It solves the differential equation system using the standard 4th order runge-kutta method and allows you to edit the initial conditions within a certain range. It also displays the angular position of both masses on a plot, so it gives a certain intuition of how the system behaves. </p> <p>Hope you like it!</p> Sun, 20 Dec 2020 17:22:13 UTC Heat 2D <p> <table><tr><td> <a href="/bbs/?pid=84295#p"> <img src="/bbs/thumbs/pico8_heat2d-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=84295#p"> heat2d</a><br><br> by <a href="/bbs/?uid=21804"> luihabl</a> <br><br><br> <a href="/bbs/?pid=84295#p"> [Click to Play]</a> </td></tr></table> </p> <p>Hi everyone! </p> <p>I made this simple 2D heat simulation to experiment a bit with PICO-8. It solves the steady-state heat transfer equation iteratively using the Gauss-Seidel method and it shows the evolution of the solution at each step. During the simulation the fps gets a bit low since the grid is fairly big (128x128), but anyway I think it gave an interesting result so I decided to post here! I hope you like it. </p> <p>You can edit the configuration of the simulation using the mouse functionality to add or remove high and low temperature boundaries. If a boundary does not have a fixed temperature block it is considered an open boundary (dT/dx=0 or dT/dy=0). </p> <p>Thanks and all feedbacks are very welcome! </p> Sun, 15 Nov 2020 21:56:36 UTC FISHBONE <p> <table><tr><td> <a href="/bbs/?pid=84171#p"> <img src="/bbs/thumbs/pico8_fishbone-0.png" style="height:256px"></a> </td><td width=10></td><td valign=top> <a href="/bbs/?pid=84171#p"> FISHBONE</a><br><br> by <a href="/bbs/?uid=21804"> luihabl</a> <br><br><br> <a href="/bbs/?pid=84171#p"> [Click to Play]</a> </td></tr></table> </p> <p>First game using Pico-8! So happy I could finish a game by myself and actually post it.<br /> Anyway, hope you enjoy despite of being super simple and of course let me know if you have any suggestions for the future :)</p> Thu, 12 Nov 2020 21:53:24 UTC
