We are proud to announce the release of Matali Physics 5.5 a crucial change in the development of Matali Physics engine and a significant step on the road to the sixth main version. As of version 5.5, Matali Physics becomes an advanced 3d physics environment, and the physics engine developed so far, renamed to Matali Physics Core becomes the "heart" of the new environment. Matali Physics brand now means the entire physics environment, not just the physics engine. The introduced change preserves and strengthens the previous modular formula of our solution, extends its applications as well as brings to life our idea of a "fully dynamic scene".
