norm & snorm for jit.expr
The help file for jit.expr says:
- norm[0-31] (normalized coordinate across dim);
- snorm[0-31] (signed normalized coordinate across dim).
But I don't quite understand what they means.
Could someone help explain further ?
Thanks.
norm[0] will spread a gradient from 0 to 1 across the x axis
norm[1] will spread a gradient from 0 to 1 across the y axis
snorm[0] will spread a gradient from -1 to 1 across the x axis
snorm[1] will spread a gradient from -1 to 1 across the y axis
Thank you very much.
