function MuscleHandle = VISUALISATION_view_muscle_origins(MWHandle, MWDATA, BLDATA, MuscleId)
% Function for visualising the muscle origin parameterisation.
%--------------------------------------------------------------------------
% Syntax :
% MuscleHandle = VISUALISATION_view_muscle_origins(MWHandle, MWDATA, BLDATA, MuscleId)
%--------------------------------------------------------------------------
%
% EPFL - LA - LBO SHOULDER MODEL
% Created by : David Ingram (LA - EPFL)
%
% File Description :
% This function either creates a visualisation of the muscle origins or
% updates an already existing one.
%
% MWHandle contains the handle
% MWDATA msucle wrapping data structure
% MuscleId is the muscle identification number
% BLDATA bony landmark data structure
%--------------------------------------------------------------------------
% Initialise the output
MuscleHandle = MWHandle;
% Get the Origin Data
Origins = MWDATA{MuscleId,1}.AnchorOrigin;
Origins = cell2mat(Origins);
% Build the Spline
WayPoints = MUSCLE_TOOL_spline_build(MWDATA{MuscleId,1}.AnchorOrigin, MWDATA{MuscleId,1}.MSCInfo.InterpType, 100);
% Rotate the Points into absolute frame
Origins = MAIN_TOOL_geometry_functions(...
'Rotate Points From Local To Global Frame (Current)',...
[Origins(:,1), WayPoints, Origins(:,end)], BLDATA, MWDATA{MuscleId,1}.MSCInfo.OriginRef);
%--------------------------------------------------------------------------
% The input handle is empty (no mesh plot has been created)
%--------------------------------------------------------------------------
if isempty(MWHandle)
% Create the plot
MuscleHandle = plot3(Origins(1,:), Origins(2,:), Origins(3,:),...
'color', 'green',...
'linewidth', 2,...
'marker', 'o',...
'markerfacecolor', 'green',...
'markersize', 6);
%--------------------------------------------------------------------------
% The input handle is not empty
