Business and Computing Deanery 3D Modelling Tools Week 14 – Animating cameras

3D Modelling Tools 2 Last week Animation Timelines Keyframes Constraints Video 3DS Max 7 Bible Chapter 29

3D Modelling Tools 3 This week Lecture Camera animation Following a moving object Moving a camera along a track Panning Orbiting Zooming 3DS Max 7 Bible Chapter 29

3D Modelling Tools 4 Concepts What is animation? Modification of any kind of object Light Material Camera What can you change? Parameters Position Rotation Scale What parameters have been changed? 3ds max v7

3D Modelling Tools 5 Cameras Virtual cameras duplicate the functions and controls of real-world cameras What controls does a real-world camera have? A. Focal length B. Field of View 3ds max v7

3D Modelling Tools 6 Focal length The distance between the lens and the light-sensitive surface Lens size 28mm wide angled lens 50mm normal lens 85mm long focus and more…. 3ds max v7

3D Modelling Tools 7 Field of view Field of View the width of your view as an angle with its apex at your viewpoint and the ends at the sides of the view Relates to the lens size 28mm wide angled lens 75 o 50mm normal lens 40 o 85mm long focus 24 o 3ds max v7

3D Modelling Tools 8 Creating cameras Target Free 3ds max v7

3D Modelling Tools 9 Free v. target A Free camera has a single icon to animate The Target camera has two the target the camera You can switch between camera types, changing a Free camera to a Target and back again

3D Modelling Tools 10 Camera view Make the viewport active then press C key The Viewport navigation controls change Different controls for cameras than for the Perspective viewport Dolly, pan, orbit

3D Modelling Tools 11 Free camera? Try positioning a fre camera……. Use a Target first and then modify it to a Free 3ds max v7

3D Modelling Tools 12 Moving cameras 1 Pan Rotates the target about the camera Tilt or orbit Rotates a camera about the target 3ds max v7

3D Modelling Tools 13 Moving cameras 2 Dolly Moves the camera and/or its target along the camera's main axis Truck Moves the camera parallel to the view plane 3ds max v7

3D Modelling Tools 14 Animating a camera Following a moving object Moving a camera along a track Panning Orbiting Zooming Creating Animated Cutaway Views You can animate the creation of a cutaway view by animating the location of the near or far clipping planes, or both. 3ds max v7

3D Modelling Tools 15 Following a moving object The Look-At constraint makes the object replace the camera’s target or Link a target camera’s target to the object 3ds max v7

3D Modelling Tools 16 Moving a Camera Along a Path Create architectural walkthroughs Car rides If the camera must bank or tilt close to the vertical (as on a roller coaster), use a free camera Assign the Path constraint directly to the camera object The camera follows the path, and you can adjust its point of view by adding pans or rotate transforms This is comparable to filming with a hand-held camera. For a target camera, link both the camera and its target to a dummy object Assign the path constraint to the dummy object This is comparable to mounting the camera on a tripod on a dolly 3ds max v7

3D Modelling Tools 17 Panning You can animate the pan of any camera very easily by following these steps: Select the camera Activate the Camera viewport Turn on the Auto Key button and advance the time slider to any frame Use the Pan button (in the viewport navigation tools) and pan 3ds max v7

3D Modelling Tools 18 Camera orbit Select the camera Activate the Camera viewport Turn on the Auto Key button and advance the time slider to any frame Use the Orbit button (in the viewport navigation tools) and orbit The target camera revolves around its target The Free camera revolves around its target distance 3ds max v7

3D Modelling Tools 19 Zooming Zooming moves toward or away from the camera’s subject matter by changing the focal length of the lens It differs from dollying, which physically moves the camera but leaves the focal length unchanged 3ds max v7

3D Modelling Tools 20 Portfolio 8 Use Portfolio 7 Add a target camera to your model to follow the car Add a free camera to your car to show the driver’s view Produce an A4 sheet with 8 small jpegs showing the view from the 2 cameras with the car at different positions on the track

3D Modelling Tools 21 Questions List and describe three different methods of animating a camera and recommend one for a walk through of a model List and describe two different camera types, give and justify a choice of one for use with an avatar in a game
