[SOLVED] CSE4020 - Computer Graphics - Lab Assignment 3

Description

Write down a Python program to draw a rotating triangle.

1. Set the window title and the window size to (480,480).
2. Draw a triangle using render() function below (DO NOT modify it!).

def render(T):     glClear(GL_COLOR_BUFFER_BIT)     glLoadIdentity()     # draw cooridnate     glBegin(GL_LINES)     glColor3ub(255, 0, 0)     glVertex2fv(np.array([0.,0.]))     glVertex2fv(np.array([1.,0.]))     glColor3ub(0, 255, 0)     glVertex2fv(np.array([0.,0.]))     glVertex2fv(np.array([0.,1.]))

glEnd()

# draw triangle glBegin(GL_TRIANGLES)

glColor3ub(255, 255, 255)     glVertex2fv( (T @ np.array([.0,.5,1.]))[:-1] )     glVertex2fv( (T @ np.array([.0,.0,1.]))[:-1] )     glVertex2fv( (T @ np.array([.5,.0,1.]))[:-1] )     glEnd()

1. Expected result: Uploaded LabAssignment3-1.mp4

1. Do not mind the initial angle of the triangle.
2. The triangle should be t rad rotated when t seconds have elapsed since the program was executed.
3. You need to somehow combine a rotation matrix and a translation matrix to produce the expected result

2. Write down a Python program to draw a transformed triangle.
3. Set the window title and the window size to (480,480).
4. Draw a triangle using render() function of prob 1 (DO NOT modify it!).
5. If you press or repeat a key, the triangle should be transformed as shown in the Table:

2. Be sure: gComposedM = newM @ gComposedM
