LineWorld

An open source program to render meshes in 3D, written using pygame.

Controls:

w - move forward along the x-axis
x - move backward along the x-axis
a - move forward along the y-axis
d - move backward along the y-axis
z - move forward along the z-axis
e - move backward along the z-axis

t - move ward in the current direction
b - move ward in the current direction

j - increase the polar angle (theta)
l - decrease the polar angle (theta)
i - increase the azimuthal angle (phi)
k - decrease the azimuthal angle (phi)

Installation:

1. Ensure that python version 3 is installed.
2. Ensure that pygame is installed.
3. Download all the .py files in the src folder.
4. Run main.py

Creating meshes:

Different meshes can be created using the API provided in write.py. An example of a toroidal mesh is given in scratch.py.

A mesh is a list of structures, where a structure is one of the three following objects:

• Line, defined by a list of two points. A line can be generated using the add_line(point1, point2) function in write.py.
• Curve, defined by a list of two or more points. A curve can be generated using the add_curve(points) function in write.py, where points is a list of points.
• Surface, defined by a list of two or more lists of two or more points. A surface can be generated using the add_surface(points) function in write.py, where points is a list of lists of points.

Once all the structures have been defined, the write() function can be called to write the mesh into mesh.json, from where the mesh is loaded everytime main.py is run.
