PopcornGL

A Python module based on my custom graphics engine.

This project is in open Alpha, and will improve depending on the attention it gets.

Requirements

Python versions tested: 3.9.6

Python modules needed:

• operator
• math
• copy

How to Install

To install PopcornGL you need to run the command pip install popcorngl in your command prompt. If the command does not work, create an issue relating the problem and I'll see if I can help you.

Classes

Camera(x_rotation, y_rotation, z_rotation, fov, center, distance)

This class is responsible for the camera in the scene.

Class Functions:
rotate_x(amount): rotates the camera a certain amount on the X axis around the center of the scene.
rotate_y(amount): rotates the camera a certain amount on the Y axis around the center of the scene.
rotate_z(amount): rotates the camera a certain amount on the Z axis around the center of the scene.
change_distance(amount): moves the camera further away from the object by a certain amount.

Class Variables:
x_rotation: the cameras rotation on the X axis.
y_rotation: the cameras rotation on the Y axis.
z_rotation: the cameras rotation on the Z axis.
fov: the cameras fov. (not actually the FOV I just didnt know what else to call it)
center: the center of the screen.
distance: the distance from the object in the scene.

Light(position, intensity, radius)

This class is responsible for the lighting in the scene. It's not necessary if you're not going to use it.

Class Variables:
position: The position of the light in the scene.
intensity: The intensity of the light.
radius: The range of the light.

Engine()

This class is responsible for functions that do math.

Class Functions:
do_3d_math(points, camera): This function returns the X and Y values of the points with 3D coords passed in it.
do_light_math(faces, points, light): This function returns the faces list with modification to the color based on the light.
sort_faces(faces): This function returns a sorted list of faces based on the depth of them in the scene (for painter's algorithm).
