SG_INTRO(3) Library Functions Manual SG_INTRO(3) NAME SG_Intro -- Agar-SG introduction DESCRIPTION Agar-SG is a general-purpose scene-graph library built on top of the Agar library (https://libagar.org/). Agar-SG implements a compact and easily extensible object/scene graph representation, designed to sim- plify such tasks as real-time rendering and geometrical queries. SG LIBRARY The scene-graph library SG implements 3D rendering and geometry meth- ods. To use this library, link against `agar-sg-config --libs' SG(3) Base scene graph object. SG_Image(3) Textured polygon generated from an image surface. SG_Camera(3) Viewpoint in scene (tied to the SG_View(3) widget). SG_CgProgram(3) Vertex/fragment program in the Cg language. SG_Circle(3) Circle (reference geometry). SG_Geom(3) Base class for reference geometry objects. SG_Light(3) Light source. SG_Node(3) Base class for all elements of a SG(3) scene. SG_Object(3) Base class for polyhedral objects (using boundary representation). SG_Plane(3) Plane (reference geometry). SG_Point(3) Single point (reference geometry). SG_Polygon(3) Polygon (reference geometry). SG_PolyBall(3) Sphere (as polyhedral approximation). SG_PolyBox(3) Rectangular box (as polyhedron). SG_Program(3) Base class for vertex or fragment programs. SG_Rectangle(3) Rectangle (reference geometry). SG_Sphere(3) Sphere (reference geometry). SG_Texture(3) A texture compiled from a set of surfaces. May also be used to specify parameters for the fixed lighting model. SG_Triangle(3) Triangle (reference geometry). SG_View(3) Agar visualization widget for displaying a SG scene. SG_Voxel(3) Voxel object. SK LIBRARY The SK library implements dimensioned 2D sketching and constraint solv- ing. Sketches can contain sets of metric relations (i.e., distances, angles) and logical relations (i.e., coincidence, parallelism, tan- gency), and SK's attempts to find a solution using degree-of-freedom analysis. To use this library, link against `agar-sk-config --libs'. SK(3) Base sketch object. SK_View(3) Agar visualization widget for sketch objects. RG LIBRARY The RG library implements feature-based graphical tiles. To use this library, link against `agar-rg-config --libs'. RG(3) Feature-based pixel graphics. RG_Anim(3) Animation element RG_Feature(3) Feature framework RG_Pixmap(3) Pixmap image element RG_Sketch(3) Vector sketch element RG_Texture(3) Texture element RG_Tile(3) Base tile element RG_Tileview(3) Graphical edition and display widget MAP LIBRARY The MAP library extends RG to entire scenes / levels. To use this library, link against `agar-map-config --libs'. MAP(3) Base map object. MAP_Actor(3) Map object rendered dynamically. MAP_View(3) Editor and display widget.
