public abstract class DrawFacetAbstract

extends Object

implements DrawFacet, Serializable

Abstract class that forms a basis for the DrawFacet??? classes. It contains polygon methods that draw, erase, or fill facets in various ways. The subclasses implement the abstract draw method and call the polygon methods in various ways to implement the look required (determined by the meshed, shaded, contoured, and zoned attributes).

setDrawGrid

public void setDrawGrid(com.klg.jclass.chart3d.DrawGrid drawGrid)

Sets the drawGrid parent.

Specified by:

setDrawGrid in interface DrawFacet

Parameters:

drawGrid -

public void setGC(Graphics gc)

Sets the graphics context used to draw this facet.

Specified by:

setGC in interface DrawFacet

Parameters:

public Graphics getGC()

Gets the graphics context used to draw this facet.

Specified by:

getGC in interface DrawFacet

setDrawMeshLine

public void setDrawMeshLine(boolean drawMeshLine)

Sets whether the mesh line gets drawn for this facet.

Specified by:

setDrawMeshLine in interface DrawFacet

Parameters:

drawMeshLine -

getDrawMeshLine

public boolean getDrawMeshLine()

polyOutline

public void polyOutline(int[] xPoints,
                        int[] yPoints,
                        int n,
                        int holeCode,
                        int x,
                        int y)

Draws the outline of the polygon represented by xPoints and yPoints. This will either be a 3 or 4 sided polygon depending on whether the original facet has been triangularized.

Specified by:

polyOutline in interface DrawFacet

Parameters:

xPoints -

yPoints -

n -

holeCode -

x -

y -

polyFilled

public void polyFilled(int[] xPoints,
                       int[] yPoints,
                       int n,
                       int holeCode)

Fills the polygon represented by xPoints and yPoints. This will either be a 3 or 4 sided polygon depending on whether the original facet has been triangularized.

Specified by:

polyFilled in interface DrawFacet

Parameters:
