### Load 3D Analyst Extension

Load 3D Analyst Extension
• Tools, Extensions…

### 3D Scene

3D Scene
• Load from extension toolbar or start menu
• Uses .sxd file format
3D Scene
• 3D Scene with layer added
Triangulated Irregular Network
• Triangulated Irregular Network (TIN) Structure
• Defined by two elements: a set of input points with x,y, and z values, and a series of edges connecting these points to form triangles.
• Each input point becomes the node of a triangle in the TINstructure, and the output is a continuous faceted surface of triangles.
Create TIN
• Create TIN from topo features
TIN Properties
• Color changed and soft lines turned off

### Drape Features to TIN

Drape Features to TIN
• Edit layer properties

### Extruding 3D Features

Extruding 3D Features
• 3D buildings includes 3D heights
Extruding 3D Features
• Extrude using Height field
Resultant Layer Extruded
• Buildings draped to TIN and extruded

### Navigating a 3D Scene

Navigate a Scene
• Navigate button
Flythrough a Scene
• Choose Fly button and slowly move mouse
• Left mouse: increases speed
• Right mouse: decreases speed
• ESC: stops flight
Multiple Views
• Add New Views

### 3D Effects

3D Effects Toolbar
• 3D Effects Toolbar
Transparent Effect
• Set layer transparency
Layer Face Culling
• Turns off the display of front or back faces of an areal feature or graphic
Layer Lighting
• Switches lighting on/off
• Defines smooth or flat shading
Depth Priority
• Changes layer’s drawing priority

### Animations

Record and Play Animation
• Animation Toolbar and Tools
• Record Animation
• Animation Controls
• Record button
• Fly button
• Stop button
• Play Animation
• Play button
Save Animation
• Save as ArcView animation (.ASA)
Save Animation
• Export as .AVI or .MOV video
• Opens ArcView animation
• Ready to play
3D Symbols
• Start with 2D point symbols (street trees)
3D Symbols
• Add layer and display (drape) in ArcScene
3D Symbols
• Swap with 3D Symbol
3D Symbols
• Resultant layer with 3D symbols

### Line of Sight Analysis

Line of Sight Analysis
• Add TIN in ArcMap
Line of Sight Analysis
• Create Line of Sight
• Set offset
• Pick points
Resultant Line Analysis
• Lines showing visibility (green) and obstruction (red)

### ArcGlobe

Launch ArcGlobe
• Choose from 3D Analyst toolbar or
