					Chrysler Educational Toolkit         - Introduction
In an unprecedented move a major automotive company is releasing to the public 3D data of some of their vehicle fleet for the intended purpose to
help train those interested in a career in Automotive Visualization. This guide is the help for students and instructors to sort through the wealth of
information being provided and help address issues that might be faced. The data and information available for download is the same materials that is
provided to companies to create CGI images and animations for Chrysler.

The Southeast Michigan ACM SIGGRAPH professional chapter is happy to support Chrysler's efforts to promote and train CGI artists. The
organization will help to advise, promote, and create materials related to their CG education outreach efforts.



In this guide we cover the following topics:

Why is Chrysler Making the Data Available for Free?

Chrysler believes that it’s offering of this 3D Educational Toolkit to the public at no charge to be the first of its kind in the industry. This gesture is
intended to provide an impetus for 3D Visualization classes everywhere and as a means for their instructors and students to hone their skills without
the requirement of an additional vehicle data fee. In this way, Chrysler hopes to see its data provide the material for quick growth of 3D Visualization
Education to match this rapidly expanding industry.

As a leader in automotive visualization Chrysler realizes the importance of developing the creative talent that can work with their data. It is in their
interest to have a steady supply of artists that can do the increasing amounts of CG imagery and animation for their expanding marketing needs.

About Chrysler Vehicles:

Realize that vehicle classes such as Wrangler, Viper and Sebring each have several trim levels to them. For instance you can get a Jeep Wrangler as
either a Base model, Sport, Sahara, or Rubicon. These are considered the different trim levels of a Jeep Wrangler. A vehicle can be configured in a lot
of different ways: you can choose the exterior paint color, the interior color, type of seats, whether it is equipped with Navigation system, or Mopar
accessories. To see examples of Vehicle Configurator, you can visit

Color Charts

The color charts indicate what combinations of trims have what kind of color availability. In the Trim summary chart example below you will notice that
all the Jeep Wrangler trims come in either color code DD or JJ. DD refers to a two tone interior color scheme of Dark Slate Gray and Med Slate Gray.
While JJ refers to a Two tone color scheme of Dark Khaki and Medium Khaki.

Color Compatibility Chart: This chart refers to what exterior paint colors are available on each trim level.

Interior Color breakup charts: These are charts that specify the color that parts of interior geometry should be for a particular interior color code for a
particular trim. Normally the parts in the 3d geometry are assigned materials shaders for one available interior trim color.

Component Graphics

Included are images that can be used to texture the radio navigation screen, to texture the instrument panel cluster if the cluster wasn't included as
geometry, and related logos and badging that may not have been included as geometry.


Grain Chart

These indicate what type of bump texture gets applied to the various interior parts. Some bump textures have names such as Millennium or Machine
Weave, CPM501, CPM526, CPM493. Below are examples of grain chart for

Material Samples

Material Samples are used to create texture maps for vehicle interior, and include the following categories of materials:
        • Convertible Top Fabrics: scans of fabrics used for convertible top
        • Exterior Colors: scans of exterior paint samples and digital multi-angle readings of LAB, CMYK and RGB values of exterior paint
        • Grains: scans or photographs of interior plastic grain textures
        • Interior Colors: digital representations of interior colors based on RGB values
        • Interior Fabrics: scans of cloth, leather, vinyl, carpet and flooring materials
        • Interior Finishes: decorative finishes used on interior Instrument Panel, Door trim, etc.

Quarter Scales

These PDF documents indicate how the seats should be constructed. They provide information about seat code, material application, and general seat
shape. Quarter scales serve as a good addition to reference photography of seats.


Wheel Chart

Wheel charts are useful to identify which wheels are available on a particular trim and which tire gets put onto the wheel.

Reference Photography

Extremely useful are the photographic images of the Exterior, Interior and mechanicals that can be used to develop photorealistic material shaders,
identify geometry not provided within the geometry data such as cargo nets. One note of caution is that the reference photography is not always 100%
product correct or shot with interior parts that have had grain applied to the parts.


Tire Photography

Photography of the tires can be used to created texture maps to provide detail to the tire's sidewall.

System Requirements:

To assemble a full vehicle requires a large amount of memory. A computer with a 64bit operating system and 4GB is recommended. Computers with
less RAM can still work with the data: it might be that only selected parts are loaded and rendered then assembled in an image layers or as
composited animation layers.


Software:

Autodesk Maya 8 or current version of the software is required to be able to open and translate the geometry files. Other software packages may be
used for final rendering or animation. Please see the list of recommended software packages on our web site, as well as links to student versions of
those software packages, available to be downloaded on your machine.


Technical Tips:

There are variety of 3D Computer Graphics programs capable of creating automotive CG imagery. To use the Chrysler .mb files in other 3D programs
requires the files be translated to a format that the software can read. To translate the files to other formats you will need a Autodesk Maya 8 or current
version. Maya is capable of translating the .mb files into a variety of formats such as .FBX and .obj.

Many companies working with the data use additional software to successfully translate the files to other formats. These would include Deep
Exploration from Right Hemisphere, and Polytrans from Okino.
