createTexture :: forall m t. (MonadIO m, MonadResource m, Texture t) => TextureSize t -> Natural -> Sampling -> m t Source
'createTexture w h levels sampling' a new 'w'*'h' texture with levels
levels. The format is
set through the type.
Sampling
A sampling configuration type.

Fields |
defaultSampling :: Sampling Source
Default Sampling
for convenience.
defaultSampling = Sampling { samplingWrapS = ClampToEdge , samplingWrapT = ClampToEdge , samplingWrapR = ClampToEdge , samplingMinFilter = Linear , samplingMagFilter = Linear , samplingCompareFunction = Nothing }
Texture sampler customization
Wrap texture parameter. Such an object is used to tell how to sampling is performed when going out of the texture coordinates.
ClampToEdge
will clamp the texture coordinates between in '[0,1]'. If you pass '1.1' or
'31.456', in both cases you’ll end up with '1'. Same thing for negative values clamped to '0'.
Repeat
will clamp the texture in '[0,1]' after applying a fract
on the value, yielding a
a repeated '[0,1]' pattern.
