What are the different types of visible surface detection?

Scan-Line Method It is an image-space method to identify visible surface. This method has a depth information for only single scan-line. In order to require one scan-line of depth values, we must group and process all polygons intersecting a given scan-line at the same time before processing the next scan-line.

Which is a visible surface detection algorithm?

The identification and removal of these surfaces is called Hidden-surface problem. In this paper I review some visible surface detection algorithms like Z buffer method, Area subdivision method, Scan line method etc. Keywords— Visible surface detection algorithms, Z buffer, Area subdivision, Scan line method etc.

What is surface identification?

 When a 3D object need to be displayed on the 2D screen, the parts of the screen that are visible from the chosen viewing position is identified.  Algorithms to detect visible objects are referred to as visible-surface detection method.

Where can I find visible surface detection methods?

You can also find Visible Surface Detection Methods – Computer Graphics (CG) Computer Science Engineering (CSE) Notes | EduRev ppt and other Computer Science Engineering (CSE) slides as well.

How to use CG for visible surface detection?

Computer Science Engineering (CSE) Visible Surface Detection Methods – Computer Graphics (CG) Summary and Exercise are very important for perfect preparation. You can see some Visible Surface Detection Methods – Computer Graphics (CG) sample questions with examples at the bottom of this page.

How is visibility detection used in computer graphics?

The extension of depth-buffer method is A-Buffer method. For rendering the Renders Everything You Ever Saw (REYES), the visibility detection method developed is A-buffer method. Transparency is provided by A-buffer method. The accumulated buffer is the key data structure for the A-buffer method.

How are hidden surface problems solved in computer graphics?

The hidden surface problems can be solved by two methods − Object-Space method and Image-space method. In physical coordinate system, object-space method is implemented and in case of screen coordinate system, image-space method is implemented.
