mass radius of sphere

[Tamás Király]

hi,

i have a sphere and plane setup with gravity. i expect that the sphere will bounce back from the plane but this is not always the case. it depends on the radius of the mass of the sphere. i might miss some math here but don't get it why the mass radius changes the bounce behavior radically.

this is my sample code: https://compusciencing.github.io/starting-with-ode.html

i change radius to a number about 1 in this line:

dMassSetSphere(&sphere_mass, density, radius);

and the bounce does not work.

any idea?

thanks

Tamás
