A HealPix implementation for ROOT is available at https://github.com/akira-okumura/RootHealPix. You can compile that into your Mars libarary.

After checking out Mars from the repository (see InstallingMars), simple extract the attached zip-file into your Mars source directory or get RootHealPix from git:

[0] cd Mars
[1] git clone https://github.com/akira-okumura/RootHealPix.git

If RootHealPix is located in your Mars source directory, cmake should find it automatically and compile the healpix classes into the Mars library, otherwise call cmake with the corresponding path:

[2] cmake -DHEALPIX_PREFIX=<path-to-RootHealPix>

To test the installation, start root in your Mars build directory and try something like:

THealPixD hp("name", "", 2); 
for (int i=0; i<10000; i++) 
   hp.Fill(gRandom->Uniform()*90, gRandom->Uniform()*180); 
hp.Draw("COLZ");
