The 3D Figure class
Main author: Maël Godard
This page describes the class used in Codac for 3D visualization.
Figure3D
The basic class for 3D visualization is Figure3D. It is used to generate a .obj file that can be imported in any 3D visualization software.
For online visualization, the free website 3dviewer can be used.
The constructor takes one arguments: the name of the object file.
fig = Figure3D("my_object") # for the object file my_object.obj
Figure3D fig ("my_object"); // for the object file my_object.obj
Drawing functions
Below are the detailled available drawing functions. The shapes that can be drawn are:
- Geometric shapes
Box
Parallelepiped
- Paving
PavingOut (Paving with contractors)
PavingInOut (Paving with separators)
Subpaving
In addition, a function draw_axes is available to draw the three axes of the 3D space.
-
void codac2::Figure3D::draw_axes(double size = 1.0)
Draws the (x,y,z) axes on the figure in red, green and blue.
- Parameters:
size – Size of the axes
Note that only the stroke color is used in all of the supported drawing functions.
Geometric shapes
-
void codac2::Figure3D::draw_box(const IntervalVector &x, const StyleProperties &s = {Color::dark_gray(0.5)})
Draws a box on the figure.
- Parameters:
x – Box to draw
s – Style of the box (edge color)
-
void codac2::Figure3D::draw_parallelepiped(const Vector &z, const Matrix &A, const StyleProperties &s = {Color::dark_gray(0.5)})
Draws a parallelepiped z+A*[-1,1]^3 on the figure.
- Parameters:
z – Coordinates of the center of the parallelepiped
A – Matrix of the parallelepiped
s – Style of the parallelepiped (edge color)
Paving
-
void codac2::Figure3D::draw_paving(const PavingOut &p, const StyleProperties &bound_s = {Color::yellow(0.5)})
Draws a paving on the figure (Only the boundary is drawn).
- Parameters:
p – PavingOut to draw (result of a paving with contractors).
bound_s – Style of the boundary of the paving
-
void codac2::Figure3D::draw_paving(const PavingInOut &p, const StyleProperties &bound_s = {Color::yellow(0.3)}, const StyleProperties &in_s = {Color::green(0.5)})
Draws a paving on the figure (Only the boundary and the inside is drawn).
- Parameters:
p – PavingInOut to draw (result of a paving with separators).
bound_s – Style of the boundary of the paving
in_s – Style of the inside of the paving
