Virtualization of Veterinary Hospital Building Plans

Peter CartaCharles Stocker

Project purpose and scope Building plan and Virtual Model Project Decomposition

◦ Modeling Building, Furnishings, and Objects◦ Camera Control and User Interaction◦ Other Animation

Difficulties and Fixes Conclusion & Relation to VR

Discussion Overview

Owner is in need of new facilities◦ Presented paper plans but has hard time

visualizing what the final result will be

3D Virtual simulation of building plans◦ Provide owner with more realistic view◦ Help provide feedback on layout

Assures plans fit needs

Project Purpose

Model 1 building plan◦ Fully furnished layout◦ User controlled motion and interaction

Present simulation over computer◦ Camera controlled with keyboard and mouse

Modeling and Animation◦ Virtools5.0◦ Maya

Project Scope

Building Plan

Virtual Model

VMO Walkthrough

Virtual Model

Modeling the Building◦ Virtools5.0

Individual wall segments Windows and Doors

Project Decomposition

Modeling Furnishings and Objects◦ 3dsMax

The cabinets were modeled◦ Virtool’s Resources

Chairs, laptops, and rugs◦ Online sources

Several models were used from TurboSquid.com Toilet, tables, bookshelves, tubs, sinks, and much more.

Project Decomposition

Camera Control & User Interaction◦ Movement Controls

Walk Forward and Backward, Turn Left and Right Keyboard W, A, S, D

Project Decomposition

Camera Control & User Interaction◦ Movement Controls

Camera Adjust angle with Mouse Pointer 360° Pan – Hold Right Mouse Button

Project Decomposition

Other Animation◦ Door Open/Closing

◦ Add to Immersion and Realism

Project Decomposition

Lighting and Shadows◦ Issue:

No contrast between walls Difficulties determining where you were

◦ Fix:

Difficulties and Fixes

Collision Detection◦ Issue:

Camera going through walls regardless of Collision Detection and Object Slider BB

◦ Fix: Individual Groups for each Room and Objects Multiple Object Slider BBs Lightened data strain and iterations on CPU by

dividing work load among multiple blocks

Difficulties and Fixes

Modeling veterinary patient beds◦ Issue:

Did not have access to free models of patient beds.◦ Fix:

Model a table and give it a metallic mesh!

Difficulties and Fixes

Scaling and Stretching◦ Issue:

Some models have several parts and even when placed

in the hierarchy manager together, they do not stretch appropriately.

◦ Fix: Get the model as close to an appropriate scaling See Refrigerator in Break Room

Difficulties and Fixes

Model Sizes◦ Issue:

Many models needed to fit snug to walls◦ Fix:

Scale models or remove certain models to make them appear to be snug.

Difficulties and Fixes

3D Virtual World◦ Building and Objects modeled in 3D to create the

world◦ Separates this application from flat paper plans

Immersion◦ User controlled tour

Every user can go and do what they please when in the simulation

Not restricted to one path◦ Realistic models and animation abilities

Relation to VR

Sensory Feedback and Interaction◦ Movement controls and angular adjustment

Giving the user freedom to explore at their leisure◦ Object Animations

◦ Future Additions: Sound – Barking and Meowing Animated animals/ Customers/ Receptionist Additional models to increase realism Fix collision detection with objects and walls
