Public Attributes | |
value_type | _v [3] |
General purpose double triple for use as vertices, vectors and normals.
Provides general math operations from addition through to cross products. No support yet added for double * Vec3d - is it necessary? Need to define a non-member non-friend operator* etc. Vec3d * double is okay
