The Game Development Process Game Art Design and Production Artistic Courses • AR 1100. ESSENTIALS OF ART. This course provides an introduction to the basic principles of two and three-dimensional visual organization. The course focuses on graphic expression, idea development, and visual literacy. Students will be expected to master basic rendering skills, perspective drawing, concept art, and storyboarding through both traditional and computer-based tools. • AR 1101. DIGITAL IMAGING AND COMPUTER ART. This course focuses on the methods, procedures and techniques of creating and manipulating images through electronic and digital means. Students will develop an understanding of image alteration. Topics may include color theory, displays, modeling, shading, and visual perception. • AR 3000. THE ART OF ANIMATION. This course examines the fundamentals of computer generated 2D and 3D modeling and animation as they apply to creating believable characters and environments. Students will learn skeletal animation and traditional polygonal animation, giving weight and personality to characters through movement, environmental lighting, and changing mood and emotion. Students will be expected to master the tools of 3D modeling and skinning, and scripting of behaviors. (Ask: Who’s taken? IMGD-Art majors?) 1
Introduction • “The computer artist is modern-day alchemist” – ( Creating the Art of the Game , by Matthew Omernick) – Turn polygons and pixels into wondrous worlds • Sources of inspiration – Playing games! (How can make fun game if not having fun yourself?) – The real world (The real world is always more interesting than anything we can make up) Based on Foreword, Creating the Art of the Game , by Matthew Omernick Introduction: Remember the Constraints • Year 2098, Macrosoft will release FunStation 3000, 14 million terabytes of RAM, quantum-holographic drive with near infinite storage, processors at the speed of light – Game developers complain not fast enough • Game artists must be creative inside confines of technology – All disciplines: engineering, design, sound – But often constraints biggest on artist Based on Foreword, Creating the Art of the Game , by Matthew Omernick 2
Outline • The Pipeline • Concept Art • 2D Art – Animation, Tiles • 3D Art – Modeling, Texturing, Lighting What's a Pipeline? • In the pipeline – Informal . in the process of being developed, provided, or completed; in the works; under way. (Random House) • For our purposes – The sequence of operations required to move art assets from concept to the finished product • The Art Pipeline: – 2D: Concept, Creation, Conversion – 3D: Concept, Creation (Modeling,Texturing, Lighting), Conversion – Asset Management 3
Types of 2D Art • Created with tools: – User Interface (UI) – Sprites, Tiles, and other pixel art – Type and fonts • Need a pipeline: – Character art – Scenery / worlds – Characters – Animation – Video 2D Asset Creation 4
2D Pipeline – Concept (1 of 3) • Sketches – Napkin-style – Detailed design treatments – Prototypes “Napkin-style” Concept Art 5

2D Pipeline – Creation (2 of 3) • Commercial / third party tools: – Photoshop, The Gimp, sprite editors, HTML/browsers, Flash... • Homegrown tools – Specialized animation systems – Tools that simulate key game features (UI layout tool, etc) – The game engine Assets for a 2D animation (1 of 3) eberlein.org/euphoria 7

2D Pipeline – Conversion (3 of 3) • Putting the assets into the final form • File type conversion – PSD to TGA / JPG, for example – Compression – Collection (zip files, pak files, etc) • Testing in the game • Debug / fix 3D Asset Creation 9
3D Pipeline – Concept (1 of 4) • Sketches – Napkin-style – Detailed design treatments – Prototypes – Maquettes – Animation sketches / flipbooks – Mockup models – Texture mockups – Architectural layout 3D UI Prototype lostgarden.com 10
3D Pipeline – Creation (2 of 4) • Commercial / third party tools: – Photoshop, The Gimp, sprite editors, HTML/browsers, Flash... – 3D tools: 3D Studio Max, Maya, Lightwave, Blender • Homegrown tools – Specialized animation systems – Tools that simulate key game features (UI layout tool, etc) – The game engine – Exporters / plugins 3D Studio Max gamedev.net 11

3D Pipeline – Conversion (4 of 4) • Conversion – Export from modeling to custom formats – Putting the assets into the final form • File type conversion – PSD to TGA / JPG, for example – Compression – Collection (zip files, pak files, etc) • Testing in the game • Debug / fix Asset Management • How do you share the production process across time, space, and content creators? – Source code has many tools – "solved" – Data/Art is harder • Not easily merged • Dependencies not obvious • Relationships complex – Some commercial systems are trying – Typically a combination of: • Homegrown tools • Convention and process 15
Outline • The Pipeline • Concept Art (next) • 2D Art – Animation, Tiles • 3D Art – Modeling, Texturing, Lighting Why Not Just Prototype? • Even creating prototypes can be time consuming and expensive • Getting it right on the first try is unlikely • Revising instantiated work can be difficult Thus the need for some forethought !

What is a Better Way? Make decisions on paper, where changes and variations can be made quickly and easily. Art and organization by Paolo Piselli, http://www.piselli.com What is Concept Drawing? (1 of 2) • From illustration, but is a modern idea • Main goal to convey visual representation of a design, idea, and/or mood • Use in movies, comic books and computer games • Before it is put into the final product (or even prototype) Art and organization by Paolo Piselli, http://www.piselli.com 17
What is Concept Drawing? (2 of 2) It is not a full design, blueprint or specification. It is a partial design that gives enough detail to imply a full design. I MPLI ES Concept I m plem entation Art and organization by Paolo Piselli, http://www.piselli.com Who Is Involved? We can think of the process as a two-part system: The BOSS supplies the The ARTIST generates drawings constraints that the drawing based on the given constraints. needs to fill. Art and organization by Paolo Piselli, http://www.piselli.com 18
The BOSS (1 of 3) • Takes part in a higher-level design process with goals of its own Attract web-goers Sell more widgets Win an Oscar Art and organization by Paolo Piselli, http://www.piselli.com The BOSS (2 of 3) • Communicates constraints inherited from this higher-level process to the ARTIST We need a happy, purple dinosaur to sell more widgets! Happy Purple Dinosaur Art and organization by Paolo Piselli, http://www.piselli.com 19
The BOSS (3 of 3) • Evaluates the fitness of the ARTIST’s solutions based on various heuristics Market research says its good Wife likes it Magic 8-Ball says outlook not so good Art and organization by Paolo Piselli, http://www.piselli.com The ARTIST (1 of 4) • Generates drawings based on the given constraints We need a happy, purple dinosaur to sell more widgets!

The ARTIST (2 of 4) • Has expert knowledge of drawing materials and techniques Art and organization by Paolo Piselli, http://www.piselli.com The ARTIST (3 of 4) • Has aesthetic heuristics (acquired by studying style, design and master artwork) Art and organization by Paolo Piselli, http://www.piselli.com 21
The ARTIST (4 of 4) • May need to cache domain-specific knowledge (dinosaur anatomy, typical dress of a noblewoman in 13 th century England, etc.) Art and organization by Paolo Piselli, http://www.piselli.com A Space of Ideas (1 of 3) There is a space of drawings that potentially satisfy some set of constraints (could be from cache) (Space of Evil Lizard- Monsters) Art and organization by Paolo Piselli, http://www.piselli.com 22
A Space of Ideas (2 of 3) The ARTIST is capable of generating drawings that represent regions of this space. (Remember that because a concept drawing is not a full design, there is some range of designs that each drawing represents) Art and organization by Paolo Piselli, http://www.piselli.com A Space of Ideas (3 of 3) The BOSS provides the ARTIST with direction in searching this space for a solution that optimizes BOSS’s heuristics. My wife says it needs more armor! “Concepting” is like a hill-climbing search of the idea space! Art and organization by Paolo Piselli, http://www.piselli.com 23
