Cell Shading in TGB

#1 In a 2D environment, you'd probably just pre-render your sprites in a 3D program, such as Lightwave, with cell-shading enabled. That's how I generated the karts for the Kart Kit. I think that technique works out okay.

#2 in the project i recently made, we did just that, made the models with XSI, pre-rendered them, and then took pics of the models to use them as sprites on TGB.

now, how to apply CellShading in real time in TGB i've no idea.

#3 If it uses openGL I'd think changing the rendering code to display cel shaded models would work. Probably just editing the code in T2D/t2dShape3D.cc could do the trick.

#4 problem is that in TGB, you mostly work with sprites, not with poly models... but well, i dont know much about how to apply cell shading effects so, i better shut up.

#5 Well the sprites in TGB are actually flat polygons with a texture drawn on them, from what I understand. TGB is more of a 3D engine than true 2D.. We already have the code to draw models in there. All you would do is change that rendering code to draw a cel shaded model. I wish I had time to experiment and possibly do it but I barely get to code as it is lately :/

#6 It can't be done without modifying the C++ code.

The workaround that I and others have used so far is to render your tiles at various blended levels. For instance, I have one spritesheet, then rendered it again for spritesheet_red, spritesheet_blue, spritesheet_green. Once for each shaded color that I'll be swapping out in the tiles. You could do the same thing for opacity or brightness.

#7 You could also render 2 sprites for every 1 sprite you need (do this dynamically in code). Then, in code, have the actual sprite be in front of the second. Make the second a little bit larger than the original sprite (uniform sizing), and modify its blending colors to be 0,0,0. Now you don't need any additional sprite sheets, don't need to worry about adding a black outline to all your images - the code will handle it all for you. Though keep in mind that this will effectively double the amount of objects on your screen at all times.

#8 Check out my game droneswarm (http://droneswarm.com)
I rendered my player aircraft in 3D with flat cell shading and a black outline, and then stored it in a 2D spritesheet.

#9 hey Conor, what you said was what i suggested, havin your models render with the CellShading effect and then make your sprite sheets with that... cuz i think (out of my ignorance) that doing that directly on the engine, would be a lil CPU expensive.

#10 I greatly appreciate all the comments about this topic, I will play around with a few ideas you guys said previously and see if i get anything working. I may just render it with the cell shading effect and make the sprite sheet like Casas and Conor suggested.

Sorry for the late response though, I have been in Arizona rock climbing lately. :D
