hi list, i want to use a closed cylinder. so i made an abstraction cylinder_closed.pd. but it seems not to be very fast and it can't be used with [repeat n]. is there a better way to approach this?

attached is a version that is both [repeat]able and fast,

hi IOhannes, thanks for your help, i think you forgot to attach the patch?

but unfortunately it won't run on your system ;-)

but i guess using the cvs-gem it would run?

your patch is so slow, because both [cylinder] and [disk] are slow (because they don't use display-lists), so you cannot gain much speed that way. chris clepper kept stating that we need a mechanism to allow the user to build their own display-lists to speed things up. i always thought that this could be done with the openGL-wrapper-objects, but appearantly 2 crucial objects were missing [GEMglNewList] and [GEMglEndList]; i have added them to the CVS now (and used them already in the patch ;-)) so what i have done in the patch is create a display-list of the closed cyclinder and call that instead of the objects.

so my patch is another good example of what the openGL-wrapper is for and how to use it.

i'll try to learn as much as i can about it...

within the ccylinder-abstraction there is a solitaire subpatch [pd closedcylinder] which does not depend on the openGL-wrapper at all. it is still slow, but you can use it as a normal Gem-object (e.g. with [repeat])

danke.
