CUDPP Sorting Vertices

[Larry35]

Hi all,

I need to sort vertices according their distance from a defined point. Given that my struct looks like this :

struct
{
float distance; // distance from the viewpoint
unsigned int index; //index of the vertice in the array to sort
}

I’ve been looking at the CUDPP documentation and it seems that CUDPP doesn’t handle this kind of input ?! :unsure: ( sorting according distance but giving the result through index )
Am I wrong ?
Do you have any clues to perform this by another way ?
Thks,
Larry

AFAIK yes, CUDPP does not support key/value sort, but there’s been some discussion of it in the friendly though low-traffic CUDPP mailing list: http://groups.google.com/group/cudpp
