Find code for drawFrame(), drawCubeArray() from 6-Viewing & Projection2 & mesh slides. E. DO NOT use gluLookAt() inside myLookAt() and glFrustum() inside myFrustum()! F. Your program should render the following scene: i. G. Hint: 1. To implement myLookAt(), see lecture slide 5-reference-viewing. To implement myFrustum(), see lab slide 6-Viewing & Projection2, mesh . 2. l2 norm of v : ||v|| = np.sqrt( np.dot(v, v) ) 3. a x b (cross product) : np.cross(a, b) def render(): glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT) glEnable(GL_DEPTH_TEST) glPolygonMode( GL_FRONT_AND_BACK, GL_LINE ) glLoadIdentity() myFrustum(-1,1, -1,1, 1,10) myLookAt(np.array([5,3,5]), np.array([1,1,-1]), np.array([0,1,0])) # Above two lines must behave exactly same as the below two lines #glFrustum(-1,1, -1,1, 1,10) #gluLookAt(5,3,5, 1,1,-1, 0,1,0) drawFrame() glColor3ub(255, 255, 255) drawCubeArray() def myFrustum(left, right, bottom, top, near, far): # implement here def myLookAt(eye, at, up): # implement here 4. a ȡ b (inner product) : np.dot(a, b) or a@b 5. Use glMultMatrixf() to multiply your projection matrix and viewing matrix to the current transformation matrix. H. Files to submit: A Python source file (Name the file whatever you want (in English). Extension should be .py) 2. Write down a Python program to draw following cube (ࢽִ (by using indexed squares representation and glDrawElements(). A. B. Length of each line is 1.5 C.
