:FWIW, I suspect the Wren and Phix output corresponds to the "gaps" in the input, and maybe the (quite blatently deliberate and easily undone) negative Y result is somehow supposed to indicate that? --[[User:Petelomax|Pete Lomax]] ([[User talk:Petelomax|talk]]) 20:43, 30 June 2022 (UTC)
::If I understand right, the result that we are expecting should correspond to positions half way between pixels. Looking at the wikipedia entry, we should be working with an intermediate result something like this:
<tt>
:: 0 0 0 0 0
:: 0 2 3 1 0
:: 0 6 15 9 0
:: 0 4 14 9 0
:: 0 0 4 8 0
:: 0 0 0 0 0
</tt>
::But then, according to the wikipedia page, each of those integer values get expanded into collections of pixels. And that's not what we are seeing here with any of the current task implementations. --[[User:Rdm|Rdm]] ([[User talk:Rdm|talk]]) 11:33, 1 July 2022 (UTC)
==Oval of Cassini==
It is always difficult when a task is submitted with no implementation and just a reference to Wikipedia, especially if the task's author does not then engage in the discussion. I suggest the task description should be expanded to in include an example, and that that example should be [https://en.wikipedia.org/wiki/Cassini_oval Oval of Cassini]. The task being to use Marching Squares to produce [https://en.wikipedia.org/wiki/File:Cassini-3kurv.svg Expected Output].--[[User:Nigel Galloway|Nigel Galloway]] ([[User talk:Nigel Galloway|talk]]) 14:36, 1 July 2022 (UTC)
