Hello everyone,

Anyone done any macruby opengl?

I am trying to get Hillegass's opengl example going in MacRuby.

My MacRuby version falls over in the drawRect method of an NSOpenGLView subclass, when it hits the glut function calls.

eg: glutSolidTorus(0.3, 1.8, 35 , 31)

It does not have problems with previous open gl methods/functions eg:

def drawRect(r)

glClearColor(0.2, 0.4, 0.1, 0.0)

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

glMatrixMode(GL_MODELVIEW)

glLoadIdentity

gluLookAt(@radius * Math::sin(@theta), 0, @radius * Math::cos(@theta), 0,0,0,0,1,0)

lightPosition = [@lightX, 1, 3, 0.0]

glLightfv(GL_LIGHT0, GL_POSITION, lightPosition)

if !@displayList

@displayList = glGenLists(1)

glNewList(@displayList, GL_COMPILE_AND_EXECUTE)

glTranslatef(0,0,0)

glutSolidTorus(0.3, 1.8, 35 , 31) <= error occurs here `drawRect': undefined local variable or method `glut' for #<GlissView:0x10df210> (NameError)

I am actually uncertain whether it is a MacRuby issue or just that I am not loading the glut framework or requiring it properly or something else.

Both the OpenGL and GLUT frameworks are in the Xcode project , and i do the framework calls:

framework 'Cocoa'

framework 'OpenGL'

framework 'GLUT'

in rb_main.rb. Though in fact it seems to not fall over any earlier if i remove the last two framework calls.

I am using macruby version 766.

Any ideas?

cheers and thanks,

John
