glpy

glpy is pyOpenGl wrapper which lets you work with pyOpenGl easily.It is not meant to be a replacement for pyOpenGl but runs on top of pyOpenGl to avoid most of the boiler plate setup

Features

• Robust abstraction over pyOpenGl event loop
• decorators to simplify callback functions

Code Example

from  glpy  import *
app = glpy()

@point(10)
def plotpoints():
    glColor3f(100, 150, 200)
    glVertex2f(0,0)
    
app.run(lambda:plotpoints())

Installation

pip install glpy

API Reference

glpy()

allowed keyword arguments

Parameter	Type	Description	Default
mode	constant	Display mode	GLUT_RGBA
size	tuple	Window size	(500,500)
position	tuple	Window position	(0,0)
bgcolor	tuple	background color	(0, 0, 0, 1.0)
title	string	window title	new title
axis_range	tuple	The range of 2D plane	(-100, 100,-100, 100)

How to use?

• Make sure you have opengl installed on your system

• Install the package using pip.

• import the package and initialilze glpy

  app = glpy()

• you can pass in additional parameters as seen in the API Reference as keyword arguments

  app = glpy(title = "line drawing")

• define your callback function with the help of point decorator which takes the size of the point to be plotted as an argument . NOTE: using a decorator is not neccesory for the library to work but it can significatly reduce the code size

  @point(10)
  def plotpoints():
      glColor3f(100, 468, 200)
      glVertex2f(0,0)
  

• call the run the method using the callback function as an argument to run the function NOTE: use a lambda function to pass callback functions with arguments

  app.run(lambda:plotpoints())

New Features

• @grid decorator:- this can be used as a higher level decorator to call back functions.It will create grid lines. This is still in beta and only work with default screen dimensions. Check out this example to learn more

• @line decorator:- this is similar to the existing point decorator, it can be used to draw a line easily checkout this example to learn more
