gluSphere 函数解析(OpenGL画球体)

C语言中定义： void gluSphere(GLUquadricObj *qobj, 　　GLdouble radius, 　　GLint slices, 　　GLint stacks) 参数： qobj：二次曲目对象（GLUquadricObj * qobj，初始化：cylinder_obj= gluNewQuadric();） radius ：球半径； slices： Z轴方向片数，经度方向； stacks： z轴方向片数，维度方向。 描述： gluSphere draws a sphere of the given radius centered around the origin. The sphere is subdivided around the z axis into slices and along the z axis into stacks (similar to lines of longitude and latitude). 　　If the orientation is set to GLU_OUTSIDE (with gluQuadricOrientation), then any normals generated point away from the center of the sphere. Otherwise, they point toward the center of the sphere. 　　If texturing is turned on (with gluQuadricTexture), then texture coordinates are generated so that t ranges from 0.0 at z = -radius to 1.0 at z = radius (t increases linearly along longitudinal lines), and s ranges from 0.0 at the +y axis, to 0.25 at the +x axis, to 0.5 at the -y axis, to 0.75 at the -x axis, and back to 1.0 at the +y axis. 您正在看的文章来自益学网OpenGL WebGL论坛 http://3d.enqm.net,原文地址:http://3d.enqm.net/read-htm-tid-47.html
