I set up this site for global communication among individuals, NPOs, and NGOs in science, art, music, and education for these subjects on February 13, 2021. Under this project, I developed a self-hosted site providing open-source software (OSS) services, i.e., three video conferencing services, two application-sharing services, a learning management service, and a chat service, which I named "Micro-VPC."[1] In these services, "Collaborative RDS"[2] enables multi-user interactive operation by user management with privilege separation and restriction on RDS. For the project's third year, I would like to consider how the users can use OSS to improve communication through practical education, especially in 3D CAD and 3D CG online teachings. Besides, I will continue to release technical reports for software customization, application of software to education, and education content, as shown on the Activities page on this site. Please ask me on Facebook by the following link for more details.
