I am trying to understand derivative computation in TextureSystem. Why I derivatives scald by the image width and height?
For example: simd::float4 scalex = weight_simd * float(spec.width); simd::float4 scaley = weight_simd * float(spec.height); Why is there this scaling factor? _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
