IFS Edit tutorial ----------------- Hello, and welcome to the brand new IFS Edit tutorial for dummies. Here we will create, literally key by key, a very simple IFS fractal known as a "tree". First, start IFS Edit. If it doesn't present you with a black screen with some gray windows and a triangular fractal, complain to Seven that his programs don't work. In the other case, we'll remove the existing fractal: press SHIFT-F11. This puts us back at the most simple fractal with 2 identical transforms. If anything goes wrong, press SHIFT-F11 and start over. The current selected operation is SCALE-X (notice the blue X in the lower left corner, in the SCALE row and X column). You can use the arrow keys to move to other operations, but don't do that yet. We will start by making the trunk of the tree. Press numeric - (minus) 30 times, you'll notice one box grows thinner. At the same time the topmost number in the first sideview should drop form 50 to 20. Next, go to SCALE-Z by pressing the right arrow twice, and press minus 30 times again. (Henceforward, I'll assume you can interpret operations like "add 20 TRANS-Y" yourself. If not, ask a nearby family member for help). Add 20 Trans-Y, so you move the thin box below the cube. The 4the number in the middle view should read 100. Press Tab once to select the cube. Sub 10 Trans-Y to rise it. Now we're going to create one branch (out of a total of 2): Press SHIFT-F4 to clone the topmost cube. You won't see anything change, because the new cube is drawn over the old. Look at the lower left windown, the "NR of IFS transforms" should read 3 now. The new cube is automaticlly selected when you made it. Sub 20 TRANS-X it, then sub 10 TRANS-Y it. The vector coordinates (the lowest number) in the sideviews should now read (-100, -100, 0). Sub 20 ROTATE-Z it, so the branch starts to curl. The rotation numbers (2nd nr) of the X and Y sideview should read 28.13. Now press TAB twice, so we're back to our old topmost cube. We'll use it to make the second branch, symmetrical to the first: Add 20 TRANS-X, then sub 10 TRANS-Y, then add 20 ROTATE-Z it. And voila, here we have a clearly tree-like fractal. Applause! However, the different parts are not connected yet. Press TAB twice, so you select the trunk. Add SCALE-Y it until the branches of the trunk touches the trunks of the 2 branches (should be about 10 keypresses). Maybe you notice this fractal is actually 2-dimensional (by pressing CTRL + Keypad 4 or 6 f.e. CTRL-SPACE stops the motion). Exercise fo the reader: clone a branch, and move the 3 branches symmetrically around the trunk to get a 3D tree. If you can't get anywhere, type "TESTTREE" and press SHIFT-L, this should load the resulting fractal so you cansee what it should look like.
