Assignment 2: Robotic Body and Camera movement

-It's required to use the robotic arm designed in assignment 1 and draw a whole body with cubes and sphere for the head, implement all type of movements, and set up camera to move around the body using a mouse or keyboard keys.

Changes in code

• Designed the body, head, knees, feet, shoulders, elbows, and hips; starting with glPushMatrix(); and ending with glPopMatrix(); for separation purposes:

    
    //Draw Body
    glPushMatrix(); //original push

    glRotatef(angle2, 1.0, 0.0, 0.0);
    glRotatef(angle, 0.0, 1.0, 0.0);
    glTranslatef(-1.0, 0.0, 0.0);
    glTranslatef(1.0, 1.0, -2.0);

    glPushMatrix(); //1
    glScalef(1.0, 2.0, 0.5);
    glutWireCube(2.0);
    glPopMatrix(); //1

    // Draw Head
    glPushMatrix(); //2

    glTranslatef(-1.0, 3.0, 0.0);
    glTranslatef(1.0, 0.0, 0.0);

    glPushMatrix(); //3
    glScalef(1.0, 1.0, 1.0);
    glutWireSphere(0.5, 10, 8);
    glPopMatrix(); //3

    glPopMatrix(); //2

• Adjustments to glTranslatef() for each block to fit as a robotic body.

• Added extra constraints to keyboard() for all keys to prevent unrealistic motion.

• Added camera zoom in/out keys to keyboard(), keys of rotations about the horizontal direction and vertical direction to specialKeys() for each block to fit as a robotic body.

Issues encountered

• After adding the camera keys, we encountered a weird movement and the body disappeared after a couple of rotations. The problem solved by revising the code and making sure we were working on the correct view and the camera-related functions were correctly implemented.

• One of our friends "Youssef Mohamed" suggested creating a default case for the camera angles and link it with a keyboard key, it was a good idea and now key '0' is responsible for resetting the view angle.

• Moreover, We Struggled a bit to understand and visualize the whole body with its rotations correctly.
