Every row of @var{tri} represents one triangle ## and contains three indices into [@var{x}, @var{y}] which are the ## vertices of the triangles in the x-y plane. @var{z} determines the ## height above the plane of each vertex. ## ## The color of the trimesh is computed by linearly scaling the @var{z} values ## to fit the range of the current colormap. Use @code{caxis} and/or ## change the colormap to control the appearance. ## ## Optionally, the color of the mesh can be specified independently of @var{z} ## by supplying a color matrix, @var{c}. If @var{z} has N elements, then ## @var{c} should be an Nx1 vector for colormap data or an Nx3 matrix for ## RGB data. ## ## Any property/value pairs are passed directly to the underlying patch object. ## ## The optional return value @var{h} is a graphics handle to the created patch ## object. ## @seealso{surf, triplot, trimesh, delaunay, patch, shading} ## @end deftypefn function h = trisurf (tri, x, y, z, varargin) if (nargin < 4) print_usage (); endif if (nargin > 4 && isnumeric (varargin{1})) c = varargin{1}; varargin(1) = []; if (isvector (c)) if (numel (c) != numel (z)) error ("trisurf: C must have 'numel (Z)' elements"); endif c = c(:); elseif (rows (c) != numel (z) || columns (c) != 3) error ("trisurf: TrueColor C matrix must be 'numel (Z)' rows by 3 columns"); endif else c = z(:); endif ## FIXME: Is all this extra input parsing necessary? ## Is it for Matlab compatibility? if (! any (strcmpi (varargin, "FaceColor"))) nfc = numel (varargin) + 1; varargin(nfc+(0:1)) = {"FaceColor", "flat"}; else nfc = find (any (strcmpi (varargin, "FaceColor")), 1); endif if (! any (strcmpi (varargin, "EdgeColor")) && strcmpi (varargin{nfc+1}, "interp")) varargin(end+(1:2)) = {"EdgeColor", "none"}; endif hax = newplot (); htmp = patch ("Faces", tri, "Vertices", [x(:), y(:), z(:)], "FaceVertexCData", c, varargin{:}); if (! ishold ()) set (hax, "view", [-37.5, 30], "box", "off", "xgrid", "on", "ygrid", "on", "zgrid", "on"); endif if (nargout > 0) h = htmp; endif endfunction %!demo %! clf; %! colormap ('default'); %!
