Study on the Stroke Features of 2D Automotive Sketches Archive - IT ...

Abstract

In the conceptual design stage of automotive styling,2D sketches, as an important tool, play a very important role for stylists to conceive the schemes.2D sketches have been widely used by stylists for their free.form styles, recording and communicating easily, much more information, etc. and they are the main patterns for the discussions of design proposals, and an important basis for creating 3D models. However,2D sketches, with the different expressions and styles, have attracted widespread attentions of stylists to effectively identify and extract the stroke features in order to improve the quality of design expression and speed up the transformation from 2D to 3D in the styling.Based on the understanding of 2D sketches and their roles in automotive styling, this paper has investigated the expressions, styles and featues of automotive sketches, and proposed a reasonable classification for the form lines of automotive features. Some typical automotive sketches have been analyzed according to the patterns of single stroke, line and surface, and light color. The features have been extracted by the experiment from the four forms:form lines, components, form shadings and non.form shadings. The analytic hierarchy process (AHP) has been applied to deal with the experimental data. It is proved that the classification of features is right.Automotive styling can be considered as a set of features. The automotive sketches have been classified into three patterns as mentioned above from many aspects of expression tools and materials. According to the components of automotive body and the definition of styling features, the information, from the front 3/4 view, the side view and the rear 3/4 view, has been described and listed in detail.The information of features has divided into the four forms, as mentioned above, according to the method and the process of of sketching based on the definitions. The features have been extracted by the experiment. The 3D information from 2D sketches has been divided, recorded and described by using PhotoShop tools.The data from the experiments have been analyzed and validated by using the method of AHP. The specific features in the sketches have been obtained in the patterns of single stroke, line and surface, and light color.The classification of features, the experiments of feature extraction and the method of AHP have initially solved the problem of identification and extraction of features that can effectively describe the 3D information from 2D sketches. The research is very useful for the development of 3D automotive sketching system. The method and the process can be considered as the references in 3D automotive sketching.

Giffords serves Thanksgiving meal at Ariz. base (AP)

TUCSON, Ariz. ? U.S. Rep. Gabrielle Giffords helped serve a Thanksgiving meal to service members and retirees at a military base in her hometown.

Giffords arrived in the dining hall at Davis-Monthan Air Force Base in Tucson at midday Thursday wearing a ball cap and an apron with her nickname of "Gabby" sewn on the front. She was accompanied by her retired astronaut husband, Mark Kelly, who also donned an apron.

Giffords used only her left hand as she served, a sign that physical damage remains from the injuries she suffered when she was shot in January.

Kelly supported her from her left side as she worked the turkey station on the serving line. He served ham.

The event marked the first time Giffords has met with her constituents since the shooting. After serving dinner, she mingled with service members, exchanging pleasantries and mostly one-word greetings and responses.

She did tell Airman 1st Class Millie Gray, of Kansas City, Mo., "Happy Thanksgiving, thank you for your service."

Gray said she had intended to only grab a plate and head back to her dorm to eat, until she heard that Giffords was going to be there.

"She's such an inspiration and her story is so inspirational, it really made me proud. I felt very proud and very humble," Gray said. "It just feels really good to see that she is out here supporting the troops, and just continuing to be an inspiration and a strong role model for Americans in general.

"She was very warm, asked how our meal was, which, of course, was amazing. The food is awesome," Gray said. "She and her husband were very, just delightful and asked a lot of questions. It was just very warm-hearted, and I told her she was an inspiration and she was very thankful for that."

Giffords and Kelly left after less than an hour.

Giffords has been undergoing intensive rehabilitation at TIRR Memorial Hermann in Houston as she recovers from a gunshot wound to the head. She was among 19 people shot Jan. 8 as she met with constituents outside a Tucson supermarket. Six people died.

The congresswoman arrived in Tucson on Tuesday evening from Houston for a private visit with her parents and other family members and friends.

"It's always special to have a member of Congress come and spend time with the troops and show support," said Brig. Gen Jon Norman, acting commander of the the 12th Air Forces, Southern. "But after everything that she's been through, it's a little bit more special."

Giffords' staff said base officials originally asked a member of the congresswoman's staff to take part in the annual Thanksgiving dinner. When the staff member told Giffords about the event, the congresswoman decided she wanted to go herself.

Giffords previously returned to Tucson for the Father's Day and Labor Day weekends.
