Animation-Python

This repository contains a little script-collection to perform basic animations in python. by now it has some implementations to draw a 3d grid, an paper airplane (used for the first exaple in PATH.py), coordinate systems, 3d Lines. Moreover it cointains methods to calculate inverse kinematics, to build a 3d robot with joints with 3 degrees.

Getting Started

All the methods are in the "Auxs.py" and "Drawings.py" Scripts, so you only need to import them

Prerequisites & Installing

You need to install Opengl (pyOpengl) and numpy and pygame you can get all of them from pip. try with

pip install pyopengl
pip install numpy
pip install pygame

in your command line.

when finished you just need to clone this repository

Example usage

import pygame
from OpenGL.GL import *
from OpenGL.GLU import *
from Drawings import *

pygame.init()
display = (800, 600)
pygame.display.set_mode(display, DOUBLEBUF | OPENGL)
glMatrixMode(GL_MODELVIEW)
gluPerspective(45, (display[0]/display[1]), 0.1, 250.0)
glTranslatef(0.0, 5, -30)
glRotate(-45, 1, 0, 1)

link0 = Link((1, 1, 1), (1, 0, 0), direction= [0, 0, 1])
link1 = Link((.2, .2, 3), (0, 1, 0))
link2 = Link((.2, .2, 2), (0, 0, 1))
link3 = Link((.2, .2, 1), (1, 0, 1))
link4 = Link((.2, .2, 3), (0, 1, 1))
robot = Arm(link0, link1, link2, link3, link4)
point = np.random.random_sample(3)
while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            quit()
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
    # Draw a grid
    drawGrid(0)
    robot.follow(point)
    drawCoord(point)
    if target[1]:
       point = target[0]
    pygame.display.flip()
    pygame.time.wait(10)
