```cs public class TriangularPrismPrimitive : Primitive { // Length of the prism along its axis public float length; // Circumradius of the triangular cross-section public float radius; // This transform must only contain rotation and translation components, not scale public Matrix4F transform; } ``` > WARNING: the `transform` matrix should only contain rotation and translation operations, not scale. The size of the prism should be controlled via the `radius` and `length` properties
