important• Factors in accuracy• What it’s used for and software• Steps to how it is done• Problems, issues & solutions

Architecture example

Software Examples

How it’s made

• Geometric Modeling

Lets look at how we make an object.

The Basics: Creating realistic objects

Add details and views

Creating our scene

Image Size and perspective

Transportation example

Conclusion• Scene visualization is important to give people a visual representation of your

data .• The accuracy of your rendering is primarily dependent on how much detail you

want to put into it.• This type of visualization is used for data representation in many industries

from scientific to government data. There are a number of software options available for the creation of a scene but most commonly we saw 3DS max.

• Rendering of a whole scene basically follow the following steps: – add ground/sky texture, – insertion of created objects, – lighting and shadowing for scene, – ensuring perspective is ideal, – adding atmospheric affects.

• Problems and solutions are varied and many but many of them generally are solved by how much detail you want in your rendering.

Question 1

• What is the number one determining factor governing how true to life your scene will be.a) The GIS datab) The software you use to create itc) The amount of accuracy you need/wantd) The amount of time and money you have

Question 2

• A GIS Scene is easily created in minimal time.a) Trueb) False
