BtOgre21, forked for Ogre 2.1 that uses Item. + debug drawer

Ybalrid · Post by **Ybalrid** » Mon Apr 17, 2017 1:56 am

Edit : You can download the 1.2.144 Release from there if you don't want to use Git https://github.com/Ybalrid/BtOgre21/releases/

I had a bit of time, and I was playing around with Ogre 2.1 (porting my pet project to it, a game engine for VR, Rift and Vive that uses Ogre and a bunch of other cool open sources libraries)...

So I present you my fork of btOgre, that can take Ogre v2 Items and Meshes as input (thus, not relying on having v1 objects around) and with a debug drawer that support all the "configurations" you can ask Bullet to draw debuging for (you know, contact points, AABBs, changing the colors depending on activation states, all that good stuff )

https://github.com/Ybalrid/BtOgre21 There's a release tagged 1.2.144 that you can grab.

The idea comes from personal needs, and the fork originally made by nyxkn that added an overload to take v1::Mesh and not just Entities (along side adding the v1 namespace everywhere so that the library will build), but with a few other changes.) I did not want to keep v1 meshes around just to generate their physics representation in my own projects... ^^"

The C style array manually reallocated every time in the extraction of vertex and index buffers (and all the pointer arithmetic that comes with reading them back) have been replaced by std::vectors, because it makes the code easier to read, (and I like the STL containers, and vectors are basically flat raw arrays ^^"). I'm not using push/emplace back, but resizing the array by hand with the known size to make, so it's virtually the same thing.

Changes made from the original version of btOgre

Code: Select all
```
[*]Modified to compile against Ogre 2.1
[*]Added an overload to construct a static shape converter from an Ogre::v1::MeshPtr
[*]Motion states moves "derivated coordinates" instead of the "regular" ones. This prevent unsynchronising graphics and physics if you are doing weird object parenting stuff (in case of physics objects, You probably shouldn't)
[*]The static mesh to shape converter has overloads to use v2 meshes and Items, instead of just v1 meshes or Entity object
[*]Class implementation are not in headers
[*]Debug drawer re-implemented for Ogre V2 by using a v2 manual object
[list]
    [*]The debug drawer now supports every mode of debug drawing Bullet can offer, and does it with the proper colors
    [*]The debug drawer uses an HLMS Unlit datablock created at run time the first time you call it, and set vertex colors on each points of each lines
    [*]The color of the line is multiplied by a factor the user can set to accomodate HDR rendering pipeline and the way the user wants to deal with color spaces and gamma correction
[/list][/list]
```
It's under the same zlib license, uses CMake, is installable, and shipped with a "FindBtOgre21" cmake modules that makes it easy to configure for your own projects.

The project on the "demo" subfolder "works", but that's about it. The PBS materials are broken, I'm not using the original framework, I just hacked it together to run. It uses the original .mesh files, but convert them at runtime to v2 objects the same way the samples does. and is only OpenGL because I copy pasted code from a linux only project and it's looking for the "GLSL" subfolder of the HLMS library. I'm going to fix theses things...

I hope this can be useful to other people in the Ogre comunity, I did not touch the AnimatedMeshToShapeConverter yet, since I'm still not familiar on how the animations are dealt with in Ogre 2 (the v1 and v2 systems seems to coexist since as far as I have read on the documentation, v2 is good for playback of pre-made ones, v1 is better when moving stuff "live" ). I'm also interested on soft body physics, so I'll probably work on that next.

Any thoughts and comments are appreciated, specifically if you fond problems with it, don't hesitate to submit issues and pull request!

Awesome, kudos.

So, I took some time to put this online : http://btogre21.ybalrid.info/api/annotated.html (will add this link to the 1st post)

All the methods of all classes are annotated here, except for the AnimatedMeshToShapeConverter, that is still using the old v1 code for now (I haven't looked at it too much yet.)

What's more interesting to support next, getting the Animated Meshes to work with v2 Ogre::Item, or some other thing?

Thank you very much for updating this wrapper. Great job.

Thanks areay. If you encounter any problem or have any suggestion, please share them here or on GitHub.

I still did not took the time to look into the "animated mesh" part. I never actually used that code on the original library either. Looks like it tries to fit a rigidbody around each bone of the skeleton attached to the object. ^^"

Absolutely amazing stuff! I was just looking around for some bullet wrappers to use for my Ogre based game since I wanted to add some better quality physics and this is exactly the stuff that I needed. Great job and thanks for this! Amazing times in open source. Ogre3D for rendering, bullet for physics, add an audio framework and SDL2 and you have a game engine

. Take that Unreal and Unity! (I'm just joking I have nothing against Unreal Engine nor against Unity).

Just wanted to say thank you for doing this, it does lower the bar for others who are not able to spend the time \ effort do such a integration.
I have not tested it yet - but my plan was to do this exact thing - use bullet with latest Ogre.

I did integrate bullet into 3dsmax some time ago, I learned a lot from there, I especially enjoyed the softbody physics.
Is the softbody physics integrated here as well?
When I get started with my project I'll see if i can help out with some things.

Hi,

This is a fork of an old little tool that used to work with Ogre 1.x. The original library had no support for softbodies at all.
Currently, this one doesn't either, but I want to add it, but I never actually used softbodies with bullet personally so I'll need to do some research and experimentation with it before starting to actually work on this.

Obviously, any kind of help is appreciated

hedphelym · Post by **hedphelym** » Thu Jul 13, 2017 9:16 am

It works with trimesh data, (so you read the vertices out of your ogre mesh), create the softbody in bullet, send in the vertex data, apply softbody properties, trigger simulation,
you then fetch the vertex position from bullet (you get it in world space) and apply it to your ogre mesh.
That's the basic steps for it. I have lot's of code related to this (but as I mentioned - it's for 3dsmax, but the bullet code is generic and can be applied anywhere).

I will take a look at your code and such tonight and tomorrow.
I currently work exclusively on Linux, so I hope to get everything up and running fine there.

I see; seems doable without "too much work". Just has from that I just have to figure out how to modify vertex position in Ogre's "vertex array objects"... This is apparently done asynchronously by communicating with (well, an abstraction of) "the GPU memory" now. The code that pull the static geometry from an Ogre v2 mesh is already there, that's what is used by the "static mesh to shape converter".

I haven't touched that code since last april, so it's a bit rusty in my mind. ^^

I tested everything on Linux (g++ 7). "cmake - make - sudo make install" is your friend to build the static lib and install it in /usr/local/{lib, include} in a BtOgre21 subfolder. It *should* find your Bullet (install that from your distro's package) and your (installed from source) Ogre 2.1 without much trouble.

hedphelym · Post by **hedphelym** » Thu Jul 13, 2017 5:38 pm

Do you just build againt the current bullet source, or does it need a specific version?
(I cannot seem to find any info about what bullet SDK version I should build against, so I just assume the latest?).

Their latest tagged version is this one:
https://github.com/bulletphysics/bullet ... tag/2.86.1

Ybalrid · Post by **Ybalrid** » Fri Jul 14, 2017 11:15 am

Any recent version should work. I personally use the latest. But don't sweat it, the "-dev" (in the debian/ubuntu way of calling them) version of the packages for bullet in your Linux distribution repository should work.

If you want to build it from source, use the latest stable release.

hedphelym · Post by **hedphelym** » Fri Jul 14, 2017 11:17 am

Ok great!
I did get some errors building it yesterday, but I'll give it a try again today.
Yesterday I worked on my CentOS 7 workstation (got bullet (latest stable) \ ogre (latest 2.1 version) compiled, but btOgre21 failed), I did the cmake steps and all that.
I will try today om my laptop with debian on it, if I get the same issue there I'll let you know how it goes.

Ybalrid · Post by **Ybalrid** » Fri Jul 14, 2017 11:27 am

Post all the errors you have here. It's probably a stupid error on my CMakeList file. I only tested it on ArchLinux (beside windows and the whole mess it is to set path to bullet and ogre in the config...) and that's probably not the best idea... ^^"

hedphelym · Post by **hedphelym** » Fri Jul 14, 2017 11:41 am

It was some declaration errors, so it seems to just be something relatively simple.
I will post the log as soon as I can when I get home later today.

Mh... what compiler are you using? if gcc, can you post a `gcc --version" output ?

the syntax

Code: Select all

using some_type = known_type;

is the "more modern" way of doing typedef in C++11 and above. From that log, your compiler should support that with " --std=c++11", as other "modern" c++ features I'm using aren't compiling either apparently (e.g. "Constructor() = delete" or "auto".

I'm not a CMake expert, I may have forgotten something to tell him to set the compiler to use the modern standards of C++. I'm currently building Ogre 2.1 in an OpenSuse VM, so I can't test if the configuration still works right now ^^"

It is old - so I do not feel the need for you to do a lot of work to support a old version.
I will most likely switch OS to something else in a while.
But - as I mentioned, the other things compiles fine - so if it is possible to get BtOgre21 to compile as well with this then I'd appreciate it, but do not spend a lot of time on it if it works with debian\ubuntu\suse etc out of the box.

gcc --version output:

I updated the cmakelist file, pull the repo again and it should work out of the box, but you need CMake 3.1 or up. ^^"

edit: your compiler version should be fine.

Okay, that''s interesting. You have a conversion error on an argument in a function call...

Its seems the correct tipe of "indexOffset" hasn't been deduced correctly when initializing it at line 523. Should be an array of ints or unsigned ints, not an std::initializer_list<> of ints. It's probably just a syntax problem or a small confusion between C++11 and C++14. in that case, it's supported in GCC since version 5.

However, it should be an easy fix in my side. I've already done it. Can you please pull the repo and retry?

hedphelym · Post by **hedphelym** » Sat Jul 15, 2017 8:57 am

BtOgre21 compiles now! Thank you so much.
The last fix seems to be the demo (I guess it's the same kind of issue)?

Oh, yeah, same basic issue and same fix. already pushed to GitHub...

It should be good for the "compiler configuration side" for you, but it may have some "code" problems like last time, so I'm waiting for you to report me that ^^"

Also the "demo" is really minimal and has a lot of dead code that was using an old Ogre "(tutorial) application framework" that I didn't bother to replace by the thing used in the new Ogre's samples, I just hacked together something that will work.

Ybalrid · Post by **Ybalrid** » Thu Jul 27, 2017 3:36 am

Sorry to double post; I just wanted to point out that hedphelym helped me to find some issues both in configuration and code that prevented the library and the demo to build properly on some Linux distros.

Contrary to Ogre, this is written in C++11 and assume you have access to an actual C++11 compliant compiler (it's 2017 ^^").

I"ll update the first post, but if anybody want to try the lib, you should either build the master branch (or the latest release : https://github.com/Ybalrid/BtOgre21/rel ... ag/1.1.122) from source, and link against with the latest version of Ogre 2.1 available.

The demo now call the new "getDefaultPaths" on the HlmsPbs and HlmsUnlit classes to get the list of paths to construct the archives for these HLMS without hard-coding them you the "library user side". I had some breakage when the shader templates where refactored. Twice. (those pesky "any" folder.

). To "properly" use theses methods, don't look at my example here, go check the tutorial/samples, they have been updated to demonstrate this ^^"

I helped Ybalrid a bit by adding some features to the demo project included with BtOgre21,
the latest feature added is 'wasd + mouselook' for camera, and hit spacebar to spawn dynamic shapes into the scene, I'll help out by adding more things soon.

Screenshot from the demo (running on Debian testing):
