Import 3DS meshes without faces/edges

Importing a 3DS mesh without faces causes crash of ZGE (access violation, read of address 00000000). It would be nice that also meshes having just vertices can be imported and managed in ZGE; maybe more optimally than meshes with faces. This makes sense especially in the case when materials use Point shading. Testing 3DS file is attached.

Hi Rado1,
The 3DS file format only supports triangle meshes.

I tried importing your 3DS file in a number of applications, and all of them threw a error .. so i suspect the file is invalid ( by 3DS standards ).

Aha... I created it in Blender and Blender was able to import it back, so I thought it's correct. But if not, of course, this request makes no sense.
BTW in meantime, I created own file format for vertex-based meshes (it stores list of vertex position, normal and color), converter from ZGE meshes to that format, and dynamic importer of mesh files to ZGE, so now I can create own vertex arrays (VBOs) and do not use ZGE meshes which draw a single vertex several times...
