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
