Video Chat App Showcase
This is a small demonstration of a project that can be used video chat. It uses Socket.io and PeerJs (WebRTC) to send and receive webcam streams across the clients.
Computer Graphics - Depth Buffer Test
Depth Buffer (Z-buffer) Test Algorithm The following algorithm is taken from here . We start with setting the depth of each pixel to infinity. d(i, j) = infinity Initialize the color value for each pixel c(i, j) = background color for each polygon, do the following steps : for (each pixel in polygon's projection) { z (depth) of polygon at (x, y) corresponding to pixel (i, j) if (z < d(i, j)) { d(i, j) = z; c(i, j) = color; } } Example Figure An example taken from METU CENG Slides Z-Fighting Z-fighting occurs when two planes have the same depth (have the same value in the z-axis) and z-buffer cannot decide which plane is near which one is far. Then the following situation occurs: Z-fighting in the intersection This situation may occur also when the depth range [nearest, furthest] is scaled to [0,1]. This is range [0,1] scaling from [near=10, far=50] after projection and viewport transformations. T...
