Model Tranparencies...

[Misery]

I think (in a modeling standpoint) that transparencies on cycle models would be a wonderful thing! I know as of now, it is not supported. But are there any plans in the future to make it so? Or would it be possible? Take for instance... Someone is making a model of say.. a skeleton. You COULD model all the ribs and such individually, but depending on hardware, that could seriously hurt the frame rate of the game. It also can be done by making a low poly cage for the ribs and making a rib texture. But without transparencies, it looks like a black block painted with ribs. With transparencies, you could model the ribs in the same way so it would actually look like a skeletons rib cage.

I'm sure this has been touched on before, but I think it would also be a nice idea to have a roster of different cycles. Something like choosing your player models in <insert FPS game name here>, or any other game like that.

Wishful thinking aside... model transparencies WOULD be awesome! Possibly? Maybe?

Could you conceivably make a cycle model with a somewhat transparent canopy? Alpha channel on cycle wheels drums up interesting possibilities too... I support this idea! Too bad I can't support it with code.

Ooooo.. OOooooo.... Animated models! More than just rotating wheels. Just another though...

[sinewav]

While were at it, animated textures too!

[Word]

glowing, mirror/reflexion effects, reliefs, fog, global illumination, diffusion, fresnel refraction....everything!

Let's start with fitting this sort of thing on the 'engine' without too much duct tape:

Code: Select all

// texture contents compared to typical rgba: rgba' = vec4(a*r, a*g, a*b, 1-a)
uniform sampler2D texture;
uniform vec3 color;

void main()
{
	vec4 sample = texture2D(texture, gl_TexCoord[0].st);
	gl_FragColor = vec4(sample.rgb + sample.a * color, 1);
}

C'mon Word, let's not be greedy. Baby steps, man... Baby steps. lol

Jonathan, as for that code... I haven't the slightest clue what that is for. Have a good idea, but that's about it.

/me programming dummy.

[Jonathan]

It's a simple pixel shader that blends the cycle texture over a cycle's color. Because right now, every cycle gets its own texture with its color baked in. My shader does it on the fly, and it's dirt cheap at that.

Basically, get shaders going! Also a subliminal message to use premultiplied alpha, the undivided approach to alpha blending.

[Misery]

So can/will that code thingy (Yes, I said 'thingy'. heh) be implemented in future releases?
