What do you mean with "modern"?

By modern I mean a graphics card a with graphics driver that supports at least OpenGL 4.x. That Intel HD graphics card is capable of supporting at least OpenGL 4.2, but the Open Source Mesa driver gives you support up until OpenGL 3.1. Unfortunately, unlike with AMD or NVIDIA graphics cards, the open source driver is the official driver.

Woden-Roassal requires integer arithmetic in shaders which is used to support the selection of objects. Integer arithmetics in shaders requires at least OpenGL 3.3, or the missing extension for which you are receiving the error.

It is not required by the Woden-Core api, so you should be able to try the following in a workspace:

My notebook with an HD Graphics 4400 has no problems with all "three.js" demos found here http://threejs.org/.

Three.js or any WebGL based example is a bad test for that graphics card. WebGL is based in OpenGL ES 2.0 which is a subset of OpenGL 2.0. This is a very old technology for that graphics card.

Woden will be using Vulkan in the future. According to this Phoronix article (http://www.phoronix.com/scan.php?page=news_item&px=LunarG-Vulkan-AMA), Valve has already made a proper Vulkan driver for the Intel graphics cards. We only need an official release of the Vulkan spec.

You need a modern graphics card. Open source graphics drivers are not supported because there are very behind in their implementations of OpenGL.

Woden works in Pharo 5.0

I have just tried.

Do we have a tutorial? i found only http://woden.ronie.cl.

What about mouse control and object selection. It that possible?

Yes.��

To load Woden:

Gofer new smalltalkhubUser: 'ronsaldo' project: 'Woden'; package: 'ConfigurationOfWoden'; load. (Smalltalk at: #ConfigurationOfWoden) loadBleedingEdge.

Try:

=-=-=-==-=-=-==-=-=-==-=-=-=

v := RWView new.

1 to: 100 do: [ :i |

e := RWCube element.

e when: RWMouseButtonDown do: [ :ev |

ev element shape color: WDColor green.

ev element changed.

].

v add: e.

].

RWXZGridLayout on: v elements.

v addInteraction: RWMouseKeyControl.

v camera position: (WDVector3 x: 0.0 y: 0.0 z: 3.0).

v open

Use the keys A S D W and the moose to navigate. Click on cube to make them green

its possible via my Ephestos project, to render to video or real time but the project is still very much a WIP. Its doable but require some python knowledge and knowledge of Blender UI and API. I will be making a true Pharo API for it fairly soon but as you can imagine these things take time.
