Product Overview

HOOPS Visualize

2D & 3D Graphics Engine for Desktop, Mobile and AR/VR Applications

HOOPS Visualize is a 3D graphics SDK that enables rapid development of high-performance, cross-platform engineering applications. Key features include:

  • High-performance, engineering-centric visualization which uses highly optimized OpenGL or DirectX drivers to take full advantage of available graphics hardware

  • Thread-safe C++ and C# interfaces, which internally utilize multi-threading

  • GUI-independent event handling to facilitate code portability across common GUI frameworks such as MFC, WPF, QT, and Cocoa

The cornerstone of HOOPS Visualize is the graphics kernel, a full-featured, engineering-focused scene-graph technology that we call Core Graphics. Core Graphics is integrated into a framework that provides many of the standard capabilities found in engineering applications.

High Quality Rendering SDK

High Performance

HOOPS Visualize offers optimal graphics performance on all supported desktop, mobile, AR and VR platforms and devices. By utilizing automatic scene optimization techniques and advanced culling it ensures a highly interactive framerate for even the most complex models.

High Quality

HOOPS Visualize takes advantage of modern graphics hardware, with advanced shadowing techniques, ambient occlusion, reflections, fast and accurate multi-layer transparency, fast hidden line and other rendering features. It also supports Physically Based Rendering (PBR) materials for even more realism.

Ease of Use

Built from the ground-up with scalability and minimal “time to first interaction” in mind, HOOPS Visualize handles the largest assemblies with tens of thousands of components or more and provides best-in-class rendering performance with any CAD data.

HOOPS Visualize is more than just a graphics engine, it is a framework for building engineering applications with an engineering focused scene-graph technology at its core. Wrapped around this graphics core is a customizable and extendable class layer that encapsulates a lot of high-level functionality found within engineering applications and offers integrations with other components like solid modelers.

HOOPS Visualize utilizes “Sprockets”, hooks into the event loop of the application and provides many of the standard operators used in engineering software applications. The operators in Sprockets range from simple camera operators to advanced measurement and redline operators. The APIs to these operators are designed to give developers full flexibility to customize them to meet their needs.

The Sprockets layer also includes integrations of a variety of complementary components that are widely used within engineering software applications. Through these integrations, developers can easily load and interact with a wide variety of CAD data. The HOOPS Exchange integration allows developers to easily import a wide variety of CAD formats. Once the data is imported, developers can take advantage of high-level APIs to do common tasks like isolate/hide/show parts in an assembly and iterate through views in the model. Integrations with Autodesk's RealDWG toolkit and Trimble's SketchUp SDK are also provided.

The Sprockets layer also provides an integration of the Parasolid modeling kernel. This integration allows developers to quickly leverage the power of Parasolid in a working application.

Finally, HOOPS Visualize comes with several sample sandbox applications that demonstrate HOOPS Visualize working with the different GUI toolkits. Sandbox applications are provided for each of our supported GUI toolkit integrations and provide a good starting point for developing your application.

Built-In Features

Built-In Measurement & Markup

HOOPS Visualize has many pre-built operators to measure lengths, distances, and angles within a CAD model, utilizing the original boundary representation (BREP) data if available to provide precise results. Another set of operators provides rich support for model markup in 2D and 3D.

Rich Line & Text Support

HOOPS Visualize offers best-in-class support for line rendering with a rich selection of custom line styles, full control of line thickness, multi-line support, infinite lines and many other features required for professional engineering applications. It also supports fast and high-quality rendering of 2D and 3D text with full internationalization support, extensive support for system and TrueType fonts, granular per character attributes and styles, predefined Geometric Dimensioning and Tolerancing (GD&T) fonts and much more.

2D Support

HOOPS Visualize handles 3D models and 2D drawings equally well, utilizing its advanced line and text rendering as well as its support for clip regions and other features to accurately display even the most complex drawings.

Built-In Printing Support

HOOPS Visualize includes dedicated support for printers and plotters offering fast, high quality and high-resolution printing for PDF, Postscript and Graphics Device Interface (GDI) devices utilizing a sophisticated hybrid vector/raster hardcopy approach.

Advanced Selection & Highlighting

HOOPS Visualize has highly customizable support for selection and highlighting with many advanced techniques to quickly highlight entities within its scene graph and precise analytic and image-based picking of entities or sub-entities such as lines, faces and points.

Massive Point Cloud Support

HOOPS Visualize provides a range of interactive navigation and analysis tools specifically aimed at working with point clouds and laser scan data with features like eye-dome lighting and splat rendering offering best-in-class visualization of point cloud data. Utilizing dynamic level of detail combined with an optimal out-of-core approach HOOPS Visualize can render point clouds with billions of points interactively.
