How can I contribute to the OpenSceneGraph?
Send changes as whole files to the osg-submissions mailing list along with an explanation of the changes. Do not send diffs or copy and paste extracts in emails, these will be simply disgarded, as they are too unreliable for review and merging. See MailingLists/SubmissionsProtocol for all the details. Alternatively you can post changes or submissions under the Community section of this website. This is particularly appropriate for complete new functionality such as NodeKits and plugins. After uploading your things to the website inform the osg-users or osg-submissions list of your entry.
