Member Function Documentation

add2DElement()

void SoFEMKit::add2DElement	(	const int	elementidx,
		const int32_t *	nodes,
		const int	layerindex = 0 )

Add a 2D element to the FEM. elementidx must be an unique index that can be used when setting the element color. nodes should contain the four node indices in the following order:

2______3

---—

0 1

layerindex can be used to specify the layer this element is in.

add3DElement()

void SoFEMKit::add3DElement	(	const int	elementidx,
		const int32_t *	nodes,
		const int	layerindex = 0 )

Add a 3D element to the FEM. elementidx should be an unique index that is used when setting element color. nodes should be an array of eight node indices, ordered like this:

5_______6 /| /| 4/_|____/7| z
| | | | | y | |1 _ |_|2 | / | / | / |/

|/ |/ ---—x

0 3

layerindex can be used to specify the layer this element is in.

addNode()

void SoFEMKit::addNode	(	const int	nodeidx,
		const SbVec3f &	xyz )

Add a node (vertex) to the FEM. nodeidx should be used to refer to this node (e.g. when setting the node color or when creating elements). Each node must have an unique nodeidx.

enableAllElements()

void SoFEMKit::enableAllElements

(

const SbBool

onoroff

)

Enable/disable all elements.

enableElement()

void SoFEMKit::enableElement	(	const int	elementidx,
		const SbBool	onoff )

Enable/disable the elementidx element.

enableElements()

void SoFEMKit::enableElements	(	const SbPlane &	plane,
		const SbBool	onoroff )

Enable/disable elements intersecting plane.

enableLayer()

void SoFEMKit::enableLayer	(	const int	layerindex,
		const SbBool	onoroff )

Enable/disable elements in the layerindex layer.

removeHiddenFaces()

void SoFEMKit::removeHiddenFaces

(

const SbBool

onoff

)

Turn on/off simple (but effective!) optimization that removes all faces that are hidden by other faces. Default is to remove hidden faces.

reset()

void SoFEMKit::reset

(

void

)

Reset the kit. All elements and nodes will be removed.

setElementColor()

void SoFEMKit::setElementColor	(	const int	elementidx,
		const SbColor &	color )

Sets the elementidx element color.

setNodeColor()

void SoFEMKit::setNodeColor	(	const int	nodeidx,
		const SbColor &	color )

Sets the nodeidx node color. Node color will override element colors if both the element color and a node color is set for any given node.

Member Data Documentation

ccw

SoSFBool SoFEMKit::ccw

Set to FALSE if you use a left handed coordinate system (or a coordinate system where the model matrix determinant is negative).
