That was the effect i wanted, so now I'm trying to make a color gradient to put to the letters.

good work!

if you remove the contents of framework64k\bin\v8\x86\Debug your uploaded .zip file will be a LOT smaller    (mainly the pdb/obj/idb/bsc taking up space)

Ok thanks for the advice!

Great stuff lucastar \o/

Looking forward to see how you did it

Thanks!!

OK, in the source is the Test() method in bmpFont.cpp class.

I will try to explain myself well (please see the attached image):

We draw the first quad, and the next one must have:
the left-top point = right-top point from the previous quad;
the left-bottom point = right bottom point from the previous quad;

then the right points = right points from the previous adding:
to the x coordinate, the size of the quad
to the y coordinate the yOffset.

The yOffset is calculated this way:
float yOffset = sin(time - x/*one of the two x point values*/ * n1 ))*n2;
n1 and n2 are float values.

Sorry for my terrible English, and if you have any questions please ask!

I did it!!!
The method is very simple, here is the example, and later i will upload the code and an explanation.

I am very happy because in the end i did it in a home-made way.

Thanks ninogenio! Now i'm trying to do the char stuff...
If I make it, i will upload results + code.

Very nice, that is low-level programming!

I think I've got it   
Not very nice, but i think this is the correct way.

Modify: of course nothing of changing char shape...

Yes, that is what I'm trying to do right now. 

I wouldn't worry too much about changing the character shape yet. Sure, you can do some really cool stuff like make it warp in the Z plane, so that it bulges towards and away from you, but leave that until later.

So... it must be very difficult am+ i right?

I can't do better than this. No idea about how to change the character shape, only how to make a wave...
I have tried to do it with vertex shaders too, following the tutorial, but it only worked when drawing 3d objects.

Thanks Raizor! this is very helpful!!
As soon as i get the results i want i will upload the code.

Thanks again!!!

I thought the vertex shader was the one to use for vertex transformations, and to do the wave effect. Fragment shader is not more about color and texture stuff?

I should probably also ask, what are you expecting to see on screen?

In first place i tried http://zach.in.tu-clausthal.de/teaching/cg_literatur/glsl_tutorial/#flatten, but it didn't work.
Then i tried to create a shader that did nothing(I think):

Code: [Select]

void main()
{

gl_Position = ftransform();
}
It doesn't work either. When i say that don't work, i mean they are loaded and compiled correctly, but then nothing shows up.

I'll have a look in a min lucastar. I stupidly uninstalled all versions of visual studio other than 2012 the other day, so you probably won't be able to open the project once I edit it (unless you have vs 2012?). I should be able to at least find the issue and point it out though. Fingers crossed

No, i don't have it, but i can get it on Thursday. If it is easier to you tell me.
Thanks!

I think there's no problem with that... but i didn't code the shader loader (i think Raizor is the author), so i'm not sure.

I've been trying all day to use GLSL... i create a shader, i compile it, but i can't get anything showing on the screen.
I upload the code so if anyone has time to take a look and help me, i will be very grateful because i don't know what is wrong.
Thanks!

Ok, i got a cute wave effect, but i can't get the character distorsion right.
Here is the example, for anyone who wants to try.
The method is _DrawChar on bmpFont.cpp class, and the z rotation seems to be working ok.
Sorry about the huge .rar size...

Thanks to all, I'm trying to emulate that movement... it's difficult, I'm thinking about using GLSL xD.
As soon as i get close, I'll upload the SC.

Works fine here lucastar, on Win7 x64 with a GTX 580 card.

Curious to see how it looks when scrolling across the screen 

thanks Raizor, i used your font classes to load the image and bind the texture correctly  .

Ok, i did it canopy's way. The effect on the demo is good, but not exactly which i wanted. The position and z orientation change, but shape doesn't.
I will try to add the FBO stuff, and if it does not work, try the GLSL way.
Uploaded the executable file, i don't know if it works on another PC, please try
