Rendering Styles


Rendering Styles


By Elizabeth Mott


From architectural plans to animation for films, games and TV commercials, 3-D drawings can bring the worlds of commerce and art together. The powerful flexibility of rendering styles broadens the ways in which an artist or architect can use a single drawing file to present an illustration for approval or show a client an interim step toward construction. Rendering styles address basic appearance attributes from drawing style to lighting, and even change the apparent location of a scene.


Wireframe Renderings

·         To show the structure of an object or visualize the details of a molecule in a scientific study, rendering styles can hide or display the underlying details of a CAD or 3-D drawing to provide "cutaway" views. Versions of this style also produce blueprint drawings that detail the construction of an object to assist in setting up manufacturing processes and analyzing structural strengths or weaknesses. Rendering styles can display part of a drawing in wireframe and the rest in a realistic style, highlighting part of an automobile or building, for example.

"Hand-Drawn" Styles

·         Some rendering styles "loosen" lines and edges, transforming the rigid precision of a computerized drawing into a final image that looks more like hand-drawn art. Stylings can range among pen and ink, pencil and other drawing media, altering the texture, thickness and colors of strokes as well as the appearance of the material on which they draw. Some of these styles find their greatest usefulness in producing artwork rather than rendering architecture. Others can adapt to either application, creating concept drawings of structures that look like throwbacks to the days when architectural firms created hand drawings.

Lighting Design

·         Programs that produce 3-D art can vary the ways in which light interacts with the textures, objects and creatures in a scene. Rendering styles make it possible for an artist to draw a scene and alter the apparent time of day or sunlight in an outdoor visualization, or add and change light in an interior to produce day or night versions. Different rendering engines use different types of calculations to produce scenic lighting, enabling an artist to change the appearance of materials and surfaces from slickly plastic to physically detailed without altering the underlying drawing file itself.

Scenic Backgrounds

·         Artwork, architecture and 3-D product visualization can benefit from placing scenes and objects in the context of a background setting. Rendering styles can insert images behind the principal subject matter. With these options, an architect can show how a building looks in the context of existing construction and landscaping in more than one location without redrawing an entire project. An artist can place a detailed character prototype in various scenes of an animated sequences. Because these backgrounds only become part of the artwork when it renders, they don't increase 3-D file size.

How to Get a free US Phone Number


This tutorial describes how you may easily get your own USA local phone number from anywhere in the world without spending a penny.
Once you have a US local phone number, your friends and relatives in the US will be able to dial you from their landline or regular cell phones without paying international rates. The calls can be forwarded to your mobile phone or desktop based VoIP phones.



Getting your own USA Phone Number - Step by Step


Step 1: Sign-up for a free account with CallCentric.com and click continue. CallCentric will send you a confirmation mail to verify your email address.

Step 2: Once you’ve verified the email address, provide your city and country code, agree to the terms and conditions and click “Sign me up.”

Step 3: CallCentric will now provide you with a virtual tour of their websites. Skip it and choose – “Go to My CallCentric.” The next screen will list your CallCentric # in the format 1777** – copy that number to the clipboard.

Step 4: Open a new browser tab and go to phone.ipkall.com. Set the account type as SIP and paste the CallCentric # from the clipboard into the field that says SIP Username. The hostname is in.callcentric.com and choose the same email address and password that you used while setting up your CallCentric account.

Note***: The default area code for your local US phone number is 253 but you may choose a different one from the drop-down. For this example, I’ll go with 425.

Step 5: Within a minute, you should get an email from ipkall.com with your new local phone number. Keep the email handy as you’ll need it while configuring the SIP client.

Step 6: Now that we have got ourselves a US phone number, let’s activate it.

6a: Download and install Express Talk on your computer. The trial version is good enough for our task. Make sure that you don’t install any of the “optional components” like toolbars, etc. during the setup.

6b: During installation, choose the default options for all the wizard screens. When you are on “SIP Setup,” choose “Yes, I already have a SIP account” and click Next. Fill the SIP details as in Step 4 above. Finish the setup.

6c:
Once the setup is complete, go back to your My CallCentric page and refresh it. You should see a notification saying – “your phone is registered.” Done!

Update: You can grab a SIP VoIP client for your mobile phone and configure it with your new CallCentric /ipKall number. Most Nokia Symbian phones can be configured for SIP without external apps or just search for “SIP phone” in iTunes or the Android marketplace. Popular mobile app Fring is free and also supports SIP.
