3D Modeling Challenge

Hello Students,
Your project goal is to model an object with Autodesk Maya that is complete with some details materials and/or textures. 3D modeling is becoming an integral part of digital media studies and is used in everything from cinematic CGI, marketing, music videos, video games, prototype development and of course the new hot trend of 3D printing. Strong modeling skills can fit you into a high demand job market in many different industries.

Modeling Challenge:

Start small and work with simple objects and primitives to "assemble" a real world, or otherwise... object... science fiction is fair game. Use your imagination...
  1. Read through the Maya User Guide sections on POLYGON and NURB modeling and try out as many methods and techniques as possible. Having a good understanding of these areas are key to being able to make and create unique shapes that are the sum of any object.
  2. Follow the tutorial videos on Box Modeling and Smoothing provided by the instructor. Watch, pause and try the steps to create an example model such as the claw hammer. (DOWNLOAD FROM NAS)
  3. Decide on an object to model and begin by creating the simplest part of the objects and move up to adding more complexity and detail as it takes shape. Utilize both Polygon and NURBS when needed. Having a reference object is a great idea, or having a gallery of images to reference can help too. If you are not confident with your modeling skills you could look up a tutorial and use that to accomplish your modeling.
  4. When your object is complete begin creating materials and textures for it with the Hypershade window. Complex materials can be mapped onto an object by using the UV Texture Editor and creating a Photoshop Network file, this is how much of the texturing is done in video games and cinematic CGI.
  5. Create a camera for your scene and set up Arnold with a Skydome that uses a HDR Light Probe for extra realism. Use the Arnold setup from our Cornell Box project.
  6. Test your renders and adjust as needed for best results.
  7. Render multiple views of your model and time permitting create a 360 degree rotation animation to accompany your final renders and post to your blog when complete. 
  8. Render in 1920 HD resolution.
  9. Post your claw hammer, practice objects and your final rendered model to your blog when complete....

The Cornell Box and rendering "Radiosity" with Arnold

For this project you will be getting more familiar with the workflow and methods in using Autdodesk's Maya to create a 3D scene with objects, lighting, a camera and textures. You will then render this scene and adjust quality, then render an animation to learn the basics of keyframing and render settings as well.



Cornell Box Project: Lights, Camera, Action!

History of the Cornell Box: The Cornell Program of Computer Graphics has become best known for its research on physically based rendering. They believe that computer graphic simulations will never become predictive of reality unless we correctly model the physics of light reflection and energy propagation within physical environments. The Cornell Box experiments have come to symbolize our approach to physically based rendering, it is a simply physical environment for which they have measured lighting, geometry and material reflectance properties. Digital, or synthetic images of this environment are created and compared to confirm accuracy of our simulations with 3D software.

A photograph of the original physical Cornell Box.
For this project you will create a scene to simulate the Cornell Box. You will create an environment, objects, textures, a light source and explore the rendering software available in Maya to try and recreate the photo we see above.

A Cornell Box created by Seth Wilson using Maya. This scene contains the famous Utah Teapot. Textures are made with blinn, lambert, phong, the light is a point light using depth map shadows, the scene was rendered with Mental Ray
Cornell Box Project Part 1: Creating The Scene
  1. Open Maya and create a new scene
  2. Create a cube that is perfectly square, turn on Component Selection and delete the front face of the cube so you have a box
  3. Create 2 more cubes and scale/stretch and move them into position to act as your pedestals in the scene
  4. Create a cylinder, sphere, triange or cone and other primitive objects and arrange them in your scene as above using the move and scale tools
  5. Create a cube and flatten it with the scale tool, position it on the roof of your box to act as a "light" later on
  6. Open your Hypershade window (Window Menu/Rendering Editors/Hypershade) and create 2 materials using the Lambert material, make one have a red color and one green. Double click the material to see the material settings
  7. Select your box and turn on Component Selection, select the right face inside the box and apply your red Lamber material, then select the other side and apply the green Lambert material. Select the face first, then right-click on your Material and choose "Assign Material to Selection" to apply it to that face
  8. Create a point light and move it to the top of the inside of your box using the move tool. Turn on "Use All Lights" in your view options to see it affect your scene
  9. Render your scene and check the quality, if your light is illuminating the scene your are doing great!
  10. Close your Render Window
  11. Open your Hypershade window again and create different materials for each of the objects in your scene, try a blinn, a lambert, a phong and try creating a 2D texture such as a checkerboard patter
  12. Select an object first, then right-click on your Material and choose "Assign Material to Selection" to apply it to that object
  13. To make your roof light cube glow, create a blinn material and set it to have a white color, set the illumination to half way to make the object bright, scroll down to the Special Effects section of the blinn material and set the Glow Intensity to 0.010 and apply the blinn to your roof light cube
  14. Under the Create menu, create a Camera
  15. Change your view point to see through your camera, it will be called Camera1 and it is under the Perspective submenu in the Panel menu of your view window
  16. Center your camera to view your scene straight on
  17. Click the render button to see what you get! Compare with your classmates results


Cornell Box Project Part 2: Render Settings

  1. Use the Arnold renderer and Arnold material pack to add materials to your scene.
  2. Edit your render quality, render and adjust for best results.
  3. Use Arnold Lights for best results in your scene



Cornell Box Project Part 3: Animate Your Camera

  1. Spend some time fine tuning your render and scene to make sure it looks it's best, adjust lights, textures and positioning before proceeding
  2. Bring up your camera view and center it on your box with the camera move tools
  3. In your time line enter 120 frames into the duration field and drag your time slider out so all frames are visible in your timeline
  4. On frame 1, with your camera selected (you can select it by clicking on it in the outliner or another view window) press the "S" key to create a keyframe. A red line will appear on your timeline to show that a keyframe has been created
  5. Slide your time line down to frame 120 and then use the camera move tools to zoom your camera into your scene, add a slight pan to your camera move as well to add a little dimension.
  6. With the camera still selected press the "S" key to make a second keyframe on your timeline
  7. Press the play button to preview your camera move and adjust if needed, you should have a nice slow movement like the one above
Cornell Box Project Part 4: Set Up Your Project Folder

  1. Rendering an animation requires setting up a project folder which contains your maya file and a set of folders for containing all the required materials, files and assets in a maya project. Your project may not utilize these resources but maya needs this file/folder structure anyway and it is not possible to render animated frames without them
  2. Close Maya and make a new project folder on your computer, place your cornell box maya file inside it and open the file by double-clicking on it.
  3. After your file is open go to the File Menu / Projects / New and your will see the project set up dialog box
  4. In the Name Field type in a name for your project, this should be something like CornellBox_Project
  5. Verify that the location is correct, click browse and navigate to your project folder if needed
  6. On the bottom of the dialog box, click Use Defaults and you will see the folders names being created
  7. Click Accept to complete
Cornell Box Project Part 5: Render Your Animation

  1. With your maya file still open, go to the Window Menu / Rendering Editors / Render Settings
  2. In the Common Tab set up your options for your animation. under File Output set the Frame/Animation ext to name#.ext
  3. Set Image Format to Maya IFF
  4. Scroll down to Frame Range and enter your start and end frames, start should be set to 1 and end should be set to 120
  5. Scroll down and set Renderable Camera to Camera1, your animated camera
  6. Choose your image size from the preset pull down menu, I used a 1K Square image for my own example above
  7. Close the Render Settings window
  8. Press and hold the Space Bar to bring up the Maya Marker Menu, click on the Render Menu and choose Batch Render, Maya will now begin to render your animation, this may take awhile depending on how long it takes to render each frame
  9. When the render is done maya will give a message that says Render Completed in the Mel Script window
  10. When your render is done open your project folder and look in the images folder to see your frames
  11. Open the Fcheck program (located in the autodesk/maya folder in your applications folder) and load the IFF file sequence you just created to check for quality
  12. You may use Fcheck to export a quicktime file, or you can use a program like After Effects to create a video file from your animated sequence
  13. Turn in a quicktime file of your animation and pat yourself on the back! Woo! But wait, your not done!!!!

Getting Oriented to the 3D World of Maya

Hello Students,
Today we begin a new project in using a 3D program to create computer generated imagery. We will be using Autodesk's Maya, a cutting edge program widely used in the entertainment industry. We will begin with the basics and move on to more complex projects such as creating 3D models, and adding lights, textures and cameras and animating them and move on to more complex tasks such as merging video and 3D together with motion tracking.

Tasks: Follow the tutorials below to create the model below:

Maya Basics:
Find and launch Maya on your computer, then open each of the links below if safari. Read through each page of the 3 lessons below and try out the steps for your self in Maya. These lessons will teach you how to use the Maya interface, how to create and manipulate objects and how to control your objects and your view of your objects. Create something with the skills you develop here and save the file as "mayabasics_yourname.ma" and copy it to the external drive to turn it in.

Parallax Effect (Aka: Ken Burns Effect) Project

Hello Students,
AE has some amazing capabilities such as the ability to animate in a 3D space using 2D objects. This method is referred to as 2.5D. This method was made popular by the famous documentarian Ken Burns. The same technique is also referred to as a Parralax effect, which is a technique that shows objects that move against each other from the foreground to the background to create an illusion of depth. This is used in cinema, cartoons, video games and can even be created using HTML5 to add an creative and eye catching feature to websites.



Parallax Project (Aka: Ken Burns Project)
  • Find or take a photograph that you can animate using the 2.5D/Parallax method, this photo should be high resolution, include good amounts of detail and have a good balance of foreground and background, as a rule your photo should have at least twice the resolution of your composition
  • Open your photo in photoshop and create layers for your animation, use selection tools to isolate your foreground subject from the background. If you take your own photo make sure to take a version with no subject so you have a clean background to use and you can skip the next step
  • On the background layer in photoshop use the "fill with content aware" and touch up area with the clone tool where you need to cover up
  • Save your photo as a Photoshop document with your layers ready and import it into After Effects
  • Make sure to click "import as composition" to preserve your layers for use in AE
  • Create a new composition in AE for your project
  • Open your PSD composition and Copy/Paste the layers into your main composition
  • Enable the 3D button for all layers
  • Create a 3D camera for your scene
  • Use the camera manipulator tool to zoom into your Photograph layers and frame your "shot"
  • Using the move tool, select your subject layer and drag it on the Z axis towards the camera a little bit
  • Move the background away and scale up if needed
  • Use the camera manipulator tool to explore the range of motion that looks good, create a set of keyframes for the camera position, then move the playback head to the end of your composition and move your camera inwards and to the right or left in a subtle movement
  • Preview your animation to get the camera/layer position just right
  • Use Ease-In on your last set of keyframes to slow down the motion
  • Add a vignette, tint, depth-of-field effect or other enhancements for full credit
  • Having trouble? Try googling "parallax effect in AE" and look for a tutorial video, there are some very good and easy to follow tutorials online
Due on tuesday, have fun! - Mr.W
