FNPlotter Surface

3DFNEdit Extras

FNPlotter Version 1.03, 14 May 1996 This application is a front end for MultiPlot. It allows you to enter up to four functions, y=f(x), in BASIC format, and will then produce a file in the correct format for loading into MultiPlot. If MultiPlot is active at the same time as FNPlotter, then the data file is transferred transparently, using the Desktop message transfer facilities. It is therefore possible to overlay graphs of known functions with other data produced by e.g. GraphDraw. FNPlotter is 26/32-bit neutral and should run on RISC OS 3, 4, 5 and 6, and has also been tested successfully on the BeagleBoard (ARMv7/Cortex-A8/OMAP3 port) running RISC OS 5.17. You may download the following files, which are all zip archives. The FNPlotter application (file size 22k) The manual in Impression format (file size 6k) The manual in Ovation Pro format (file size 6k)

Surface Version 1.04, 5 May 2003 This application is a very simple 3D function (surface) plotter. It takes as input a text file containing the x, y, and z data for a function of the form z=f(x,y), and draws a 3D view of the function. This version is very dumb and does not allow any choice in how the graph is displayed. Better things will emerge in the course of time, I hope. Use e.g. 3DFnEdit to produce data files of BASIC type functions in the correct format for Surface to understand. Surface is 26/32-bit neutral and should run on RISC OS 3, 4, 5 and 6, and has also been tested successfully on the BeagleBoard (ARMv7/Cortex-A8/OMAP3 port) running RISC OS 5.17. You may download the following files, which are all zip archives. The Surface application (file size 102k) The manual in Impression format (file size 6k) The manual in Ovation Pro format (file size 6k)

3DFNEdit Version 1.03, 19 May 2003 This application is a front end for either of the authors surface plotting applications, viz. Surface or 3DPlotter. It allows you to enter a function, z=f(x,y) in BASIC format, and will then produce a file in the correct format for loading into the actual surface plotting programs. If one of these programs is active at the same time as 3DFnEdit, then the data file is transferred transparently, using the Desktop message transfer facilities. The data files can also be saved in ASCII format. 3DFNEdit is 26/32-bit neutral and should run on RISC OS 3, 4, 5 and 6, and has also been tested successfully on the BeagleBoard (ARMv7/Cortex-A8/OMAP3 port) running RISC OS 5.17. You may download the following files, which are all zip archives. The 3DFNEdit application (file size 26k) The manual in Impression format (file size 6k) The manual in Ovation Pro format (file size 6k)
