Hi, this is a good example. Thanks for sharing.
I want to ask why you prefer to use transformation matrix instead of using displacement map filter with perlin noise for the effect?
Is there any pros?
Hi Altay,
Thanks for sharing your ideas. I guess that you have seen the waving flag example from Senocular website, and they use perlin noise.
BTW, I want to control the shapes of flag by my own equations, so by using matrix I can do it. But if I use perlin noise, I can not control the flag's shapes.
Perlin noise help the flag waves in the natural style, and use the computer resource less than the matrix transform. But you can not control the shape.
If you want to make the flag waving in the natural style, I suggest you to use displacement map filter with perlin noise.
Cheers,
Physica
This is a hard way to wave a thing, but as you say you can have more control on the slices of the bitmap image.
A different and interesting way to do... Thanks again.
how do i change x,y position of this image...?
