Parallelepiped  

Parallelepiped defined by corners P,Q,R and S:

A parallelepiped with the corners P,Q,R and S we get with a macro from "analytical_g.inc" :
Parallelepiped_by_Corners(P,Q,R,S, Rl, Rp, filled),
Here: Rl = radius of the edges, Rp = radius of the corners,
If the according radii are 0, this elements are not shown.
filled = 1, for filled surfaces.

Sample:

object{Parallelepiped_by_Corners(P,Q,R,S,Rl,Rp,0)
        pigment{ color YellowGreen }}
object{Parallelepiped_by_Corners(P,Q,R,S, 0, 0,1)
        pigment{ color Green ttansmit 0.5 }}

Parallelepiped with start at P and edge vectors V₁,V₂,V₂:

A parallelepiped with the starting point at P and the edge vectors V₁,V₂,V₂ we get by a makro from "analytical_g.inc" :
Parallelepiped_by_Edges(P,V1,V2,V3, Rl, Rp, filled),
Here: Rl = radius of the edges, Rp = radius of the corners,
If the according radii are 0, this elements are not shown.
filled = 1, for filled surfaces.

Sample:

object{Parallelepiped_by_Edges(P,V1,V2,V3,Rl,Rp,0)
        pigment{ color YellowGreen }}
object{Parallelepiped_by_Edges(P,V1,V2,V3,0,0,1)
        pigment{ color Violet transmit 0.5 }

Parallelepiped with start at P and edge vectors V₁,V₂,V₂

Sample:
