status of Fortran API to Vulkan graphics (the "new" openGL)
As many might know, Vulkan has been released 2 days ago on Feb 16, 2016:
"The Khronos Group announces the immediate availability of the Vulkan 1.0
royalty-free, open standard API specification. Vulkan provides high-efficiency,
cross-platform access to graphics and compute on modern GPUs"
This is the "new" openGL, called Vulkan.
Any one knows if there is any work by any one or company to make a
Fortran thin API for Vulkan? The API in in C as it stands.

The header files look fairly easy to translate to Fortran, but
installation of the drivers failed, so I won't be able to do
anything with it.

Does anyone know what graphics APIs are used for console programming

and I can see the Xbox using DirectX. I'm asking because I plan on becoming

...openGL for turtle graphics
I am developing a Logo-like turtle graphics system in the
programming language J http://www.jsoftware.com/ . At present the system
is implemented in a graphics system called "gl2". J is adopting "openGL"
and I am assuming it is a much richer graphics environment. openGL likely
includes sprites or layers or some other feature that would make managing
turtles separately from the background much easier. There may also be
openGL features for screen wraparound and slide controls for window
Are there any existing openGL implementations of such systems that

lot of other potentially unportable stuff involved. However most game
engines are very portable, and h...OpenGL For Non-Graphics Processing
I don't know if it's of interest to anyone in here, but I thought it may be
worth mentioning a product that uses shaders to harness the processing power
on modern GPU's, as it might turn a few wheels in your own minds.

Hi, what api would you all recommend for doing GUIs? Since I am primarily a
linux user, I was thinking of the GDK set, but having programmed GUIs in
Java for a few years now (which is exceptionally easy, but perhaps only
because I'm used to it), I was wondering if there were any 'easier' (for
want of a better word) c++ gui apis one could consider?

You don't. That feature is not part of 1.1.x. You can do the obvious
things like using multiple single-pixel lines to simulate a larger
line, or filled rectangles. Or upgrade to a newer Java version.
...2D vector graphics with OpenGL
With OpenGL and the Common Lisp Application Builder project it is easy to
create nice 3D animations:
(the lispbuilder-opengl-package will be released later at Sourceforge)
But OpenGL is useful for fast 2D vector graphics, too, because drawing
operations are accelerated by the graphics card. I've implemented a very
basic SVG path parser (in 16 lines with lispbuilder-lexer) and used the SVG

I am pretty new to OpenGL. After trying out a few examples, i
downloaded the Mesa source code and looked at the 3D driver (ATI :
r300) to see what operations are typically accelerated. I guess that
is not a simple task that can be done quickly with so many
indirections in the code :-) Some are obvious where ctx->Driver
functions are initialized by the driver. Then there are the software
fallback modules vbo etc. also that initializes the Driver functions.
For example, i was trying to see if the Vertex operations like
glVertex2f() are accelerated. I was unable to find it out. Is th...What about Lisp and OpenGL (or other graphics libraries)??
I need to include some displays in a program so I would really like to
have an opengl library, like C++ does. However, from what I have seen
on the net, there is no standard library and what's there seems more
like incomplete patchwork.
Anyone knows how to gain graphical capabilities using Lisp? do I have
to code that in C/C++ and then communicate through ports or something?
Any and all help greatly appreciated :)

I am trying to create an animation of a piecewise function. I have a graph of a ball rolling and I would like to combine an animation for one equation of motion for the first part with another equation for the second part of the motion. It is easy enough to create the two animations individually, however I am stumped on how to combine them into one continuous animation.

Python's OpenGL.Tk binding makes simple 3D drawing a snap! The default mouse

combinations- without any success.
Is there a work-around? The docu for the binding is somewhat obscure and one
has to guess a lot ;-) I haven't figured out yet how to use AutoSpin ....
I am using Windows2000
