BOULDER, Colo.--(BUSINESS WIRE)--Oct. 16, 2001

Spatial Corp., a market-leading provider of world-class 3D software components, today announced the release of version 7.0 of its Standalone Deformable Modeling software.

The new release improves on the quality and functionality of previous versions, including continuity control, surface smoothing and ease of use.

"Standalone Deformable Modeling is at the forefront of free-form surfacing technology, and with version 7.0 provides more value to our partners," said Phil Spreier, product manager, Spatial. "The Standalone Deformable Modeling component has proven to be an effective tool for all stages of the product design cycle, from conceptual design to production-quality surface finishing. Our partners can implement version 7.0 in their applications to interactively create Class A surfaces, control continuity between surfaces and specify spring loads for smoothing interior regions of surfaces. This powerful and intuitive tool set can be used to enhance a wide range of 3D applications from automotive outer body design to free-form architectural design and more."

"Our partners using the Standalone Deformable Modeling component do so because they require the very cutting edge of surfacing capabilities," said Linda Lokay, vice president of sales and marketing, Spatial. "Our partners demand performance, quality, and reliability. In this release, we sought to exceed expectations, adding advanced functionality that will give our partners an edge in the marketplace, as well as accelerate their time to market."

The Standalone Deformable Modeling component is an interactive sculpting tool for creating and manipulating free-form curves and surfaces. Its local and global editing features allow easy manipulation of B-spline and NURBS curves and surfaces to achieve a very high level of artistic design while retaining the ability to generate a precise, machinable surface.

New Modeling Features and Functionality in Standalone Deformable

Modeling 7.0:

-- Area Loads -- Allows spring loads to be applied to interior or exterior
regions of any piece-wise linear or convex polygon, so that they can be pulled
onto a target surface. This tool is particularly useful for specifying masking
regions in Class A surfacing applications.

-- Improved Continuity Control -- Allows independent control of curvature,
tangency and position continuity both interior to surfaces and along
surface-to-surface transitions.

-- Object-oriented Graphics Interface -- Standalone Deformable Modeling now
supports an easy-to-use, object-oriented interface for manipulating and
rendering curves and surfaces. This new interface makes it easy for partners to
integrate the Standalone Deformable Modeling component in their applications
with minimal start-up cost.

-- Improved query functions -- New functions for querying relationships between
Deformable Modeling pressures and springs and their associated geometry.
