OVERVIEW

• 3D MODELING– Hardware Needs

• Video Card (256+ MB)• RAM (2+ GB)• Processor (2.5+ GHz)

– Software Needs• ArcGIS Desktop with ArcScene• 3D analyst extension• Movie editor

– Data Needs• Contour (elevation) data

– DGN, DWG, SHP, ETC.– Preferably polylines

• Features Data– Preferably polygons

• Aerials– JPEG, TIFF, IMG, ETC.– Preferably JPEGs

Project Example

1) START WITH A 3D CAD FILE ( OR ANY OTHER DATA FILE THAT CONTAINS ELEVATION VALUES RECORDED FOR EACH LINE).

2) EXPORT THE CONTOUR POLYLINES TO A SHAPEFILE.

3) CLIP THE CONTOUR SHAPEFILE WITH THE CUT/FILL BOUNDARIES FOR THE PROPOSED ALIGNMENT.

4) COMBINE THE CLIPPED CONTOUR SHAPEFILE WITH THE PROPOSED ALIGNMENT CONTOURS.

5) CONVERT THE COLLECTION OF CONTOUR SHAPEFILES TO A TIN USING THE “3D ANALYST” EXTENSION.

6) ADD 3D FEATURES SUCH AS TREES, UTILITIES, VEHICLES, STRUCTURES, ETC. USING ArcScene® 3D SYMBOLOGY.

7) DRAPE AN AERIAL PHOTO USING THE TIN AS THE BASE HEIGHT.

8) ADD FEATURES FOR THE NEW ALIGNMENT USING THE TIN AS THE BASE HEIGHT.

VIDEO SIMULATIONS

• Use model and animation toolbar to capture video.

– Create animation file of keyframes• Series of camera positions

– Export to video• Captures a video based on the

preselected keyframe (camera) positions

• Must select a video file type

• Must select a codex to compress the video

– Can create an uncompressed video but the file size will be enormous

– Edit video• Combine video clips and add

captions using any video editing software available
