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 simplify such tasks as real-time rendering and geometrical queries. SG LIBRARY The scene-graph library SG implements 3D rendering and geometry methods. 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 repre- sentation). 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 solving. Sketches can contain sets of metric relations (i.e., distances, angles) and logical relations (i.e., coincidence, parallelism, tangency), and SK's at- tempts 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.
