- 3. Understanding the Z-BufferAlgorithm. This presentation will provide an overview of the Z-buffer algorithm, a popular algorithm used in computer graphics for rendering 3D scenes in real-time. It will explore how the algorithm works, its advantages and disadvantages, and how it can be used in various applications.
- 4. Overview of theAlgorithm - Used to determine which objects in a scene are visible and which are hidden. - Keeps track of the depth of each pixel in the scene as it is rendered.
- 5. How the Algorithm Works? Comparesdepth of new object to depth of existing pixel in the buffer. - If depth of new object is closer, it is drawn and depth is updated. - If depth of new object is further away, it is hidden and not drawn.
- 6. ADVANTAGES Simple toimplement and highly efficient Any kind of opaque surface can be handled/removed. Well-suited for real-time rendering applications like video games. It displays complex surface intersections easily.
- 7. DISADVANTAGES Can requirea large amount of memory, especially for high-resolution displays. It is a time-consuming process as it needs to scan and convert every polygon. Since depth storing is not done, a location in the z-buffer may have to be changed many times depending on the number of surfaces representing the scene.
- 8. Applications: The Z-bufferis a technology used in almost all contemporary computers, laptops, and mobile phones for performing 3D computer graphics. Used in computer graphics for rendering 3D scenes in real-time. The primary use now is for video games, which require fast and accurate processing of 3D scenes. The Z-buffer is implemented in hardware within consumer graphics cards.
