Just noticed a bug of the polygon splitting in the OpenGL renderer. Whenever I start the emulator with this option checked, the emulator forget to apply the effect and the graphics stay buggy anyway.

The only way to "fix" it is checking the option off and then checking it back on. ![[image]](https://cdn.discordapp.com/attachments/687009184830455858/867065736933277699/unknown.png) |

im still a bit confused as to what exactly polygon splitting does as google doesnt exactly explain what it is , does it like try to smoothe them out or attempt to make them less..polygon-y or something like that ¿ im not seeing any difference in the two photos ____________________ petrol for breakfast |

If you check the character in the center of the screen closely, you'll notice that in the first screenshot he's bugged, while in the second screenshot he isn't.
Polygon splitting is a method that combines 2 triangles to form a quadrilateral (since the DS works with quadrilaterals instead of triangles). Most GPUs only work with triangles thus making the image bugged, this method prevents that. |

polygon splitting isn't perfect, it's just a sorta-fix. basically, for polygons with more than 3 edges, it finds the center and divides the polygon into triangles going around the center.
anyway, seems there's a bug in the UI or something? I'll have to look into it. ____________________ Kuribo64 |

Not a bug in the UI, but in the emulator itself. I you check the polygon splitting on in the OpenGL it'll work normally. However, next time the emulator starts, it will forget to apply the effect. |

Posted by Wifall i did see the character yea , i just assumed that was part of his character animation changing between two sprites , although since the character looks to be sprite based i would imagine polygon splitting wouldnt do anything as the sprite has no polygons , just a 2d image . i could be completely wrong though ____________________ petrol for breakfast |

the sprite may be rendered by the 3D engine, in which case it is still a polygon technically (generally a quad). ____________________ Kuribo64 |
