Yoshi. + +James A. desperately wanted to get the OpenGL Ruby bindings working on his Mac, +but they wouldn't even compile on OSX. After a little bit of tweaking, he made +his patched bindings available to the ruby community in a very informal manner. + +John G. then wanted to clean it up and add some docs to it, and so started +tweaking and put up a new site and made his changes available. + +Then Peter M. came along and decided to try updating ruby-opengl using SWIG, +as it seemed easier than doing everything by hand. Peter wrote the new code, +John started the actual RubyForge project, put up a new site, and Peter +committed the code. + +Thu M. V. joined the project with a lot of energy, and the mailing list +was showing a good bit of activity. + +After some experience, we began to question whether SWIG was necessary/helpful +for a project of this nature. The leaning was that people want to abandon +SWIG and go back to maintaining the binding files by hand. Thu even provided +a script to help with the manual coding that would be required without using +SWIG. + +The reasoning at the time was: + +Pro-SWIG: + +* Could use the .i files for another project, perhaps (OTOH, we couldn't + use previous .i files on this project...) + +* It's supposed to require less manual coding. + +Con-SWIG: + +* yet another tool to learn + +* OpenGL isn't really all that big + +* OpenGL doesn't change a lot + +* A lot of boilerplate and overhead in the generated files because SWIG is + a general tool. + + +In September 2006, we stopped using SWIG. Thu and Peter began fine tuning +Thu's original `utils/mkwrap.rb` script. + +Development stalled in October 2006. + +Development picked up again towards the end of 2006.

It has one +downside though - due to Ruby's naming scheme, you cannot use constants +which begins with number, e.g. GL_2D would under this syntax be (GL::)2D +which is illegal. + +All three variants of syntax will continue to be supported in future, +so it's up to you which one you choose to use. + +The rest of this tutorial will use the C syntax. + +Calling syntax +-------------- + +Function parameters +-------------- +For most types the ruby syntax follows the C API. If needed, ruby will do +automatic parameter conversion to required type if possible. Example: + + {{ruby}} + glVertex3f( 1.0, 1.0, 1.0 ) # matches C syntax + glVertex3f( 1, 1, 1 ) # equivalent to the above + glVertex3f( "string", 1, 1 ) # raises TypeError exception + +Arrays are passed/received as Ruby arrays: + + {{ruby}} + vertex = [ 1, 1, 1 ] + glVertex3fv( vertex ) + +For functions with multiple parameter-number variations (glVertex,glColor,...) +we define 'overloaded' functions, as in: + + {{ruby}} + glVertexf( 1, 1 ) # will call glVertex2f() + glVertexf( 1, 1, 1 ) # will call glVertex3f() + glVertexf( 1, 1, 1, 1 ) # will call glVertex4f() + glVertexi( 1, 1 ) # will call glVertex2i() + ... + # and so on + + +Return values +------------- +In C, OpenGL functions rarely return values directly, instead you pass in pointer to +preallocated buffer and they will fill it with values; sometimes you have to even query +how big buffer you'll need to allocate. Ruby does this all for you, returning either single +value or array: + + {{ruby}} + glColor4f( 1.0, 1.0, 1.0, 1.0 ) + ... + color = glGetDoublev(GL_CURRENT_COLOR) + p color # will be [1.0,1.0,1.0,1.0] + + +Matrices +------------- +Matrices are passed and received as ruby array, or as ruby Matrix objects: + + {{ruby}} + matrix_a = [0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15] + matrix_b = [ [ 0, 1, 2, 3 ], + [ 4, 5, 6, 7 ], + [ 8, 9,10,11 ], + [ 12,13,14,15 ] ] + matrix_c = Matrix.rows( [ [ 0, 1, 2, 3 ], + [ 4, 5, 6, 7 ], + [ 8, 9,10,11 ], + [ 12,13,14,15 ] ] ) + ... + glLoadMatrixf(matrix_a) + glLoadMatrixf(matrix_b) + glLoadMatrixf(matrix_c) # same result + +You may also create your own matrix class and pass it this way, provided that it +is convertible to array (has 'to_a' method). + +Note that as OpenGL uses column-major +notation for matrices, you may need to call transpose() when working with +row-major matrices or arrays in ruby. + + +Textures and other raw data +------------- +Data for textures, arrays, buffers etc. can be specified either as ruby arrays or directly as raw packed strings - +strings that contains their direct memory representation (just like C arrays). If you need to convert between +ruby arrays and these strings, use ruby Array#pack() and String#unpack() functions. +Example: + + {{ruby}} + # create texture, 2x2 pixels, + # 3 components (R,G,B) for each pixel as floats + texture = [ + 1.0, 0.0, 0.0, # 1st pixel, red + 0.0, 1.0, 0.0, # 2nd pixel, green + 0.0, 0.0, 1.0, # 3rd pixel, blue + 1.0, 1.0, 1.0 # 4th pixel, white + ] + # convert it to string + # f = native float representation + # * = convert all values in the array the same way + data = texture.pack("f*") + ... + glTexImage2D( + GL_TEXTURE_2D, # target + 0, # mipmap level, + GL_RGB8, # internal format + 2, 2, # width, height + 0, # border = no + GL_RGB, # components per each pixel + GL_FLOAT, # component type - floats + data # the packed data + ) + +Reverse works just the same: + + {{ruby}} + ... + data = glGetTexImage( # returns the packed data as string + GL_TEXTURE_2D, # target + 0, # mipmap level + GL_RGB, # components per pixel + GL_FLOAT # component type + ) + # now convert it to ruby array + texture = data.unpack("f*") + ... + +For storage, packed strings are more memory efficient than ruby arrays, but +cannot be easily changed or manipulated. + + +Error Checking +-------------- +Starting with version 0.60.0, ruby-opengl performs automatic checking of OpenGL and GLU errors. +Functions: + + {{ruby}} + Gl.enable_error_checking + Gl.disable_error_checking + Gl.is_error_checking_enabled? # true/false + +When the checking is enabled (default), glGetError() is executed after each OpenGL call, and should error +occur, Gl::Error exception is raised: + + {{ruby}} + Gl.enable_error_checking + ... + begin + ... + glEnable(GL_TRUE) # will raise exception + ... + rescue Gl::Error => err + # err.id contains the OpenGL error ID + if (err.id == GL_INVALID_ENUM) + puts "Oh noes! You used invalid enum!" + ... + end + ... + end + +Some GLU functions may also throw Glu::Error - the handling is the same as above. + +It is usually good idea to leave error checking on for all your code, as OpenGL errors have habit to pop-up in +unexpected places. For now there is no measurable performance hit for error checking, although this may depend +on your graphic drivers implementation. + + +The Examples +----------- + +Various examples are in 'examples' directory of the bindings. To run them, manually pass them to `ruby` like: + + ruby some_sample.rb + +On windows, you may want to use 'rubyw' instead, which displays the standard output window +as some examples use the console for usage info etc. + +If you get 'opengl not found' error, and you installed ruby-opengl from gems, your +shell or ruby installation is probably not configured to use the gems; in that case type: + + ruby -rubygems some_sample.rb + +The `README` file in the `examples` directory contains some notes on the examples. + + +OpenGL Version and Extensions +----------- +To query for available OpenGL version or OpenGL extension, use Gl.is_available? function: + + {{ruby}} + # true if OpenGL version is 2.0 or later is available + Gl.is_available?(2.0) + ... + # returns true if GL_ARB_shadow is available on this system + Gl.is_available?("GL_ARB_shadow") + +For list of what extensions are supported in ruby-opengl see this [page](extensions.html) + +The extensions' function names once again follows the C API. Some extensions were over time +promoted to ARB or even to OpenGL core, retaining their function names just with suffix changed +or removed. However sometimes the functions semantics was changed in the process, so to avoid +confusion, ruby-opengl bindings will strictly adhere to the C naming, e.g. : + + {{ruby}} + # will call the function from GL_ARB_transpose_matrix extension + glLoadTransposeMatrixfARB(matrix) + ... + # will call the function from OpenGL 1.3 + glLoadTransposeMatrixf(matrix) + +Note: ruby-opengl is compiled against OpenGL 1.1, and all functions and enums from later +versions of OpenGL and from extensions are loaded dynamically at runtime. That means that all +of OpenGL 2.1 and supported extensions are available even if the ruby-opengl bindings are +compiled on platform which lacks proper libraries or headers (like for example Windows without +installed graphic drivers). This should ease binary-only distribution and application packaging. + + + +Selection/Feedback queries +----------- +Querying selection and feedback is different from C. Example: + + {{ruby}} + # this will create selection buffer 512*sizeof(GLuint) long + buf = glselectbuffer(512) + # enter feedback mode + glRenderMode(GL_SELECT) + ... # draw something here + # return to render mode + count = glRenderMode(GL_RENDER) + # at this point the buf string is freezed and contains + # the selection data, which you can recover with unpack + # function + data = buf.unpack("I*") # I for unsigned integer + # also, next call to glRenderMode(GL_SELECT) will overwrite + # the 'buf' buffer with new data + +The feedback query follows the same pattern, only the data are stored +as floats. + + +Vertex Arrays +----------- +In current state, vertex arrays are not very efficient in ruby-opengl, as it is not possible to change +the array content once it is specified, and there is overhead for converting between ruby and C representation +of numbers. Using display lists for static and immediate mode for dynamic objects is recommended instead. + +You can specify the data the same way as [texture data](#textures). Example: + + {{ruby}} + normals = [0,1,0, 1,0,0, 1,1,1] + glNormalPointer(GL_FLOAT,0,normals) + ... + glEnable(GL_NORMAL_ARRAY) + glDrawArrays(...) + ... + +This applies to all *pointer functions. glGetPointerv will return reference to the frozen string +previously specified. + + +Buffer Objects +----------- +Once again, in current state buffer objects (VBOs in particular) are not very efficient in ruby-opengl. +Unlike textures and vertex arrays, the data for buffers *must* be prepacked by using .pack() function, +as buffers does not retain information about the storage type. Mapping of the buffer afterwards is read-only. + +Like in C, buffer binding affects some functions in way that if particular buffer is bound, the related +functions (for example glTexImage) take integer offset in place of data string argument. This is also true +for getter functions (e.g. glGetTexImage) - instead of returning the data string, they take offset as they're +last argument (so in ruby they take one extra argument), and will write the data in the bound buffer as expected. + +VBO example: + + {{ruby}} + # specify 3 vertices, 2*float each + data = [0,0, 0,1, 1,1].pack("f*") + ... + # generate buffer name + buffers = glGenBuffers(1) + # bind to the name to ARRAY buffer for vertex array + glBindBuffer(GL_ARRAY_BUFFER,buffers[0]) + # here the data is specified, size is n*sizeof(float) + # note that you don't get to specify type, as buffers + # operate on byte level + glBufferData(GL_ARRAY_BUFFER,6*4,data,GL_DYNAMIC_DRAW) + ... + # here instead of specyfing the data, you pass '0' (or + # positive integer) as offset to the bound buffer + glVertexPointer(2,GL_FLOAT,0,0) + ... + glEnableClientState(GL_VERTEX_ARRAY) + ... + + +GLUT, SDL, GLFW.. +--------- +When it comes to low-level task like GL window creation, input and event handling, the first choice is GLUT, +as it is readilly available alongside OpenGL. However both GLUT itself and its implementations +have their drawbacks, and for that and other reasons there are number of replacement libraries. +You can use any of them with ruby-opengl (as long as there are ruby bindings for them). + +Here is example for [SDL](http://www.kmc.gr.jp/~ohai/index.en.html): + + {{ruby}} + require 'opengl' + require 'sdl' + # init + SDL.init(SDL::INIT_VIDEO) + SDL.setGLAttr(SDL::GL_DOUBLEBUFFER,1) + SDL.setVideoMode(512,512,32,SDL::OPENGL) + ... + Gl.glVertex3f(1.0,0.0,0.0) + ... + SDL.GLSwapBuffers() + ... + +and another example for [GLFW](http://ruby-glfw.rubyforge.org/): + + {{ruby}} + require 'opengl' + require 'glfw' + # init + Glfw.glfwOpenWindow( 500,500, 0,0,0,0, 32,0, Glfw::GLFW_WINDOW ) + ... + Gl.glVertex3f(1.0,0.0,0.0) + ... + Glfw.glfwSwapBuffers() + ... + + +GLUT callbacks +-------------- + +The GLUT callback functions are specified as Proc objects, which you can +either create with lambda as: + + {{ruby}} + reshape = lambda do |w, h| + ... + end + ... + glutReshapeFunc( reshape ) + +or by conversion from normal functions: + + {{ruby}} + def reshape(w,h) + ... + end + ... + glutReshapeFunc( method("reshape").to_proc ) + +Note: An older notation you'll see instead of `lambda` is `proc`. The +PickAxe v2 notes that `proc` is "mildly deprecated" in favor of `lambda`. +You'll also sometimes see `Proc.new` used in place of either. Pages 359-360 of +PickAxe v2 describe the differences between using `lambda` and `Proc.new`, +but for our purposes either will be fine. + + +Internals +--------- + +The directory structure follows current Ruby standards, with a few +extra directories added. + +* `doc/` -- Contains documentation for the project (from which this + website is generated). +* `examples/` -- Example programs. +* `ext/` -- Contains subdirectories, one for each of the three extension + modules (gl, glu, glut).
