Since only a couple interations are done, they are not really fractal. I found the idea in "Spectrum der Wissenschaft", the german release of "Scientific American". The interations are done on strings. The strings consist of eight different characters : - '0' : draw a line straight forward. - '1' : like '0', but draws a leave at the end of the line. - '2' : like '1', but with a red flower. - '3' : like '1', but with a yellow flower. - '\' : turn left and begin a new branch. - '/' : turn right and begin a new branch. - '[' : turn left or right and begin a new branch. - ']' : finishes the actual branch and continues drawing where the branch began. At each interation '0', '1', '2' and '3' are replaced by a defined string. For example : '0' -> '1[0]1[0]0' '1' -> '12' '2' -> '2' '3' -> '3' If the initializer was '01' the first generations will be : '0 1' | | V V '1[0]1[0]012' The secons generation will be : '1 [0 ]1 [0 ]0 1 2' | | | | | | | V V V V V V V '12[1[0]1[0]0]12[1[0]1[0]0]1[0]1[0]0122' and so on... As you can see, after a few generations the strings becomes quite large ! If the specified number of generations are done, the tree will be drawn. The best way of understanding this procedure is simply trying it. LEARNING BY DOING !! --------------------------------------------------------------------------- INSTRUCTIONS ŻŻŻŻŻŻŻŻŻŻŻŻ When you start TreeGrow a window will be opened and the library will be loaded. There are several gadgets visible in the window : 'Init' : Here you enter the initializer. '0 ->' : The string which replaces a '0' in each interation. '1 ->' : The string which replaces a '1' in each interation. '2 ->' : The string which replaces a '2' in each interation. '3 ->' : The string which replaces a '3' in each interation. 'Size' : The length in pixel of the first line. 'Rate' : The percentage how long will be the next drawn line. If you enter '100' every line will be as long as in 'Size' specified. With '50' every line will be halve as long (50%) as the previous line. 'Angle' : The range of the angle which is used, when an '\', '/' or '[' occures. The actual angle is a random value in this range. The values are entered in degree. '30 to 40' turns a rondom angle between 30 and 40 degrees to the left or right. 'Generations' : The number of generations which are created, before the tree is drawn. 'Start' : Start the generation and drawing of the tree. A highres-interlace screen will be opened and the tree will be drawn. Press the right mousebutton to interrupt the drawing. If the drawing is completed press the left mousebutton to return to the main window. 'Save' : If there is already a drawn tree, you can save it using this gadget. The file is a standart IFF file. 'Name' : If you want to add the actual tree to the library, you have to enter it's name in this gadget. 'Save' : Save the library to the current directory. When you exit TreeGrow the library won't be saved !! 'Add' : Add the actual tree to the library. the containings of all gadgets are saved. 'Del' : Remove the highlighted tree in the list below these gadgets from the library. BE CAREFUL !! Select the name using the two arrows. 'Use' : Load the parameters of the highlighted tree in the list into the gadgets. --------------------------------------------------------------------------- INSTALL LIBS ŻŻŻŻŻŻŻŻŻŻŻŻ TreeGrow needs some libraries to run. These are - ilbm.library - req.library - mathieeesingbas.library - mathieeesingtrans.library If they are not already in the current LIBS: directory TreeGrow won't start. Start InstallLibs to copy them to the LIBS: directory. --------------------------------------------------------------------------- Pink says : "Goodbye.." 21-Dec-1992 Hamburg
