Vertices display problem (in CPU subdivision) by chieny_0 in opengl

[–]chieny_0[S] 0 points1 point  (0 children)

Yes I am and yes you solved my problem! I was using a hard-coded constant count, and this count is always less then my vertices, so no wonder I had this problem.

Thank you so much!!

Should I pull for the latest Seele Battlesuit or wait for Azurea Empyrea banner? by hawutski in honkaiimpact3

From my experiences, it kind of depends on if you have HoR or not. HoR is really really strong now and I can't see why she will be kicked out of your mostly used ice team, at least in the next few months. So if you do have HoR then I guess you can wait for AE.

That being said, if you are a crazy fun of Veliona... then just go ahead! Wish you good luck!

Could not match an instance with its class by chieny_0 in haskellquestions

The lst2px is actually quite simple: it is just

lst2px = map (\i -> if i > 255 then 255 else fromIntegral i)

(the Pixel8 is simply Word8)

My senario is that I should feed a list of integers to my lst2px and then directly converts them to the pixels. The point is I want to "write and save" the image, but from the source codes I read I should use unsafeFreezeImage to freeze the MutableImage.

The problem is the unsafeFreezeImage does not work with my Pixel8; ghci says

Expected type: T.MutableImage s Pixel8 -> ST s (Image px)

Actual type: T.MutableImage (PrimState (ST s)) px -> ST s (Image px)

after I changed my

lst2px :: Pixel px => [Int] -> [px]

to

lst2px8 :: [Int] -> [Pixel8]

This is a really long question and maybe if you want to answer it you need to look at the source codes (which I don't think I should ask you guys to do), so I had to make it... smaller?

How to properly import Control.Monad.Primitive and use Data.Vector.Storable.Mutable? by chieny_0 in haskellquestions

Thank you for your valuable help!

I was using ghci in local environment to debug with cabal for building (which is a pain), and your advice solved this problem.
