iGravity is a small Java-Cocoa Application that simulates Gravity with small Masspoints. It takes place in a 800*600 pixel area. You can add masspoints with initial velocity, mass and location or you can add fixed masspoints. You can show/hide Acceleration and Velocity Vectors You can set Gravity Constant You can enable and disable 3D (with or without glasses) Besides it's lack of speed there are a lot of bugs in this program (Zoom doesn't work exactly with 3D-Glasses, no open/save possibility, Reflection at borders causes jumping masspoints which are outside of the 800*600 borders... ) |
