Fernando,
thanks for the tips. I read about lumiere before, but I'm not
looking for a complete 3d framework, just the opengl wrappers to do some
experiments. A complete framework would be too much for what I want to try
(hw acelerated 2d animations). Anyway, your pdf gave me a better idea of the
status of all the available projects.
As of Croquet, yes, someone decoupled the OpenGL part (which is the same I
tested yesterday and depends on Ballon3D). I finally was able to load it in
pharo! If anyone is interested here are the steps:
Take a pharo image (mine had FFI and VMMaker already loaded, I don't know if
they were needed at all)
In monticello add squeaksource.com/Balloon3D. Open it and load just this
packages in order: Balloon3D-constants, Balloon3D-kernel, Balloon3D-math.
Now add squeaksource.com/OpenGL and load it.
That's all to load it, to try it, doit this code, and when you get errors
change occurrences of Smalltalk to SmalltalkImage current.
ogl := OpenGL newIn: (0...@0 extent: 3...@300).
green := 1.
canvas := OGLCanvas new initialize: ogl.
fade:= 0.
1000 timesRepeat: [
ogl glClearColor:0 with: fade with: 0 with: 1.
ogl glClear: 16r4000.
ogl swapBuffers.
fade := fade + 0.001.
].
fade := 0.
I think the best way would be to use AlienOpenGL, which is the future, but
for that I'll have to wait alien support in linux.
Regards,
Javier.
