Field Detail

sizes

public final SoMFInt32 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.

vertices

public final SoMFVec3d 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];
 }
