Once you have opened a Maxima session, load package draw and then set global variable draw_renderer to vtk:
load("draw") $
draw_renderer: 'vtk $
Prisms are defined by the center (midpoint of its height), number of lateral faces, the coordinates of any point situated on a line containing a lateral edge, height, and direction. This scene is exported to VRML format, with WRL extension, and visualized with help of the three.js Javascript library. You need a modern browser to interact with the objects:
draw3d( terminal = vrml, color = gold, capping = true, prism([1,1,1],8,[2,0,0],4,[0,0,0]), color = gray, capping = [true,false], prism([0,0,0],5,[1,3,2],2,[1,2,-6]) ) $
For a better understanding of the arguments, run this code:
draw3d(
head_length = 0.5,
line_width = 0.1,
axis_3d = false,
/* x- axis */
color = red,
vector([-8,0,0],[16,0,0]),
/* y- axis */
color = green,
vector([0,-8,0],[0,16,0]),
/* z- axis and direction vector */
color = blue,
line_width = 0.3,
head_length = 1,
vector([0,0,0],[0,0,5]),
/* the prism */
color = yellow,
prism([0,0,0],8,[4,4,10],6,[0,0,5]),
/* edge and edge point */
point_type = sphere,
color = white,
points([[4,4,10]]),
line_width = 1,
points_joined = true,
point_type = dot,
line_type = dashes,
color = black,
points([[4,4,13],[4,4,-13]]),
/* labels and indicators */
color = red,
font_size = 1,
point_type = dot,
line_width = 1,
line_type = solid,
label(["Center (0,0,0)", -5, -5, -8]),
points([[0, -5, -8], [0, 0, 0]]),
label(["Direction (0,0,5)", -5, -5, 5]),
points([[0, -5, 5], [0, 0, 3]]),
label(["Point on edge line: (4,4,10)", -5, -5, 10]),
points([[5, -5, 10], [4, 4, 10]]) ) $
