Pixel shaders independant of object angle

[MechatheSlag]

So I was wondering if it's possible (or will be possible) to apply pixel shader effects to active objects in a way so that they DON'T follow the active object's angle?

[xyzzy]

not like i'll know the final answer but it's sort of possible by moving the rotation to the shader itself

this of course brings up its own problems such as the object's corners being chopped off unless you add a lot of blank padding space

What are you talking about following its angle? If you mean making it so it rotates first, then applies the shader, what you could do is make the rotation part of the pixel shader.

okay so let's say I didn't make this pixel shader

what would I do to make it rotate?

[Dynasoft]

You wouldn't

Sorry for the hole one, it really is too much math for ps 2.0
I can't optimize it so it's under 64 operations...

[MechatheSlag]

You wouldn't

so what you're saying is that it's impossible for me to achieve?

[LazyCoder]

Not without editing the pixel shader.

Not without editing the pixel shader.

I never said I wasn't willing to do that. I just asked what I would, like, do in the pixelshader's code in order to achieve that.

Well first what you'd need to do is rotate it in the pixel shader's code first (and you can look at one of sphax's shaders to see how that's done). So it's really almost all copy & paste.
