1. ## [Affinity Photo] Procedural Texture beginner formula info

Can someone verify if they can find noise input presets in the bottom preset area above the controllers? If so, there are a few my examples for your pleasure...if not I will post some images...

noise perlin(rx*c1, ry*d1, a, b)*red perlin(rx*c2, ry*d2, a, b)*green perlin(rx*c3, ry*d3, a, b)*blue controlers red, green, blue (0,1) controls base colors a (R) octives ( waves ) b (0,1) persistence ( contrast ) c1,c2,c3 (R) horizontal shift d1,d2,d3 (R) vertical shift - notes on formula https://en.wikipedia.org/wiki/Perlin_noise perlin function controls 4 factors/parameters (position rx, position ry, parameter a, parameter b) separated by commas rx*c1 relative x multiplied by horizontal shift variable (small increments better) ry*d1 relative y multiplied by vertical shift variable (small increments better) a = octives seems to affect hardness in relation to b persistence b = persistence seems to act as contrast and blur in relation to a when a > 1 *red multiply by a number between 0 and 1 can also be thought of as 0-255 T V - NOISE PT R,G,B V1.0.afmacros ENJOY AND EXPERIMENT - T V Apologies, as lost track of where I got this example. I may have simplified it from a preset as it indicates octives and persistence. It is an easy introduction into something different and in it's black form I had no perceived use until now in r,g,b. Please note this can be expanded upon introducing a scale factor to grow, variables for r,g,b separations, etc.. By complete coincidence, go to Graphicxtra.com on youtube and see today's Affinity Photo video. It will help you finish this off to new levels of creativity!

While this may be better explained by a math professor or an Affinity developer, I will try to do my best to dissect these into digestible bite sized portions. Soon I plan on posting some basics on rx,ry math. May be easier to understand in a video(not my thing...yet...) due to having a visual reference. I will include simple macros of movement examples. I think that seeing it and being able to play with it at the same time helps reinforce the connection. Right now I am about 8 macros ahead of myself of R,G,B variations of the standard presets. It has increased my appreciation for these formulas beyond belief. They are all usable by the beginner to create multi colored gradients or use as a starting point and just have exponential fun. Looking forward to your and everyone's contribution to this. - T V

Sounds good, not sure how to do that yet...this started off as a call for help rather than a tutorial. I am just using this as my online reference with examples that got organized maybe enough for others to follow along. Things are moving so fast that I am needing much organizing as I closed AP last night with a great PT using the squares still open not saved and in starting over turned out different. Not quite as nice. One day maybe we will all get a little more confidence working with it. Glad your enjoying it!

smoothosc smoothosc(rx*a1/w,ry*b1/h,c1) smoothosc(rx*a2/w,ry*b2/h,c2) smoothosc(rx*a3/w,ry*b3/h,c3) controllers a1,a2,a3(R) r,g,b horizontal shift creates divisions of document width (w) b1,b2,b3(R) r,g,b vertical shift creates divisions of document height (h) c1,c2,c3(0,1) r,g,b hard edge shift creates gradation - notes on controllers (R) Real numbers whole and decimal. Both positive and negative numbers work. The preset formula was originally set up for (Z)*. *While searching for hot keys to control the numbers while scrolling over them I found two. 1) while hovering over (R) number box with mouse, scroll mouse wheel to change the numbers. 2) holding down shift key will shift the whole numbers by increments of 10. 3) holding down control key will shift the decimal by .1. This is incredibly helpful for fractional increments. (I can verify this only for Windows). (0,1) All number between and including 0 to 1. Represented as a slider. - notes on formula This function is a variation of osc and has 3 factors/parameters ( rx, ry, c1 ) separated by commas. rx (relative x) multiplied by a1 (number of horizontal divisions) divided by w (document width) ry (relative y) multiplied by b1 (number of vertical divisions) divided by h (document height) (many times, this will also be divided by document width (w)) c1 this is the smooth portion of the osc formula that creates the gradient (Note that gradient spread shifts equally (+, -) from division edge.)

6. ## [Affinity Photo] T V - LINEAR PT R,G,B V2.0

Hello All, I have been inspired by a thread I started this morning on Basic Procedural Texture Deconstruction to allow beginners to see into the process and the math to be able to create their own Procedural Texture. I thought sharing some of my documentation would be a good place to start and fortunately videos are available at Graphicxtra.com. They are a great resource. Unfortunately, not how I got started, but, I am so happy to have found them that I will start seeing if I can work through an entire video at some point. For now, I am still figuring out that gradient macro workaround and this is a linear variation that introduces another formula in a unique way. I hope you like it as I hope to expand on this one a little. LINEAR V2.0 Formula: smoothosc((c1*rx-d1*ry)*a1/w,b1) smoothosc((c2*rx-d2*ry)*a2/w,b2) smoothosc((c3*rx-d3*ry)*a3/w,b3) Inputs: a1(R),a2(R),a3(R) lines b1(0,1),b2(0,1),b3(0,1) hard edge c1(-1,1),c2(-1,1),c3(-1,1) horiz shift left, right from center d1(-1,1),d2(-1,1),d3(-1,1) vert shift up, down from center For now, this produces linear gradients that shift left or right, up or down, rotate limited( this happens when using the horiz shift and the vertical shift at the same time). The R,G,B creates multi colored gradients. This layer is non destructible and applies at 50 percent grey coverage at 100 percent opacity for choosing color gradient. Set blend mode to overlay or soft light to see image and adjust transparency to taste. T V - LINEAR PT R,G,B V2.0.afmacros Enjoy and Experiment - T V NOTE - I started a new beginners supplement to the Procedural Texture Help section in the tutorial resource section. You will be able to find more examples with free Macros and my attempts to break them down in understandable ways. It should help others become a little more comfortable with this incredible process. Future examples will show up on the tutorial forum page...

Thanks, it's a nice one!😁
13. ## macros Affinity Photo Dave's Multiple Color Model Video Macro

Here is my experience with Dave's Multiple Color Models. This macro follows Dave's video, give or take a blend mode and choice of channel. To run this macro you will need to have Dave's Colour Models V2.afmacros installed in the macro library. T V - DAVE'S MULTIPLE COLOR MODEL.afmacros . Enjoy - T V
