Tkinter - OpenGL Frame using ctypes
An opengl frame for pyopengl-tkinter based on ctypes (no togl compilation)
Collected together by Jon Wright, Jan 2018.
This example creates a window containing an OpenGLFrame
filling the entire window. We configure it to animate
(constantly redraw) clearing the screen using a green color.
A simple framerate counter is included.
The context information is printed to the terminal.
import time import tkinter from OpenGL import GL from pyopengltk import OpenGLFrame class AppOgl(OpenGLFrame): def initgl(self): """Initalize gl states when the frame is created""" GL.glViewport(0, 0, self.width, self.height) GL.glClearColor(0.0, 1.0, 0.0, 0.0) self.start = time.time() self.nframes = 0 def redraw(self): """Render a single frame""" GL.glClear(GL.GL_COLOR_BUFFER_BIT) tm = time.time() - self.start self.nframes += 1 print("fps",self.nframes / tm, end="\r" ) if __name__ == '__main__': root = tkinter.Tk() app = AppOgl(root, width=320, height=200) app.pack(fill=tkinter.BOTH, expand=tkinter.YES) app.animate = 1 app.after(100, app.printContext) app.mainloop()
