Hi all, I always have a long term plan for pcb-rnd and Ringdove. On this long term plan there's the polygon lib rewrite, which (unfortunately) needs to wait a bit, the queue is full with miniboxtk, librnd 4.0.0 and sch-rnd 1.0.0 preparations now. However, I occassinally do some research in advance. One of the things I could do during the polygon lib rewrite is experimetning with running some of the code on GPU. This turned out to be much more complicated than I thought because of utterly badly designed APIs (if anyone is interested I can share details). Long story short, there are two ways doing this, one is a real hackish thing (gpgpu techniques) that would potentially work on any opengl 3.2+ capable GPU+dirver combo and the "nice, clean" way (opencl) that works only on some video cards that have specific features for it. Those who know me probably also know I don't normally use 3d hardware and I hate opengl. I still have a few video cards, things others threw out because of obsolence. I digged through them, a few cards, a few laptops, and it turned out none of them has the feature required by opencl. So, if you have some old (but working and has opencl support) video card that you can't use for anything, but don't want to throw away and can't sell, you could maybe donate it for this subproject. It doesn't have to be fast or fancy, I'm after the API, not after performance. My other problem is that I don't have a mobo with pci-e slot; so same story: if you have a too-old-to-use mobo+CPU+ram combo that already has PCI-E, please consider donating. It's neither urgent nor critical. TIA, Igor2
