public class PlaneRender
extends VolumeCanvas3D
implements MouseMotionListener, MouseListener, MouseBehaviorCallback

Class PlaneRender: renders a single dimension of the ModelImage data as a texture-mapped polygon. The PlaneRender class keeps track of whether it is rendering the Axial, Sagital, or Coronal view of the data. Surfaces are displayed as the intersection of the ModelTriangleMesh with the rendered z-slice.

initAxes

private void initAxes()

Initializes the Axis labels based on the ModelImage orientation. Axes are displayed with 3D text objects and arrows drawn as polygons. They are colored and labeled to match the axes they represent.

processLeftMouseDrag

private void processLeftMouseDrag(MouseEvent kEvent)

Dragging the mouse with the left-mouse button held down changes the positions of the X and Y cross bars, and therefor the ZSlice positions of the associated PlaneRender objects and the TriPlanar Surface. The new positions are calculated and passed onto the parent frame.

Parameters:

kEvent - the mouse event generated by a mouse drag

setCenter

public void setCenter(WildMagic.LibFoundation.Mathematics.Vector3f center)

setCenter sets the cursor and slice position for this PlaneRender object, based on the 3D location of the three intersecting ModelImage planes.

Parameters:

center - the 3D center in FileCoordinates of the three intersecting ModelImage planes.

getCenter

public javax.vecmath.Vector3f getCenter()

Returns the current center point of the 3 intersecting ModelImage planes in FileCoordinates.

Returns:

the current volume center point in FileCoordinates

processRightMouseDrag

private void processRightMouseDrag(MouseEvent kEvent)

If the right mouse button is pressed and dragged. processRightMouseDrag updates the HistoLUT window and level (contrast and brightness)

Parameters:

kEvent - the mouse event generated by a mouse drag

setOrientation

private void setOrientation()

Based on the orientaion of the ModelImage, sets up the index parameters, m_aiLocalImageExtents[0], m_aiLocalImageExtents[1], and m_aiLocalImageExtents[2], the drawing colors for the z box, x and y bars, and the invert flags.

Once setup everything is rendered into an x,y plane where x,y may be any of the original x,y, or z dimensions in the original ModelImage.

updateViewScreenScale

private void updateViewScreenScale(javax.media.j3d.Transform3D kTransform)

This function calculates the scale factor for zooming in parallel projection. The scenario is to calculate the distance between the origin boxframe center and tranformed boxframe center. This distance is used to compute the screen scale factor.

Parameters:

kTransform - The tranformation matrix from tranformChanged().

writeTexture

private void writeTexture(boolean bForceShow)

Stores the ModelImage data as an array of texture maps, with LUT or RGBA color lookup:.
