5 Tips from the CyArk Team

It is often difficult to capture the beauty of a site with drawings and photographs alone. This is why animations are often helpful for viewers to get a sense of the space and relation of objects to one another. Yet, animations can be a tricky thing to master—particularly in Leica’s Cyclone software. This list is intended to help you add greater eloquence and expression to your Cyclone animations while speeding up the preparation time.

1) Simulate the Animation
Use the view mode to fly through the modelspace to get an idea of what areas would be the best to animate. Manipulate the modelspace as though you were watching an animation. This will help you notice if there are areas that you may not want to show, or areas that need emphasizing.

2) Pick a Point
When you figure out what will be the focus of your animation, pick a point that will be the center with Cyclone’s Seek Mode tool.

Save a “view” (located in the drop-down menu “View”, under “Save View”) with this point as the center.

By doing this, you will always be able to reference this point, even when you pan through the modelspace. With simple, rotating animations, it is best to always check the box “Keep Current Focal Point” in the Animation Editor window.

This will ensure that your animation will have a smooth gliding effect and will also keep the focus of the animation on the point that you selected. Note that this, however, may not be the desired result if your video is traversing a site as it may then cause unintentional camera-angle changes.

3) Frames
Make the number of frames between key points a multiple of 15. Exporting the animation as a 15fps movie will make the movie smooth and consistent. Keep in mind that the spacing of Key Points will affect the amount of frames needed between them; e.g., if you want two seconds between the key points indicated, then 30 frames will be needed.

4) Number of Cameras
The number of cameras used in your animations will depend on the size of the modelspace. But a good number should be 4-15 cameras. If you have more, or less, than it is possible that the animations are too complicated, or not enough. In either case, the animation may become bumpy or uncontrolled. Here we see a Moai from Rapa Nui (Easter Island) with 4 cameras located around the monument to create a simple fly-around animation.

5) Animation Sequence Length
If you desire long and/or complex animations, then it is best to create several short animations with these tips and then merge the individual, short clips together in a separate video editing program. This provides greater video editing ability in a second program more suited to video production; these aditional editing abilities would include options such as fades, transitions and title sequences. The short videos are also easier and less time-consuming to generate within Cyclone.

As social media becomes a hit with agencies, GSA plans more offerings

Agencies have launched social networking applications at such a fast pace that government officials said on Friday that they plan to add more applications, such as Apple’s popular media store iTunes and the career-networking site LinkedIn.

The government also is negotiating agreements with social publishing site Scribd and commenting platform Intense Debate, said Martha Dorris, acting associate administrator for the General Services Administration’s Office of Citizen Services and Communications. The federal government has signed modified terms of service agreements to allow agencies to use social media sites Flickr, Facebook, YouTube, Vimeo, Slideshare and AddThis, among others.

The response to the agreements has been excellent, Dorris said. Agencies have set up Facebook profiles, Twitter accounts and YouTube channels to share information with the public. “We’re looking at taking information wherever citizens go to get information,” she said, adding GSA will consider adding more social networking sites, depending on requests from agencies.

Sheila Campbell, team leader of best practices for USA.gov and co-chairwoman of the Federal Web Managers Council, said tools such as Twitter offer the government the ability to communicate with the public very quickly in times of emergency. She cited as examples the Center for Disease Control and Prevention’s use of social media during its peanut recall and the swine flu outbreak.

Despite the common perception that social media tools are used mostly by younger users, baby boomers are the fastest-growing segment of users for most applications, according to Dorris. She said agencies were inspired by President Obama’s use of new media tools during his campaign and by WhiteHouse.gov, and have applied those lessons to outreach programs.

“Government needs to provide services and information the way the public wants it,” Dorris said. “One way is to engage the citizen, get an understanding of what they want. Give them a chance to be part of the decision-making in a way they never have before.”

When asked how agencies can move beyond simple broadcast of information to using social media to collect feedback, Dorris said Obama’s recent request for public input to support his open government initiative is an example. She said requests for public comments on health care and the recovery act were other examples.

“Let the public rate comments,” Dorris said. “Then take the issues, rated and ranked and look at the top 10. I think there’s a value to that externally and internally to solicit comments and feedback within your organization.”

The Federal Web Managers Council is working with agencies to craft policies for using social media tools, but the rules aren’t likely to be much different from existing guidelines on releasing information publicly, according to Campbell. “I think the same rules and ethics apply,” she said. “If you’re on Twitter, you shouldn’t be posting confidential information, just as you wouldn’t if speaking at a conference.”

GSA general counsel Seth Greenfield said any new social media policies would only complement existing ethical standards and regular use policies being applied to the use of IT.
