Class Silhouette

java.lang.Object
  org.proteinshader.graphics.Silhouette

public class Silhouette
extends Object

Uses jitter to repeatedly render a translucent black silhouette of a Drawable object for the purpose of antialiasing (smoothing jagged edges).

Field Summary

static boolean	DEFAULT Determines if translucent black silhouettes are used by default for antialiasing the dark edges of tubes or ribbons drawn with halftoning.
static double[]	JITTER_4 Holds (xPixels, yPixels) values for translating 4 times with jitter.

Constructor Summary

Silhouette(ShaderManager shaders)
Constructs a Silhouette object.

Method Summary

void	drawRibbon(GL gl, Segment s, SegmentListInfo info, boolean extraLines) Draws a translucent black silhoutte of a ribbon segment using jitter.
void	drawTube(GL gl, Segment s, SegmentListInfo info, boolean extraLines) Draws a translucent black silhoutte of a tube segment using jitter.

Constructor Detail

Silhouette

public Silhouette(ShaderManager shaders)

Constructs a Silhouette object.

The ShaderManager object used by class StructureToGraphics is needed so that the silhouette shader pair can be turned on right before rendering.

Parameters:

shaders - the shader manager used by StructureToGraphics.

drawTube

public void drawTube(GL gl,
                     Segment s,

Draws a translucent black silhoutte of a tube segment using jitter.

Parameters:

gl - the current GL object.

s - the Segment to draw.

info - holds names of OpenGL display lists for the Segment.

                       Segment s,
                       SegmentListInfo info,
                       boolean extraLines)

Draws a translucent black silhoutte of a ribbon segment using jitter.
