I searched on mono touch page but there are not much graphics examples. Could someone point me to some introductory graphics in mono touch?
Thanks.
Checkout XnaTouch. They have samples that you can run on the device and sim. I'd recommend pulling the source code from the repository as the last zipped version of the framework is from Dec '09.

I want to create a 2D sprite that mimic the provided image:
http://a4.mzstatic.com/us/r1000/069/Purple2/v4/e6/0d/73/e60d73a8-6d78-64c2-dd59-9aabb54c7837/mzl.ujapwanw.320x480-75.jpg
and create different face expressions as provided sprites to unity3d in order to create an android application has multiple face expressions with those sprites... so my question... is what exactly the software I might use through out this process ??
Please, let me know the simplest step-by-step procedures, as I am in my first steps in computer graphics.
Thanks a lot.
Image manipulation is what you are looking for. To modify the current image you have and generate other facial expressions from it, you need to be very good at math. Image manipulation is not a basic stuff and I hope you are not new to programming.
Now that you understand that, you need OpenCV to be able to do this. You need to make a wrapper for it in c#. You can get the already made wrapper [here].1 https://www.assetstore.unity3d.com/en/#!/content/21088 .It works on Windows,Mac, Android and iOS and will save you time. Its NOT free but the price is worth it compare to the time you will spend building the wrappers for all platforms.
Once you get this, you can start learning OpenCV from the following link.

If you the Unity plugin I mentioned, you can ask the author of the plugin to help you out if you are tuck.
i am a newbie at graphics for embedded system. i have worked with OpenGl, Unity, WPF etc for graphics but as a hobby project i wanted to run games on embedded platforms like [arduino and Raspberry(without Raspian)].
Can someone please refer some guide or road map for me in this regard. For performance issue i want to target only 2D but good proper games and the system should work like a gaming console. [off course the game controllers are least of my worries since i am an electrical engineer :D ].
Please don't close this question without answer. i know there are a lot others but i wanted answer to my problem for 2D games ...
P.S. i would really appreciate solutions that are widely accepted,
This isn't really a programming question per se, but it is related. I'm looking for the instructions on how to install FMOD.
I want to do extra credit for my computer graphics assignment - sound effects. A teammate wants me to go with something simple, and he suggested that I use FMOD Ex. (If you guys can think of something better, do suggest it, but so far FMOD looks more promising compared to SDL, OpenAL, etc.)
Right now I'm having a really hard time finding the instructions for installing the latest version of FMOD (audio content creation tool) on Linux Ubuntu 12.04 LTS (32-bit) so that I can use it in g++ with OpenGL. I checked out this YouTube video: http://www.youtube.com/watch?v=avGxNkiAS9g, but it's for Windows. Then, there is a Ubuntu Forums thread which redirected me to this page: https://wiki.debian.org/FMOD, and it has some dated instructions. I've downloaded FMOD Ex v. 4.44.24, which I believe is the latest version. Now I'm looking at eight libraries: libfmodex.so, libfmodex64.so, libfmodex64-4.44.24.so, libfmodex-4.44.24.so, libfmodexL.so, libfmodexL64.so, libfmodexL64-4.44.24.so, libfmodexL-4.44.24.so ... not knowing what to do. I've looked everywhere I could think of: here, YouTube, Google, Ubuntu forums, ... and came up with zilch. I can't think of any other place to ask this question.
If you do know how to install FMOD off the top of your head, drop me a line.
Please help. Thanks in advance.
Copy the .so files in /usr/local/lib/, the header files in /usr/local/include/fmodex/, and you're good to go.
I am trying to make an application for listening to podcasts. Each podcast is an mp3 file, around 50MB in size. After reviewing the Using Audio chapter of the Multimedia Programming Guide, I decided to use AVPlayer, as the other options did not seem appropriate. However, the more I work with AVFoundation, the more complicated it seems and I have a feeling that simply streaming an mp3 file should be easier. Plus on the top of this document, there is a note stating:
Important: This document contains
information that used to be in iOS
Application Programming Guide. The
information in this document has not
been updated specifically for iOS 4.0
Does that mean that I have some other options, or that AVFoundation is maybe an overkill for what I need to do? I would really appreciate it if someone could clear things out a bit and let me know if I'm making something wrong here.
Thanks in advance!
You should explore Cocos Denshion.
http://www.cocos2d-iphone.org/wiki/doku.php/cocosdenshion:cookbook
The audio engine comes with cocos2d, and it is just 5 classes you can include with your project.
It's very simple to use, as you can see from the above link. It's basically just a wrapper for some AVFoundation classes.
The only trick will be to stream your mp3, but it looks like you can simply update the Cocos Denshion CDAudioManager to hand a URL to the AVAudioPlayer, as a start. Whether or not that satisfies your streaming requirement, I don't know.
At the very least, it will give you some AVFoundation code to study.
I just found a pdf with a nice overview of some possible options from this course blog. Together with Julian's suggestion this is all I could find so far.
Is there a freely available library to create a MPEG (or any other simple video format) out of an image sequence ?
It must run on Linux too, and ideally have Python bindings.
I know there's mencoder (part of the mplayer project), and ffmpeg, which both can do this.
ffmpeg is a great (open source) program for building all kinds of video, and converting one type of video (a sequence of images in this case) into other types of video.
Usually it is utilized from the command line, but that is really just a wrapper around its internal libraries. It is expressly available to be used from within another program.
There are also python bindings that wrap the c api, though this particular project doesn't seem to be getting the best support (there are probably other projects out there doing the same thing).
There's also this link where someone has used ffmpeg to do something similar to what you're looking for.
GStreamer is a popular choice. It's a full multimedia framework much like DirectShow or QuickTime, has the advantage of having legally licensed codecs available, and has excellent Python bindings.
in c++ OpenCV (open source Computer Vision library from Intel) let you create an AVI file and just push frames inside...
but it's like shooting with a cannon to a fly.
Not a library, but mplayer has the ability to encode JPEG sequences to any kind of format. It runs on Linux, Windows, BSD and other platforms and you can write a python script if you want to use it with python.
ffmpeg has an API and also python bindings, seems to be the way to go !
Thanks
