At ProtoTech, we empower businesses with cutting-edge 3D engineering solutions by using Open Cascade technology, a powerful object-oriented CAD/CAM/CAE platform. Our development team uses the Open Cascade Technology (OCCT) framework to build advanced 3D modeling, visualization, and interoperability solutions tailored for manufacturing (CAM), numerical simulation (CAE), measurement equipment (CMM), AEC, and industrial design sectors. We create OCCT-powered solutions for Windows, macOS, Linux, Web (WebAssembly), iOS, and Android.

Edit Template

Open Cascade Technology (OCCT) is a powerful object-oriented C++ class library designed primarily for developing 3D CAD, CAM, and CAE applications. It provides advanced geometric modeling, mesh processing, visualization, and data exchange capabilities, making it a leading platform for building custom engineering, simulation, and design software. Set of advanced features for 3D CAD/CAM/CAE application development, including:

3D Geometric Modeling

Robust algorithms for creating and manipulating 3D geometry using B-Rep (Boundary Representation). Includes Boolean operations, fillets, shape healing, and complex intersection calculations.

Visualization

A powerful visualization module with support for OpenGL/OpenGL ES rendering, interactive 3D viewers, shading models including real-time PBR (physically based rendering), metal-roughness, texture mapping, and interactive selection.

Data Exchange

Built-in support for importing and exporting industry-standard CAD file formats such as STEP, IGES, STL, OBJ, and glTF 2.0. Includes advanced shape healing tools to improve CAD data quality and interoperability.

Mesh Processing

Tools for working with tessellated (triangulated) models, including 2D polygon triangulation and mesh optimization, mainly for visualization preparation.

Application Framework (OCAF)

A high-level framework to simplify CAD application development, providing document management, attribute inheritance, persistence, and application-specific data handling.

Multi-threading and Performance

Support for parallel task progress indication, background BVH tree computation for efficient selection, and WebAssembly compilation for web-based applications.

Extensibility

Flexible modular architecture allows integration with other SDKs and frameworks and customization for specialized application needs.

For more than 15 years, we have been using the Open CASCADE Technology (OCCT) for 3D application development. From modeling and visualization to CAD data translation and interoperability, our services cover the entire lifecycle of application development.

Our Open Cascade capabilities include:

Developing custom 3D modeling and visualization tools using OCCT APIs.
Integrating Open Cascade with other CAD kernels and visualization SDKs.
Building CAD data translation modules supporting STEP, IGES, Parasolid, and STL.
Optimizing geometric algorithms for high-performance computing.
Web-enabling 3D models using Open Cascade with frameworks like HOOPS or WebGL.

By combining Open Cascade with modern visualization and AI frameworks, ProtoTech delivers next-generation 3D tools that accelerate engineering innovation. We integrate OCCT with C++, .NET, JavaScript/WebAssembly, Unity, Unreal Engine, and cloud platforms for scalable solutions. Through deep domain expertise and years of experience, ProtoTech transforms complex engineering challenges into scalable digital products.
