Member Data Documentation

sizes

SoMFInt32 SoSegmentChain::sizes

Array containing the number connected vertices in each segment chain.

The size of the array is the number of chains.

A chain with n connected vertices has (n-1) segment. A chain cannot have less than 2 vertices.

Definition at line 57 of file SoSegmentChain.h.

vertices

SoMFVec3d SoSegmentChain::vertices

Ordered list of vertices used in all the segment chains.

Here is an example on how to iterate over each vertices of each chain.

int indexAccumulator = 0;
for (int chainIndex=0; chainIndex<sizes.getNum(); ++chainIndex)
{
  for (int vertexIndex=0; vertexIndex<sizes[chainIndex]; ++vertexIndex)
  {
    fprintf(stdout,"chain %d - vertices %d = (%.3g %.3g %.3g)\n",
         chainIndex, vertexIndex,
         vertices[indexAccumulator+vertexIndex][0],
         vertices[indexAccumulator+vertexIndex][1],
         vertices[indexAccumulator+vertexIndex][2]
    );
  }
  indexAccumulator += sizes[chainIndex];
}
