3-D dome display explores biology
First reported in Vision Systems Design (May 2001, p. 17) as a 360° dome viewer, a spherical three-dimensional (3-D) display from Actuality Systems Inc. (Reading, MA; www.actuality-systems.com) is being evaluated by its first beta user. Structural GenomiX Inc. (SGX; San Diego, CA) is using the Helios 20-in.-diameter dome viewer to help develop experimental and computational structural biology that can transform genomic information into structural templates for drug discoveries.

A multiplanar, volumetric, 3-D color dome display can present medical imagery, such as a molecular visualization (top), or a military representation, such as a combat aircraft flying over a mountain-hidden target (bottom). Other expected applications include mechanical computer-aided design, graphics animation, and e-commerce.

In sum, the dome viewer can show high-resolution color images that appear to hover in space and permit several users to move completely around the 360° display and view images from any angle. This technology is claimed to provide the highest-resolution volumetric imagery available. Gregg Favalora, Actuality Systems founder and chief technology officer, says, "This type of volumetric 3-D display will impact a number of different fields. But the range of possible uses for drug design and biotechnology is so varied that it is well suited for beta-testing real-life sciences."

Drug design has traditionally involved a trial-and-error process. Recently, however, many pharmaceutical companies have undertaken a more rational approach to drug discovery. For example, chemists now carefully consider the 3-D shape of the chemicals that their drugs attack. The 3-D shape of a drug target molecule is, in many cases, a complex structure that to a layman looks like a tangled-up spider's web (see photos). This imagery is harder to comprehend on today's flat computer screens.

Therefore, companies such as SGX are looking to advanced display technologies such as Actuality Systems' volumetric 3-D display, which is under investigation by SGX to determine if it can help scientists understand and collaborate on protein structures. Now, in real time, scientists can rotate and zoom in on molecules using software they're already familiar with and with a 3-D copy of molecules as they tumble in real-time in the display.

The large number of newly mapped genes in the human genome has markedly increased the pool of potential drug targets. The challenge that confront scientists working to develop new drugs is that they need detailed information on how the protein under investigation interacts with compounds under study. After a protein structure is determined, scientists can use a method called "structure-based drug design" to develop compound libraries aimed at a specific protein target.

Doug Livingston, SGX vice president of chemistry and new technologies says, "This 3-D display offers a new paradigm for us. Many of our scientists spend a lot of time working on a flat screen with goggles that only simulate 3-D. Using the Actuality Systems' display allows a more natural process. It facilitates collaborations among our work teams, and, when used as a presentation tool, it could help our partners and clients better understand the data."

Unlike some 3-D displays that require special stereoscopic goggles to simulate multidimensional imagery or flat-screen monitors that translate 3-D data into flat 2-D images, the Actuality Systems technology is volumetric, which means that it illuminates volume pixels (voxels) throughout the full range of 3-D locations within the spherical display. Moreover, a custom embedded-graphics architecture takes computational load off the user's workstation, enabling an animated 3-D imagery that can be controlled and maneuvered from a keyboard.

Actuality Systems uses proprietary graphics-rendering algorithms to generate the very fast, high-performance scene drawings that are crucial for smooth movements. In addition, it uses a high-speed, high-resolution projector to create bitmapped 3-D imagery that enables users to access 100% of the available volume instead of just a small portion of the display as accomplished with traditional vector-based systems.

The 3-D display offers a resolution of approximately 100 million voxels. In contrast to flat and square pixels, voxels also provide depth. Resolution is described in terms of a stack of flat slices arranged around a centerline similar to thin wedges of an apple around its core.

Doctors can also benefit from viewing medical images in a volumetric 3-D format. Traditionally, a radiologist looks at hundreds of 2-D "image slices" through a patient's body from a computed-tomography (CT) or magnetic-resonance-imaging (MRI) system. Then, the radiologist describes the location of a tumor, for example, to a surgeon, who then performs an operation. It would make sense to empower nonradiologist physicians—such as surgeons—with a complete and highly detailed representation of the tumor's location using a 3-D display. The display could also be used to give patients a better understanding of surgical procedures or in plastic-surgery simulation to show "before" and "after" presentations in a floating, lifelike 3-D display.

The company expects to disclose other beta users in the next few months and is planning to ship commercial units by the end of 2002.
