Now that I finally have some level of hardware 3D acceleration working at all on my linux computer, Istarted to look at wheather Squeak is able to access it.
I am on windows and never had a Linux, but I will try my best to share my experience.
Attempting to toggle hardware acceleration with the menu checkbox was ineffectual.
I think that "menu checkbox" means the item on the top left of the B3DSceneExplorerMorph. That checkbox is labelled "Enable hardware acceleration". Right? On Squeak for Windows, we have a menu item (in the window menu) "VM preferences" and a submenu "Display and Sound" with three items. It is important to check "Use OpenGL (instead of D3D)" Hardware acceleration needs OpenGL; it will not work when you use D3D.
When you try Hardware acceleration with the rotating cube, the effect is not very impressive (IMHO). For more complicated scenes, I found hardware acceleration more impressive. When you use hardware acceleration on a Windows PC, the colors of the scene change, this is a well-known bug, but also an indication that hw acceleration works.
Now I have these questions:
- On what platforms is hardware 3D acceleration supported?
You need an OpenGL driver. Most modern operating systems have one, but if you need one, you will find it on http://www.opengl.org/
