All Hearts That Are Gems Do Not Glitter,      Not All Those With Blackbane Are Lost; Slaves That

mmm..  I distinctly don't need more projects right now, but I can tell you what would help get stuff that I have already drawn (and likely that other people have drawn) or am planning to draw anyway onto the wiki. 

 Make a "Welcome Fanartists!" page (or something like that)  that is easy to find from the main page. This page should first and foremost have simple detailed instructions for how to add art to the wiki.  These instructions should assume that the person has no idea how to edit the wiki at all.  If there is someone who is willing to add art that they are pointed to, you might include instructions for how to tell that person that your art is available to be added.  If there are any ground rules for what kind of art should/shouldn't be added, include it here.  

After that section, it might be useful to have a list of "things it would be nice to have art of" that fan artists can go look at when they feel like arting but aren't sure what they want their subject to be.  If you wanted to, you could have these grouped into a couple of different priority levels (perhaps: It's a disgrace that there is no art on this page, it would be helpful to have art on this page, this page has some art but could use more, this page could use art if it happens to be something you are excited about drawing).  If there is a way to have them in a table so they can be sorted by priority level, planet/book, or type of thing (maybe: people/plants/animals/things/other) that could be useful. That way if someone is thinking "mmm I want to draw a Mistborn character" or "I want to play with the plant life on Roshar" they can look to see what we could use.

Once you get that page functional, throw it to tumblr with a short list of pages that could use more art.

Cosmere artists! I seek your opinion!!

If there were some notice/notification on wiki pages which pointed out or asked for art to be given for a particular topic or section. EG the Shardplate page has no art, and would probably very much benefit from some, to help describe it. 

Would people be ok with requests like that, and would artists actually contribute more than they already do?

I just want to increase the contributions and make it a more informative source and make editing and helping out more attractive and easier? I don’t know what I’m doing tho really. Please help XD

The first oath of the Knights Radiant at the request of sprenborn :D I kinda went all out for this one and I really like how it turned out

kalynaanne made a much needed edit to this photo and I can’t thank her enough 

My immediate reaction to seeing this:  Grab my ever present notebook and copy it down so I don't have to keep flipping tabs.  Open the Coppermind.  Translate.  Grin.

an urgent PSA to the cosmere fandom

Hey Cosmere fandom, it’s book rec time.

The book series in question is the Imperial Radch Trilogy by Ann Leckie. In order, the books are Ancillary Justice, Ancillary Sword, and Ancillary Mercy.

It’s a space opera with significant focus on character and relationships. The POV character is Breq, an aro-ace space warship AI in a human body who sets out on an impossible journey to kill the Lord of the Radch (the local 3000 year old space emperor) to revenge her beloved Lieutenant. Along the way she (unintentionally and reluctantly) collects people (humans, ships, aliens,…) in a gloriously messy found family.

* It’s super queer 

* Characters actively struggle with depression, anxiety, addiction, etc.

* Almost everyone is a PoC

* For the sake of Propriety everyone wears gloves and bare hands are super scandalous. 

These books are amazing and you should strongly consider reading them. The audio book versions are also fabulous.

If you’ve already read them, I’ve been Radch posting on my other blog (RithmatistKalyna) and I would love to talk with people both about the books/characters/tea sets/etc and all of the Cosmere crossover potential.

Merry Christmas! And I hope that any of you who don't celebrate Christmas have a wonderful day as well :-)

So... I was experimenting with the watercolor brushes in FreshPaint and playing around with ways to get different effects for skies...and then this happened... so here, have a happy playful skyeel flying through the sunbeams with its little fishy spren friends.

This feels like a crazy long shot, but do I know anyone who plays Pokemon Go in the Uxie region?

Gonna attempt Febroary, a snow lep for day 1 !

Rithmatics: Part 6, 9 Point Conics and Triangle Centers

Note: From this point on we are drifting farther and farther from what we know from the book. The math is all solid, but its application to Rithmatics is much more speculative.

In rithmatics, the 9-point circle plays an important role in constructing lines of warding and identifying bind points.  We also know that there exist elliptical lines of warding and that they "only have two bind points."  Now, in math we are frequently told things like "You can't take a square root of a negative number", which are true in the given system (real numbers) but not true in general.  The construction for the 9-point circle, as described in the book, doesn't work for ellipses.  However, there is a generalized 9-point conic construction.  To understand it, we need to start with a little bit of terminology.

A complete quadrangle is a collection of 4 points and the 6 lines that can be formed from them.  For our purposes, we will be concerned with complete quadrangles formed from the vertices of the triangle and a point inside the triangle.  The 6 lines are then the sides of the triangles and the three lines connecting the center point to the vertices.

The diagonal points of a complete quadrangle are the three intersection points formed by extending opposite sides of the quadrangle.  If we have a triangle ABC with center P, then the intersection of AB with PC is a  diagonal point.

If you take the midpoints of the 6 sides of a complete quadrangle and the 3 diagonal points of that quadrangle, these 9 points will always lie on a conic. This conic is the 9-point conic associated with the complete quadrangle.

Note that if we choose our point in the center of the triangle to be the point where the altitudes meet (known as the orthocenter), then this construction is exactly what we have been doing to create 9-point circles.

There are four classical and easily constructable triangle centers - the orthocenter, circumcenter, centroid, and the incenter.  There are over 5000 other possible notions of the center of a triangle, but most of them cannot be easily geometrically constructed and they get increasingly complicated. 

Let's look at each of these 4 triangle centers and the conic they produce for a particular triangle. We will use a 40-60-80 triangle in each case for illustration purposes, but the results will be very similar for any acute triangle with 3 distinct angles.

Orthocenter: We already know about the orthocenter (that is what most of this series has been focused on so far).  For reference, here is what the 9-point circle for this triangle looks like:

Circumcenter: The circumcenter of a triangle is found by finding the midpoint of each side of the triangle and drawing in the perpendicular bisectors.  The points where the perpendicular bisectors meet is the circumcenter.  Note: This point is also the center of the circle that can be circumscribed around the triangle.

Unlike with the orthocenter, the lines we use to construct the circumcenter (the dashed lines in the diagram) are not part of the complete quadrangle, so we have to finish the quadrangle after we have identified the circumcenter.  The resulting conic is an ellipse.

Centroid: The centroid of a triangle is formed by finding the midpoint of each side of the triangle and connecting it to the opposite vertex.  The intersection of these median lines is the centroid.

The lines used to construct the centroid are part of the complete quadrangle, but we have the interesting situation where the centers of each side are also the diagonal points of the complete quadrangle.  This means that, regardless of the triangle used, we will only ever have 6 distinct points.  The resulting conic is an ellipse that is tangent to all three sides of the triangle.

Incenter: The incenter of a triangle is the intersection of the  angle bisectors of the triangle.  

Note that the lines used to construct the incenter of the triangle are also the additional lines of the complete quadrangle.  In addition, as long as the angles of the original triangle are distinct, the 9 points in the construction will all be distinct.  The resulting conic is an ellipse.

In Summary:  There are lots of ways that we could potentially construct a 9-point ellipse from a triangle.  Of these options, I would guess that the construction using the  incenter of the triangle is the most likely to produce valid rithmatic structures.  I lean this way because, as with the orthocenter, constructing the incenter also constructs the complete quadrangle and its diagonal points.  Furthermore, the 9 points of the construction will all be distinct (except in special cases). As such, we will explore 9-point ellipses constructed with the incenter more thoroughly in the next post.
