Where are such examples? How can I try an example of OpenGl on my macbook?
I've tried to execute "SourceCityGL new" and I got an error "No suitable implementation found for initializing OpenGL context for your platform". No idea why I got this. I have the same error when I try "GLTTRenderingDemo new"
I am using Pharo 1.4 Summer. Do I have to install some libraries somewhere? I guess I have OpenGl installed on my mac.

The problem is that SourceCity loads the version from squeaksource. It should load the one from STHub.
I tried loading the latest version from STHub, but in the meantime the NBOpenGL code has changed a bit and SourceCity should be modified to adopt the new version properly (there are some DNUs).

You don't. It just works.
The problem is that different hardware has different features supported. During initialization of context i checking + asking for some capabilities. Looks like your machine does not supports them fully, or initialization logic is flawed.. Did you tried to use latest config of NBOpenGL on your machine?
What would be the hello world example in OpenGL in Pharo?
Anything which shows on screen, like drawing a triangle.

Hi Igor,
Thanks for your help. Unfortunately, I do not have much time to dive in the implementation. A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point
What would be a simple piece of code that simply open a cube on the screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.
So, how to show a cube on the screen please?
Cheers, Alexandre

Looks like your machine does not supports them fully, or initialization logic is flawed.. Did you tried to use latest config of NBOpenGL on your machine?
What would be the hello world example in OpenGL in Pharo?
Anything which shows on screen, like drawing a triangle.

It is strange. I checked things lately, NBOpenGL works fine on macs. But i seend that source city code has some modifications. Maybe that is the problem.

Absolutly not
I'm using it on NBCOG VM under windows 8, with an old moose version I guess the problem is not you vm cause you can bind openGL ... Igor ?

Yeah! It works (I guess). I had to use the right VM also.
I obtain the attached screenshot. Apparently the background is not updated. Is this intended in your example?

Thanks for your help. Unfortunately, I do not have much time to dive in the implementation. A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point
What would be a simple piece of code that simply open a cube on the screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.
So, how to show a cube on the screen please?

Seems so.. an opengl buffer is cleared by fully transparent color:
gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT.
then, when resulting image transferred back to Display form, it only changes the pixels which is affected, but fully transparent ones will keep background unchanged. The solution is to use opaque color(s) in opengl buffer, or clear background by morph, before copying pixels from opengl buffer.

Hi guys
I tried to run your hello world example. I first loaded ConfigurationOfSourceCity in a Moose 4.8 development image and tried to run it. Then I loaded it in a Pharo2.0 image and failed the same. I tried to load the image using a NBCog VM (latest).
What am I doing wrong?

Hi !
I manually loaded NBOpenGL from SmalltalkHub and SourceCity on moose 4.8, with the default vm proposed on moose's website and it works. There is a sourcecity and GLTest example.
image.zip : https://www.dropbox.com/s/4v9m5eig7qs4xez/sourcecity.zip vm : http://www.pharo-project.org/pharo-download/release-2-0
I tested it on win 8 64bit. It'll not work on linux. I don't know about mac os. I will update the ConfigurationOfSourceCity, but i have to write my internship's report for the moment.
Sorry for the unexpected troubles

Hi guys
I tried to run your hello world example. I first loaded ConfigurationOfSourceCity in a Moose 4.8 development
image and tried to run it.
Then I loaded it in a Pharo2.0 image and failed the same. I tried to load the image using a NBCog VM (latest).
What am I doing wrong?
Cheers Ricky

Seems so.. an opengl buffer is cleared by fully transparent color: gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT.
then, when resulting image transferred back to Display form, it only changes the pixels which is affected, but fully transparent
ones will keep background unchanged.
The solution is to use opaque color(s) in opengl buffer, or clear background by morph, before copying pixels from opengl buffer.

Thanks for your help. Unfortunately, I do not have much time to dive in the implementation.
A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point
What would be a simple piece of code that simply open a cube on the
screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.
So, how to show a cube on the screen please?

You don't. It just works.
The problem is that different hardware has different features
supported.
During initialization of context i checking + asking for some
capabilities.
Looks like your machine does not supports them fully, or initialization logic is flawed.. Did you tried to use latest config of NBOpenGL on your machine?
What would be the hello world example in OpenGL in Pharo?
Anything which shows on screen, like drawing a triangle.

Hi !
I manually loaded NBOpenGL from SmalltalkHub and SourceCity on moose 4.8, with the default vm proposed on moose's website and it works. There is a sourcecity and GLTest example.
image.zip : https://www.dropbox.com/s/4v9m5eig7qs4xez/sourcecity.zip vm : http://www.pharo-project.org/pharo-download/release-2-0
I tested it on win 8 64bit. It'll not work on linux. I don't know about mac os. I will update the ConfigurationOfSourceCity, but i have to write my internship's report for the moment.
Sorry for the unexpected troubles

Hi guys
I tried to run your hello world example. I first loaded ConfigurationOfSourceCity in a Moose 4.8 development image and tried to run it. Then I loaded it in a Pharo2.0 image and failed the same. I tried to load the image using a NBCog VM (latest).
What am I doing wrong?

Seems so.. an opengl buffer is cleared by fully transparent color: gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT.
then, when resulting image transferred back to Display form, it only changes the pixels which is affected, but fully transparent ones will keep background unchanged. The solution is to use opaque color(s) in opengl buffer, or clear background by morph, before copying pixels from opengl buffer.

Thanks for your help. Unfortunately, I do not have much time to dive in the implementation. A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point
What would be a simple piece of code that simply open a cube on the screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.
So, how to show a cube on the screen please?

You don't. It just works.
The problem is that different hardware has different features supported. During initialization of context i checking + asking for some capabilities. Looks like your machine does not supports them fully, or initialization logic is flawed.. Did you tried to use latest config of NBOpenGL on your machine?

Anything which shows on screen, like drawing a triangle.

Really strange. I made it work on my macbook air by trying out different combination. I have an error (about the platform Id) when I follow Erwan instruction.
Getting OpenGL working from Pharo is not easy apparently.
I am using OSX 10.8.3 for both my desktop and my laptop.

Thanks Igor.
In the code:
gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT.
I have changed the 0 for 0.5 or 1 and it works as expected. 0 is apparently for full transparency, so the behavior I got is rather normal. Although it is strange I am the only one to experience this.
Cheers, Alexandre

I obtain the attached screenshot. Apparently the background is not updated. Is this intended in your example?
Seems so.. an opengl buffer is cleared by fully transparent color: gl clearColor_red: 1 green: 1 blue: 1 alpha: 0; clear: GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT.
then, when resulting image transferred back to Display form, it only changes the pixels which is affected, but fully transparent ones will keep background unchanged. The solution is to use opaque color(s) in opengl buffer, or clear background by morph, before copying pixels from opengl buffer.

2013/6/4 Alexandre Bergel alexandre.bergel@me.com Hi Igor,
Thanks for your help. Unfortunately, I do not have much time to dive in the implementation. A student is asking me how he can use OpenGL in Pharo. I would like to give him a simple starting point
What would be a simple piece of code that simply open a cube on the screen? I cannot ask him to go and study SourceCity or the implementation of NBOpenGL. He barely knows Smalltalk but he is very smart.
So, how to show a cube on the screen please?
Cheers, Alexandre

You don't. It just works.
The problem is that different hardware has different features supported. During initialization of context i checking + asking for some capabilities. Looks like your machine does not supports them fully, or initialization logic is flawed.. Did you tried to use latest config of NBOpenGL on your machine?
What would be the hello world example in OpenGL in Pharo?
Anything which shows on screen, like drawing a triangle.
Cheers, Alexandre

It is strange. I checked things lately, NBOpenGL works fine on macs. But i seend that source city code has some modifications. Maybe that is the problem.
