DESCRIPTION

61       This  node  represents  a sphere. By default, the sphere is centered at
62       the origin and has a radius of 1. The sphere is transformed by the cur‐
63       rent  cumulative  transformation and is drawn with the current lighting
64       model, drawing style, material, and geometric complexity.
65
66       A sphere does not have faces or parts. Therefore,  the  sphere  ignores
67       material  and  normal bindings, using the first material for the entire
68       sphere and using its own normals.  When  a  texture  is  applied  to  a
69       sphere,  the  texture covers the entire surface, wrapping counterclock‐
70       wise from the back of the sphere. The texture has a seam at the back on
71       the yz-plane.

FIELDS

74     SoSFFloat           radius
75          Radius of sphere. This must be greater than 0.

77

METHODS

79                         SoSphere()
80          Creates a sphere node with default settings.
81
82     static SoType       getClassTypeId()
83          Returns type identifier for this class.

ACTION BEHAVIOR

87       SoGLRenderAction
88          Draws  sphere  based  on the current coordinates, materials, drawing
89          style, and so on.
90
91     SoRayPickAction
92          Intersects the ray with the  sphere.  No  details  are  created  for
93          intersections.
94
95     SoGetBoundingBoxAction
96          Computes the bounding box that encloses the sphere.
97
98     SoCallbackAction
99          If  any triangle callbacks are registered with the action, they will
100          be invoked  for  each  successive  triangle  that  approximates  the
101          sphere.
