Method Detail

setMesh3DViewGeneratorQuality

public void setMesh3DViewGeneratorQuality(double quality)

Sets this Mesh3DViewGenerator quality.
quality is the pixel precision to use for view generation

Parameters:

quality - quality

getMesh3DViewGeneratorQuality

public double getMesh3DViewGeneratorQuality()

Gets this Mesh3DViewGenerator current quality.
quality is the pixel precision used for view generation

Returns:

current quality

generateForView

public void generateForView(double x,
                            double y,
                            double z,
                            double tx,
                            double ty,
                            double tz,
                            double focus,
                            double viewWidth)

Generate a (LOD) Face3DList for a given view point using the current view generator quality.
View point must be given in object space

Parameters:

x - view point x in object space

y - view point y in object space

z - view point z in object space

tx - view point target x in object space

ty - view point target y in object space

tz - view point target z in object space

focus - focal length to use

viewWidth - screen width in pixels

getNbViewFaces

public int getNbViewFaces()

Gets number of Face3D generated by the last call to generateForView.

Returns:

number of Face3D that was generated for last call to generateForView

getViewFace3DList

public IFace3DList getViewFace3DList()

Gets Face3DList generated by the last call to generateForView.

Returns:

Face3DList that was generated for last call to generateForView

setFarClip

public void setFarClip(double farClip)

Sets far clipping value for view generation.

Parameters:

farClip - far clipping value

setNearClip

public void setNearClip(double nearClip)

Sets near clipping value for view generation.

Parameters:

nearClip - near clipping value
