Hi all,
I'll try to explain my problem :
I've got a mesh in 3D with about 200 000 samples and 1 000 000 tetras.
I apply the method used in Delaunay.main (line 955...) :
DelaunayCadoe delaun = new DelaunayCadoe(samples,tetra);
// The same as DelaunayCustom but without copy, with debug and
// 4 edges (6 in DelaunayCustom)
Irregular3DSet iset = new
Irregular3DSet(xyz,samples,null,null,null,delaun);
int numEdges = delaun.NumEdges;
Gridded3DSet[] gsp = new Gridded3DSet[numEdges];
int[] e0 = {0, 0, 1, 2};
int[] e1 = {1, 3, 2, 3};
for (int i=0; i<numEdges; i++) gsp[i] = null;
for (int i=0; i<delaun.Edges.length; i++) {
int[] trii = delaun.Tri[i];
int[] edgesi = delaun.Edges[i];
for (int j=0; j<4; j++) {
if (gsp[edgesi[j]] == null) {
float[][] pts = new float[3][2];
float[] p0 = pts[0];
float[] p1 = pts[1];
float[] p2 = pts[2];
int tp0 = trii[e0[j]];
int tp1 = trii[e1[j]];
p0[0] = samples[0][tp0];
p1[0] = samples[1][tp0];
p2[0] = samples[2][tp0];
p0[1] = samples[0][tp1];
p1[1] = samples[1][tp1];
p2[1] = samples[2][tp1];
gsp[edgesi[j]] = new Gridded3DSet(xyz, pts, 2);
}
}
}
UnionSet tet = new UnionSet(xyz, gsp);
final DataReference tetref = new DataReferenceImpl("tet");
tetref.setData(tet);
The problem is that this part of code and the display of this mesh, use
about 755M of Memory...
As i'm quite new in java, I don't know which element is so huge (There
is no sizeof() as in C ?).
how can I optimize this code ?
Any comments may be very helpful...
