TODO

• get object rotation: 3 Euler angles. Attempt made at gravity.cpp
• get object velocity and angular velocity
• what is the point of motion state?
• Stairs physics: http://gamedev.stackexchange.com/questions/74794/make-the-player-run-onto-stairs-smoothly
• Voronoi: https://www.youtube.com/watch?v=FIPu9_OGFgc
• substeps vs smaller time step on stepSimulation?
• opengl visualization
  • rendering is done from https://github.com/bulletphysics/bullet3/blob/2.83/examples/ExampleBrowser/GL_ShapeDrawer.cpp in immediate mode
    • TODO what happens then?
    • from https://github.com/bulletphysics/bullet3/blob/2.83/examples/ExampleBrowser/OpenGLGuiHelper.cpp#L447 renderScene
    • m_guiHelper is set called from OpenGLExampleBrowser to a OpenGLGuiHelper
    • CommonRigidBodyBase::renderScene() calls m_guiHelper->render(m_dynamicsWorld);
    • BasicExample:: CommonRigidBodyBase::renderScene(); calls CommonRigidBodyBase::renderScene();
    • colors just alternate between 4 values: https://github.com/bulletphysics/bullet3/blob/2.83/examples/ExampleBrowser/OpenGLGuiHelper.cpp#L117
• user input
• 2D

  • an SDL demo with mouse drag generating forces proportional to initial drag point distance on object would be easy and neat to do
