hello,
would you guys give this a try.
the test.ae file in data folder is a copy from AE with hand made frame data for position, scale, rotation, anchor.

so far it parses general info and object pos/scale/rot/anchor data (3d components and all componets are together) but should be easy to add more fields/parameters.

you should see your data be printed in the console.

i would like your feedback on your own scene imports to see if it works ok

cheers,

ok, that is good.
those numbers are a print of the current line being parsed. its a forgotten println.

ill implement lights and cameras. if you have any suggestions, shoot

How are you planning the processing features?
Like how to use them?

for now i'm just planning multiple text files and using the copy&paste method per object.

I'm working on the importer from AE so it will be able to load data from AE correctly, anything that really matters.
Later on i should write an exporter, which will export data from your application so you can use it with AE.

I hope to be able to export data from applications based on data retrieve from opengl, so i have no plans on supporting 2d or p3d modes. Later on if this gets interesting someone else will do it eventually.

Anyway, any object you want to export, might need to be attached to some listener/class that will tell the exporter it is exportable. So, based on the exporting method the textfile will be created. It might also need a start-end time aswell, so you can control the exporting data.
This is just an idea WIP, i'm not sure if it will the way to go or not. It's not a priority right now.

What's in your mind?

in my mind if the resultion of the processing sketch is 900 x 900 and the same is in AE then when a image or a object get's futher away in the z depth then how far it is must look equal in AE. I got more in mind but without that it would be fail. This will also depands on the camra angle, so maybe there must be a way to define a camera in processing where the keyframes can be copied to AE. This can be quite tricky and if you need help with fihure out values i meight can help but i don;t know if i have the skills to suceed.

I hope atleast that you understand what i mean.

If i put what i mean in a big contrast then i would say that the perspective way you look at things in AE shouldn't look in a orbit way in processing.

After that it would be cool if the light values come close ot the AE values.

btw when you create a output then you can declare

output.println("something");

for example.

I don't know if it's possible but maybe something can be used like:

object1.translate(10, 200, 50);
object1.rotateX(50);

etc.

where in the end all values of object1 can be exported to a AE file.

object1 could be a point, box, image etc.

i sure would like your help for one thing.
3 textfiles that define some animation of 3 things:
a camera, a light and an object.

i've been messing around with AE but haven't got to that, so i would appreciate some nice examples so i can reproduce the same within an application.

yes transformations between spaces is something to care about, i'm aware of that. an AE camera and a camera in processing is not the same. diff space.

let me know if you can get me that example. would be nice

I second your request on those examples. Would be helpful. Messing around with AE myself, but feel like I'm going at it blind a bit.

some changes in values make no sence does that matter?
Like with the light, it's like rotating a black circle, you can't see that it rotates.
Also i took a bit more then a minute now to see if that would get you into troubles, if you want more then a hour or something then tell me.

p.s. a parrent function would be sweet.

Hey Clan,
thanks for the data files but there is one problem. The transformations your sent are splitted by component. I believe putting them together is a much sweeter option, and also because i do not have support for splitted method.

so instead of

Transform X Rotation
Frame
Transform Y Rotation
Frame

it should come as what i believe is to be correct:

Transform Rotation
Frame  Degrees X Pixels  Y Pixels Z Pixels


same goes for position and scale, etc.

As for the text files, placing them in a post is not going to work. I take the TAB spaces into account, so the importer won't work without them. FIXME!!
can you upload it somewhere, with the new changes ??

lets swap emails, working thru a forum is just weird
