BumpMapGenerator avaible!?

[martin]

hello,
is in away3d a bumpmpgenerator avaible? i want to create a normalmap
with appling a bump on runtime.
generating a normalmap from my source image is no problem, but i want
to use the applybump-method from the normalmapgenerator class and the
bumpsource should come from the original image with an generator or
other function.
thx
martin

Hi Martin,
I'm not sure I do understand your question...

but may be you mean this?

var nmg:NormalMapGenerator = new NormalMapGenerator();

bm:BitmapData --> bumpmap
nm:BitmapData --> normalmap

nm = nmg.applyBump(bm, nm);

Note that the volumetric bump available in Prefab with variable height
is not available in the trunk yet.

this is clear
+ var nmg:NormalMapGenerator = new NormalMapGenerator();
+ bm:BitmapData --> bumpmap
+ nm:BitmapData --> normalmap
+ nm = nmg.applyBump(bm, nm);
but this line "+ bm:BitmapData --> bumpmap" - i want does't use a
library source, i want to creat at runtime a bumpmap from my texture.
is this possible in away with the api, like this "var
bitBump:BitmapData = bumpmapgenerator(source);"
thx

this was pseudo code,
I assume here you do know how to generate/load/access a bitmapdata
object.
If not reffer to AS3 general documentation.

> is this possible in away with the api, like this "var

no. use the code provided in previous mail
just change these line with non-pseudo code

> bm:BitmapData --> bumpmap
var bm:BitmapData = someFunctionthatReturnMeTheSourceBitmapData or
BitmapDataObject.

b & m stands for this example as Bump Map
n & m stands for this example as Normal Map
