GeomRep
Interface GeomObject

All Known Implementing Classes:

Ellipsoid, TriangulatedObject

public interface GeomObject

Interface GeomObject specifies the interface of a geometric object that forms a part of the Scene. The interface is implemented by concrete geometric object classes like Ellipsoid (general case of a sphere), TriangulatedObject, Cuboid etc.

Method Detail

DrawWireFrame

void DrawWireFrame(DrawingCanvasInterface canvas,
                   java.awt.Graphics g,
                   float[] transMatrix)

Draw the wire frame model for object. Transformation matrix captures all the transformation related information (for instance, if the view is perspective or axonometric).

Parameters:

canvas - Instance of DrawingCanvas (@see GridView.DrawingCanvas)

g - Graphics instance to draw to.

transMatrix - Transformation matrix

DrawSurface

void DrawSurface(DrawingCanvasInterface canvas,
                 java.awt.Graphics g,
                 float[] transMatrix)

Draw the surface model for object. Transformation matrix captures all the transformation related information (for instance, if the view is perspective or axonometric).

Parameters:

canvas - Instance of DrawingCanvas (@see GridView.DrawingCanvas)

g - Graphics instance to draw to.

transMatrix - Transformation matrix

DrawSurfaceOnly

void DrawSurfaceOnly(DrawingCanvasInterface canvas,
                     java.awt.Graphics g,
                     float[] transMatrix)

Draw only the surface model for object, without edges. Transformation matrix captures all the transformation related information (for instance, if the view is perspective or axonometric).

Parameters:

canvas - Instance of DrawingCanvas (@see GridView.DrawingCanvas)

g - Graphics instance to draw to.

transMatrix - Transformation matrix

DrawCameraImage

void DrawCameraImage(DrawingCanvasInterface canvas,
                     java.awt.Graphics g,
                     float[] transMatrix,
                     boolean onlySurface)

Draws the surface model with camera positioned at (X, Y, Z). Camera position, perspective proj etc are all baked into transMatrix (transformation matrix)

DrawCrinkleCut

void DrawCrinkleCut(DrawingCanvasInterface canvas,
                    java.awt.Graphics g,
                    float[] plane,
                    float[] transMatrix)

Draw the object face cut by the crinkle cut plane. Transformation matrix captures all the transformation related information (for instance, if the view is perspective or axonometric). Coefficients describing the cut plane are: plane[0]*X + plane[1]*Y + plane[2]*Z + plane[3] = 0.

Parameters:

canvas - Instance of DrawingCanvas (@see GridView.DrawingCanvas)

g - Graphics instance to draw to.

plane - Coefficients describing the cut plane are: plane[0]*X + plane[1]*Y + plane[2]*Z + plane[3] = 0.
