In fact, this would be done in EMT in the following way. That is something EMT can only do with Povray currently. It shows that the 3D rendering of Scilab can display scenes with intersecting objects of different type. Plot the Add 2d graphics on 3d graphic'Ĭurrent_axe.background = BackgroundColorId my_plot_desc = 'plot3d and use of geom3d' Here is a more complicated example, which I found in the net. We already say the genfac3d() command above. Scilab allows plots which are very close to the underlying rendering. The >user statement lets the user turn the plot with the cursor keys. I tried to mimic the default colors of Scilab. For true 3D scenes, Povray can be used from EMT. But this is sufficient for many nice plots. Therefore the type of scenes it can display is somewhat limited. The display seems to be based on OpenGL or some other 3D rendering. The plot can be turned by the user with the mouse. In fact, being able to magnify without pixelation is a much overrated feature.įor an example of a 3D plot, I found the following code. Fonts, point sizes and line widths have to changed too. However, it should be clear that magnification is not the proper answer to scaling. This gives a smoother way to magnify the plot. SVG and PS can be saved by Scilab and EMT too. This can be switched off when saving the plot in EMT. The plot looks different due to the anti-aliasing. To get a similar look as Scilab, tan aspect ratio of 4:3 is set, and a special value for the grid style. The elementary plot() can be used, but it will not display any grid or coordinates. You can do the same simple vector plot in EMT. If a function is used instead of a vector y this is no longer necessary. Too much zoom will therefore show the line segments. Of course, this does not mean that the function is known. So it can be zoomed with new coordinates in the graphics window. The display program puts the axis to the plot. The plot is a bit naked in this simple form. It uses vectors x and y to plot the data. The default way is the most elementary way that has been introduced with Matlab and its vector language.
