Quadric

public Quadric()

Constructor for Quadric.

Method Detail

normal3f

protected void normal3f(float x,
            float y,
            float z)

Call glNormal3f after scaling normal to unit length.

Parameters:

x -

y -

z -

setDrawStyle

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 - The drawStyle to set

setNormals

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 - The normals to set

setOrientation

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 - The orientation to set

setTextureFlag

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 - The textureFlag to set

getDrawStyle

public int getDrawStyle()

Returns the drawStyle.

Returns:

int

getNormals

public int getNormals()

Returns the normals.

Returns:

int

getOrientation

public int getOrientation()

Returns the orientation.

Returns:

int

getTextureFlag

public boolean getTextureFlag()

Returns the textureFlag.

Returns:

boolean

TXTR_COORD

protected void TXTR_COORD(float x,
              float y)

sin

protected float sin(float r)

cos

protected float cos(float r)
