COURSE DESCRIPTION

This course introduces aspects and methods for achieving high-quality 3D models both organic and inorganic. Major emphasis of this class will be put on the creative output of the student via the tools learned and projects assigned. Moreover, the course aims toward the comprehensive use of techniques in Maya to create meaningful 3D sculptures and environments with expressive content. The class will be structured around increasingly challenging projects around practical topics, and a final focusing on the human head. Lectures will focus on the tools and principles of surface construction as well as characteristics involving materials, textures, lighting, and more. Related topics may include intro to rendering: HDRI rendering, Final Gather, ambient occlusion, radiocity, and 2D rendering techniques.

PREREQUISITES

ART 380, Computer Graphics I

INSTRUCTIONAL METHODS

Class lectures, in-class assignments, and project related demonstrations will be provided from original or researched content. Supplemental homework assignments, specific tutorials from published sources will be given. Most of these assignments are, of course, to be done exclusively outside the hours of class time.

The expecation is 3 to 6 hours per week working outside of class on project assignments and homework. Lab hours will be posted.
There are numerous books and online tutorials on 3D modeling. I have listed recommendations of texts and URLs for further study. I will also distribute, handouts, images, and other reference materials to supplement your studies.

EDUCATIONAL OUTCOMES

upon completing this course the student should be able to:

-be able to think, plan and work creatively and comfortably with 3D modeling tools, and display expressive choices and technical proficiency.

-apply industry standard modeling techniques of correct quad-based topology

-posses a versatility in different modeling strategies including Polygon, NURBS, and Subdivisional

-create high quality texture maps with UV layout coordinates with precision on models

-create both high quality inorganic and organic referenced models, including the ability to create anatomical models based on reference which are "on-model".

-predict and build the topology (muscle)flow for characters which anticipate future pipeline events such as blend shape animation.

-obtain a comfort with the node-based structure and inter-dependancy in Maya; and have a strong knowledge of its context and workflow for creating models.

PROJECT #2 (MIDTERM) is due

FINAL PROJECT is assigned: CREATE A 3D MODEL OF YOUR OWN HEAD.. create a 3D head closely based on photo-references to match as closely as possible to refererce. They modify the head, style, look, or appearance of the head that provides an alter-ego or a much different yet perhaps hidden side of yourself. (due Finals Week)Proposal and sketches for FINAL PROJECT assigned (due Week 7)

Look Over Midterm Projects, Class Critique

BELOW IS THE CRITERIA FOR THE Final Project

1)The standard and quality of model, textures, lighting must be very high (matching the most rigorous evaluation grading cirteria (in blue below) the "head" must have proper topolody, and UV texutre maps of color, bump, specularity maps, etc, where necessary.

2)The film should reflect a SINCERE ATTEMPT BY THE STUDENT TO COMMUNICATE an imaginative new identity(potential)through the model, whether that be a specialized object, environment, world or character.

3)The piece must have an idea of what target viewer, group, or audience would this piece be produced for.

4)You must have at least FOUR, 3K renders of your final model, with high-end texture, lighting, etc. UV texture mapping is expected on at least one or more of your surfaces. Either realistic or specialized lighting is expected in your scene which clearly defines a strategic lighting situation.

5)You must show efficient level of modeling skill in Polygon, NURBS and/or SubDs

6)The model should give the impression of STYLE, a graphic or aesthetic strategy used by the artist. The design/sketch approval phase will dictate most of this.

7)You must follow the file tree specifications when turning in all of the Final Project Content

FINAL PROJECT to be completed and turned in on designated due date on Finals Day of the 11th week. Student presentations will be prepared for Finals, where classmate critique and discussion will end the course.

Homework assignments will be given points based on accurate completion of assigned readings, assignments and tutorials.

Projects 1, 2(Midterm) and the Final project will graded based on these criteria:

*Quality and Technical Competency the Model

*Staging and Strength of the Design

*Quality of Lighting

*Appeal and treatment of Surfaces

*Creativity and Content

Each given an equal weight of 20%, to compose your grade for each project

It is, of course, the responsibility of each to ensure his/her work in completed an handed in on due dates (see below)

Critical review of your work will provide the source most assessments. Participation grade includes the extent and quality of the participation in the critiques, presentation of projects and positive interaction with classmates and professional approach toward the class. Students requiring any kind of special assistance should speak with the instructor at their earliest convenience.

Class Participation: % 10

Homework %10

Project #1 %15

Project #2 (Midterm) %25

Final Project %40

GRADE SCALE: A 90%-100%B 80%-89%C 70%-79%D 60%-69%F Below 60%

The learning curve in Maya is steep, missing even one class is enough to put you significantly behind. Regular class attendance in mandatory. Class attendance is also part of your class participation grade. Arriving on time is equally important. You would be fired in a job you do not show up on time for. The expectation here is similar. You will be considered absent one class period for every three tardies. (more than five minutes late)

Missing 5 classes, consecutively or not) is an AUTOMATIC FAILURE for the class.

Expect to spend from three to six hours a week on your working outside of class. Lab hours will be available and posted by the end of the first week.

Students are responsible for any material missed due to tardiness or absence. Readings, and assignments, and projects are expected at the beginning of class on their due dates.

Late submissions will be lowered one grade per class day late.

student may be able to re-submit any assignment for an improvement grade. The policies are specific to each assignment. Check specific project descriptions for more details.

Late assignments, or absences due only to emergency or illness may be granted leniency only per the instructor's discretion.

Extra Credit:

Students may be able to re-submit any assignment for an improvement points as long as that assignment was turned in the original due date. The policies are specific to each assignment. Check specific project descriptions for more details.

Other opportunities for extra credit are possible involving visiting realted exhibits, films, museums, specific research, attending relevant shows or conferences, or related study, etc. Such points are limited and per the instructor's discretion
