Knowledge of 3D rendering for the drawing. Ability to create accurate and detailed 2D drawings based on the provided image. Experience working with acrylic material for CNC cuts. Proficiency in using v carve or aspire software. To plot this data in Matlab, you must interpolate the data on a uniform grid, as shown below. Requirements: - Expertise in converting JPEG images to 2D drawings for CNC cut. In the following example, notice that the Gaussian profile is not sampled uniformly in the Y direction. This is an important detail when plotting data obtained from a non-uniform mesh.

This is not true of the image command in the Lumerical script environment. The standard image command in MATLAB assumes that matrix data is uniformly sampled, even when you provide the x,y position vectors. % transpose matrix, plot data, add color barĢD image plot with non-uniform, rectilinear data MATLAB commands to generate equivalent plot To get the same figure orientation in MATLAB as in your Lumerical plots, you must apply an unconjugated transpose operation and adjust the axes, as shown below.ĢD image plot with uniform, rectilinear data MATLAB uses a different convention for plotting 2D matrix data than Lumerical. While ( size(X)(2) ~= size(C)(2) ) % While dimensions of x different for X and C, Note X = Y.This page shows how to create 2D image plots of data from Lumerical's software using MATLAB. While ( size(X)(1) ~= size(C)(1) ) % While dimensions of x different for X and C, Note X = Y. This can be accomplished by adjusting the meshgrid. % Dimensions X and Y must be the same as C. % Setting X,Y dimensions, where X and Y has the same dimensions. % Converting image format and getting colormap

Subplot ( 1, 2, 2), imshow ( rgb_filter ), title('filtered') Subplot ( 1, 2, 1), imshow ( rgb_image ), title('unfiltered') Rgb_filter = imfilter(rgb_image, f, 'symmetric' ) Prompt = 'Enter path to image to be processed: ' Pkg load image % Note that this needs to be commented out in MATLAB Insert path to image you want to analyse.

Run the script via run 'script_2Dimage_to_3D.m' Save the script as 'script_2Dimage_to_3D.m' % This script transforms a 2D RGB image to a 3D image, where the Z axis is given by the RGB number. Since this hasn’t any real purpose, other than some fun scripting, I will leave it here (for now). The representation is however in black and white. Is it possible to export the result to a Wavefront object file? Yes, primarily due to the important checking that the axes are of similar dimensions/values. The big downside of the script, as well as with MATLAB/Octave in general, is the exportation to a suitable format.
