WebIncluded Effects The total demo download size is about 60 MB. less memory. tex2.r = texture2D(u_texture2, centeredAspectRatio(uv, u_textureFactor )).r; Since the corners are the farthest away from the center, they end up being most sticky. With this simple observation we can extrapolate some of the things we need to do: Differentiate between the unsticky part of the image which is going to move normally and the sticky part of the image which is going to start with an offset. This has the big advantage that we don't have to wait for the texture to load and our three.js We specialize in Website Design, Web Hosting, App Development (Apple and Android) and Custom Application Development. This is a trade-off between hardware support, efficiency and quality since linear results normally require at least 12 bits per color channel to prevent color degradation and banding.
