Summary: Have you ever made an interface between two -- or better yet even more -- different physics toolkits? For a online game (or at least with network physics)? How did it turn out? Lessons learned? Is it better to rewrite large chunks of code elsewhere, or did the investment pay off? Bloat: I'm using ODE physics toolkit for my in...
I have some differential equations that I need to solve using MATLAB's ODE solvers. While the differential equations themselves are fairly simple, they depend on a lot of "constants". These constants aren't universal, and need to be supplied by the caller. An example ODE of this sort would be: dx/dt = -j * (k + x) ./ (l + x) Where j,...
I'm trying to make a bowling game simulation for college. Any ideas where to find a decent tutorial in DirectX9, using ode-0.9 and c++? ...
I've implemented a system of web services using Eclipse / Apache Axis2 / GlassFish. Now I need to extends the system's functionality through BPEL. What's the most straightforward way of achieving this? I've found numerous examples on how to use BPEL in Apache ODE, so should I add ODE to my existing application (and, if so, how)? I woul...
Hi, i am trying to build APACHE ODE source code with Buildr using Ruby. I installed ruby and installed Buildr with it, but when i run the command rake package on the root of APACHE ODE source code it gives me this error C:\workspace2\APACHE_ODE_1.X>rake package --trace (in C:/workspace2/APACHE_ODE_1.X) rake aborted! uninitialized consta...
I want a python physics engine that works on mac and makes it easy to simulate physics. I have VPython and it works fine, but it is not quite what I want. VPython just shows visual elements and all the physics is in formulas. I looked at the documentation for PyODE and it looked like more what I want. It allowed you to add forces to mass...
I am trying to install ode via Macports, but get this error: On Mac OS X 10.5, ode 0.11.1 requires Xcode 3.1 or later but you have Xcode 3.0. Error: Target org.macports.extract returned: incompatible Xcode version Is there any way to install ode without xcode 3.1? ...
HI, I want to access wsdl file that is imported in bpel definition, can i do that or i will have to create local copy and then use it? Because whenever it run the process it gives me this: FATAL - GeronimoLog.fatal(116) | openResource: invalid scheme (should be urn:) http://localhost:9090/axis2/services/Inverse?wsdl I am using ODE en...
Hi, I'm trying to use Mathematica's NDSolve[] to compute a geodesic along a sphere using the coupled ODE: x" - (x" . x) x = 0 The problem is that I can only enter initial conditions for x(0) and x'(0) and the solver is happy with the solution where x" = 0. The problem is that my geodesic on the sphere has the initial condition that x...
Sometimes I am unable to symbolicate my application's stack frames in a crash report. This is because I do not have an older .app and .dSYM. I was trying to force XCode to use my newer .app and .dSYM as the app has not changed significantly. Is there a way to modify the UUID associated with the crash report? Is the UUID stored in file's...
I recently upgraded to XCode 4. I imported a project from 3.2 and started a build. I got two errors immediately, regarding missing documentation. The project built successfully regardless, but I'd like to remedy the issue. I compile with the core-plot framework, and the error is specific to some missing files in doxygen.app. After s...
Okay, I have this not so pretty 2nd order non-linear ODE I should be able to solve numerically. f''(R)+(2/R)f'(R)=(.7/R)((1/sqrt(f))-((0.3)/sqrt(1-f))), f'(0)=1, f(1)=1 I was thinking of breaking this guy up into a system of two first order ODE's and then solve, but I have no idea how to set this up. What method should I use to set up ...
Hello, I would like to write a function that has a loop in it which preforms the operations necessary for Euler's method. Below it my poor attempt. In[15]:= Euler[icx_,icy_,h_,b_,diffeq_] := curx; cury; n=0; curx = icx; cury = icy; While [curx != b, Print["" + n + " | " + curx + cury]; n++; dq = StringReplace[diffeq, "y...
