Re: [Factor-talk] slide-rule
Oh, sorry, I misunderstood something a while back. I thought this was a process to take a few inputs and generate a gcode file that ran some kind of machine process to produce it, but I see where you mention wanting to present a graphic simulation. Doesn't this type of input to a milling machine have its own visualizer?

I have never done any GUI programming or web programming, so either approach would represent new ground for me. I am somewhat dubious of the idea of a browser/server, as there is a lot of data to work with. I could be wrong, considering that I've never done this, but my understanding of the browser/server idea is that the program running on the browser is dealing with a very small amount of data such as the fields in a data-entry form. Perhaps it would help if I explained how my slide-rule program works: It is a three-stage process: 1.) I have words such as D-scale, A-scale, etc., that each generate a linked-list representing the scale. Each node is a MARK: list w field .kind\ the kind of mark this is (TNY, SML, MID, BIG or XTR) f field .n \ the numeric value of the mark (corresponds to .LABEL) f field .dist \ derived from N and measured in Lunits (distance from left edge) w field .orientation \ the direction of the label in relation to the mark w field .label\ the hstr of the label if there is a label constant mark \ If .ORIENTATION is N/A, then there is no label and .LABEL is irrelevant. \ The DIST value is nominally in the range [0,1], although it might extend over the edge slightly. 2.) I convert these MARK lists into SHAPE lists. These contain absolute coordinates (in inches) of all the marks and labels on a particular face of the slide-rule. Each node is a SHAPE: list p field .src p field .dst w field .siz w field .txt constant shape \ a text string or a line segment \ The P fields are .X and .Y pairs. \ If the .SIZ field is a KIND (TNY, SML, MID, BIG or XTR), then the shape is a text string. \ The .SRC field is the lower-left corner and the .DST field is not used. \ If the .SIZ field is N/A, then the shape is a line segment. \ The .SRC and .DST fields are the endpoints. 3.) I convert the SHAPE lists into gcode. All the information in each SHAPE node gets etched with G01 commands, and I also pick up the tool and move it with a G00 command from each element to the next. The Factor program would be the same as the Forth except that I will use sequences rather than linked lists, as linked lists are apparently not idiomatic in Factor. The GUI would allow the user to drag-and-drop the scales into place to construct the slide-rule, and would also allow the user to simulate the use of the slide-rule by moving the slide and the cursor to and fro on the constructed slide-rule. There would have to be an alternative #3 step above that generates some kind of graphical image rather than gcode. Does Factor have the ability to display SVG on the screen? Or would I need to generate some other kind of graphical image? If Factor has support for displaying graphical images (of any kind) on the screen, then I think the whole thing would be best written in Factor as a GUI program. If Factor can't do this, then it might be better to have the Factor program generate SVG on the server side, and then write a JavaScript program to run in a browser and display the SVG images. -- The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com___ Factor-talk mailing list Factor-talk@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/factor-talk
Re: [Factor-talk] slide-rule
I am just getting started in Factor, and am partially drawn to the ability to do cross platform GUI development, but I thought I should mention a cool ability to ship a self-contained HTTP server using their easy to use furnace library. It could launch a browser to itself on startup and produce the output format file locally. If you already do web programming it shouldn't be much of a learning curve.

[Factor-talk] slide-rule
I completed my Forth program for generating gcode for etching aluminum slide-rules. I can email it to anybody who wants it, and it is also available on www.forth.org. It is pretty robust code and anybody with a little knowledge of Forth can upgrade it to include custom scales. There are a lot of applications-specific scales that people might want, but I only have the more generally useful scales. Even if a person knows nothing of Forth, he can do some cut-and-paste to rearrange the scales into whatever layout he wants. At this time I have these slide-rules written: two-sided basic model two-sided electrical-engineer model (has hyperbolic trig functions) one-side pocket model round key-fob model (has LL scale tied to A scale for calculating compound interest) I am telling you Factor folks about this as most of you know some Forth. Also, the most likely next step with this program will be to port it over to Factor and give it a GUI so that people can construct slide-rules of their own design and also simulate them on the computer. I've never written a GUI program before, so this will be a pretty big step for me. Generating the gcode for milling machines was the most important part, as that is necessary for building physical slide-rules, but that part is done now. These are the scales that I have at this time: L-scale Common (base-10) logarithms. D-scale The fundamental [1,10] scale. DI-scale The D-scale inverted. DF-scale The D-scale folded at pi. DIF-scale The D-scale folded at pi and inverted. R1-scale The lower square-root scale. R2-scale The upper square-root scale. K1-scale The lower cube-root scale. K2-scale The middle cube-root scale. K3-scale The upper cube-root scale. A-scale The complete square-root scale. K-scale The complete cube-root scale. S-scale The sine scale in the range [5.7,90]. CS-scale The cosine scale in the range [0.0,84.3]. T-scale The tangent scale in the range [5.7,45]. T2-scale The tangent scale in the range [45,84.3]. AT-scale The tangent scale in the range [5.7,90] and tied to the A-scale. ST-scale The sine/tangent scale in the range [0.57,5.7]. SH1-scale The hyperbolic sine in the range [0.1,0.88] SH2-scale The hyperbolic sine in the range [0.88,3.0] TH-scale The hyperbolic tangent in the range [0.1,3.0] CH-scale The hyperbolic cosine in the range [0.0,3.0] LL3-scale The log-log scale in the range [2.718,22026]. LL2-scale The log-log scale in the range [1.105,2.718]. LL1-scale The log-log scale in the range [1.010,1.105]. LL0-scale The log-log scale in the range [1.001,1.010]. LL-scale The log-log scale in the range [1.010,2.718] and tied to the A-scale. LL0N-scale The log-log scale in the range [0.990,0.999]. LL1N-scale The log-log scale in the range [0.905,0.990]. LL2N-scale The log-log scale in the range [0.368,0.905]. LL3N-scale The log-log scale in the range [4.540e-5,0.368]. C-scale A synonym for D-SCALE. CI-scale A synonym for DI-SCALE. CF-scale A synonym for DF-SCALE. CIF-scale A synonym for DIF-SCALE.
