Real-Time Physics Simulation Forum

I figured it out. I'm running this on Windows OS. So I need to go to the source file "SimpleOpenGL3App.cpp" function void SimpleOpenGL3App::dumpFramesToVideo(const char* mp4FileName) and change m_data->m_ffmpegFile = popen(cmd, "w"); into m_data->m_ffmpegFile = popen(cmd, "w...

Hi everyone, I have a simple simulation running with a basic opengl app and now I want to output the simulation results into a video. I followed the example here . Specifically, I used the built-in method SimpleOpenGL3App::dumFramesToVideo(Filename). To run this I downloaded the ffmpeg executables a...

Hi did you solve it? My visual studio also refuses to link the symbols lib as it is supposed to.

Hi, I was trying to start up a new simple project with GUI in a new solution using the bullet library. I created this solution by adding existed porjects (Bullet3Common, BulletCollision, BulletDynamics, LinearMath, and OpenGL_Window). Initially I was having a lot of linking errors but I resolved som...

Hi everyone, I'm wondering is there a difference between the two methods to assign an Identity to a btTransform variable? I was reading the ConstraintDemo.cpp and noticed that, when creating a btRigidBody the code used: btTransform tr; tr.setIdentity(); But when creating a frame for the constraint, ...

Hi, I am trying to implement the .obj file loading by using the tinyobj::LoadObj. The specific command I use is: std::string err = tinyobj::LoadObj(shapes, relativeFileName, materialPrefixPath); What I got from the compiler: 1>LoadObj.obj : error LNK2019: unresolved external symbol "class std::...

Thanks every one! This is really stupid. I need to set the HelloWorld as the startup project

Hello every one! I just started using Bullet, literally today. I'm a rookie, so sorry if my question is boring you :) I managed to generate vs2010 project files and solutions. But whenever I run the Bullet's HelloWorld.cpp (in Visual Studio 2017), I was automatically redirected to the example browse...
