Line
Line[{{x1_,y1_,z1_}, ..., {xn_, yn_, zn_}} | indexes_List]
represents a line in 3D space.
Graphics3D[{Black,Line[{{1, 1, -1}, {2, 2, 1}, {3, 3, -1}, {4, 4, 1}}]}]
Parameters
RGBColor
AbsoluteThickness
Indexed geometry
The most efficient way of using Line for many vertices is to wrap it into GraphicsComplex. It provides the list of vertices as a separate list, while Line contains only the indexes for a line
v = PolyhedronData["Dodecahedron", "Vertices"] // N;
i = PolyhedronData["Dodecahedron", "FaceIndices"];
GraphicsComplex[v, {Black, Line[i]}] // Graphics3D
Dynamic updates
It does support updates. Use Offload
tip
Updates of geometry using GraphicsComplex is more efficient for many vertices
warning
Changing the length of an array of points is not supported!
