.

Discretize the boundary of this ball as a triangle-mesh.
