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
