I’m attempting to recreate a 3D pixel artwork water impact the place white horizontal strains are proven by means of the floor and disappear/reappear slowly. You may see a video of this impact right here
This video is from An even bigger weblog publish It particulars a variety of visible results of 3D pixels, and right here it’s proven that white strains will not be a part of one thing like a particle system and likewise present a texture they use to manage the dimensions, place and orientation of white strains.
They actually don’t clarify anymore, however my greatest assumption about how this impact works is that they proceed a grid on water within the coordinates of the imaginative and prescient area after which use the feel as a masks (the alpha channel of the feel encodes the gap from the middle to the sting of every voronoi cell). Maybe the RG channels of the feel are even used as UV coordinates, since they appear to be counting positional information. I additionally say process, as a result of the video that may clearly see that the strains at all times have 1 pixel broad, which I believe can be troublesome to realize with only a texture.
How can I procedurally draw a grid or strains and ensure that I at all times have 1 pixel broad? I’m utilizing spelling projection because the video, so the angle shouldn’t be an element. Additionally it is essential that the road shouldn’t be anti-alias, to protect the aesthetics of pixels artwork.
