Re: [eigen] Supported scalar types on Eigen

First of all, thank you very much for your fast and useful answer.

I want to use a vector of unsigned int triplets for vertex indices in an OpenGL application, and i can't use ints with glDrawRangeElements().

Thank you!

Hi Jose,

indeed, by default you cannot use unsigned types because we did not see any use case for that. Actually I can see some use cases for unsigned char and unsigned short, but for int ? Do you really need unsigned int instead of int ?

anyway, adding the support of any custom type is trivial, and there is a tutorial in the API doc:
http://eigen.tuxfamily.org/api/CustomizingEigen.html#CustomScalarType

Hello!

I'm using Eigen2 for a practice at the University, and I'd like to use this kind of Vectors:

typedef Matrix<unsigned int, 3, 1> Vector3ui;

But it returns a lot of errors during compilation. Can't I use unsigned types with Eigen Matrices?

Thanks for your great job!
