Draw a parabola using Arcade in Python3

Arcade is a Python library which is used for developing 2Dimensional Games. Arcade needs support for OpenGL 3.3+. In arcade, basic drawing does not require knowledge on how to define functions or classes or how to do loops, simply we have inbuilt functions for drawing primitives.

Arcade inbuilt function for drawing parabola:-

1. arcade.draw_parabola_outline( ): This function draws the outline of a parabola. 

Syntax: arcade.draw_parabola_outline(start_x , start_y, end_x , height , color, border_width, tilt_angle)

Parameters:

• start_x : The starting x position of the parabola
• start_y : The starting y position of the parabola
• end_x : The ending x position of the parabola
• height : The height of the parabola
• color : The color of the parabola
• border_width: The width of the parabola
• tilt_angle : The angle of the tilt of the parabola.

Example:

Python3

# import module
import arcade

# Open the window. Set the window title and dimensions (width and height)
arcade.open_window(600, 600, "Draw  a parabola  for GfG ")

# set background
arcade.set_background_color(arcade.color.WHITE)

# Start the render process.
arcade.start_render()

# function to draw a parabola
arcade.draw_parabola_outline(50, 80, 100, 120, arcade.color.GREEN, 10, 0)

# finish drawing
arcade.finish_render()

Output:

2. arcade.draw_parabola_filled( ):This function is used to draw a color filed parabola.

Syntax: arcade.draw_parabola_outline(start_x , start_y, end_x , height , color, tilt_angle)

Parameters:

• start_x : The starting x position of the parabola
• start_y : The starting y position of the parabola
• end_x :The ending x position of the parabola
• height : The height of the parabola
• color : The color of the parabola
• tilt_angle : The angle of the tilt of the parabola.

Example :

Python3

# import module
import arcade

# Open the window. Set the window title and dimensions (width and height)
arcade.open_window(600, 600, "Draw  a parabola  for GfG ")

# set background
arcade.set_background_color(arcade.color.WHITE)

# Start the render process.
arcade.start_render()

# function to draw a parabola
arcade.draw_parabola_filled(25, 80, 100, 110, arcade.color.GREEN ,0)

# finish drawing
arcade.finish_render()

# to display everything
arcade.run()

Output:
