C++ (Cpp) rtcNewLineSegments Examples

Example #1

File: viewer_stream_device.cpp Project: dkoerner/embree

unsigned int convertLineSegments(ISPCLineSegments* mesh, RTCScene scene_out)
{
  unsigned int geomID = rtcNewLineSegments (scene_out, RTC_GEOMETRY_STATIC, mesh->numSegments, mesh->numVertices, mesh->v2 ? 2 : 1);
  rtcSetBuffer(scene_out,geomID,RTC_VERTEX_BUFFER,mesh->v,0,sizeof(Vertex));
  if (mesh->v2) rtcSetBuffer(scene_out,geomID,RTC_VERTEX_BUFFER1,mesh->v2,0,sizeof(Vertex));
  rtcSetBuffer(scene_out,geomID,RTC_INDEX_BUFFER,mesh->indices,0,sizeof(int));
  return geomID;
}

Example #2

File: viewer_anim_device.cpp Project: nyue/embree

 unsigned int convertLineSegments(ISPCLineSegments* mesh, RTCScene scene_out)
 {
   /* if more than a single timestep, mark object as dynamic */
   RTCGeometryFlags object_flags = mesh->numTimeSteps > 1 ? RTC_GEOMETRY_DYNAMIC : RTC_GEOMETRY_STATIC;
   /* create object */
   unsigned int geomID = rtcNewLineSegments (scene_out, object_flags, mesh->numSegments, mesh->numVertices, mesh->numTimeSteps);
   /* generate vertex buffer */
   Vec3fa* vertices = (Vec3fa*) rtcMapBuffer(scene_out,geomID,RTC_VERTEX_BUFFER);
   for (size_t i=0;i<mesh->numVertices;i++) vertices[i] = mesh->positions[0][i];
   rtcUnmapBuffer(scene_out, geomID, RTC_VERTEX_BUFFER);
   /* set index buffer */
   rtcSetBuffer(scene_out,geomID,RTC_INDEX_BUFFER,mesh->indices,0,sizeof(int));
   return geomID;
 }
