I'd like it to be able to read fractint l-systems. I have some questions -- user-type questions, that should maybe be kept in the manual, things I will answer myself through experimentation: - - Do both direction pointers start pointing to the right? - - If I understand correctly, \ and / move a direction pointer that controls the direction of D and M -- right? And D and M use the same current-point that F and G do, right? - - All the numbers are delimited by having non-numeric material follow, right? - - Which way does | turn if the angle is odd? Left or right? - - "Increase" and "Decrease" angle mean "turn left" and "turn right", right? - - What exactly do [ and ] save and restore? I know they save the current +-FG state, the current position, and the current @ scale; do they also save the current \/DM state, the current ! state, and the current color? These can be determined by experimentation. These others would be more difficult: - - Does the grammar require that the { fall on the same line as the lsystem name? - - Is everything case-insensitive? - - Are the ", sequences in FlowSnake accidental, or do they have meaning I do not comprehend? - - Is it legal to include the Penrose tiles? Penrose recently sued a toilet-paper company for printing the Penrose tiles on their toilet paper.

I wrote these modifications because I thought the basic concept Oliver came up with was very interesting but the resulting images didn't tell me enough about the dynamics of the iteration and I wanted to get some idea of the relative contribution that each of the functions was making to the initial and final value of z. This is just my first cut at extending Oliver's idea and I'm sure that somebody (like Sylvie) can improve upon it. Anyhow, this is what I've done in these two formulas: The fn1 function is represented by the color red. The fn2 function is represented by the color green. The fn3 function is represented by the color blue. I'll call the contributions that these functions make c1, c2 and c3. If c1 is the largest of the three: The color of the pixel will be in the range of magenta to yellow, with red in the center. If c2 > c3 the color will be shifted towards yellow; if c3 > c2 the color will be shifted towards magenta. If c2 is the largest of the three: The color of the pixel will be in the range of yellow to cyan, with green in the center. If c1 > c3 the color will be shifted towards yellow; if c3 > c1 the color will be shifted towards cyan. If c3 is the largest of the three: The color of the pixel will be in the range of cyan to magenta, with blue in the center. If c2 > c1 the color will be shifted towards cyan; if c1 > c2 the color will be shifted towards magenta. Although the images won't tell you anything exact about any particular pixel, you can learn quite a bit how things change from pixel to pixel. Suppose, for example, that a pixel is red-orange. This tells you that c1 is largest, c2 the next largest and c3 the smallest. If the pixel adjacent to this pixel is orange-yellow, it tells you that c2 has increased from the first pixel to the second. The Mutant_Start formula shows the relative contributions at the begining of the iteration. The coloring of the images that use this formula tend to be somewhat predictable. The Mutant_End formula shows the relative contributions at bailout which tend to be much more interesting. All of the pars use Oliver's original parameters and functions, except for Mut_end_02_zoom. The image created by this par shows that the patterns created by the areas of influence of the three functions exhibit a high degree of self-similarity. This is also the best-looking image from an artistic standpoint. In all the pars except this one I've reduced maxiter from 1500 to 500 for speed. Anyhow, this is a great idea you had, Oliver, and one that deserves to be expanded upon much more than I've done so far.

Well, if God is a perfect fractal, perhaps they were fractal dice. Such dice would have an infinite number of sides, though not each side would have to be the same size. This would make certain rolls more likely, though the chance of any particular roll occurring would always be 1 to infinity! > Chris corresponded: >(what were they _made_ of, since there was no firmament?

You can slice (decompile) a lot of design programs to get a DXF parser, the output, of course, will vary by program... However, it can be ported a *lot* of different ways from there.

Image one looks like it was done with my Bubbles rendering method. Image two looks like it was done with my 3D Stalks rendering method. Both of these methods (and many more) I've implemented with Fractint formulas. >Also the pseudocode looks strange to me. Me too.

It's certainly different. And it would be considerably faster as a builtin method. And you wouldn't have to worry about "stealing" the method from that web page - I developed the method in 1993. I think that he probably got the methods from one of my web sites where I describe them briefly.
