This is a homework from JLU's computer graphics lesson.
Function
- Draw a cube using Bresenham to draw a line.
- Switch through the menu to display the orthographic and oblique isometric projections of the cube.
- Use keyboard to control the panning of this cube.
- Use mouse to control the rotation of this cube.
Library Usage
This is a library called BasicDraw, which is made by me and has some userful tools build from scratch like drawing a pixel and a line.
To initialize this tool, you need to have Tk imported, and create a window. For example,
from tkinter import Tk
from BasicDraw import BasicDraw
window = Tk()
panel = BasicDraw(window, 1920, 1080)
panel.draw_pixel(0, 1, color="#f0f0f0")
panel.draw_pixels(((0, 1, "#f0f0f0"), ), custom_color=True)
panel.draw_pixels(((0, 1), ), custom_color=False)
panel.draw_line(0, 0, 100, 100, color="#f0f0f0", enable_warning=True)
panel.draw_lines(((0, 0, 1, 1, "#f0f0f0"), ), custom_color=True)
panel.draw_lines(((0, 0, 1, 1), ), custom_color=False)
panel.clear()
panel.draw_rectangle(((0, 0), (0, 4), (4, 4), (4, 0)), custom_color="#f0f0f0")
panel.polygon_fill(((0, 0), (0, 4), (4, 4), (4, 0)), color="#f0f0f0")
# Pass verticals of 6 faces
panel.draw_cube(((0, 0, 0), (), (), (), (), ()), rot_x=0, rot_y=0, rot_z=0, method="正")The init method of BasicDraw takes 4 arguments, which are:
- The tk object.
- Width of the panel.
- Height of the panel.
- Color of the background (Default is "#ffffff").
You can see other method's usage above.
When finish drawing, do not forget to call the tkinter.mainloop() to maintain the window.
Notice
Since performance issues, I've changed my custom draw method from bresenham to tkinter's create_line
when I ensure my bresenham works properly. When using my method, it is 5 FPS in PC, 60 FPS in M1 macOS,
which is unbearable. If you want to experience the origin version, please edit the draw_line method in BasicDraw,
comment line 66-70 and uncomment line 64-65.
