Member Function Documentation

boolean edu.tum.cs.vis.model.util.Triangle.addNeighbor	(	Triangle	neighbor,
		Lock	lock
	)		`[inline]`

Add a neighbor to the neighbors list. If list contains already neighbor this method doesn't add it again. If not, the neighbor will be added and this instance will be added as a neighbor in the given neighbor instance.

Parameters:

neighbor	neighbor to add.
lock	Mutex lock to avoid multithreading issues. This object should be the same for all calling threads. Used to synchronizes adding a neighbor to the triangle

Returns:: true if neighbor is really a neighbor of this triangle and it was successfully added.

Definition at line 146 of file Triangle.java.

boolean edu.tum.cs.vis.model.util.Triangle.calculateNormalVector ( ) [inline]

Calculate and set normal vector for triangle

Returns:: true if vector successfully calculated

Definition at line 377 of file Triangle.java.

void edu.tum.cs.vis.model.util.Triangle.draw	(	PGraphics	g,
		DrawSettings	drawSettings
	)		`[inline]`

Draw the triangles onto the applet.

Parameters:

g	Graphics to draw on
drawSettings	override the draw color, texture (and other settings). Draw whole object in the given color if != null

Definition at line 200 of file Triangle.java.

float edu.tum.cs.vis.model.util.Triangle.getArea ( ) [inline]

returns the area of the triangle in 3d space. Unit is the same as you draw the triangle.

Returns:: the area in drawing unit.

Definition at line 278 of file Triangle.java.

Point3f edu.tum.cs.vis.model.util.Triangle.getCentroid ( ) [inline]

Get centroid of triangle
