Need help about displacement map as3

Hi

The displacement map filter is a flash built feature that can use for some special effects.

Displacement mapping is a computer graphic technique in contrast bumps mapping, parallax mapping, and normal mapping using texture.

The DisplacementMapFilter uses a pixel values from a Bitmapdata object to perform a displacement effect on a new object.

You should know following components.

Map point: you can use this when you want to apply filter to your image.

X component: which color channel map the image effects the X position of pixel.

Y Component: which color channel of the map image effects the Y position of pixel.

X scale: specify the how strong the X axis displacement.

Y scale: specify the how strong the Y axis displacement.

Example: offset = new flash.geom.point(0,0) – (this will define a new point for the offset of the displacement map)

Displacement_map =new flash.filters.displacementMapfilters(bmp,offset,chaneel)

(This will create the displacement map itself)

Bmp=new flsh.display.bitmapdata(500,250);

(this will draw the displacement map un the bitmap data)

Thanks & Regards
