WebThe hidden surface removal method provides a solution to the visibility problem, which was one of the first major problems in the 3D graphics field. Hidden surface determination is necessary to render an image correctly, so that one could not look through the walls in virtual reality. Object Space Method: It is implemented in the World ...
Web25 de ago. de 2011 · In many cases, 3d hidden surface removal means that when you draw a surface, you also remember the depth of each pixel that you draw (distance from the 'eye'). When you go to draw a surface where a surface has already been drawn, you only draw the pixel if it's closer to the eye than the pixel that's already there. Web18 de jan. de 2012 · The most common technique I found to perform object-space hidden surface removal is to use a BSP tree, which in theory works just fine. So I implemented that, but performance wasn't even remotely acceptable, which isn't entirely surprising given its O (n 2) complexity. The test scene I'm using has about 4800 triangles after backface …
