C++ doesn't define these operations. They would be functions of a library or API that is working on some defined data sets.

Without further information, I'll assume you're talking about twelve dimensional inter-spatial manifolds. And my answer would be, I don't know how to do that....

But perhaps you're referring to DirectX, OpenGL or some other technology?

This smells like homework.

What object ?
Are you using OpenGL ? DirectX ?

Anyway, it's all more or less the same, you apply a transformation matrix to the object coordinates and let the system magically redraw the object with the transformation applied, or better, send the transformation matrix to the graphic system (with openGL, glPushMatrix, glMultMatrix,or wwith DirectX, D3DXMatrixTranslation, ... (but I'm no export on D3D) ) and send the vertices to the graphic system and the transformation will be done auto-magically.

If you do it manually, then you will have to do the transformation (matrix multiplcation, ...) in code, and there are tons and tons of example out there.

See http://en.wikipedia.org/wiki/Transformation_matrix[^] for maths of tranformation matrix.
