Explore Open CASCADE Technology-based research articles

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.

Open Cascade publishes OCCT-based research & science publications report

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 launches a marketplace for Open CASCADE Technology-based projects

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!

Open Cascade publishes free Open CASCADE Technology (OCCT) trainings

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.

OCCT PBR in WebGL 1.0

Forums: 

OCCT 7.5.0 has introduced PBR (physically-based rendering) metal-roughness material workflow in it’s real-time rendering engine. This feature brings more realistic rendering of metal materials and, which might be even more important, an industry-adopted material definition supported by many 3D applications (thanks to glTF 2.0 aka “JPEG for 3D” wide adoption).

PBR is considerably much more computationally intensive compared to old simplified approximations like Phong/Gouraud shading models, and involves a lot of optimization tricks to bring PBR to real-time. At the moment of development of PBR in OCCT, OpenGL 3.0 (released in ‘2008) with it’s mobile counterpart OpenGL ES 3.0 (specs released ‘2012) was considered a good baseline covering the majority of modern devices for PBR implementation. But what about WebGL?
