Hi,

Sorry if anyone feels it's inappropriate to put all this in one thread. I just want to clarify some bugs / missing features / misunderstandings on my part, in gem (0.90 winXP)


1. Is it currently possible to set light direction, beam width and attenuation rate properties?

2. There appears to be a bug with disabling lights (either by sending a 'zero' message to the gemhead, or physically deleting a connection in the gemlist by hand); they continue to affect the lighting of the scene, in a fairly similar way to if the gemhead render order value was negative (hope that is clear).

3. pix_video with my phillips webcam crashes the program.... I did have a version of this that worked (from a CVS build a while ago, ca. 0.87? 0.84?) on an old(er) machine. I may be able to retrieve it, the harddisk it was on crashed. I will post again if I have any luck with this.

I think that's all for now (and there's plenty I can be getting along with with GEM as it is - nice piece of work). Thanks in advance,

Peter

OK, I looked back at the tuorial patches and realised lights can be controlled with 1/0 messages to the light object itself (I guess disabling the gemhead too will cut out some unnecessary calculations).

pter,
have you had any luck getting pix_video to work? it crashes pd on me too. let me know if you figure anything out.

Yes, this was discussed on the mailing list a bit, and there is a new version of GEM (0.90.1 or something) which fixes it for me and other people. I think it's the version on the main GEM IEM page now, not sure.
