#PLOTTING TRANSPARENT RECTANGLE MATLAB UPDATE#

Setting a figure window’s transparency requires using Java Run-time Engine (JRE) 1.6.0_10 (also called “Java 6 update 10”) or higher. You may also wish to use Malcolm Lidierth’s MUtilities, which also has similar functionalities (plus some other goodies).

I’ve prepared a Matlab utility that contains all these options, including optional blocking/non-blocking fade effects, in my setFigTransparency utility, which is available for download on the Matlab File Exchange. If you fade-out completely (i.e., to a value of 0.0), it might be a good idea to actually close the figure window once it gets the totally-transparent value of 0.0. Of course, you can also fade-in/out to intermediate values such as 0.3 or 0.8. % If blocking, do the fade effect immediatelyĬom.(jWindow,newAlpha) Ĭom.(jFrame,newAlpha) Steps = fix(abs(deltaAlpha) / maxStepAlpha) + 1 NewAlpha = currentAlpha + stepAlpha*stepIdx Ĭom. % If blocking, do the fade effect immediately if blockingFlag || steps= 1 for stepIdx = 1 : stepsĬom. StepDuration = fadeDuration / (steps- 1 ) Steps = fix ( abs (deltaAlpha ) / maxStepAlpha ) + 1 % Compute the required opacity-setting steps

They can be set to any floating-point value between 0.0-1.0, where an opacity of 0.0 means full transparency, and any value in between means partial transparency (i.e., translucency): Actually, setWindowOpacity sets the opacity level, rather than transparency, but they are obviously complementary and I personally find “transparency” to be more easily understandable.īy default, windows are created with an opacity of 1.0 (= not transparent). Then use Java’s setWindowOpacity method to set the window’s transparency value. Matlab figure window transparencyįollowing an idea I got from Malcolm Lidierth’s MUtilities submission on the Matlab File Exchange, the solution for setting Matlab figure window transparency is quite simple: Get the figure’s underlying Java window reference handle, as in last week’s article. The short answer is that there is no supported way of doing this with pure documented Matlab, but it is trivially easy to achieve using just a bit of Java magic powder (surprise, surprise). This could be used, for example, for window fade-in/fade-out effects. Every now and then, a user asks whether it is possible to make an entire Matlab window transparent ( example). % Replace default input arguments by input values

% Default alpha value for the cube's faces % Default coordinates of the origin point of the cube % * COLOR : 3-elements vector that defines the faces color of the cube

% * ALPHA : scalar that defines the transparency of the cube faces (from 0 % * ORIGIN: 3-elements vector that defines the start point of the cube

% * EDGES : 3-elements vector that defines the length of cube edges % PLOTCUBE(EDGES,ORIGIN,ALPHA,COLOR) displays a 3D-cube in the current axes % PLOTCUBE - Display a 3D-cube in the current axes

Here is the 'plotcube' code in case the link to the original code by Oliver breaks someday: function plotcube(varargin) This would require changing the code somehow to update all the XYZ data. I believe this is from calling the 'patch' function multiple times.Ī better solution would be to vectorise to put all your points (vertices/faces/whatever) together in a single matrix first and then call the function only once (no 'for' loop). running this 'plotcube' function in a 'for' loop in MATLAB over thousands of blocks. for large models (many cubes) this is very slow to run.Į.g.

(above) change the section in Olivers code, adding in the four extra lines of code as follows: (replace the whole cellfun section with this including the new 'EdgeAlpha' and 'EdgeColor' lines): % Set this value to whatever you want even a variable / matrixįor more info on 'patch' please see patch documentation. fixed edge colour, or a colour that changes with Z-value etc.)
