<br>You don't have to learn assembly to use OpenGL with Nativeboost.
<br>Also, replying to previous post, it supports all 3 major platforms -
<br>mac, unix and windows.
<br><br>As for making NB working on Squeak, except from VM there's only one

<br>> thanks Hans-Martin. I'll update my videos with that bit of info too.

<br>> I have been playing quite a bit with NativeBoost lately and it offers some
<br>> very nice features that anyone wanting to make a game or other realtime-ish
<br>> application will find beneficial, including the ability to create a
<br>> "cascade" of foreign file calls within a single method, or even program a
<br>> bit of custom x86 assembler. I don't know what will be involved to port it
<br>> to Squeak, but Igor's talk suggests that the only "special" bit is already
<br>> present in the VM, which should work with either Pharo or Squeak. The rest
<br>> is just glue code at the Smalltalk level, which means that it is perfectly
<br>> doable to get it working on Squeak, in theory at least.
<br>>
<br>> Native boost also offers a way of passing an arbitrary ByteArray to an
<br>> external function as though it were a normal pointer to a bit of malloc-ed
<br>> memory, which can be VERY useful with certain libraries, that and the
<br>> ability to actually malloc memory for a ByteArray from the OS level heap,
<br>> opens up all sorts of possibilities like having an external lib render
<br>> directly into a BitMap object asynchronously from its own OS level thread so
<br>> that each update can show the library's progress in a morph without any
<br>> further coding.
<br>>
<br>> I'm actually working on a simple MandelBrot Set generator lib in C to demo
<br>> this.
