3D Ruby Process Screencasts

From: Preston Lee on 28 Jul 2010 14:12 For those wanting to do 3D stuff with Ruby Processing, I also have a few screencasts up on YouTube, as well as some F/OSS code available on GitHub. http://www.prestonlee.com/2010/05/17/3d-osx-applications-with-ruby-processing-screencast/ Marc-antoine Kruzik wrote: 3D with Ruby (Ogre ?) 12-Jan-10 Hello, I am french, sorry for my mistakes.

[Note: parts of this message were removed to make it a legal post.] Ogre.rb is not at all ready for use right now, but other than my work there I do not know of any workable Ruby wrapper to a 3D engine. If you are looking to just work with 3D yourself, there is always straight OpenGL, and a few Ruby wrappers around that library. When you say "do 3D with Ruby", what kind of project are you looking to build?

Create cubes with textures, some houses. I am a 2D games programmer, so I would work a bit in 3D. I created a 3D graphical engine from a 2D library. But using a real 3D library will be better. I remember OpenGL is a bit strange to me, because of the vertex system. But there are many tutorials and informations about OpenGL, so I think it could be the better choice. Thank you two for your advices. -- Posted via http://www.ruby-forum.com/.

Hello Marc-antoine: OpenGL has had shaders for quite a while: http://en.wikipedia.org/wiki/GLSL http://www.opengl.org/documentation/glsl/ All you need to do is write the shaders and load them into the GPU via OpenGL's GLSL API. OpenGL and Microsoft DirectX/3D have been leapfrogging each other for the past 10 years and the shader capabilities of each are pretty comparable. Because of OpenGLs extension mechanism OpenGL will sometimes get a feature before DirectX/3D but unfortunately the acquiring the Pixel Format / Rendering Context (roughly equivalent to the capability-bits in DirectX/3D) in OpenGL has gotten really ugly because of that.

Hello Michal: s>upport OpenGL 2.0 or greater GLSL shaders. I implemented the OpenGL 2.0 or greater version of the shader functions so you will likely need to install OpenGL 2.0 or greater drivers for your video card. It looks like you are running the software-only OpenGL drivers that come with Linux. In the initialize procedure I do the following check for the required OpenGL functions: if not (GL.respond_to?('CreateProgram') and GL.respond_to?('CreateShader') and GL.respond_to?('ShaderSource') and GL.respond_to?('CompileShader') and GL.respond_to?('AttachShader') and GL.respond_to?('LinkProgram') and GL.respond_to?('DeleteShader') and GL.respond_to?('DeleteProgram')) puts('Error - The program has terminated because the environment does ' + 'not support OpenGL 2.0 or greater GLSL shaders.') exit end In theory, if your MESA / SGI driver supported shaders through ARB extensions (like some earlier OpenGL's did) instead of as built in functions (like OpenGL 2.0+ in the recent ATI, Nvidia and Intel drivers) then you could modify this section and other sections of code to use the alternate (i.e. older) function names. However, I do not believe your drivers support shaders at all.

The problem is that Intel does not do special driver for Linux, their hardware is supposedly supported by X11/Mesa and the proprietary drivers for ATI/nVidia cards simply do not work (tried with recent cards about half an year ago). Running a demo is as far as I got in using OpenGL so I guess I will pass on this for now. support It supports fragment and vertex programs. I do not know it that is sufficient but I think FireGL V3350 should support some shading.

The stability has also worsened recently. Too many chipset revisions with different hardware issues I guess.

I do most of my work in Windows. I just booted my desktop into Mint Linux 7 which already had the Nvidia 3D drivers installed then installed ruby 1.8.7, glut, ruby-opengl and ran the gears_with_shaders.rb file just fine. I have had the best success with Nvidia under Linux. Even the Geforce Go 6150 in my old HP tx1000 laptop supports OpenGL 2.1 in Mint Linux 8. I have had some success with ATI in Linux but it varies greatly for different models and from distro-to-distro. I'd heard that the Intel x3100 IGP and later chipsets were supposed to support OpenGL 2.0+ but have not had direct experience with them.

The glue for binary ATI drivers did not even compile for me. The mesa library should support OpenGL 2.1 since version 7 but it seems that support for different features in hardware accelerated drivers varies per chipset due to hardware limitations or some features may be simply not implemented for some hardware. I would also think that higher level libraries like Ogre or CrystalSpace would make a better job at isolating the developer from these hardware and driver differences than raw OpenGL. heard GL I do not have such system at hand either, only i945G/GM (something like GMA900 or GMA950) here.
