<BLOCKQUOTE>General purpose double triple for use as vertices, vectors and normals.
|
||
|
|
Provides general maths 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</BLOCKQUOTE>
