GLOBE_3D is a real-time 3D engine. It features unconditionally portable sources (one set of sources for all platforms), real-time rendering (fast with a 3D hardware-accelerated graphics card), full eye movements and rotations, display of combinations of colors, materials, and textures, transparency, multiple area rendering with the portal technique (e.g. for inner scenes), collision detection, binary space partition (BSP), input-output of 3D objects or groups of objects linked to each other by portals, easy management of resources like textures (.bmp and .tga), BSP trees, and objects stored in .zip files, screenshots (.bmp) and video captures (.avi), multi-view support, and vectorized geometry support.
Py-Lepton is a high-performance, pluggable particle engine and API for Python. The engine is designed to be very flexible and does not rely on any other libraries directly. You can use it either with OpenGL (via pyglet or PyOpenGL), or with pygame by selecting the appropriate renderer. Examples are provided using pyglet and pygame. Note that this is in an alpha state, so expect the API to change somewhat in future releases.
