I've uploaded new versions of these two packages to hackage: GPipe-1.0.2: * Removed rasterize and made rasterizeFront work for other primitives than triangles instead. * Fixed notB Vertex and Fragment instances Vec-Transform-1.0.1: * Added rotationLookAt Cheers Tobias Bexelius _________________________________________________________________ Windows Live: Dina vänner får dina uppdateringar från Flickr, Yelp och Digg när de skickar e-post till dig. http://www.microsoft.com/windows/windowslive/see-it-in-action/social-networ…

hopengl 2.4.0.1 slowdown
by Csaba Hruska 11 Oct '09

11 Oct '09

Hi! I've upgraded my haskell programs to opengl 2.4.0.1 and I've noticed massive (3X) slowdown. I did only type fixes on code. Is it normal? Csaba

Open GL 3.2
by Alexander Göransson 11 Oct '09

11 Oct '09

Hello! (new to the list) I am taking a course in computer graphics, so i installed the latest version of the OpenGL package through cabal. At the top of of the documentation page it says OpenGL 3.2, but when i read different parts of the documentation on hoogle it says OpenGL 2.1 every here and there. What's what? (and if I can, how do i load my GLSL code?) hello! // Alexander, Gothenburg

RE: [Haskell] ANNOUNCE: OpenGLRaw 1.1.0.0

> * Fall back to GetProcAddress on Windows when WGL doesn't find an API > entry. This should fix problems using core functions with some driver/OS > combinations. I guess this fix is supposed to be the one I suggested a few weeks ago. However, after installing the latest opengl and raw packages I get the same old problems again, and in cbits/HsOpenGLRaw.c this is the only thing I find: void* hs_OpenGLRaw_getProcAddress(const char *name) { return wglGetProcAddress((LPCSTR)name); } Cheers Tobias Bexelius _________________________________________________________________ Hitta kärleken nu i vår! http://dejting.se.msn.com/channel/index.aspx?trackingid=1002952

ANNOUNCE: OpenGLRaw 1.1.0.1
by Sven Panne 11 Oct '09

11 Oct '09

A new version of the OpenGLRaw package has been uploaded to Hackage. This is a bug-fix-only release, fixing the retrieval of core OpenGL API entries on Windows. This fix should have already been included in the previous 1.1.0.0 version, but it was accidentally left out (thanks to Tobias Bexelius for pointing this out). Cheers, S.

ANN: Extensions to Vec uploaded (useful for GPipe programs)
by Tobias Bexelius 10 Oct '09

10 Oct '09

Hi, I've added two extensions to the Vec package: Vec-Transform and Vec-Boolean. These two packages are more or less essential when programming GPipe programs, but can also be useful for other applications as well. * Vec-Transform provides some 4x4 transform matrices such as perspective projection and rotation. * Vec-Boolean provides Data.Boolan instances for the Vec data types.

GPipe example and screenshot
by Tobias Bexelius 08 Oct '09

08 Oct '09

I've put a simple GPipe example (including a screenshot) on the haskellwiki now, showing off an animated spinning box. You'll find the page here: http://www.haskell.org/haskellwiki/GPipe Later on, I will add more examples, and also some kind of GPipe-tutorial. Hang in there...

ANNOUNCE: GPipe-1.0.1: A functional graphics API for programmable GPUs
by Tobias Bexelius 06 Oct '09

06 Oct '09

I've just uploaded a new version of Gpipe that fixes these bugs: * Textures should now work on OpenGl 2.1 (required OpenGl 3.x previously). Thanks to Jake for the bug report. * Added link to GPipe homepage. Still not much there though (just Jake's example code), check back in a few days. /Tobias Bexelius > Date: Tue, 6 Oct 2009 08:58:35 -0500 > From: jake.mcarthur(a)gmail.com > To: tobias_bexelius(a)hotmail.com > CC: mr.hugo.gomes(a)gmail.com; hopengl(a)haskell.org; haskell(a)haskell.org > Subject: Re: [HOpenGL] RE: [Haskell] ANNOUNCE: GPipe-1.0.0: A functional graphics API for programmable GPUs > > Speaking of texture, I tried rendering to a texture and sampling it and > got an error: > > Main: user error (unknown OpenGL extension entry glUniform1uiv, > check for OpenGL 3.1) > > I'm on Linux 2.6.30 with Mesa 7.5.1.

Yeah, that is sad indeed. Right now, the GLUT window concept is wired in quite tightly to support multiple windows (textures are tagged with Window objects because they need to be transferred via RAM if used in new windows, and so on). I'll try to adress this issue in a later version... > Date: Mon, 5 Oct 2009 09:12:28 -0500 > From: jake.mcarthur(a)gmail.com > To: mr.hugo.gomes(a)gmail.com > CC: tobias_bexelius(a)hotmail.com; hopengl(a)haskell.org; haskell(a)haskell.org > Subject: Re: [HOpenGL] RE: [Haskell] ANNOUNCE: GPipe-1.0.0: A functional graphics API for programmable GPUs > > Hugo Gomes wrote: > > great... > > > > now, how do i use glfw with it ? :) > > Yeah, I was disappointed to see that the only toolkit it works with when > rendering to a window is GLUT.

I'm planning to make some examples and upload them in a week or so.
