I want to see all the three right pyramids with different colors so that I can see them, and rotate in 3D?
`tetrahedron` is the function that I know, but I can't do it on my own. Or with any other 3D plot?Tue, 06 Jun 2017 17:24:02 +0200https://ask.sagemath.org/question/37814/how-to-draw-three-pyramids-inside-a-right-prism/Answer by John Palmieri for <p>I want to draw three right pyramids, which together make up a prism.

<p><code>tetrahedron</code> is the function that I know, but I can't do it on my own. Or with any other 3D plot?</p>
https://ask.sagemath.org/question/37814/how-to-draw-three-pyramids-inside-a-right-prism/?answer=37816#post-id-37816The `tetratrahedron` function only constructs a regular tetrahedron, it seems, so you need to construct yours by hand. The `polygons3d` function works for this: you specify a list of vertices and also a list of polygons made up of those vertices. For example:
faces = [(0,1,2), (0,1,3), (0,2,3), (1,2,3)]
vertices = [(0,0,0), (1,0,0), (0,1,0), (0,0,1)]
T1 = polygons3d(faces, vertices, color='red')
will use the specified vertices and then construct triangles using vertices numbered 0,1,2 from the list, and vertices 0,1,3, etc. You can write a function that does this:
def Tetrahedron(vertices, color='red'):
faces = [(0,1,2), (0,1,3), (0,2,3), (1,2,3)]
return polygons3d(faces, vertices, color=color)
T1 = Tetrahedron([(0,0,0), (1,0,0), (0,1,0), (0,0,1)], color='red')
T2 = Tetrahedron([(1,0,0), (0,1,0), (0,0,1), (1,0,1)], color='green')
T3 = Tetrahedron([(0,1,0), (0,0,1), (1,0,1), (0,1,1)], color='blue')
