Web2 de ago. de 2012 · glEnable(GL_DEPTH_TEST)： 用来开启更新深度缓冲区的功能，也就是，如果通过比较后深度值发生变化了，会进行更新深度缓冲区的操作。启动它，OpenGL就可以跟踪再Z轴上的像素，这样，它只会再那个像素前方没有东西时，才会绘画这个像素。在做绘画3D时，这个功能最好启动，视觉效果比较真实。 OpenGL allows us to modify the comparison operators it uses for the depth test. This allows us to control when OpenGL should pass or discard fragments and when to update the depth buffer. We can set the comparison operator (or depth function) by calling glDepthFunc: The function accepts several comparison … Ver mais The depth buffer contains depth values between 0.0 and 1.0 and it compares its content with the z-values of all the objects in the scene as seen … Ver mais We know that the z-value of the built-in gl_FragCoordvector in the fragment shader contains the depth value of that particular fragment. If we were to output this depth value of the … Ver mais A common visual artifact may occur when two planes or triangles are so closely aligned to each other that the depth buffer does not have enough precision to figure out which one of the … Ver mais

WebDepth Testing • Depth testing is an effective technique for hidden surface removal, and OpenGL has functions that do this behind the scenes. • This maneuver is accomplished internally by a depth buffer with storage for a depth value for every pixel on the screen. 7 1.When a pixel is drawn, it is assigned a value Web19 de fev. de 2010 · We do not draw GL_POLYGONs, but we draw triangles and on some systems the smooth also causes effects on triangle edges which should not be smooth. That’s evil right there. Well, evil’s a strong word, I guess. Anytime you’re drawing triangle (even using GL_POLYGON they end up being rasterized as triangles usually) you don’t …
