Affine3d makeCameraPose (const Vec3d &position, const Vec3d &focal_point, const Vec3d &y_dir)
 Constructs camera pose from position, focal_point and up_vector (see gluLookAt() for more infromation). More...
 
Affine3d makeTransformToGlobal (const Vec3d &axis_x, const Vec3d &axis_y, const Vec3d &axis_z, const Vec3d &origin=Vec3d::all(0))
 Takes coordinate frame data and builds transform to global coordinate frame. More...
 
Mat readCloud (const String &file, OutputArray colors=noArray(), OutputArray normals=noArray())
 
Mesh readMesh (const String &file)
 Reads mesh. Only ply format is supported now and no texture load support. More...
