This article provides a high-level overview of a frame rendering graph implemented by TKOpenGl (OpenGl_GraphicDriver). Although it is named here as a “graph”, it’s not that flexible and the overall structure looks pretty flat, as could be seen later on diagrams.

Article might be useful to OCCT developers and to advanced OCCT users wanting to learn more about low-level OpenGL rendering aspects of OCCT 3D Viewer, to see a better correlation between high-level (AIS) and low-level (OpenGl) layers, to figure out how and where to implement tricky effects or to understand how to optimize application rendering performance.

Open CASCADE Technology works on a vast range of platforms, and it is one of high priorities to keep supporting major compilers.

I have prepared a short anonymous questionnaire to collect some statistics, and you are welcome to share your opinion on this forum thread.

Open Cascade is pleased to announce a new public release of Open CASCADE Technology (version 7.6.0).

Open CASCADE Technology version 7.6.0 is a minor release, which includes more than 410 improvements and corrections over the previous minor release 7.5.0.

Version 7.6.0 introduces new features of most OCCT modules and components.

Forthcoming OCCT 7.6.0 release improves reading and writing of OCAF documents for binary formats of files. Now it is possible to load only a part of the document or append some part into an existing one.

Hello,

We are pleased to inform you that the new release of OCCT, 7.6.0, is ready for beta testing, and invite you to test this beta version in your applications.

Besides being widely applied in open-source and commercial projects, Open CASCADE Technology (OCCT) is actively used at an academic and research levels around the globe. To provide insight into it Open Cascade launches a new section devoted to OCCT-based research on a renovated Development Portal. It gathers hundreds of research and scientific articles from prominent universities and organizations in more than 40 countries.

Being the only open-source full-scale 3D geometry library Open CASCADE Technology (OCCT) is commonly used in academic and research spheres by high-profile organizations all around the world including prominent universities, scientific institutions, and even R&D departments of commercial companies.

Open Cascade continues publishing Open CASCADE Technology (OCCT) maintenance releases. The next OCCT maintenance release (version 7.5.3) is prepared.

The sources of Open CASCADE Technology 7.5.3 are available under the V7_5_3 tag in the OCCT repository.

This maintenance release fixes the following critical problems:

Since its publication as an open-source 3D modeling kernel, Open CASCADE Technology (OCCT) has become a backbone for numerous outstanding projects.  We are excited to announce that the marketplace for OCCT-based projects is launched on OCCT Development Portal!

Having received numerous requests from the open-source community Open Cascade decided to publish free trainings to ease access to Open CASCADE Technology (OCCT). Free presentations available on the recently renewed Development Portal cover Preliminaries, Geometry, and Topology topics.

Preliminaries subject aims at general OCCT-related problems. It focuses on general tasks like getting OCCT, its structure, building from sources, etc. In addition to Open CASCADE Technology overview, the training provides several performance tips and describes Draw Application functionality.
