CreatingEfficientVR:ProjectManagement
Project ManagementDescription
● Project management includes techniques used to keep all 3D models, scripts, assets, etc. properly organized
Tips for Efficiency● Use source control ● Use cloud storage
Alternatives● Perforce● Mercurial
Preferred Tools ● Sourcetree/ Git● Dropbox
CreatingEfficientVR:3DModeling
3D ModelingDescription
● Process of developing a mathematical representation of any three-dimensional surface of an object via specialized software
Tips for Efficiency● Retopology - synergy between artistically-driven sculpting and
technically-minded poly-modeling● Reduce polygon count while maintaining a high quality model● Normal mapping
Alt to Blender● MAYA
3DS MAXSolid Works
Preferred Tool ● Blender (free)
CreatingEfficientVR:UVMapping
UV MappingDescription
● Projecting a 2D image to a 3D model's surface for texture mapping
Tips for Efficiency● Start with automatic UV layouts● Find areas where a seam would naturally appear
and mark it as a seam
Alt to Blender● MAYA
3DS MAXSolid Works
Preferred Tool ● Blender (free)
CreatingEfficientVR:Texturing
TexturingDescription
● Texturing is the process of applying an image to a 3D model
Tips for Efficiency● Procedurally generated
materials and textures created using Allegorithmic Substances drastically speed up the texturing process
Alt to Photoshop● GIMP● Substances
Preferred Tools ● Blender (free)● Photoshop
CreatingEfficientVR:Animation
AnimationDescription
● The process of bringing to life any that require movement: Objects, armatures (skeletons), meshes, particles, UI elements, etc.
Tips for Efficiency● Unity’s Mecanim system makes bone-based
animations easier to use● Mecanim can also be used as a visual state
machine
Other Tool Options● MAYA● 3DS MAX
Preferred Tools ● Blender (free)● Unity
CreatingEfficientVR:ImportandPrefabSet-up
Import & Set Up PrefabsDescription
● Prefabs are containers for 3D models, scripts, animations, etc.
● Virtual scenes consist of a collection of prefabs
Tips for Efficiency● Create editor scripts that minimize repeated work
(e.g. add a button for creating colliders)
Other Tool Options● Unreal
Preferred Tool ● Unity Game Engine
CreatingEfficientVR:DesignScenarios
Design ScenariosDescription
● Designing scenarios ties all the pieces together (e.g. 3D models, prefabs, simulation logic, etc.)
● Iterative testing is very important at this stage
Tips for Efficiency● Meet weekly with SMEs to ensure everything is
on track● Start with simple prototypes and build from
thereOther Tool Options
● UnrealPreferred Tool
● Unity Game Engine
CreatingEfficientVR:AudioEngineering
Audio EngineeringDescription
● Audio can add a lot of value to a simulation● Voice overs● Audio cues need to be triggered by scripts at
the correct time
Tips for Efficiency● Start with royalty-free sounds and edit as
necessary
Alt. to Audacity● Audition
Preferred Tool ● Audacity
CreatingEfficientVR:ConstructUIElements
Construct UI ElementsDescription
● User Interface (UI) elements include text, pop-ups, icons, graphical user elements, etc.
Tips for Efficiency● Ties in closely with system architecture● Align with SME feedback and Learning Outcomes● Graphic designers can provide insight
Other Tool Options● Unreal
Preferred Tools ● Unity Game Engine ● Photoshop
CreatingEfficientVR:Programming
ProgrammingDescription
● User interaction, user interface,state machines, etc.
Tips for Efficiency● Never duplicate code● Create a reusable architecture
Alternative● MonoDevelop
Preferred Tool ● Microsoft Visual
Studio
CreatingEfficientVR:QualityAssurance
Quality AssuranceDescription
● Iterative process of review, feedback, and improvement
Tips for Efficiency● Test simulations on many different machines
and operating systems
Preferred Tools● Word/ Excel● Jira/ Basecamp
Development
