Hi,
This error message means that you mixed together in a single
expression float's and double's. You can't do that, you must use
matrix.cast<float>() or matrix.cast<double>().
More specifically look at the innermost step:

This tells you that at line 224 in your file libsph/SPHSampler.cpp,
you are doiing an expression of the form
some_matrix * some_expression
and some_matrix has float coefficients while some_expression has
double coefficients.
The solution is to write
some_matrix * some_expression.cast<float>()
since anyway your error message tells us that you are storing the
result into a float matrix.
I realize that this is a very unhelpful error message, so we should
add compile-time logic to guard this and produce a nicer error message
if the types don't match (on my todo).
Cheers,
Benoit
