public class SegmentRenderer
extends Object

This class is intended only as a testing utility: it allows tube or ribbons segments to be drawn on-the-fly, rather than from OpenGL display lists, soley for the purpose of measure the performance advantage of caching geometry in OpenGL display lists.

Constructor Summary

SegmentRenderer()
Constructs a SegmentReferences object.

Method Summary

void	drawEndCap(GL gl) Draws the end cap for the last tube or ribbon segment that was drawn.

Method Detail

drawTube

public void drawTube(GL gl,
                     Segment s)

Draws the curved body of a tube segment and remembers info needed by any subsequent call to drawStartCap() or drawEndCap().

Parameters:

gl - the current GL object.

s - the segment to draw.

drawStartCap

public void drawStartCap(GL gl)

Draws the start cap for the last tube or ribbon segment that was drawn.

Parameters:

gl - the current GL object.

drawEndCap

public void drawEndCap(GL gl)

Draws the end cap for the last tube or ribbon segment that was drawn.

Parameters:

gl - the current GL object.

drawRibbon

public void drawRibbon(GL gl,
                       Segment s)

Draws the broad surfaces of a ribbon segment and remembers info needed by any subsequent call to drawThinSidesOfRibbon(), drawStartCap(), or drawEndCap().

Parameters:

gl - the current GL object.

s - the segment to draw.

drawThinSidesOfRibbon

public void drawThinSidesOfRibbon(GL gl)

Draws the thin sides for the last ribbon segment that was drawn.

Parameters:

gl - the current GL object.

setAllStackNumbersToDefault

public void setAllStackNumbersToDefault()

Sets all stacks numbers to the defaults defined in classes Tube and Ribbon (for loops, alpha-helices, and beta-strands).

setLoopTubeStacksToDefault

public void setLoopTubeStacksToDefault()

Sets the number of stacks for drawing a loop as a tube to the default value defined in class Tube. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setAlphaTubeStacksToDefault

public void setAlphaTubeStacksToDefault()

Sets the number of stacks for drawing an alpha-helix as a tube to the default value defined in class Tube. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setBetaTubeStacksToDefault

public void setBetaTubeStacksToDefault()

Sets the number of stacks for drawing a beta-strand as a tube to the default value defined in class Tube. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setLoopRibbonStacksToDefault

public void setLoopRibbonStacksToDefault()

Sets the number of stacks for drawing a loop as a ribbon to the default value defined in class Ribbon. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setAlphaRibbonStacksToDefault

public void setAlphaRibbonStacksToDefault()

Sets the number of stacks for drawing an alpha-helix as a ribbon to the default value defined in class Ribbon. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setBetaRibbonStacksToDefault

public void setBetaRibbonStacksToDefault()

Sets the number of stacks for drawing a beta-strand as a ribbon to the default value defined in class Ribbon. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

setLoopTubeStacks

public void setLoopTubeStacks(int stacks)

Sets the number of stacks for drawing a loop as a tube. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.

setAlphaTubeStacks

public void setAlphaTubeStacks(int stacks)

Sets the number of stacks for drawing an alpha-helix as a tube. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.

setBetaTubeStacks

public void setBetaTubeStacks(int stacks)

Sets the number of stacks for drawing a beta-strand as a tube. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.

setLoopRibbonStacks

public void setLoopRibbonStacks(int stacks)

Sets the number of stacks for drawing a loop as a ribbon. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.

setAlphaRibbonStacks

public void setAlphaRibbonStacks(int stacks)

Sets the number of stacks for drawing an alpha-helix as a ribbon. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.

setBetaRibbonStacks

public void setBetaRibbonStacks(int stacks)

Sets the number of stacks for drawing a beta-strand as a ribbon. If the argument is less than 1, the number of stacks will be set to 1. After setting this value, cacheSegmentGeometry() still needs to be called with the current GL object for the change to take effect.

Parameters:

stacks - the number of stacks.
