That should be enough information to get you started with. There is a specific question on GLSL cel shader right here in GameDev.SE: Is there any opengl cel shading tutorial out there (without GLAUX)?. OpenGL has GLSL - OpenGL Shading Language.ĭirect3D has HLSL - High-level Shading Language.Īs for tutorials and guides, there are plenty ( GLSL, HLSL), due to the release of Borderlands and huge amounts of Indie studios started the past years, the information available about cel/toon shading is aplenty. Both of these have shader languages implemented, that can do your kind of manipulations and many others. 3D GamesĪs for 3D applications, rendering is done either by OpenGL or Direct3D. Though, for a software rendered application I'd suggest that you ask your graphics artists to make such sprites out-of-box.Ī quick google search gave me these results. That won't be nowhere near fast, but it's doable.

2D Gamesįor 2D applications, using software rendering, you could achieve this by applying a per-pixel modification. The ones that aren't hobby projects should actually have such shader available in their standard assets ( Unit圓D has those dupped Toon shader).īut, the power behind the cel shading is shaders. Well, that should be possible in every engine out there. Heres how I make my props look like theyre from a video game thats recreating the look of a comic. But I cant find the defaultpostprocess in this games williowengine ini file. On top of making the game look better in my opinion, it also made the game run better on low-end computers like mine. I'm not sure if that's the right term, but I think that's what it's called. There might be something more to it, but in general, all of your examples use Cel shading to some extent.Īs for your question, whether there are any engines that support this. In borderlands 2 and TPS you can change the defaultpostprocess in the williowengine ini file to remove cell shading. I'm ok with the art style in the game, but it just so happens I liked the graphics better without the overt cell shading.
