Unfortunately there are not so much detailed materials about grvecs fumction on the net. Tbh I don't even know what does it do because if I try out the example in the official documentaton it doesnt seem to work. 😄 So I don't know what does "vector" mean in this case. So what's the difference between this and grdraw for example.
So I think it would be useful to collect here some working lisps that utilizing grvecs function.
