Request I can haz mesh normals?

[msteiger]

I have this mesh of a question mark that I'd like to use. It was created from the Noto Sans font and extruded using Blender. See this image for an illustration. However, it does not have normals. It would be great if someone could add them to the mesh so it is lit properly in the engine.

Grade C: add vertex normals so it will work.
Grade B: duplicate vertices at sharp edges so that they have different vertex normals and the sharp edges are properly lit.
Grade A: bevel the edges

Bonus points if you can briefly outline how to achieve A or B with MeshLab or Blender.

I should be able to do it, but I just do not have the time at the moment. If you don't find anybody, can you please ping me in a month?

Paging @glasz and/or @Gooey enhanced with reminder functionality

i could only do grade C i'm afraid. The normals where there, just not in the right direction, so i flipped them outside. As for bevel, the way the character was meshisized made it impossible to do it easily, it would be simpler to redo it some other way...

Thank you @glasz - it looks a lot better now:

I managed to create bevel edges for both ExclamationMark and QuestionMark in Blender. However, the mesh normals are wrong again
Maybe @glasz or @manu3d can help?

 

[glasz]

Checked the file and the normals seem ok ....maybe it has to do with the mesh being smooth shaded?

Here's a flat shaded version, see if it fix the thing....

Texture test

Very nice, @glasz

 

[msteiger]

Can you create OBJ files with two polygon groups? One for the bevel faces and one for the others?
That way, we could just render the beveled group with a darker color entirely without textures!

 

[glasz]

so here's an obj with 2 meshes, one for the main faces, another for the bevel faces

 

[msteiger]

Thank you @glasz, I think that brought be on the right track. I'm working on support for sub-group rendering now to get the new meshes in the game!

A quick preview of what it could look like:

The mesh is great as-is, the code need some serious treatment though.

Looks fine to me Is the code behind it just scary? It works!

The look of the symbols certainly works for me. I'm wondering if it's good to have them rotating though: seeing the question mark from the back is a bit funny. Could they be always facing the player instead? Also, I'd recommend to be able to toggle the bouncing off.
