The LoadingManager also has an onProgress property 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. Perhaps by disabling the interface effect when hovering over a link? Theres no way in the shader to do something like every 4 quads since its a post process effect. The offset is here to calculate the distance between the center of the screen and the object on the page. I know its kinda frustrating but the main purpose of this demo was to show hovers with shaders plus some transitions on click. If youre interested, be sure to read this page from The Book of Shaders.

Because of the coordinate system in shaders. Find centralized, trusted content and collaborate around the technologies you use most. For setting the filter when the texture is drawn larger than its original size For the moment, we set a MeshBasicMaterial, just to see if everything is fine. and pass it to the TextureLoader then set its onLoad less memory than a PNG in WebGL. are offset with units where 1 unit = 1 texture size. A little bummed that this doesnt explain the really great cursor/hover effect with the RGBA channel separation. First, we create another class where we pass the scene as a property. larger than its original size and what happens when it's drawn smaller than its Sync the movements, Move the unsticky part to the destination while not moving the sticky part. For example, we only need to increment when we are hovering the figure, not every frame. If you have any questions, let me know in the comments section! If we multiply its value, it will be more contrasted.
