Hi all...

Im creating a 3d game with pixel art-like texture. But i think outlining the 3d mesh will make the result look even better. Any body have any modelling or any other trick to fake outline beside using shader (which i have 0 knowledge about it)

Thanks.

You have to use a shader because the outline that the viewer sees is different depending on the angle. It isn't just the edges of the model.
But like you, my shader knowledge is 0. Check out the stickied shader thread in AppGameKit Product Chat.

Thanks BatVink...its look like i need to erase that kind of effect from my game i ever learn C++ but quit when reaching pointer, link list etc etc..hahaha.. but i guess shader can be access once i learn C++ which take time to learn.. Thanks again

If you find an outline shader (usually part of a cartoon shader) then there are people here who can probably make it AGK-compatible for you.

Or you could cheat:



This use two objects but if you could always add the outline model to the main model.

I also recommend learning something about shaders. I'm no expert but I know a few basic things. I found this website useful, along with studying some of the AppGameKit specific shaders some have posted.

One slightly annoying thing when looking at older shaders people have posted is that the way the objects colour is loaded into the shader has changed (can't remember when) but if you see "uniform vec4 agk_ObjColor" you need to change it to "uniform vec4 agk_MeshDiffuse"

Nice one 29 Games..i did try flipping normal of the mesh in 3d editor but not working as i expected. Maybe i missed the SetCullMode command and will try that. This will require a good lowpoly model bcos of extra faces but should do the trick
