Outline
● Steps for designing a 3D game
● Blender – a free 3D authoring and animation tool
● Java MonkeyEngine – for Java based game development

Designing a 3D game
● For what purpose and target
group
● Available personal resources
(me) and time (8 h)
● Level of detail
● Complexity of the Game logic
● Complexity of the graphical
user interface

Character Design
● What kind of 3D Models ● Textures
● Animations

Static Interior
● For the right feeling
● Modeling complexity

Board texture

Modeling with Blender
● 3D Authoring and Animation
● Free available on Blender.org
● Large community providing
tutorials, models and help

Board Preparation
● Name and place coins
● Create board texture
● Assign textures for coins
and board

Character Modeling
● Form body and arms
● Beautify body
● Build Skeleton

Texture preparation
● set seams to unwrap skin
● Skin painting

Animation Setup
● Define Keyframes
● Adjust Positions
● Use inverse kinematics
