Maya Lighting and Rendering and Hierarchy assignment

Maya Assigment will be due on Friday, October 10th:

  1. Javascript: Two Lamps Slideshow of Examples: See the magnificent seven Maya Renders to help you understand the two lamps, baseball bat, wine glass assignment.

  2. Examples of a lamp made up off all Polygonal Cubes, except for the NURBS Cone that encloses the Spot Light. Also shows Textures on the floor, and having a side wall made up of a Polygonal Plane. Parent/Child hierarchy of 8 object: SIX Polygonal Cubes, ONE NURBS Cone, and ONE Spot Light. 5 different renderings, some with shadows. No Polygonal Cylinders in the LAMP. No NURBS Sphere in the lamp.

  3. How do you set a light to show SHADOWS in Maya? Here is a screen snapshot showing setting of shadows to ON. It is the Attribute Editor, not the Channel Box, to get to the Lights shadow setting. The screen snapshot was creating using the Paint program, not using Photoshop. The Windows Paint program comes with Windows and is still found in the Accessories group, even for Windows Vista.

    Leon and his pet, Earl-the-squirrel from the short animated movie Moongirl, with suitable allusions to another famous movie character, Mr. Staypuft.

  4. Three examples that light objects with Textures. Floor has a rainbow texture and the lamp cone has a checkerboard texture.

    Example One.
    Example Two.
    Example Three.

    Uploaded to example from Friday morning class:Oct3rd.jpg Saved as JPEG rendered scene. Notice the URL when you are looking at this Oct3rd.jpg JPEG image. Replace jacobson with your own UNI USER ID and you can look at your own jpeg from today's class. Oct3rd.jpg is NOT the same as oct3rd.jpg to the web server. The server is CaSe SeNsItIvE!

  5. This graphic was a handout in the last class in September (Monday 09/29). It is much improved and via the miracle of Photoshop colorfully shows you the Point Light, Spot Light, Render Current Frame, and Use All Lights command from the Lighting menu and which menus are part of FEMCDW and which are part of the Panel menus for the Top, Side, Front and Persp View Panels.
    VIP Note: It has been improved and enhanced since handed out in Monday, so be sure to look it over and pay attention to the PURPLE and RED relationships.

  6. First Email note about the assignment including some important tips about and your UNI web site URL, not to mention BICTION. Consume some ink and scratch paper (aka consume some pencil lead and notebook paper works too). Biction is nicer cause on INK and thINK and the fact that INK flows and understanding GROWS rhyme.

  7. VIP: Do NOT forget to go back and read the main web page! The PREREQUISITES and Further Information is listed there in a lower-case Roman Numerals itemized list.

  8. Create a Luxo Lamp like the one shown above using the Michael O'Rourke tutorial and my suggestions/improvements for it. Tutorial and in depth 810:088 email note and Class #15 review about the Nurbs Sphere, Polygon Cylinders, Nurbs Cone and the Spot Light. Discussion of parenting and Freeze too.

  9. Create a 2nd Luxo Lamp that uses Polygon Cubes instead of Polygon Cylinders for the arms. Have this 2nd Luxo Lamp have FOUR arms, instead of 3 arms. Each arm will be a long, thin CUBE instead of a cylinder. This will give you extra, extremely valuable practice with modeling of lamps and the hierarchy tutorial skills from the Michael O'Rourke tutorial.

  10. Your scene will have two lamps, each with its own Spot Light.

    Interesting aside about the Luxo Lamp and the history of 3D computer graphics. Lighting issue and the planning that shows up on storyboards. Animating lights. "little Luxo", the lamp with a personality that the animated camera helps to reveal, helps to shine forth. Michael O'Rourke famous, widely used book on 3D Computer Animation talks about "little Luxo".

  11. A wine glass will be in the scene. Position one of your lamps so it is illuminating the wine glass and casting a shadow.

  12. A baseball bat will be in the scene. Position the other lamp so it is illuminating the baseball bat and casting a shadow. The baseball bat will be created by the Revolve technique where you Revolve a Curve to create a Surface. It you revolve 360 degrees around an axis, it will be perfectly symmetrical:
    Create > CV Curve Tool    ( from the FEMCDW first six menus )
    Surfaces > Revolve | |    ( from the Surface menu set )
    We have done this in the lab before.  It will be done again in the
    lab on Friday and/or demonstrated in class on Monday.
    There is much more to learn about CV Curves and CVs, Edit Points and Hulls.

  13. Your scene will have two different Point Lights. Look at the two different shadows that the RED lamp in the rendered scene below is casting upon the YELLOW floor. Each shadow is cast by a differently positioned POINT Light object.

    The 2nd and 3rd JPEG images below were rendered BEFORE I added a 2nd Point Light to the scene. Thus, you only see one shadow cast by the Luxo Lamp.

  14. DARKEST SHADOW: The very dark shadow cast by the TURQOISE baseball bat (or bowling pin, if you like) is cast by the SPOT LIGHT, which is a child of the NURBS Cone and great, great, great grandchild of the Nurbs Sphere at the very base of that RED. Recall is is a parent-child hierarchy of 6 different objects (Nurbs Sphere, Poly Cylinder 1, Poly Cylinder 2, Poly Cylinder 3, Nurbs Cone and finally Spot Light).

  15. Your objects will be colored. Obviously, you will have a floor, probably a polygonal plane, that the two lamps and the baseball bat and the wine glass are sitting on.
