Re: [Pharo-users] Polygons + Skybox in woden?

by Lusa Nicolas

Thanks Ronie this is what I was looking for! Amazing going to try it out today and see how it works. For what concern polygons I knew about the algorithms (thanks for mentioning them anyway), was just looking for a "more straight forward" solution since rendering polygons isn't the main goal of my thesis which means I have others priorities. Thanks again, cheers. Nicolas On Apr 20, 2015, at 7:56 AM, Ronie Salgado <roniesalg(a)gmail.com<mailto:roniesalg@gmail.com>> wrote: I have just added a simple skybox support.

Question2: How could I use GL_POLYGON through woden for my purpose? Moreover, I would like to put some sort of skybox in my scene. Apparently it's not possible yet, so my question is how could I do that? Thanks in advance. Cheers. Nicolas

Re: [Pharo-users] SDL2 and fork

by Matthieu Lacaton

Hello, Thanks for your answers ! I have multiple remarks here : 1) I know that SDL2 should not be used "as is" in Pharo and I should use OSWindow instead, that's why I won't use SDL2 directly anymore. 2) But for the moment OSWindow uses SDL2 anyway so for experimentation purposes I will try to see what's wrong with my code. The example you linked Nicolai is working indeed and this is more or less what I did too. I included my code with this e-mail so maybe you can have a better understanding (I am sorry but I didn't comment it :s). Note that for it to work you need to add the SDL_image library and all its plugins (for handling jpeg, png etc.) and add the following method to the image : SDL_Renderer >> createTextureFromFile: file <primitive: #primitiveNativeCall module: #NativeBoostPlugin error: errorCode> ^ self nbCall: #( SDL_Texture IMG_LoadTexture ( self , String file ) ) module: 'SDL_Image.dll' You can launch the game by executing "MyGame new startGame" On my computer (which is probably not the fastest I must admit) running it with a fork slows the whole operating system. 3) Another problem I had lately : I tried to use Pharo with linux (ubuntu 14.04.2 LTS) and Pharo just can't find the SDL library. I downloaded SDL source code and compiled it so i got the libSDL2-2.0.so.0.2.1 exactly as in the SDL2 class >> findSDL2 method. I tried to put it everywhere (in the "shared" and "bin" folder of Pharo and even at the root. I tried in /usr/lib/, in /usr/lib32/, in /usr/lib/x86_64-linux-gnu etc. and Pharo can never find it. Could it be that I compiled it for 64bits (my ubuntu is 64 bits) and Pharo does not support it so I should recompile it for 32 bits ? Thanks you all !

Well, this is exactly what I needed, Great examples too, HTML and LaTeX format tried and worked fine. PS: Pharo didn't know PRCocoonConfiguration class at first (bad version of Pillar I guess), but this version of Pillar loaded into pharo helped.
