Jan 30, 2024 Replies: 4 Have converted this Processing Github Project to B4J. Very interesting to watch this being drawn in real time. Just B4J default libs required. Have not used the default Processing PVector library for the project - have hard coded the Vector multiplication, subtraction, addition, dot product, magnitude, normalization, etc inside the B4J project. Enjoy! 50 rays 100 rays 1000 rays Attachments b4jCausticRaysCircle.zip b4jCausticRaysCircle.zip 2.6 KB · Views: 504 Last edited: Feb 2, 2024 Click to expand...

Johan Schoeman Expert Licensed User Longtime User Feb 18, 2024 #5 The attached B4J project will randomly select a ray starting point and then a randomly selected "first bounce" point and then continue to bounce the ray according to the "laws of reflection inside an ellipse". It draws some interesting patterns inside the ellipse baaed on the randomly selected start and first-bounce points. Makes me wonder why the Oval Office is an oval office....?
