The Z-buffer algorithm is a convenient algorithm for rendering images properly according to depth. To begin with, a buffer containing the closest depth at each pixel location is created parallel to the image buffer. Each location in this depth buffer is initialized to negative infinity. Now, the zIntersect and dzPerScanline fields are added to each edge record in the polyfill algorithm. For each point that is to be rendered, the depth of the point against the depth of the point at the desired pixel location. If the point depth is greater than the depth at the current pixel, the pixel is colored with the new color and the depth buffer is updated. Otherwise, the point is not rendered because it is behind another object.

What is the Difference between frame buffer and z buffer?

The z-buffer holds information about the depth of a 3D scene. Specifically, it holds information about the coordinates of each object in the scene, so that the CPU/GPU knows the order in which objects should be drawn.The frame buffer is a more physical thing. Your computer monitor stores information for the next image it's going to draw in the frame buffer.

How buffer concentration effects on retention time in hplc method?

Buffer concentration can affect retention time in HPLC by influencing the pH of the mobile phase, which can in turn impact interactions between the analyte and stationary phase. Higher buffer concentrations can alter the ionization state of the analyte, leading to changes in its retention time. Additionally, buffer concentrations can also affect peak shape and resolution in the chromatogram.

What is the method to calculate the pH of a buffer solution?

To calculate the pH of a buffer solution, you can use the Henderson-Hasselbalch equation, which is pH pKa log(A-/HA), where pKa is the negative logarithm of the acid dissociation constant, A- is the concentration of the conjugate base, and HA is the concentration of the weak acid in the buffer solution.

What is frame buffer size formula?

it would be [X * Y * color depth(in bits)] this would give you the the frame buffer size in bits. Example: Say we had a resolution of 1280 x 1024 and a color depth of 4 bits. we would go 1280 * 1024 * 4 to give us 5242880 bits then to get bytes we divide by 8 to get 655360 bytes then to get kilobytes we divide by 1024 (Remember computers are base 2) 640 kilobytes so a computer running at 1280 x 1025 with a color depth of 4 bits requires a frame buffer of 640 kilobytes.
