Member Data Documentation

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.

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];
 }
