public class Quality
extends Object

Provides a structure for setting the rendering quality, i.e., the tradeoff between computation speed, and graphic quality. Following mode have an impact on the way the View makes its GL2 initialization. The Quality may also activate an AbstractOrderingStrategy algorithm that enables clean alpha results. Fastest: - No transparency, no color shading, just handle depth buffer. Intermediate: - include Fastest mode abilities - Color shading, mainly usefull to have interpolated colors on polygons. Advanced: - include Intermediate mode abilities - Transparency (GL2 alpha blending + polygon ordering in scene graph) Nicest: - include Advanced mode abilities - Anti aliasing on wires Toggling rendering model: one may either choose to have a repaint-on-demand or repaint-continuously model. Setting isAnimated(false) will desactivate a the Animator updating the choosen ICanvas implementation. setAutoSwapBuffer(false) will equaly configure the ICanvas.

isDepthActivated

public boolean isDepthActivated()

setDepthActivated

public void setDepthActivated(boolean depthActivated)

isAlphaActivated

public boolean isAlphaActivated()

setAlphaActivated

public void setAlphaActivated(boolean alphaActivated)

isSmoothColor

isDisableDepthBufferWhenAlpha

public boolean isDisableDepthBufferWhenAlpha()

setDisableDepthBufferWhenAlpha

setAnimated

public void setAnimated(boolean isAnimated)

isAutoSwapBuffer

public boolean isAutoSwapBuffer()

setAutoSwapBuffer

public void setAutoSwapBuffer(boolean isAutoSwapBuffer)

isPreserveViewportSize

public boolean isPreserveViewportSize()

Used by a Canvas to setup pixel ratio. This might be used to avoid mouse pointer errors on Retina display as most canvas implementation will perform : if(quality.isPreserveViewportSize()) setPixelScale(new float[] { ScalableSurface.IDENTITY_PIXELSCALE, ScalableSurface.IDENTITY_PIXELSCALE });

setPreserveViewportSize

public void setPreserveViewportSize(boolean preserveViewportSize)
