Hello everyone!
I’m trying to make a plane that accepts two different bitmaps and tiles them in a checkerboard style. So, one bitmap would replace the white spots on the board and the other bitmap would replace the black spots.
Is it possible? And could you help me out somehow, cause I have no idea how to start this.
I thought about making a model in Blender and then importing it in Away3D and then texture it, but then I realized that it’s too hard for me to do it since I’m a newbie at this, and I’d like to do everything in AS3 if possible.
Thank you!

I would use a simple texture made of 4 quadrants as the attachment, then enable tiling on the material and you’ve done.

Thank you for the reply!
I want to be able to change the bitmaps at runtime. If I only make them into one texture and tile it then i won’t be able to change them separately at runtime.
Like so: I click on a plane, a popup shows asking me to choose two bitmaps from a list, i select some random two and it tiles them both in the checkerboard style.
I could make a combination of all the tiles together and then use a variable to determine which combination was chosen and then use that texture, but that seems like a lot of work when you consider having dozens of different bitmaps.
Thank you for your time!

oh ok i got it now, so the solution could be generating the bitmap texture each time:
The user select 2 images
Create a new Bitmap (I.E. 1024x1024)
Draw onto it the 2 images like the pattern above
Assign the Bitmap to the material (always with tiling)
If you don’t know how to do it, i’ll write that for you when i go home from work.

Maybe two ways:
1.More planes together to be a checker,
planeA,planeB,planeA…
planeB,planeA,planeB…
palneA,planeB,planeA…
so when click one of them,do your function
2.Do something with a bitmap(your material) use mask,when the plane be clicked,calculate uvs,then do your function
I like 1

N.B. The solution 1 is not efficient because you would have a high number of objects

With mesh’s clone and material’s clone, i think away3d can do that well.If go far away enough,weld mesh,reused the parts of the mesh,will do it better.

i think that’s the solution if he need to differentiate between tiles, but if he don’t needs to know what tile has been clicked it’s better to use a dynamically generated texture.

As your say.^_^

I’m actually having problems making the popup window, it’s a lot harder than I thought it would be.
Anyways, SharpEdge is right, I don’t need to know which tile has been clicked, I just need to be able to click on the plane and a popup window should ask to select two bitmaps and then tile them across that one plane.
Can a bitmap be tiled with normal maps also?

[Embed(source="assets/a.jpg")]
private var bitA:Class;
[Embed(source="assets/b.jpg")]
private var bitB:Class;
...
var sA:Sprite=new Sprite()
var sB:Sprite=new Sprite()
var sC:Sprite=new Sprite()
var sD:Sprite=new Sprite()
sA.addChild(new bitA())
sB.addChild(new bitB())
sC.addChild(new bitB())
sD.addChild(new bitA())
var ss:Sprite=new Sprite()
ss.addChild(sA)
ss.addChild(sB)
ss.addChild(sC)
ss.addChild(sD)
sB.x=sD.x=128
sC.y=sD.y=128
addChild(ss)
var bmp:BitmapData=new BitmapData(ss.width,ss.height,false,0)
bmp.draw(ss)
_plane = new Mesh(new PlaneGeometry(700, 700), new TextureMaterial(Cast.bitmapTexture(bmp)));
...
I post this,I think if someone posted a way(perhaps it’s not so good).Maybe you can try yourself to find more better way to do what you want.
Don’t be waiting for an answer,open you mind,just do it *^_^*

Other way, assuming your images are of correct size (in this case 512x512), otherwise you should also apply a scaling.
NOT TESTED, this is jut to give an idea of what i mean:
public static const SIZE : int 1024;
public var img1 : Bitmap;
public var img2 : Bitmap;
var bmp:BitmapData=new BitmapData(SIZE,SIZE,false,0);
bmp.draw(img1);
bmp.draw(img2, new Matrix(1,0,0,1, SIZE/2, 0));
bmp.draw(img1, new Matrix(1,0,0,1, SIZE/2, SIZE/2));
bmp.draw(img2, new Matrix(1,0,0,1, 0, SIZE/2));
