A variety of them can be created using these functions. g3d_primitive_cubeG3DObject* g3d_primitive_cube (G3DFloat width, G3DFloat height, G3DFloat depth, G3DMaterial *material); Generates an object containing a box. It is deprecated and now a wrapper for g3d_primitive_box(). width : the width of the box height : the height of the box depth : the depth of the box material : the material to use for all faces Returns : the box object g3d_primitive_boxG3DObject* g3d_primitive_box (G3DFloat width, G3DFloat height, G3DFloat depth, G3DMaterial *material); Generates an object containing a box. width : the width of the box height : the height of the box depth : the depth of the box material : the material to use for all faces Returns : the box object g3d_primitive_box_strip_2dG3DObject* g3d_primitive_box_strip_2d (guint32 vcnt, gdouble *vdata, gdouble height, gdouble width, G3DMaterial *material); Generates a strip of box segments defined by corner center points using two-dimensional data (x/z plane). vcnt : number of control points vdata : 2-dimensional control point data (2 * vcnt * gdouble) height : height of resulting strip (y component) width : width of strip (corner diameter) material : material to use for faces Returns : strip object g3d_primitive_meshG3DObject* g3d_primitive_mesh (guint32 m, guint32 n, gboolean wrap_m, gboolean wrap_n, G3DMaterial *material); Generate a mesh consisting of m * n vertices. The vertex data is initialized with (0.0, 0.0, 0.0) and has to be set to something useful. m : number of vertices in m direction n : number of vertices in n direction wrap_m : wrap around in m direction wrap_n : wrap around in n direction material : material to use for faces Returns : mesh object g3d_primitive_cylinderG3DObject* g3d_primitive_cylinder (G3DFloat radius, G3DFloat height, guint32 sides, gboolean top, gboolean bottom, G3DMaterial *material); Generates an object containing a cylinder. radius : the radius of the cylinder height : the height of the side faces sides : number of side faces (number of circle segments) top : add top faces bottom : add bottom faces material : material to use for faces Returns : cylinder object g3d_primitive_tubeG3DObject* g3d_primitive_tube (G3DFloat r_in, G3DFloat r_out, G3DFloat height, guint32 sides, gboolean top, gboolean bottom, G3DMaterial *material); Generates an object containing a tube (a cylinder with a hole). r_in : inner radius r_out : outer radius height : the height of the side faces sides : number of side faces (number of circle segments) top : add top faces bottom : add bottom faces material : material to use for faces Returns : tube object g3d_primitive_sphereG3DObject* g3d_primitive_sphere (G3DFloat radius, guint32 vseg, guint32 hseg, G3DMaterial *material); Generates an object containing a sphere. radius : radius vseg : number of vertical segments hseg : number of horizontal segments material : material to use for faces Returns : sphere object
