computeBBox()

void SoFCMeshNode::computeBBox ( SoAction *  action, SbBox3f &  box, SbVec3f &  center  )

protectedvirtual

Sets the bounding box of the mesh to box and its center to center.

createTriangleDetail()

SoDetail * SoFCMeshNode::createTriangleDetail ( SoRayPickAction *  action, const SoPrimitiveVertex *  v1, const SoPrimitiveVertex *  v2, const SoPrimitiveVertex *  v3, SoPickedPoint *  pp  )

protectedvirtual

If the number of triangles exceeds MaximumTriangles 0 is returned.

This means that the client programmer needs to implement itself to get the index of the picked triangle. If the number of triangles doesn't exceed MaximumTriangles SoShape::createTriangleDetail() gets called. Against the default OpenInventor implementation which returns 0 as well Coin3d fills in the point and face indices.

References MaximumTriangles.

generatePrimitives()

void SoFCMeshNode::generatePrimitives ( SoAction *  action )

protectedvirtual

Sets the point indices, the geometric points and the normal for each triangle.

If the number of triangles exceeds MaximumTriangles then only a triangulation of a rough model is filled in instead. This is due to performance issues.

getPrimitiveCount()

void SoFCMeshNode::getPrimitiveCount ( SoGetPrimitiveCountAction *  action )

protectedvirtual

Adds the number of the triangles to the SoGetPrimitiveCountAction.

GLRender()

void SoFCMeshNode::GLRender ( SoGLRenderAction *  action )

protectedvirtual

Either renders the complete mesh or only a subset of the points.

References Gui::SoFCInteractiveElement::get(), and MaximumTriangles.

initClass()

void SoFCMeshNode::initClass ( void  )

static

readInstance()

SbBool SoFCMeshNode::readInstance ( SoInput *  in, unsigned short  flags  )

protectedvirtual

Reads in the mesh node from the input stream.

References MeshCore::MeshKernel::Adopt().

setMesh()

void SoFCMeshNode::setMesh

(

const Mesh::MeshObject *

mesh

)

Sets the mesh.

write()

void SoFCMeshNode::write ( SoWriteAction *  action )

virtual

Writes out the mesh node.
