Re: [geomview-users] geomview builds again from cvs

[Claus-Justus H. <cl...@ma...>]

There are also some other new features:

* working transparency (translucency) with OpenGL by means of BSP-trees. 
To be precise: single objects -- as listed in the browser in the main 
panel -- will be rendered correctly with respect to themselves and with 
respect to any number of other solid objects. Translucent objects can be 
complex: lists and insts will work. This is new and still somewhat 
experimental; maybe I will turn the BSP-tree stuff into an optional 
feature which has to be activated at configure-time 
(--enable-bsptree-translucency or so).

* I tried to reenable the OSMesa snapshots (OS == Off Screen), but with 
no luck. However, by means of glXCreateGLXPixmap() it is possible to 
render into off-screen memory, and this works now. On-Screen snapshots 
always suffer from the problem that the window has to be mapped and not 
obscured by other windows. Which also means that activating a 
screen-saver might be a problem. GLX offscreen snapshots can be actived with

(snapshot CAMID ppmosglx XSIZE ZSIZE)

and using the File->Save menu.
