In addition to my last post with the example graph, one can also send Bifrost Object data out of the board and connect it to a Maya mesh in the DG world.
To do this one needs to create a bifrostGeoToMaya node as well as a Maya mesh (shape) node in the node editor.
From there we can connect the bifrostGraph1.output -> bifrostGeoToMaya.BifrostGeo -> polySurfaceShape.inMesh
we can see in the image above the mesh is green. This is because we would still need to apply a shader (aiStandardSurface for example) to the mesh (using your favourite method to do this).
Option 1)
A) If you install the RPOA compounds package, there should be a node called "voxel_grid_to_points" that allows you to convert volumes to points and follow the points_to_levelset that @syracoj method to get the meshes
B) If you like to build the compound from scratch, you can follow the graph in "Voxel_Grid_to_Points.PNG"
The logic is to iterate through Voxel_fog_density array and if density is above zero, get the position from the volume (you need to create "update_voxel_position" node and update the volume with point positions first). Then construct points in the newly created array. from there you can follow the points_to_levelset method again
Option 2)
Volume_to_Mesh_Optimized.ma
you can study the attached file for converting combustion volumes to mesh that can be manipulated in DG.

sorry about the confusion, voxel_grid_to_points is no longer part of RPOA.
you can use the images below to recreate your own graph or study the attached scene file.
