Tellusim Core SDK Posted On GitHub As C++ SDK For Graphics / Compute

Written by Michael Larabel in Programming on 18 October 2025 at 09:09 AM EDT. 13 Comments
For those evaluating new options for high performance, cross-platform graphics and/or compute for simulations and other purposes, Tellusim Technologies has made their Tellusim Core SDK publicly available via GitHub.

Tellusim as a reminder is what powers the demanding GravityMark graphics benchmark. Alexander Zapryagaev who was a co-founder of the well known Unigine Corp and Unigine Engine developer is the one that went on to form Tellusim Technologies.

The Tellusim Core SDK is self-described as:
"Tellusim Core SDK is the foundational layer of the Tellusim Engine, providing low-level functionality for high-performance graphics, compute, and application development across multiple platforms and devices. It offers a unified C++ API designed to abstract hardware and OS differences, enabling developers to write portable and scalable applications in graphics, simulation, visualization, and AI.

The SDK includes comprehensive support for meshes, images, user interfaces, and GPU-accelerated algorithms such as radix sort, bounding volume hierarchies (BVH), fast Fourier transforms (FFT), and GPU-driven computational graph framework for machine learning and advanced data processing.

In addition to C++, the SDK provides bindings and interoperability for other languages such as C#, Rust, Swift, and Python, making it suitable for use in native mobile and desktop applications as well as game and graphics engines."

The source to the Tellusim Core SDK is available but it's not a proper open-source solution, before getting too excited. The important notes of the Tellusim Core SDK license include:
"* Tellusim Core SDK is free for education
* Tellusim Core SDK is free for companies with annual revenue less than USD $200,000
* Tellusim Core SDK may be used for evaluation purposes, limited to testing, learning, and other non-commercial experimentation
* Any other use, including commercial or production deployment, requires a separate negotiated license with Tellusim Technologies Inc."
