pub type b3TreeRayCastCallbackFcn = Option<unsafe extern "C" fn(input: *const b3RayCastInput, proxyId: c_int, userData: u64, context: *mut c_void) -> f32>;Expand description

- return a value of 0 to terminate the ray cast
- return a value less than input->maxFraction to clip the ray
- return a value of input->maxFraction to continue the ray cast without clipping
