    Thank you, This is really great!

    This is what I need.

    But I have some questions …

    Why I will provide you with the source code is read after the execution can not sign it?

    In the code I do not see camera_para.dat, in this example is not to be need?

  2. ericsoco says:

    hi tarotaro. thanks for posting this.
    what branch of FLARToolkit does this example use? does this use alchemy?

  3. tarotarorg says:

    Hi, ericsoco.

    This example uses FLARToolKit ver1.0.0.

    Thank you.

  4. afish says:

  5. tarotarorg says:

    Hi, afish.

    What is “project”, do you mean?
    You say about Flash builder project?

    I don’t have project file because I don’t use Flash builder.

    Thank you.

  8. tarotarorg says:

    Hi, gabscung .

    Can you compile build and execute this code?
    This code doesn’t need camera_para.dat.

    Something may be wrong in your project.
    For example, FLARTK version .
    Please review it.

    Thank you.

    -1067: Implicit conversion from a value of type Array to a type _AS3_: vec: Vector. Unrelated. I could tell that it should?

    Your compiler version may be old.
    Please try to compile using latest Flex SDK.

    Thank you.

    Taro:

    Thank you very much for the code… it worked well for me. Do you know if it’s possible to make the multi-marker test work with FlarToolKit 4.0? I am trying to make it as fast as possible.

    Thanks again,

    -Gabriel
