The fixing and testing for the next release are now complete...if all goes according to plan, will do a release this weekend!

@villares I can tell from the picture this is going to be a lot of fun!

Tonight's #CreativeCoding revolved around playing with Cartesian and Polar coordinates.

The object on the left was drawn in the traditional Cartesian coordinates. Then the values in the graphics array were deliberately misinterpreted as being written in Polar coordinates. So the value for x became the radius, and the value for y theta

Then r and theta were converted back to Cartesian so they could be displayed by #Py5 resulting in the shape on the right

Code: https://codeberg.org/TomLarrow/creative-coding-experiments/src/branch/main/x_0086

A series of triangles on the left, mostly red, tan, and some blue, that for some reason looks like a low poly lobster, gets bent into a curved version of the shape on the right
A very complex shape of many triangles in blue green and tan on the left become almost a flower looking shape on the right
A long red green, tan and white snake of triangles on the left, becomes a big swirl of arcing shapes of the same color on the right

@TomLarrow these are great!

Did you know that Py5Vector can help you with polar <=> cartesian conversions? There are methods to set or get a vector's heading and magnitude.

Sometimes I go into a #CreativeCoding session wanting to make something specific. Other times I wonder what will happen if I try something weird

This is one of those. I use #Py5 to draw short lines on the screen, then capture the pixel array in a #NumPy array. Then I use the NumPy command roll to literally roll those pixels values around the array writing them back to the canvas when they are in different positions. This is the result after thousands of positions

Various blended colors forming many overlapping peaks and valleys, as if entire mountain ranges were flattened into a 2d image and you could see through them. This one is a lot darker with many more deep blues and dark purples

@TomLarrow very creative process!

Started preparing a new release and found a bug. Release testing is important! Happily this is an easy fix. Will delay the release till next weekend though...

Some in for today. I took yesterday's sketch, converted the points to triangles, and shaded them with various densities of random points

Code: https://codeberg.org/TomLarrow/creative-coding-experiments/src/branch/main/x_0082

Various triangles each shaded differently seem to form a snake like pattern that seems curl along the left hand side, along the bottom of the image, and through a large loop on the right
Various triangles each shaded differently seem to form a snake like pattern that is very chaotic swirling all over the canvas
Various triangles each shaded differently seem to form a snake like pattern that seems to move from the bottom left towards the middle, up to the upper left, down to the middle center, to the upper right, and makes an S shape in the bottom right

@TomLarrow these have a neat aesthetic!

@Timteachesmath Sir, do you have a minute to hear the word of our lord Processing + Python that came amongst us as py5coding.org ?

Check out https://abav.lugaralgum.com/como-instalar-py5/index-EN.html

@Timteachesmath @villares py5 does work well in Jupyter Notebooks and you can use it over the web using JupyterHub servers such as mybinder.org.

The documentation for the next release of #py5 is now complete...on track to release 0.9.1 by the middle of July. Stay tuned!

Some #CreativeCoding this morning. Use Poisson Disc Sampling to grab some points around the screen. Then I sort them and try to assemble them into shapes. I used the shapely library to calculate their areas and apply colors based on their size. #Py5 #Python

Code https://codeberg.org/TomLarrow/creative-coding-experiments/src/branch/main/x_0077

Many 4 pointed shapes mostly in earth tones of brown, olive green, tan combine to form an abstract shape.
4 pointed shapes in deep red, blue and grey form together that sort of looks like a dog with it's tail in the air (if you use a lot of imagination)
triangle and quadrilateral shapes of dark blue, deep red, and green come together to form something that sort of looks like a crown

@TomLarrow Nice work!

Did you know that the begin_shape(), etc commands can be used as context managers? You can do this:

# Draw our quad  
with py5.begin_closed_shape(py5.QUAD):  
 py5.vertices(quads[i])

This works for Py5Graphics and Py5Shape objects as well.

Also, the Py5Graphics object has a lines() method that is analogous to the py5.vertices() method you used.

@TomLarrow Indeed! Life is amazing that way

I was trying to work on some #CreativeCoding last night, but I wanted more control over noise generation than what I could find in the @py5coding libraries. So I wrote my own simple code to give me control over Open Simplex octaves, frequency, and persistence (after I learned what all those are) Same open simplex seed on all of these, just different variations of the other values on each #py5

Code: https://codeberg.org/TomLarrow/creative-coding-experiments/src/branch/main/x_0072

The blobs a bit more cloudiness to them as other details appear. This is 12 octaves, with 0.3 persistence
A far more cloudy pattern. This is 12 octaves with 0.65 persistence and 2 frequency
A very splotchy black and white noise pattern. This is 12 octaves, 0.65 persistence and 4 frequency

@TomLarrow your noise explorations are great! py5's noise documentation lists alternatives to its own functionality, some of which you might find useful:

https://py5coding.org/how_tos/generate_noise_values.html#other-noise-options

The last one, FastNoiseLite, might be particularly interesting to you:

We are pleased to announce the completion of @lucky ’s project: introductory tutorials for & . Thank you, Zelle, for your hard work & dedication, and much gratitude for the Processing Foundation for your support & believing in py5!

This is a book's worth of content, and no small undertaking. If you printed out all 19 tutorials, you’d need +250 pages! An amazing contribution to the py5 community.
