1  Questions & Help / X3D / Re: AOPT Tool - Documentation on: June 05, 2016, 06:45:23 am
I know I'm just replying to myself here, but I have solved this issue for myself.
I have been using the documentation located here:
http://doc.x3dom.org/tutorials/models/aopt/index.html

I copied and pasted the example arguments into the command line.
Do not do ths! - for some strange reason the first minus sign in all
the arguments is the wrong unicode character, although it LOOKS like a minus sign.

If you copy and paste from the docs it will look fine, but AOPT will see THIS:
Command Line: aopt i myFile.foo -x myResult.x3d
When what you want is THIS
Command Line: aopt - myFile.foo -x myResult.x3d

To answer Alberto's original query these Docs at x3dom.org cover conversion to binary geometry - just don't be stupid like I was and copy and paste from them!

Hi - I am still trying to use AOPT.
I have read everything I can find in terms of documentation.

Here is an example of an argument I am trying to send to AOPT:
aopt i example.obj -x myResult.x3d

I always get the following error:
FATAL   Avalon
Malformed arguments.

I have tried using a .ply instead of a .obj
I have checked the input geometry is perfect and to spec
I have tried AOPT on windows7 32bit OS
I have tried AOPT on windows7 64bit OS
I have tried the latest versions and old versions of AOPT
I have tried running the command line as Administrator
I have tried including a direct path to the input file in quotes,
I always get the same fatal error

Has anyone on this forum got AOPT to work?
If you have can you tell us what your platform and setup is?

Thanks!!!

3  Dailybuild Feedback / InstantReality 2.8 / Can't use AOPT - "License has no 'hub/aopt' feature!" on: February 26, 2016, 05:40:12 am
Hi, I'm trying to use AOPT to convert meshes for use in x3dom.

I'm getting the following error when running AOPT at the command line:

License has no 'hub/aopt' feature!
WARNING Avalon   Unable to acquire license for feature hub/aopt

I can't find any info on this website on where to buy / obtain a license,
how much it is etc...

Any help greatly appreciated

Bump!
Can anyone tell me how they learned to use this stuff?

I've been trying to read loads of books on opengl / webgl / glsl,
but I could do with some pointers Smiley
5  Dailybuild Feedback / InstantExport (3D Studio Max) / Best Practice for x3dom export on: February 26, 2016, 03:22:36 am
Hi - I'm trying to use Instant Reality export to export a model to use in x3dom

This x3dom example uses binary geometry.
http://www.x3dom.org/x3dom/example/CSShader-ObjectSpace/

I hope to use Instant Reality to export a mesh with all the same features:
This means I need to export the following files:

foo_.xhtml
foo_indexBinary.bin
foo_coordBinary.bin+8
foo_normalBinary.bin+4
foo_texCoordBinary.bin+4

Does anyone know the all the correct settings for Instant Reality
in order to get this output? I have managed to reproduce this file structure, but without the +8 and +4 suffixes, and I can't get the model
to be recognised in x3dom.

I don't know what the +8 and +4 suffixes mean.

Also are there any rules for the source mesh?

Thanks for any tips - and if there's a manual for this plugin,
or a tutorial,  let me know!
