Description
1. Write a program that draws a color-changing cube. A. Set the window title to your student ID and the window size to (480,480). B. Start from the code in 7-Lighting&Shading slides. Draw a flat-shaded cube. Make sure FDPHUDPDQLSXODWLRQVKRUWFXWVěĜěĜěĜěZĜZRUN C. Use the following light setting: + 2021_ITE0000_2019000001 + LabAssignment7/ + 1/ – 1.py + 2/ – 2.py + 3/ – 3.py D. If you press or repeat a key, the diffuse & specular color of the light and the ambient & diffuse color of the object should be changed as shown in the Table: Key Action A Change the light color to red S Change the light color to green D Change the light color to blue F Change the light color to white Z Change the object color to red X Change the object color to green C Change the object color to blue V Change the object color to white E. Files to submit: A Python source file (Name the file whatever you want (in English). Extension should be .py) 2. Write a program that draws a smooth-shaded cube. A. Set the window title to your student ID and the window size to (480,480). B. Start from the code in 7-Lighting&Shading slides. Make sure camera manipulation VKRUWFXWVěĜěĜěĜěZĜZRUN C. Use glDrawElements(), not glDrawArray(). Refer the code in 6-Viewing&projection2, Mesh slides. i. Hint: In Gouraud shading, one vertex has only one normal. This makes using glDrawElements() easier. D. Use the following normal vector data: lightPos = (3.,4.,5.,1.) glLightfv(GL_LIGHT0, GL_POSITION, lightPos) ambientLightColor = (.1,.1,.1,1.) glLightfv(GL_LIGHT0, GL_AMBIENT, ambientLightColor) specularObjectColor = (1.,1.,1.,1.) glMaterialfv(GL_FRONT, GL_SPECULAR, specularObjectColor) glMaterialfv(GL_FRONT, GL_SHININESS, 10) E. If you press or repeat a key, the ambient & diffuse color of the object should be changed as shown in the Table: Key Action R On/Off the object color of red G On/Off the object color of green B On/Off the object color of blue F. Expected result: Uploaded LabAssignment7-2.mp4 G. Files to submit: A Python source file (Name the file whatever you want (in English). Extension should be .py)
