A mirror of releases is here.
A cross-platform OpenGL based lightweight scenegraph library
RenderTools is an OpenGL based scenegraph library in C++ for Windows, OSX and IOS supporting OpenGL|ES1.1, ES2.0, OpenGL1.5 and up to the latest version (currently 4.2). It allows the developer to easily (de)serialize a scenegraph to-and-from xml, create renderbuffers, framebuffers, samplers, vertexbuffers etc. and cross-reference those items. RenderTools allows you to completely specify an application, its resources, viewcontrollers and its renderpasses in one single xml. GraphNodes such as RelationalNode, RenderNode, and TransformNode can be used to create a complex hierarchy for rendering. Both update and render calls can selectively include or exclude specific components such as geometric details or lighting or texturing.
Project is to maintain the open source tree for the Azusa Derived Distribution Edition of the SIO2 SDK v1.4 Game Engine Free Ed., previously distributed by sio2interactive.com in the book by Tony Mullen, "3D for iPhone Apps with Blender and SIO2."
The Objective-C Interactive Simulation Abstraction Layer
SimKit(because GameKit was taken) is designed to allow quick and easy cross platform abstraction away from platform dependant drawing and physics libraries. The APIs provide a generic way to make common calls for drawing, animating, and otherwise manipulating 3D entities, as well as shading and texture information.
