3-D Editor, Part I: Functionality, Friction Zones & Importing Models
Instructor: Daniel Peralta
Time: Thursday, 8:30 AM

Description:
The purpose of this workshop is to expose the student to the features and capabilities of the 3-D Editor. The 3-D Editor can be used for creating simple environment models or for enhancing imported DXF or VRML format models. Most importantly, the 3-D Editor is the only tool for assigning friction factors to areas of the environment model.

The workshop will cover the basic functionality of the 3-D Editor, develop simple environment models to reinforce the concepts, and then focus on importing and enhancing DXF format models for use in simulations and reconstructions.

The following material is covered:

  • Basic Overview - The student will learn the basic capabilities of the 3-D Editor, including creating surfaces, blocks, spheres, cylinders and text.
  • Editing Overview - The student will learn how to edit the geometry and material attributes of previously created environments.
  • Using Friction Factors - The student will learn about GetSurfaceInfo(), the basic object types (Road, Friction Zone and Other), how to edit the object’s friction factor,
  • Object Precedence - The student learns about object hierarchy and how HVE deals with tunnels, bridges, and other issues related to object precedence using examples such as an oil slick, speed bump, sidewalks and others.
  • Saving Files - The student learns various methods of saving imported files, including saving the environment for use in other cases or saving objects into the library for use in later environments.
  • File Types - The student learns more about the supported types of file formats supported by HVE.
  • Pre-processing Environment Models - The student learns how to prepare an environment model in AutoCAD for importing into the Environment Editor
  • Using Aerial Photos - The student learns how to build a scaled surface and properly apply an aerial photo or bitmap image to the surface.
  • Creating a Complete Environment – The student will build a complete environment using the individual items created in this workshop.

Multiple examples will be explored by the students using handouts or materials provided in the workshop. Attendees are encouraged to bring their laptops along with their AutoCAD (or similar) CAD software in order to produce sample DXF files for import into their HVE or HVE-2D software. The CAD application used for examples provided by the instructor will be AutoCAD.

Upon completing this workshop, the student will be able to use the 3-D Editor to create and edit virtually any type of drivable surface, as well as import files created in AutoCAD, 3DStudio (or other programs) into the Environment Editor and save them in the case file or as a separate file available for use in other cases.

Advanced 3-D Environments, Part I & II
Instructor: James P. Sneddon
Times:
  • Part I - Thursday, 8:30 AM
  • Part II - Thursday, 1:30 PM

Description:
The purpose of this workshop is to extend an HVE User's abilities to build detailed terrain models for their simulation studies. Using a combination of CAD tools and the 3-D Editor, a terrain model will be built of a real-world roadway example. This workshop uses the Rhinoceros NURBS modeling program extensively. The following material is covered::

  • Review of actual site and identification of key elements.
  • Planning terrain model requirements.
  • Discussion of surveying and data collection methods
  • Producing a preliminary terrain model
  • Add additional roadway markings such as center lines and fog lines
  • Establishing mesh density and surface normal orientation
  • Importing 3-D Environment from 3rd party CAD or COGO software
  • Quality checking the finished terrain model using simulations of vehicles driving on the surface

Upon completing this workshop, the student will understand the methodology used to build a preliminary model and be able to either build models themselves, or provide direction to a survey company to provide a model for use in HVE. Additionally, the student will be familiar with the processes required to build detailed models of any roadway or terrain required for their own detailed simulation studies.
