Generating A Virtual Campus From Arcview Shapefiles
Using polygon data for building shapes and height data for individual buildings,
we were able to render a 3D model of campus in Arcview and export it to
VRML 2.0 using the 3D Analyst extension.
<-- At left is an example of the data we had available for each building on campus. At right is an image of the polygons before -->
they were extruded.Process:
I added the Basemap.shp shapefile to a new View in Arcview. In order to generate VRML, I turned on Arcview's 3D Analyst (Click File -> Extensions -> 3D Analyst). That added another category to the Project Window: 3D Scene. I created a new 3D scene, since none existed, and added the themes from our View. To extrude the buildings into 3D, I selected 3D Properties from the Theme menu. Under Extrude featured by value or expression, I used [B_ht], the value for each polygon that contains the height data.This is a wireframe diagram of Gould Simpson as it was generated by Arcview:
