[Affinity Photo] Procedural Texture beginner formula info


Recommended Posts

Hi Everyone,

I have been on a mission to fill the void in the Macro environment by the lack of gradient support.  To this end I was introduced to Procedural Texture and saw some possibilities and started tinkering.  The manifestation of this can be found in several working groupings of R,G,B Vignettes and Linear gradient macros uploaded in the Resource section that I will update as interesting developments occur.

In this, I will attempt to break down some of the math and show you how I am attempting to work around my limited knowledge of geometry(has been a while since trig) to make this accessible to the beginner who wants to implement some control over the basic examples and give some direction over how to navigate this powerful tool.  If you would like some immediate video immersion of outstanding examples, that I may start from or point to, see Graphicxtras.com on youtube.

If anyone has anything to add/correct/questions, comments, etc. please jump in...this is only meant as a supplement to the Affinity Photo Procedural Texture help section that can leave the beginner a little overwhelmed.

So, here is the first installment of my experiences.  And certainly, if anyone wants to use these explanations in video format please feel free...just post a link for everyone to see it.

Procedural Texture 101

      https://en.wikipedia.org/wiki/Procedural_texture

These are some common definitions of elements of an equation

w = width of document
h = height of document
x = horizontal axis
y = vertical axis

rx = relative x(position) to upper left hand corner expressed as (0,0) horizontal axis (rx,0)
ry = relative y(position) to upper left hand corner expressed as (0,0) vertical axis (0,ry)

R = red channel
G = green channel
B = blue channel
A = alpha channel

Relative x and y  (rx,ry)

x and y coordinates can also be specified as values relative to any starting point on the screen or any subset of the screen such as an image. On the Web, each clickable area of an image map is specified as a pair of x and y coordinates relative to the upper left-hand corner of the image.

      https://en.wikipedia.org/wiki/Cartesian_coordinate_system 

osc(input, parameter)

The following syntax follows the typical convention of function(input, parameter) where the function( = osc )

      https://en.wikipedia.org/wiki/Wave_function  

      https://en.wikipedia.org/wiki/Wave_equation 

      https://en.wikipedia.org/wiki/Oscillation_(mathematics)

osci(input, parameter)

This function example represents the oscillation over the set (in this case an interval) of the function( = osci )

      https://en.wikipedia.org/wiki/Interval_(mathematics)

 

This example is formula from the Checkered preset

osci(rx*c/w,ry*c/w)    variable   c(Z)   produces squares

+ addition of variable a(Z) to control vertical axis

osci(rx*c/w,ry*a/w)    c(Z)  produces horizontal rows  a(Z) produces vertical rows

example.  c=0 (no horizontal rows)
                  c=1 (1 horizontal row)
                  c=25 (25 horizontal rows)
                  c=5, a=5  (square with the size of 5 rows horiz and 5 rows vert)(effectively enlarging 5x larger than (1x1)
                  c=5, a=1  (rectangle with the size of 5 rows horiz and 1 row vert)
                  etc.

See video example of procedural texture squares at Graphicxtras.com

 
I will update with macros of these examples as I go along, or if you want to get started go to procedural texture and find the checkered preset and start experimenting.

Please note that I can apply a radial gradient from a macro under these conditions.  With a radial gradient loaded into swatches, apply gradient using rectangle tool.  The unfortunate part is that the center of the radial gradient is relative to the (0,0) coordinates effectively quartering the gradient.  Linear gradient works fine.  If I am recalling correctly, the linear gradient only loaded a single color and not the gradient in previous versions.  - T V

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.)

Thanks, @T V. This has gone some way to improve my understanding of procedural functions. I might even have another go at using them. Keep up the good work, but I may come back to you for further clarification.

However, I think that this thread really belongs in the Tutorials forum.   I would suggest that a moderator move it.

Helpful. Thanks. I've yet to get properly into oscillators, etc. Mostly doing RGB algebra of late.

It would be great if there was more definitive help available on the PT functions.

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

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!

OK, so I install and apply your macro to an image, and I get four black or white rectangles. What equations did you use to create these? How can I modify it to suit my needs. I need to grasp the relationship between these identifiers in the formulae to actual parameters that I can insert into an equation.

Say I wanted to create a Perlin Noise pattern that I wish to blend into an image. What formulae do I enter into the boxes in the Procedural Texture filter? Once I can see a couple of worked examples, I should be better placed to create filters myself.

Hi John, 

Please double click on the procedural texture layer and the procedural texture dialog box will appear with the formula in the R, G, B locations at the top.  The controllers are at the bottom of panel.  When you make any adjustments of the formula the box at the top with the procedural texture name will disappear.  At this point you will know that you can save the new formula as a preset.  Also, when making adjustments of the controls from the default setting you will be able to save as a control presets just above the controls.  When you save these settings you will be able to see the control settings to know how you ended up where you are. 

Please see the wikipedia  perlin link for more info.  These formulas seem to use the x,y coordinates as a square grid cell to warp in a predictable way.  That is how the knowing the math function and what they do help you make the effects that you want.  See Graphicxtra for some outside of the box creativity...

These examples are not perfect.  It is a mystery to me when I merge the colorful representation to a pixel layer or overlay it seems to mute the colors to a 50% greyed out(hue).  Applying a blend mode at 100% softlight looks as if it was really 50% opacity(softlight nullifies the 50% grey visibility).  I have verified that other formulas are not acting as this.  Perhaps this is a problem using the perlin function as perlin alone. Perlinsc does not change this problem. 

I will look for other perlins as examples...  - T V

@T V I'm out of likes and thanks to spend on this forum, so like this: great hints, thanks! 😀

Thanks from me as well. I think that I may actually be able to create one of these textures myself before too long!
