Shaders can read information from these images and write information to them, in ways that they cannot with textures. This can allow for a number of powerful features ...
WebThe Gather Texture 2D node samples the red channel of four neighboring pixels from a sample point. It returns a value of RRRR, and takes each R value from a different neighbor. Normal Texture sampling reads all four channels (RGBA) of a Texture. This node is useful when you want to modify the bilinear interpolation between pixels, such as when ...
