C++ (Cpp) isPointVisible Examples

Example #1

bool Frustum::isBoxVisible(Vector3D min, Vector3D max)
{
   if(isPointVisible(min.x, min.y, min.z))
      return true;

   if(isPointVisible(max.x, min.y, min.z))
      return true;

   if(isPointVisible(min.x, max.y, min.z))
      return true;

   if(isPointVisible(max.x, max.y, min.z))
      return true;

   if(isPointVisible(min.x, min.y, max.z))
      return true;

   if(isPointVisible(max.x, min.y, max.z))
      return true;

   if(isPointVisible(min.x, max.y, max.z))
      return true;
