Open Source 3D Rendering Software

The Irrlicht Engine is an open source high performance realtime 3D engine written and usable in C++. It is completely cross-platform, using D3D, OpenGL and its own software renderers.

for the latest release see either - https://github.com/OGRECave/ogre - https://github.com/OGRECave/ogre-next An efficient, object-oriented hardware accelerated 3D engine. It abstracts the differences between APIs and platforms and allows scene-oriented coding through an easy to use object model. Adaptable to multiple scene types (indoor, outdoor, whatever)

TacitPixel is a scalable C++ framework for building application prototypes for interactive collaborative VR/AR applications. It provides a number of features that make prototyping fast and portable. TacitPixel is the successor of the TAP and Twisted Pair engines.

Over 75 C++ function for working with vectors, matrix and quaternions. Inside the package there is no cycles, if's, classes or structures. Ideal for designing 3D engines. Headlines of functions are intuitive. For each headline there is a one line comment in Russian. Matrix are presented in OpenGL form 0 4 8 12 1 5 9 13 2 6 10 14 3 7 11 15 Now we are working on adding 50+ more functions for processing the planes, splines, bezier curves and interpolation methods.
