I have done many FFTs of optical images and systems in Mathcad 15. I convert them to Prime 8 and almost all of them will not display the 3d plots due to the error "3D plots must be less than 40,000 points". Why? They worked fine in 15.
Also, you can no longer get a good smooth 2D image displayed as if you captured on a ccd camera. Prime 8 doesn't allow me to generate theoretical images that I can compare to my experimental ones captured with the ccd. Why was this capability lost? Or is there a way to do it with 8?
Hi,
Yes Prime 8 can generate theoretical images as in Mathcad 15.
Construct a red, green, and blue channel and augment them into one larger matrix.
Save this image to a BMP file is simplest.
Then use Document | Regions | Image to insert the image into the document.
You could also change the rgb to hsv and save as a JPG etc.
Look at all the options under Functions | Functions | Image Processing
Do not know how to deal with the 3D plot limitation other then to export matrices to be plotted and use the free Scilab program at https://www.scilab.org/

Each plot has 40000-1 points.
