Hi Derek,

thanks for the reply. I've inspected "SmalltalkImage current listLoadedModules" and "SmalltalkImage current listBuiltinModules" and there is no sign of "module:'Squeak3D'". I also checked my Croquet installation and again no sign of "module:'Squeak3D'" - however the Croquet image appears to have a different installation of OpenGL; there is no sign of Balloon3D*.

Do I need a "Squeak3D.dll" module is so where would I find it? Google points me to http://wiki.squeak.org/squeak/2874, which is interesting but that particularly helpful.

Are there two separate implementations of OpenGL in Squeak - one in Croquet and one in "standard" squeak.

Try inspecting the following to confirm the module is present:

SmalltalkImage current listLoadedModules

if not then same on:

SmalltalkImage current listBuiltinModules

Hi,

I'd like to experiment with OpenGL in Squeak. I found the promisingly titled "Howto - Loading OpenGL in Squeak 3.9" from Jakub Kozisek (http://lists.squeakfoundation.org/pipermail/beginners/2006-November/001451.h...) and followed the directions:

• install FFI and Balloon3D from SqueakMap. (I used the Universe browser

to install FFI version 3.9.1 and Balloon3D version 0.18.2)

• install OpenGL-ckl.4.mcz from Monticello repository at

http://www.squeaksource.com/OpenGL

• apply change set from

http://lists.squeakfoundation.org/pipermail/beginners/attachments/20061118/4...

• ensure squeak.ini contains: B3DXUsesOpenGL = 1
• OpenGLMorph new openInWorld.

Unfortunately the instructions resulted in the following error:

...

...

...

Error: Error a primitive has failed

Examining the stack trace the error was in:

B3DPrimitiveRasterizerState>>primInitializeBuffers

which reads: B3DPrimitiveRasterizerState>>primInitializeBuffers <primitive: 'b3dInitializeRasterizerState' module:'Squeak3D'> ^self primitiveFailed

I ran the shipped FFI tests and all tests passed. I'm running under windows using a VM from SqueakVM-Win32-3.10.6-bin.zip and an image sq3.9.1-7075dev08.07.1

I downloaded Croquet which displayed it's 3D world successfully, but would prefer a minimal OpenGL installation. I tried the Croquet VM with my image, but got the same problem.

Any ideas?

Nick

Not sure this will help in your case, but just for information, there are some plugin naming convention issues, the generated name does not always match the plugin name.

eg: internal plugin B3DEnginePlugin generated as Squeak3D internal plugin BalloonEnginePlugin generated as B2DPlugin internal plugin BitBltSimulation generated as BitBltPlugin internal plugin DSAPlugin generated as DSAPrims internal plugin DeflatePlugin generated as ZipPlugin internal plugin FFIPlugin generated as SqueakFFIPrims internal plugin KlattSynthesizerPlugin generated as Klatt internal plugin LargeIntegersPlugin generated as LargeIntegers
