SIG Libraries

SIG is currently organized in 4 libraries:

• sig: core graphics classes
• sigogl: OpenGL related classes
• sigos: operating system interface
• sigkin: skeleton and motion classes

Modules in Libraries

The .h and .cpp files in each library are divided in modules identified by the first 2 letters of each file. The modules for each library are:

• gs (sig): generic graphics and system classes, examples: GsVec, GsMat, GsOuput, GsArray
• sn (sig): scene graph nodes, examples: SnModel, SnLines, SnTransform
• sa (sig): scene graph actions, examples: SaBBox, SaRenderMode
• cd (sig): interface to external collision detectors, examples: CdImplementation, CdManager
• wsi (sigos): OS-specific window system interface, examples: wsi_get_ogl_procedure()
• gl (sigogl): OpenGL-related functions and classes, examples: GlProgram, GlTexture
• glr (sigogl): Scene node renderers based on OpenGL, examples: GlrMode, GlrLines, GlrText
• ui (sigogl): OpenGL-rendered GUI classes, examples: UiButton, UiStyle, UiManager
• ws (sigogl): Window system classes, examples: WsWindow, WsViewer
• kn (sigkin): Kinematics of articulated structures, examples: KnJoint, KnSkeleton, KnMotion

Naming Conventions

SIG follows a simple yet consistent naming convention which is briefly described in gs.h. It has proven to be effective over the many years it has been used.
