A 100-90, B 89-80, C 79-70, D 69-60, F <59. Incomplete grades will not be given unless there are documented medical or family reasons. Failure to complete assignments for any other reason will result in a drop in your final grade.
Attendance Policy: Each meeting of a class is considered a session. Attendance is taken at the beginning of each class session.

  • Students arriving after the 1:30pm start time for any class session are considered tardy. Three tardies equals one unexcused absence.

  • Students who do not return to class after break or who leave early without instructor permission may be counted absent.

  • Missing a class session will result in the reduction of the final grade.

  • Three unexcused absences equal failure in the course.

  • An absence may be excused if there is a medical reason, family emergency or extenuating circumstances beyond the student’s control. The final determination of whether an absence will be excused is left to the discretion of the student's instructor.


Academic Honesty (Plagiarism): Plagiarism and cheating are serious offenses that erode the academic environment. The University condones no form of plagiarism—defined as the use of another’s words, ideas, visual or verbal material as one’s own without proper permission or citation. Students should make sure they have a clear understanding of this important issue and how it applies to both Liberal Arts and studio classes.

Students who violate the standards of academic honesty face serious disciplinary consequences, including letters documenting the incident in their permanent record, immediate course failure and/or dismissal from the University.


Deletion/Destruction of Student Work: The deletion or destruction of digital files, another student’s artwork or University property is considered a serious offense. All students must refrain from altering work that does not belong to them, regardless of the date the piece was created or location. Students who violate this policy face serious disciplinary consequences.
Disability Accommodation: Northeastern University strives to provide academic accommodations to students with documented disabilities.  Accommodations are approved by the Disability Resource Center (20 Dodge Hall; www.drc.neu.edu).  Students need to register with the DRC and bring their instructors a letter from that office stating approved accommodations.  If you will be requesting accommodations in this class, please let me know as soon as possible to avoid delays.

Character Design for Animation WEEK 1 TUMBLR BLOG

You are required to submit homework each week via your Tumblr blog, due each Monday 10pm. Posts must include: (1) text (your name and a description) AND (2) either images or video, depending on the assignment. Please save images as 72ppi JPEGs before uploading. You are encouraged to post drafts earlier, and often!


Please read the other blogs in your class each week, and offer constructive responses!
If you already have a Tumblr account from a previous class, please use it here, but don’t use your personal Tumblr account--you are creating a professional record of your work.
NEW TUMBLR ACCOUNT SETUP STEPS

(for more tips, see http://www.wikihow.com/Use-Tumblr):


1. CREATE A TUMBLR ACCOUNT AND A BLOG: Go to Tumblr.com and create a new account with your preferred personal email (not a school email, so you can keep using it after graduation). If you do not yet have a non-school email, sign up first with gmail.com.
2. SETTINGS: Confirm your account with the email they send you, then log into your new Tumblr account and make the following changes to your settings:

a. FOLLOW THE TEACHER AND CLASSMATES:



  • On your main page, in the right-side menu, choose "Following."

  • Follow the teacher blog “Darmatage.” Find the "Staff" listing and hit [Unfollow].

  • Share your Tumblr handle with your classmates and follow each other.

b. REMOVE RANDOM POSTS (option may take time to be available on your account):

  • Hit the "Settings" gear and in the left-side menu choose "Dashboard."

  • Uncheck "Add Explore posts to my Dashboard ("You'll see posts from popular blogs that you don't follow.)". Hit [Save].

c. ALLOW RESPONSES:

  • Hit the "Settings" gear and on the left-side menu choose the bottom blog option.

  • At "Replies" check on both "Allow replies from people you follow." and "Allow replies from people following you for more than two weeks." Hit [Save].

d. SET NAME AND AVATAR:

  • Create a square image of yourself, 256x256, 72ppi.

  • Hit the "Settings" gear and on the left-side menu choose the bottom blog option.

  • At the top, hit [Change Avatar] and choose your square image.

  • To change your name from "Untitled", Click "Customize" in the theme section. Change the title in the Title field on the left.

e. CHOOSE A THEME WITH DATES:

  • Hit the "Settings" gear and on the left-side menu choose the bottom blog option.

  • Click "Customize" in the theme section, and choose a simple theme that includes dates. I recommend "Clean Read by Sparo," "Inkhorn," "Vacant," etc.

f. CREATE A TEST POST:

  • Back in the Dashboard, choose a text post (the most robust—you can still include images or video) and post your initial story ideas!

Normals:

  • Soften Edge = hit on one or more edges for light to move smoothly between adjacent faces.

  • Harden Edge = hit on one or more edges to form a hard line between make adjacent faces.

  • Reverse = select face and flip the normal

  • Conform =select around all faces to make all normal face the same direction


CLEAN UP: Always Edit/Delete By Type/ History & Modify/Freeze Transforms before saving your work.

PIVOT CHANGING: Modify/Center Pivot. Hold down [d] to move the pivot by hand.

PARENTING: [p] = parent selected objects to the last selected. [Shift]+[p] = break parenting.

MAYA TEXTURES:

Window/RenderingEditor/Hypershade to open material editor. Primarily used to apply textures to objects, can also be used for node-based programming



  • Use Lambert for Reference images and Blinn for object textures (includes specularity, connect to Specular Color channel). For opacity work to render in Mental Ray, include it as an empty background in the color PNG (and may need Lambert for ground Gradient).

  • DoubleClick new material to view properties in Attribute Editor. Click checker-square to add File node, then on folder icon to add bitmap (PNG/JPG).

  • NOTE: Maya only stores a pointer to bitmap; bring the bitmap file in a subfolder when moving a Maya file’s project folder. May still need to re-Set the Project and reconnect a bitmap by hand.

Setting the Project: File/Set Project to choose the project folder.
Menu Create UVs/Planar Map option box: choose projection axis based on selected faces: Z = front, X = side, Y = top or bottom. Hit [Apply] and hit red “T” to access special UV move/ rotate/scale. See transforms available in UV Texture Editor (bottom UVs default reversed: scale UVs “into” itself).
Window/UV Texture Editor to open the 2D “UVW” interface for any selected object. Primarily used for managing location of each surface part on a texture square, can also be used for selecting object parts.

  • Select UVs to move/rotate/scale. Select 1 UV, [Cmd]+RightClick “To Shell” for all attached UVs. Rotate by hand or use quarter-turn buttons on toolbar (circle arrow icons).

  • Select edge to Separate UVs ( scissor icon) or Move & Sew UVs (catty-cornered to scissors).

  • Export UVs to Photoshop: UV Texture Editor Polygons menu/UV Snapshot. Set size (2048x2048) and browse for name/location. Be sure selection is in Object Mode (not a component), hit [OK].


Render The Current Frame: Clapboard icon on Module bar. 3rd icon is Render Settings. In render view, hit Keep Image square to compare renders, or select in view and hit Render Region icon.
MAYA TOON SHADING:
"Surfacing" is the work to manage lights and textures to create a specific look and feel for a 3D render. In this class we will use Toon Shading to create a non-CG appearance and to integrate well with 2D VFX.
VIDEO TUTORIAL: http://www.cgmeetup.net/home/maya-toon-shading-tutorial/

SUMMARY: Use a 2-Tone Ramp Toon Shader that follows the light angle.

STEPS

(Use a complex shape to practice: a character or a Create/Polygons/Helix, hit [3] to smooth):



  1. In the Toon shelf select the “Light Angle Two Tone” SHADER (2nd from left). Open the Window/Rendering Editor/Hypershade and middle-mouse drag the new Toon Shader (bright white, labelled “LightAngle”) onto your 3D object.

  2. You must add a LIGHT to see results: From the Render shelf select the Spotlight. Pay attention to intensity so it does not blow out your Shader. Apply a target (select and hit [T] or add an empty node and an aim constraint (0,0,-1)).

  3. Double-click the Toon Shader to view its parameters in the Attribute Editor. In the Shader attributes slide the falloff bar to choose how much of each color will be present, and click on the squares on each side to change the color or on the circles to click on the checkered square and add bitmap/PNG nodes. To get different colors on different parts of your model, you can either:

  1. Unwrap the entire model into the same 0-1 space, paint detailed textures and export both light and dark versions as PNGs to apply to the right and left falloff options (best method!) or

  2. apply a different Toon Shader to each area of the model by selecting the polys and applying (one for skin, one for hair, one for shirt, etc). Not recommended because it means much less rich surfaces than the painted option above.

Character Design for Animation MUDBOX KEYBOARD SHORTCUTS

Here is an introduction to keyboard shortcuts and tools in Mudbox.

.

KEYBOARD SHORTCUTS: http://bit.ly/1NhpZfb


  • Tools Properties: Size=[b]+LMB, Strength=[m]+LMB, Mirror=[Shift]+[Alt/Option]+[x] / [y] / [z]

  • Focus=[F], Frame All=[A], Wireframe=[W], Undo [Ctrl/Cmd]+[z] Redo [Shift]+[z]

  • CAMERA: Rotate=[alt/option]+LMB, Pan=[alt/option]+MMB, Zoom=[alt/option]+RMB

  • Add SubD Level=[Shift]+[d], Step up/down SubD levels=[Page Up]/[Page Down]

  • Toggle Smooth=[Shift], Invert Sculpting Tool=[Ctrl]

  • Invert Freeze=[Shift]+[i] Unfreeze All =[Shift]+[u]

  • First nine Sculpting tools = 1-9 on the keyboard:

  • (1) Sculpt (2) Smooth (3) Grab (4) Pinch (5) Flatten (6) Foamy (7) Spray (8) Repeat (9) Imprint


BASICS:

  • Menu/Create/Sphere. RightClick in scene, turn off “Grid” and “Gradient” in context menus.

  • Select object in Scene or Object List to transform.

  • Add a Layer: click on Layer tab, or RightClick on Layers Menu to choose “New Layer”.

  • DoubleClick to change layer name.

  • Shift+[D] to subdivide (resolution flash in upperRight HUD, see in lowerLeft Status Bar).

  • [Page Up]/[Page Down] to view geometry SubD Levels.

NOTE: Once you start to sculpt, that Layer is locked to that SubD Level; you can add more SubD Levels, but to sculpt at them you need to add more Layers.

  • Use SubD level 3 for large shape changes, level 5 for adding medium details.

  • Select the Layer to make it active.

  • To Draw Guidelines, use Knife or reverse-Bulge tool [Ctrl].

  • Bulge and Grab tools to pull out forms, Pinch tool to accentuate edges.

  • Wax tool to add to forms. Foamy Tool to add finer fine sculpting, like nostrils.

  • Fill tool to make a surface in a depression, for modeling upon.

  • Hold [Shift] to toggle to Smooth tool while using any other.

  • Use Pinch tool to pull tighter any details made with Bulge tool. For seams, reverse Bulge [Ctrl] and then Pinch. Use property “Steady Stroke”.

  • An “extrude” is a freeze/invert/grab: In new Layer and SubD Level: select Layer, select Freeze tool at 100% strength, paint shape to be “extruded.” Hit [Shift]+[i] to invert Freeze so everything EXCEPT the painted shape is frozen. Use Bulge or Grab tool to pull out the form. To turn off all Freeze, hit [Shift] +[W]. Use Flatten tool to flatten top of “extrude.”

BEST SCULPTING PRACTICES (Textbook, p47):



  • Rough-in large forms first at lowest possible level that holds the form, add details later at higher levels (work general to specific).

  • When building up forms, blend into the surrounding area with the Smooth tool.

  • Organize reference materials, save often, save incremental files.

  • Rotate around model often. Move scene light [L]+MiddleMouse to see details.

  • View model with different materials. Try lighter materials to bring out details.

Character Design for Animators Notes on Clean 3D Modeling

The following are critical considerations for creating strong 3D Polygon Models in Maya:


TERMS:

Polygon: A triangle unit for building 3D forms. 3ds max mistakenly calls this a “face.”

Normal: The polygon facing direction, represented by a perpendicular arrow (normally invisible).

Modular: Geometry with a consistent, unbroken surface.
HYGIENIC (Clean) MODELING: “Unclean” geometry is where the model is no longer Modular. When geometry is unclean its surface can display strange shadows, change shape unpredictably when animated, and break when advanced techniques like Boolean are applied. Unclean geometry includes:

  • Interior Geometry: All models should be a hollow shell. Polygons crossing through your shell, sometimes with vertices attached both to one side and the opposite side, must be deleted. Another example is if two vertices on opposite sides of a form get collapsed.

  • Duplicate Vertices: What appears to be a single vertex is actually two or more in the same space. These must be merged.

  • Coplanar Geometry: Two polygons occupying the same space, sometimes with Normals facing in opposite directions. One of these polygons must be deleted, or bad “flickering” will appear in the render.

  • T-Geometry: Planes that intersect without being connected by vertices (essentially, one object just stuck into another and attached, without being connected to create a consistent, modular surface). Both objects can be Cut at their intersections, the internal geometry deleted, and the matching vertices welded, or they can be detached and Booleaned into each other.


WASTED GEOMETRY: Vertices sitting on straight lines which do not contribute to the form represent wasted polygons. In both real-time games and pre-rendered film projects these wasted polygons cost money and resources, and must be eliminated through collapsing and snap-merging vertices.
AVOID LONG POLYGONS: Long polygons will frequently cause issues with lighting and shadows. Most rendering systems calculate lighting by the location of vertices, and if these are too far apart the space between them will have difficulty lighting properly. The solution is NOT to add wasted vertices along the surface; instead, design your forms with more variation and detail.
GOOD CURVES AND SILHOUETTES: Curves need enough polygons to appear smooth. Consider added detail to make the silhouette interesting, such as clothing breaks.
ORGANIC MODELING: For all characters, the following three principles must be applied to create forms which will animate smoothly:

  • Even Tessellation: Be sure to evenly space the divisions on all the parts of the body, so that the upper arms, lower arms, upper and lower leg, and torso have roughly even spacing. Joints and the face will have higher tessellation, but should still be internally even.

  • Quads: Work toward only 4-sided shapes everywhere (two triangular polygons). Avoid triangles where possible, and absolutely be sure to cut down all shapes more than 4 sides (N-gons)

  • Edge loops: Cut lines on the body to enhance animation by following muscle forms: straight circles around the limbs and torso, concentric circles around the mouth and eyes.


ANGLES: Most outside edges should be Beveled to not appear sharp. Avoid acute angles (<90 degrees) and adjust interior extruded edges to make them obtuse (>90) for better visibility and appeal.
SOFTEN/HARDEN: Use these buttons under the “Normals” menu to remove hardness from edges and create unified surfaces on big forms, and to define the difference between material forms. On a character, for example, all the skin should be one form, the pants one, the shirt one, the belt one, etc.
