#44 eigen.h is too old

[Anonymous]

vcg\math\eigen.h is quite old to compile with newest Eigen3,there are a lot of deprecated functors like "ei_scalar_add_op","ei_scalar_product_op"..., I found that these structs are in Eigen2

Can you help me?

I set the preproces command "VCG_USE_EIGEN", and get the compiling error:

D:\3rdparty\vcglib\vcg/math/eigen_matrixbase_addons.h(134): error C2065: “ei_scalar_add_op”: undeclared

environment: vs2010, vcglib

I have succeeded to complie the vcglib code without the preprocess command "VCG_USE_EIGEN".
