Didn't get very far, looks like my addons are missing some stuff, which might be my fault. Didn't think I would get much further with the graphics labs. My notes:
Lab errors (From jx 19, which jx 18 suggested should be run first: -- (2 of 24) Loading the Graph utilities -------------------- To load Graph, enter: load 'graph' For this lab, we will also use the numeric and trig utilities: ) load 'graph' not found: /j/addons/graphics/graph/graph.ijs |file name error: script | 0!:0 y[4!:55<'y' ---------- Lab: Fractals, Visualization & J To advance the lab, press ↵ -- Chapter 1 Introduction ----------------------------------- -- ((1) 1 of 21) Introduction ------------------------------- This lab is designed to provide a hands-on introduction to the visualization of mathematical objects, algorithms and data. This includes the plotting of functions in two and three dimensions, the creation of fractals using a wide variety of methods and the manipulation of data and images in general. The lab is based on the first 2 chapters of "Fractals, Visualization & J" by Cliff Reiter. The lab makes essential use of the standard graph utilities. If necessary, first take the lab "Graph Utilities". ) -- ((1) 2 of 21) Introduction (ctd) ------------------------- We require the graph, viewmat, numeric and trig libraries, which can be loaded as follows: ) load 'graph viewmat numeric trig' not found: /j/addons/graphics/graph/graph.ijs |file name error: script | 0!:0 y[4!:55<'y' --------------???????????? jd '~/addons/graphics' afm bmp color plot -------------??????????? From jx 18: -- ((1) 7 of 21) Experiment: Plotting Polygons (ctd) -------- Draw the polygon. The commands used open a graph window, draw the polygon, then show the window. Note that the right argument to gdpolyon should be a list of points. A matrix would be treated as a separate polygon drawing for each row. Now try drawing a blue hexagon (6 sides) before continuing the lab. ) gdopen '' |value error: gdopen | gdopen'' |[-0] > On Feb 13, 2014, at 9:19 PM, Jim Russell <[email protected]> wrote: > > Great!
