My image doesn't appear. What is going on? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

Normally images have to be texture-mapped onto Geos. You have to use ![pix_texture] to map the current image onto a Geo. "Current" means that any pix-manipulation that is done after texturing will ...

![pix_draw] is almost never hardware accelerated on PCs graphics accelerator. This means that it runs extremely slowly.

How can I optimize my patches? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

One of the biggest performance hits is having UI elements in your patch which have to be updated.

How do I get audio data to GEM? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

One simple way to get raw audio values right now is to use ![snapshot~]. Just set up a metro which bangs ![snapshot~] and use the floating point value.

Why do I get clicks in the audio? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

If you are getting a constant stream of clicks in your audio, then it is probably because you are trying to do graphics and audio in the same process.

Why can't GEM find an image/model file? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

This means that GEM can't locate the file. If you use an absolute path (with / for instance), then GEM will look there. Otherwise, GEM will look in the directory of where the patch is. Then pd/GEM ...

Why doesn't <object> exist on <platform>? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

Usually, this is because I don't have the resources to get the object running on that platform. If an object that you want doesn't exist on your platform, then ask for it! However, if it is tied to ...

Basically, I don't have physical access to an SGI machine.

Set the environment variable

Why doesn't gemorb work? by IOhannes m zmoelnig — last modified 2006-12-20 12:40 PM

You need to make sure that your !SpaceOrb is hooked up correctly. I am using a library which isn't supported by !SpaceTec so there can be problems, although I have not had any.
