OpenGL Workshop - 26th

[Benjamin Blundell]

Hi all. Just to let you know the workshop is still go. I reckon it'll be short (10:30 for an 11am start till about 4pm). I'll be covering the very basics, so Triangles, Shaders, Buffers, Matrices, Vectors, Transforms, the OepnGL pipeline and such. Its a basic, quick introduction and designed for beginners.

You will need:

1) A Laptop with a discrete 3D Card (so no Macbook Airs) capable of OpenGL2.1 Core or above

2) A C++ Compiler from the following - Clang, GCC, MSVC

3) A Dev environment such as:

    - GCC Toolchain under linux with OpenGL Libraries, Boost and similar

    - MSVC 10 (So Visual Studio 2010 Express or Pro) with Boost compiled and installed with Visual studio service pack 1

    - Clang/GCC on the Mac with the ability to run from the command line

4) CMake

5) Working knowledge of C++

The idea will be, I'll have a few exercises, a few talky bits and then we can get some colours and things drawn and played with. There is a substantial setup time, as dev environments for OpenGL C++ can take time. I'll be posting up full instructions in the next couple of days.

Finally, if anyone knows C++ and OpenGL and fancies lending me a hand, I'd be really happy as we do need bodies to help people install stuff, code stuff and have fun playing around with pretty graphics so if you can spend 5 hours this sunday, I'd be really happy!

Cheers

Which version of OpenGL, I may be wrong but IIRC there's a substantial difference between 2.x and 3?

Also are you thinking of using any extra libraries (GLUT, GLEW etc)? as some of these can be buggers to set up (e.g. anything on mac). 

I'll try and make it if I can, I had a lot of fun poking through various tutorials and would love to actually do a bit more.

Ultimately, yes, there is a large difference. OSX Still doesnt support 3 fully! >< But I'll be going with the techniques applicable to 3 - essentially non-immediate mode rendering. GLFW is what I'm going for and yes, thats a bitch to setup but thats what im doing this week - making the transition a little easier.

[Benjamin Blundell]

Yes, also GLEW and GLM but I've included these in my own special build so the majority of that is hidden away. I've got CMake on the job. Just testing compilation on Windows at present. Should be fine in the end.

Code for the session has been released here:

Please read, download and install before the Sunday session if you can! Its not the easiest of code but I've taken out a lot of the hassle of getting setup :)

Cheers

Thanks to everyone who came along. I had fun and although we had some code errors (sorry) most of you seemed to get stuff up and running. Any feedback is greatly appreciated. If people are keen, I'll run another one day.
