oce (Open Cascade community Edition) is a fork of the Open Cascade 3D c++ modeling library. This project aims at gathering patches/changes/improvements from the OCC community. Official OCCT documentation and sources are available at https://dev.opencascade.org/

There are 4 main branches:

1. upstream/master is a mirror of the official OpenCascade git repository master branch. Both are updated about once a week. Note that you need to sign a CLA to access the upstream repository, even in read only mode, otherwise you only have a gitweb access to the source. First commit is the snapshot of the 7.4.0 release.

2. oce/patches contains community patches. oce/patches is rebased on top of upstream/master each time it is updated. oce/patches is set as the default branch in the github project settings.

3. azure-ci contains programs to build oce on a MS Azure pipeline. azure-ci is

4. official-upstream-packages is an empty branch (dos not contain any source), also known as an orphan branch. It is a container for copies of official source and binary packages. This allows anonymous download of official packages, whereas upstream webstie requires to be logged in to start any download.

Tags/Releases:

Since official 7.4.0, all upstream tags are mirrored using the upstream/ prefix (e.g. the 7_4_0p1 upstream tag is available as upstream/7_4_0p1 on this repository).

oce has not released any recent version after upstream 7.5.0 was released.
