[Pharo-users] CrashDetector made for sprint

Dear Pharo users, We made a short script with Guille during the Pharo sprint to detect at startup when image crashed, and propose to open changes browser to recover lost changes. It should be useful for beginners who do not know of the Changes Browser. It should be available tomorrow on Catalo

[Pharo-users] OpenGL project

Hi, I would like to do a bit of OpenGL in Pharo, but it does not seem to work at the moment. Tried NBOpenGL with a spur image (50560): _ fails at installation from configuration browser (need to click again on installing to get all classes) _ demo "GLTTRenderingDemo new openInWorld" fails at NB

Re: [Pharo-users] OpenGL project

There's (hopefully!) no question of throwing it away already. That represents too much work, and pretty good design choices IMO. Yet I'm still pretty new to Pharo/Smalltalk so simply need time. At the moment I am only practicing on a GLFW binding. Now, I do believe in OpenGL and hardware renderi

Re: [Pharo-users] FFI return by reference

Hi, I tried lots of ways to pass an array, based on the few examples found here and there. My example is: GLES2Buffer class>>gen: n into: buffers self ffiCall: #(void glGenBuffers(int n, int* buffers)) With buffers := FFIExternalArray newType: 'int' size: n (or FFIExternalArray gcExternalNe

[Pharo-users] Constants and the Playground

Hi, My work on OpenGL ES is almost done, and I am now trying to play with it in the Playground. However, since constants are stored in a pool dictionary you have to create a class importing it to encapsulate your OpenGL calls, so cannot just write snippets in Playground. This is very annoying f

[Pharo-users] OpenGLES2 binding available!

Hi all, My tiny binding for OpenGLES2 is ready :) http://smalltalkhub.com/#!/~ThibaultRaffaillac/OpenGLES2/ It takes a different direction than that of NBOpenGL. I found the support for all versions of OpenGL overwhelming, both for beginners and to maintain. With a limited number of functions I

Re: [Pharo-users] Intro to Microsoft COM for Smalltalkers

I am not very fond of event loops in general, because they imply "many inputs, one output" (process all pending events, then update screen). For Morphic this is fine, because it displays on one screen, refreshing at/around its frequency. But there might be other screens, or network-output, file-

Thanks for these mails, that's actually very helpful! I am working on a shorter syntax for animations at the moment (than GLMAnimation, Viva, Bloc-Animation), and could not find a proper equivalent to requestAnimationFrame (i.e. that would be independent of any UI yet in sync with display, and a
