createBuffer	back to summary
public FloatBuffer createBuffer(float radius, int slices, int stacks) 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 glu.quadricOrientation), 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 glu.quadricTexture), 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.

setDrawStyle	back to summary
public void setDrawStyle(int drawStyle) specifies the draw style for quadrics. The legal values are as follows: GLU.FILL: Quadrics are rendered with polygon primitives. The polygons are drawn in a counterclockwise fashion with respect to their normals (as defined with glu.quadricOrientation). GLU.LINE: Quadrics are rendered as a set of lines. GLU.SILHOUETTE: Quadrics are rendered as a set of lines, except that edges separating coplanar faces will not be drawn. GLU.POINT: Quadrics are rendered as a set of points. Parameters drawStyle:int The drawStyle to set

setDrawStyle

back to summary

public void setDrawStyle(int drawStyle)

specifies the draw style for quadrics.

The legal values are as follows:

GLU.FILL: Quadrics are rendered with polygon primitives. The polygons are drawn in a counterclockwise fashion with respect to their normals (as defined with glu.quadricOrientation).

GLU.LINE: Quadrics are rendered as a set of lines.

GLU.SILHOUETTE: Quadrics are rendered as a set of lines, except that edges separating coplanar faces will not be drawn.

GLU.POINT: Quadrics are rendered as a set of points.

Parameters

drawStyle:int: The drawStyle to set

setNormals	back to summary
public void setNormals(int normals) specifies what kind of normals are desired for quadrics. The legal values are as follows: GLU.NONE: No normals are generated. GLU.FLAT: One normal is generated for every facet of a quadric. GLU.SMOOTH: One normal is generated for every vertex of a quadric. This is the default. Parameters normals:int The normals to set

setNormals

back to summary

public void setNormals(int normals)

specifies what kind of normals are desired for quadrics. The legal values are as follows:

GLU.NONE: No normals are generated.

GLU.FLAT: One normal is generated for every facet of a quadric.

GLU.SMOOTH: One normal is generated for every vertex of a quadric. This is the default.

Parameters

normals:int: The normals to set

setOrientation	back to summary
public void setOrientation(int orientation) specifies what kind of orientation is desired for. The orientation values are as follows: GLU.OUTSIDE: Quadrics are drawn with normals pointing outward. GLU.INSIDE: Normals point inward. The default is GLU.OUTSIDE. Note that the interpretation of outward and inward depends on the quadric being drawn. Parameters orientation:int The orientation to set

setOrientation

back to summary

public void setOrientation(int orientation)

specifies what kind of orientation is desired for. The orientation values are as follows:

GLU.OUTSIDE: Quadrics are drawn with normals pointing outward.

GLU.INSIDE: Normals point inward. The default is GLU.OUTSIDE.

Note that the interpretation of outward and inward depends on the quadric being drawn.

Parameters

orientation:int: The orientation to set

setTextureFlag	back to summary
public void setTextureFlag(boolean textureFlag) specifies if texture coordinates should be generated for quadrics rendered with qobj. If the value of textureCoords is true, then texture coordinates are generated, and if textureCoords is false, they are not.. The default is false. The manner in which texture coordinates are generated depends upon the specific quadric rendered. Parameters textureFlag:boolean The textureFlag to set

setTextureFlag

back to summary

public void setTextureFlag(boolean textureFlag)
