I guess we should really turn the driving autoreply thing off. It
really looks like a spam. Especially when nobody's asking questions.

Zachary,

you can build OpenSceneGraph into static libraries yourself.
Just get yourself comfortable with OpenSceneGraph first, in the way it
is distributed by MSYS2.

Michael.

sure OSG will run on Windows. Just make sure to distribute all
necessary DLLs along with your EXE.
You can find those DLLs with dependency walker: http://www.dependencywalker.com/

you can use VirtualBox to run Linux VM as guest.
Once you get comfortable with OSG, you can move to Windows host yourself.

I can give you a Linux VM for VirtualBox with OpenSceneGraph built

Re: [osg-users] EditorConfig file?

[michael kapelko]

Hi, Chris.

I would guess it might be not exactly appropriate to update
OpenSceneGraph sources just to have the order in spaces and tabs.
However, I think VulkanSceneGraph would definitely benefit
EditorConfig rules. So once VSG has its place at GitHub, I would
recommend re-raising this issue and creating a pull request.

Regards,
Michael.

Hi, Chris,

just create EditorConfig and share it. Those who are interested will
follow you.Don't wait for us to want your thing. Just do the thing,
show it and explain its benefits.
You're not alone, we're here, but you lead EditorConfig initiative, not us.

Re: [osg-users] Help about obtaining a particular OSG build.

[michael kapelko]

Here are some details that you probably miss, A Z / Zachary:

1. Nobody is using TDM here, so nobody can tell you what to do
2. We are here to help
3. Help means you lead the way, and we help you do that
4. Staying on the 'just gimme the build' side means that's a trade, not a help
5. If that's a trade, you have to explicitely tell you want someone's
skills (build TDM) in return of valuable resource (money)

Thus, you can lead by sharing build logs, source code, video of your
trials, and only then can we help.
Or simply ask someone to spend their time on your issues and
compensate that time.

Although, I think osg-users group would be able to celebrate the first
anniversary of you asking the same question for a year if you keep on
doing like that. THAT would be funny.

Re: [osg-users] How do I continuously read the mouse position as the mouse is moving, without a click event in osg

[michael kapelko]

Hi.

Not sure why you "read" it during FRAME events. I personally create a
class that:
* inherits osgGA::GUIEventHandler
* overrides its bool handle(const osgGA::GUIEventAdapter
, osgGA::GUIActionAdapter , osg::Object
*object, osg::NodeVisitor *visitor) method

bool handle(...) method is where you get notified of mouse events once
you subscribe that class of yours to osg::Viewer events by using
osg::Viewer's addEventHandler(...) method

For example, here's my Mouse class:
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/master/05.NodeSelection/desktop/src/input.h#L84

A better approach is to share your Git/Mercurial repository with us
and ask questions like 'I did X on line Y, but Z is not doing W". Then
there's a chance someone here can help.

Re: [osg-users] Question about security of shader developments

[michael kapelko]

Hi.

You may have a look at the problem from a different angle. If someone
is stealing from you that means they need it. If you cannot stop it
(or it costs much more than simply let them have it), then you should
lead it. Instead of hiding your great shaders you can publish them
yourself (don't forget to add some notes about your company in the
comments)! This would be the marketing way of handling the problem.

Re: [osg-users] WxWidgets Examples?

You might have a better luck in understanding how OSG works with WX by
first trying osgQt examples. I know this takes longer, but at least
osgQt is known to work.

Re: [osg-users] Two basic OSG use Questions.

[michael kapelko]

Hi.

I personally think you should describe the final goal you want to
achieve with OSG and WX, and then it'll be a lot easier for us to help
you.

As for texture mapping, you should assign osg::StateSet to your
osg::Shape (or its parent osg::Node) and then use that osg::StateSet
data in your fragment shader. osg::StateSet should hold a texture.

Re: [osg-users] General Users starting questions in OSG 3.0, 3.5

[michael kapelko]

Hi.

> 1. Is it always possible to avoid using Shaders, in OSG programming, to 
> acheive any particular task?
You can use fixed function pipeline only on desktops, this restriction
comes from driver manufacturers. If you're fine with desktops only,
OSG can do without shaders.

> 2. Is it always possible to avoid using OSG Macros, in order to acheive
any particular task?
Which macros exactly? If you refer to META_* macros, those are only
necessary if you want to modify OSG itself or if you want to create an
easy-to-use OSG nodekit like osgEarth: http://osgearth.org/
If you simply use OSG to render things for you, you don't need OSG
macros in your own code.

I've read the book a few years ago, so can't remember that part. It
would be great if you could clarify the question.

If you want to add a shape into OSG scene, then here's how to create
an osg::MatrixTransform that you can add to osg::Group or pass to
osg::Viewer::setSceneData():
* 
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/master/features/scene/createShape.cpp

A code snipper would help, since I don't have the book around me.

Re: [osg-users] Question about obtaining built .dlls.

Hi.

Have a look at detailed instructions on how to build OpenSceneGraph
for Windows with MinGW here:
https://github.com/OGStudio/openscenegraph-cross-platform-guide/tree/master/1.3.InstallUnderWindows

And here's a sample OSG application that fits into a couple of files
(and is also built for Windows):

Re: [osg-users] [ANN] Cross-platform examples for Linux, macOS, Windows, Android, iOS, and Web

[michael kapelko]

Hi, Robert.

I agree with you that explicit usage of `this` is not something I see
frequently myself. That's a valid point. I've been on that side, too.
Probably, because I never asked myself about `this`.

My work is related to iOS development, so I've seen Apple ecosystem
migration from Objective-C to Swift. Objective-C requires `self` (aka
`this`), however, Swift does not. There have been debates about `self`
in Swift, too: https://github.com/raywenderlich/swift-style-guide/issues/7
This migration is what made me wonder if using `this` in C++ and
`self` in Swift has benefits.

I'd like to bring a few more thoughts why `this` is better than `_`,
`m`, or `m_`:
* altering variable names to reflect environment (member / local)
always seemed inappropriate to me
* `_`, `m`, or `m_` is really just a shortcut for using `this`

So, since everybody else was already distinguishing local variables
from memeber ones with some sort of Hungarian notation, I just tried
to be honest and use facilities provided by the language itself:
`this` pointer.
In case I find a serious drawback that would cost me hours of
development time, I would definitely go back to `this`less approach.
But so far I've seen no problem with `this` approach.

Re: [osg-users] [ANN] Cross-platform examples for Linux, macOS, Windows, Android, iOS, and Web

[michael kapelko]

Hi, Robert.

I started to use explicit `this` to simplify reading and increase
"shareability" of code:
* I don't need to rely on IDE to highlight member or local
variables/functions for me, so I can get away with simpler and faster
tools (VIM, in my case)
* I can paste such code blocks anywhere, and a reader won't need to
run IDE to know this is member or local variable/function/etc.

So far this approach looks better to me. When I see code referencing
member variables/functions without `this`, I need to know what
particular color IDE uses to tell member/local variables apart. And to
make things more complicated, different IDEs use different colors :)

[osg-users] How I build OpenSceneGraph manually for desktop, mobile, and web

[michael kapelko]

Hi.

Recently I've started building OpenSceneGraph without using official
CMakeLists.txt file. I've decided to describe why and how of this
process.

1. WHY.

I use OpenSceneGraph to develop cross-platform applications. While
desktop builds work mostly fine, anything else (Android, iOS, Web) is
easy to break and hard to fix.

Here's my list of top annoying things I had to deal with frequently:

1.1. Inability to build Lua plugin out of the box on macOS

My project's CMakeLists.txt uses `ADD_DEFINITIONS("-std=c++11")` to
force C++11. This breaks Lua plugin building on macOS because Clang
says C language does not have `C++11`, which makes sense. However,
Linux's GCC simply warns about it.

1.2. Hacking PNG plugin safety checks for Android

To build OpenSceneGraph's PNG plugin for Android, I need to hack
CMake's PNG plugin detection because OpenSceneGraph's CMakeLists.txt
uses standard `FIND_PNG`. While this works fine on desktops, Android
sucks at supporting STL, exceptions, and other standard stuff in old
APIs. I personally target API 14.

1.3. Maintaining two different builds for iOS - simulator and device

You have to configure and work with two different versions of the same
application for both simulator and device. Which means you can't
switch between device and simulator in the single project. Not to
mention how many hacks went into OpenSceneGraph's CMakeLists.txt to
support iOS.

1.4. Building OpenSceneGraph takes A LOT of time

Even firing 10 parallel build processes with 'make -j10' is damn slow
because OpenSceneGraph has a ton of files.

2. HOW.

2.1. Build OpenSceneGraph as part of the project into static library

Here's CMakeLists.txt I currently use for all platforms except iOS:
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/c42fcbaaf4064b0853246e68837bc91d2b1842c9/libs/OpenSceneGraph/CMakeLists.txt

2.2. Build OpenSceneGraph libraries from custom source files

Custom source files include OpenSceneGraph source files directly.
Here's how osgGA.cpp looks like:
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/c42fcbaaf4064b0853246e68837bc91d2b1842c9/libs/OpenSceneGraph/src/osgGA.cpp

This allows to build OpenSceneGraph multitudes time faster at the
expense of using more RAM during building.
As for plugins, I no longer need to hack my way through plugin
dependencies' safety checks, I simply include necessary source files.

2.3. Prepare OpenSceneGraph header files for each platform in advance

OpenSceneGraph and OpenThreads require different headers (osg/GL,
osg/Version, osg/Config, etc.) for different platforms and (probably)
compilers. I simply generated those headers by configuring stub
projects.

2.4. Build OpenSceneGraph as part of iOS project without CMakeLists.txt

Wrap all C++ files (.cpp extension) into Objective-C++ files (.mm
extension) and include them into Xcode project. Now you can switch
between simulator and device just like in other iOS projects.

3. EXAMPLE

OpenSceneGraph cross-platform examples now use described approach.
Check out how easy it is to build them for desktop, mobile, and web
platforms: https://github.com/OGStudio/openscenegraph-cross-platform-examples

Re: [osg-users] Load an obj file and mapping a given vertex to its Texture coordinates

[michael kapelko]

Here's how I change texture coordinates:
https://github.com/OGStudio/ogs-mahjong-components/blob/0308cd2ed97b001cf5aecea1b5aada839707c5cf/02.Theme/desktop/src/render.h#L184
Note that the function gets osg::Geode that has already been extracted
from osg::Node.

Here's a sample class to print whole osg::Node structure (replace
log::logprintf with printf):
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/f692fd8b0886dbdba1d4e99087998e87827056db/features/scene/PrintGraphVisitor.cpp
You need to create this class instance and call
'yourNode.accept(instance);' to have the structure printed.

Re: [osg-users] [forum] Android can't build osgdb_png

[michael kapelko]

Hi.

I've detailed building PNG under Android a few months ago in this
example: 
https://github.com/OGStudio/openscenegraph-cross-platform-examples/tree/master/02.TextureImage#android

Basically, you need libpng-android and a few CMake tweaks.

PS: Björn thanks for sharing :)

Hi.

Any particular reason for running the whole day? (Was that requirement
somewhere in Vulkan end-user agreement? :P)

Re: [osg-users] Announcement: VulkanSceneGraph and SceneGraphTestBed!

[michael kapelko]

Since we're talking about standard proposals now, here are some I would want:

1. Provide an option of single header and source file per each module:
vsg.h/cpp, vsgViewer.h/cpp, vsgUtil.h/cpp, etc.

This would greatly simplify referencing VSG across platforms because
CMake has issues under Android (it's part of Android Studio project,
so CMake does not drive building) and iOS (one can build a library
with CMake to be referenced by Xcode project).
So, simple header/source inclusion still wins distribution battle when
you target desktop, mobile, and web at the same time.

2. Conform to `Best Practices Criteria for Free/Libre and Open Source
Software (FLOSS)`
The rules: 
https://github.com/coreinfrastructure/best-practices-badge/blob/master/doc/criteria.md
Here's how a conforming project looks like:
https://bestpractices.coreinfrastructure.org/ru/projects/289

John (aka MT), make sure you use VBO
(osg::Geometry::setUseVertexBufferObjects) on your geometry if you're
rendering with GLES.

Re: [osg-users] Announcement: VulkanSceneGraph and SceneGraphTestBed!

[michael kapelko]

Hi. Great news!

1. Target C++20: by the end of 2030, when (supposedly) all new
graphics software uses Vulkan, C++20 will be old enough
2. My personal concern is the ability to run VSG on linux, windows,
mac, ios, android, and web browsers, so I volunteer to help in testing
closs-platformness of VSG.

Re: [osg-users] OpenSceneGraph-3.6.0 stable release is tagged!

[michael kapelko]

Hi.

I know I'm late to the party, however, I'd like to note that 3.6.0
version broke public API for iOS.
osgViewer::GraphicsWindowIOS::WindowData constructor has been updated
by injecting an optional parameter in the middle of constructor
argument list.
This broke my iOS builds. No kudos for the contributor who did it.

This note is just a reminder for everyone to keep public API stable.

Re: [osg-users] [osgPlugins] No specular maps, exporting from blender or converting using osgconv

[michael kapelko]

Hi.
Since specular map is a texture, you would generally manage texture
application through shaders and osg::Program.
Blender doesn't and can't export shaders because each shader is
application specific: Blender shaders are different from
OpenSceneGraph ones.

So, you need to manage specular map in your own shaders.

[osg-users] [ANN] Cross-platform examples for Linux, macOS, Windows, Android, iOS, and Web

[michael kapelko]

Hi.

TL;DR
All hail the first cross-platform example on how to embed a binary
resource into executable:
https://github.com/OGStudio/openscenegraph-cross-platform-examples/blob/master/01.EmbedResource/README.md

Lengthy explanation.

Once the OpenSceneGraph cross-platform guide (
https://ogstudio.github.io/openscenegraph-cross-platform-guide/ ) has
been finished, I started developing a cross-platform game (
https://ogstudio.github.io/game-mahjong/ ).

Overtime I started to face different issues across platforms like
loading resources, loading images, etc.. It became clear that I should
share this knowledge. That's how cross-platform examples appeared:
https://github.com/OGStudio/openscenegraph-cross-platform-examples

Unlike the guide, examples are brief, don't provide videos and
screenshots for each step. Instead, each example focuses on the
crucial code necessary to perform a task.

I would be glad to hear of any specific thing you wanted explained for
OpenSceneGraph that might make a good addition to the examples.

builds: https://github.com/openscenegraph/OpenSceneGraph/pull/501

The mentioned changes break rendering of the osgemscripten example
(found in OpenSceneGraph/examples/osgemscripten).
I've prepared two builds to depict the difference.
1. Build with the breaking fix:
https://kornerr.github.io/osg-pbo-gles2-fix-builds/versions/fix/osgemscripten.html
2. Build with the breaking fix reverted:
https://kornerr.github.io/osg-pbo-gles2-fix-builds/versions/reverted-fix/osgemscripten.html

The second build simply has the following GLExtension.cpp line:
  isBufferObjectSupported = isVBOSupported && isPBOSupported;
replaced with:
  isBufferObjectSupported = isVBOSupported;

So the problem is not really in PBO support, but in the fact that
possibly missing PBO support removes buffer object support. This is
wrong. The osgemscripten example uses VBO and this is what WebGL1
requires.

You can build osgemscripten example yourself (README explains how to
do it, it's easy on Linux) and see the errors.
Make sure to use the updated CMakeLists.txt I've attached to this email.

Re: [osg-users] OpenSceneGraph-3.6 branch made, please test in prep for stable 3.6.0 release

[michael kapelko]

Hi.

The "GLExtension fix" PR (
https://github.com/openscenegraph/OpenSceneGraph/pull/485 ) broke web
builds ( 
https://github.com/OGStudio/openscenegraph-cross-platform-guide/tree/master/1.10.SampleWeb
).
Moreover:
* neither "GLExtension fix" PR, nor osg-users mailing list contained
ANY description
* the change was INCONSISTENT because the checks before and after it
were still using the removed GLES2_FEATURES

I've created the PR (
https://github.com/openscenegraph/OpenSceneGraph/pull/501 ) to restore
PBO for GLES2.

Hi.
I think the community (including me) is currently in the 'get it done
and we'll use it' mode. So do it whatever way you like, then everybody
will be eager to test and use it.

Re: [osg-users] Conan C++ dependency manager

[michael kapelko]

Julien, don't forget to include step by step guide(s) on how to build
OpenSceneGraph for Linux, macOS, and Windows once you're done with the
first iteration.
I'm sure other people would try Conan then, too.

Re: [osg-users] Conan C++ dependency manager

[michael kapelko]

Hi.
May be introduce some sort of subdirectory (like
osg_src/packaging/conan) into the main OSG source tree as a pull
request?
Having separate repository doesn't seem correct.

Depends on how you build for Android.
Here's how to build OpenSceneGraph application with Android Studio:

Re: [osg-users] Call for assistance: Migrating and updating tutorials

[michael kapelko]

Hi.
I can't see any tutorial. It's just a Table Of Contents. I guess at
least one tutorial is necessary to evaluate navigation.

As a side note, https://readthedocs.org/ hosts lots of docs with a
nice navigation, so this might be an option.

[osg-users] How to work with zip archives?

[michael kapelko]

Hi.
Can anyone provide example on how to work with zip archives? I see
there is a zip plugin but I can't find any example with it.

I want to read my zips from memory because I do not read them from
disk, I have them built into the application.

Any clues?
Thanks.

[osg-users] "Memory: Colors" game from scratch

[michael kapelko]

Hi.

You may remember that some time earlier this year I've posted about
OpenSceneGraph cross-platform guide (
https://github.com/OGStudio/openscenegraph-cross-platform-guide ) that
describes how to render a simple cube on desktop, mobile, and web.

Once that was over, I headed straight to creating the first
cross-platform game with OpenSceneGraph. This gave birth to MJIN
project ( https://bitbucket.org/ogstudio/mjin ), which builds on
OpenSceneGraph.

I have successfully built the game based on Memory board game.
Here's web version:
https://ogstudio.github.io/game-memory-colors/0.3/mjin-player.html
Note the famous OpenSceneGraph background :)

Once the game was done I decided to describe how to create it from scratch.
I've just finished the third article. All articles are in the game's
home repository:
https://bitbucket.org/ogstudio-games/memory-colors

If you wanted to create a simple game for a long time but did not know
where to start, now is a good chance.

Thanks.

[osg-users] How to pre-compile shaders before actual usage?

[michael kapelko]

Hi.

I want to pre-compile shader programs before they are actually used by
real nodes.
I tried to create empty node (new osg::Node) and assign an
osg::StateSet with an osg::Program, but such action did not trigger
shader compilation.
In the logs I see shader compilation happening only when I assign
osg::StateSet to actual nodes at my screen.

What am I missing?

Re: [osg-users] Only 1 Tutorial On OSG Website

[michael kapelko]

Hi.

If you want information for beginners, I recommend OpenSceneGraph
Beginners Guide book (
http://www.openscenegraph.org/index.php/documentation/books/10-openscenegraph-beginners-guide-published
), it's simply the best source to understand OpenSceneGraph concepts
and see tutorials.

If you are interested in a specific rendering technology, you should
consult examples/ directory in OpenSceneGraph sources.

If you are interested in cross-platform development, take a look at
the cross-platform guide:
https://github.com/OGStudio/openscenegraph-cross-platform-guide

Thanks, Jannik.
I used your suggestion in the tutorial (

[michael kapelko]

Hi.

TL;DR Sample OpenSceneGraph application in Web:
https://ogstudio.github.io/openscenegraph-cross-platform-guide/
Give it a try!

-- Official --

I've finished my work on the OpenSceneGraph cross-platform guide:
https://github.com/OGStudio/openscenegraph-cross-platform-guide

It contains step-by-step instructions with screenshots how to build
and run sample OpenSceneGraph application under the following
platforms:
* Linux
* macOS
* Windows
* Android
* iOS
* Web

It also contains YouTube and downloadable (MP4) videos depicting every step.

I hope this guide fills the gap of good cross-platform documentation
for OpenSceneGraph.
I plan to maintain it and update whenever something changes in the
build process. Drop me a line if anything becomes outdated and/or I
have missed it.

-- Personal --

Last year once I got the first taste of my own game editor results (
opengamestudio.org ), I realized supporting only desktop in 2017 is a
no-go. So I started to research Android support.
Since OpenSceneGraph Android samples are of pre-AndroidStudio era and
I was a newbie in Android native development, I spent literally
several months trying to get OpenSceneGraph render under Android.
Then came iOS and Web, which were just a piece of cake, compared to Android.
I realized that there may be many people who waste as many months just
to get OpenSceneGraph to mobile and web. That's why I decided to share
the knowledge in the form of detailed tutorials with screenshots and
videos of the whole process.

I hope this saves you precious time!

Re: [osg-users] Fwd: Strange osgShadow appearance of multiple models self-shadowing under a point light

[michael kapelko]

Hi.
I can't say anything about your specific problems, but I had wrong shadows
when small objects were outside larget objects, i.e. if there's a plane and
a ball, and ball is outside the plane, the shadows were sometimes wrong.
To test my assumption, you can add a model with a plane that is underneath
*everything* in the scene and a wall that is heigher than *everything* in
the scene.

Re: [osg-users] Investigating using OSG as a graphics backend for our real-time physics simulation system

[michael kapelko]

Hi.

* Cross-platform support. In short, OpenSceneGraph runs everywhere
with only a bit of configuration. I currently work on the
cross-platform guide for OpenSceneGraph to cover major platforms:
https://github.com/OGStudio/openscenegraph-cross-platform-guide

* Embedding. OSG-Qt integration works on all desktops (I have not
checked other platforms).

* Back-end. There are rumors that Vulkan driven scene graph may appear
in the future.

* OpenGL deprecation. Apple is actively pushing Swift, but Swift still
has no stable ABI and most of Apple's own software is still in
Objective-C. I'm sure OpenGL is here to stay for at least a decade.

Re: [osg-users] A problem with regard to std:istream on Android

[michael kapelko]

Hi.

Are you sure /sdcard path is valid at all? Different Android versions
use different sdcard paths. Use getExternalStorageDirectory():
https://stackoverflow.com/a/21230946/3404710
Note that you need a special permission to read from external storage, too.

Re: [osg-users] [build] Building OSG for Android -- Windowing system issue

Hi.

I've just published Android tutorial:
https://github.com/OGStudio/openscenegraph-cross-platform-guide/tree/master/1.8.SampleUnderAndroid

If you have any questions or ideas, I'd be glad to hear from you.

Re: [osg-users] [build] Building OSG for Android -- Windowing system issue

[michael kapelko]

Hi.
I tried to use android.toolchain.cmake, too, but that requires
configuration and building outside AndroidStudio. I ended up simply
including OSG as 'add_subdirectory' into native-lib's CMakeLists.txt that
AndroidStudio creates. That way, OSG is built as a dependency whenever
native-lib is built. Such approach removes the need for doing anything
outside AndroidStudio, referencing external toolchain file, and you get OSG
built for those ABIs that you specified in 'abiFilters'.

I plan to publish Android tutorial with the mentioned approach next week.

It would be great to have at least some project that one could run in VS.

Re: [osg-users] [build] Building OSG for Android -- Windowing system issue

[michael kapelko]

Hi.

I'm currently working on a set of tutorials for OSG:
https://github.com/OGStudio/openscenegraph-cross-platform-guide
I've just finished re-doing Android support for sample application:
https://github.com/OGStudio/openscenegraph-cross-platform-guide-application

The tutorial for Android is in the process, but if you're interested to do
it yourself, here's the Android-only part for the sample application:
https://bitbucket.org/kornerr/android-osg-tutorial (You can open it in
AndroidStudio)
Its CMakeLists.txt builds OpenSceneGraph as a static library. It also
builds android-static-lib, but you can safely remove it, since this was
just a test.

The crucial CMake OSG options are in build.gradle file:
https://bitbucket.org/kornerr/android-osg-tutorial/src/tip/app/build.gradle?at=default=file-view-default

I plan to finish the tutorial in a week or two, so you may want to revisit
the guide later for a complete Android tutorial.

Hi.
Will this pull request include an example? Does it work on Windows Phone?

Hi, Alberto.

This seems like a valid path, but I'm not yet sure how to insert it into
do-it-yourself series. I'll give it a thought.

Thanks.
