WebScan Line Algorithm. Idea is to intersect each polygon with a particular scanline. Solve hidden surface problem for just that scan line. Requires a depth buffer equal to only one scan line ; Maintain an active polygon and active edge list ; Can implement antialiasing as part of the algorithm; 13 BSP Trees . Binary Space Paritition is a ... WebA scan line method of hidden surface removal is an another approach of image space method. It is an extension of the scan line algorithm for filling polygon interiors. Here, the …

Computer Graphics Scan Line Algorithm - javatpoint
WebA hidden surface determination algorithm is a solution to the visibility problem, which was one of the first major problems in the field of 3D computer graphics. The process of hidden surface determination is sometimes called hiding, and such an algorithm is sometimes called a hider. The analogue for line rendering is hidden line removal. WebAug 7, 2015 · Two main Hidden Surface Removal Algorithm Techniques: Object space: Hidden Surface Removal for all objects Image space: Objects: 3 D Clipping Transformed to Screen Coordinates Hidden Surface Removal. 5.
