Overview

In addition, to the main library, we also provide two useful tools for visualizing meshes and 2D functions:

mesh_viewer: Script for visualizing meshes, whose path is given as an input.
func_viewer: Script for visualizing functions given from the command line.

Moreover, we also provide various examples that better showcase the functionalities of simple-3dviz.

mesh_viewer

mesh_viewer allows you to visualize a mesh, whose path is given as an input from the command line. It is possible to specify the camera parameters (position, viewing direction and "up" vector), the position of the light as well as the parameters of the launched window (size and background color). Moreover, it is possible to save the content of the scene by pressing "ctrl + S".

mesh_viewer --help
usage: mesh_viewer [-h] [--size SIZE] [--background BACKGROUND]
                   [--camera_position CAMERA_POSITION]
                   [--camera_target CAMERA_TARGET] [--up UP] [--light LIGHT]
                   [--color COLOR] [--use_tab20] [--manual]
                   [--save_frame SAVE_FRAME] [--direct_render DIRECT_RENDER]
                   [--with_texture]
                   file [file ...]

                        The position of the camera
  --camera_target CAMERA_TARGET, -t CAMERA_TARGET
                        The target of the camera
  --up UP               The up vector
  --light LIGHT

  --with_texture        Load mesh with texture

func_viewer

func_viewer allows you to visualize a function whose expression is given from the command line. It is a simple tool that allows for fast visualization of various 2D functions.

func_viewer --help
usage: func_viewer [-h] [--n_points N_POINTS] [--xlim XLIM] [--ylim YLIM]
                   [--colormap COLORMAP] [--log_colors] [--size SIZE]
                   [--background BACKGROUND]
                   [--camera_position CAMERA_POSITION]
                   [--camera_target CAMERA_TARGET] [--up UP] [--light LIGHT]
                   [--no_axes]
                   function
