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 Web2 de ago. de 2012 · OpenGL中alpha测试GL_ALPHA_TEST. 我们知道像素的Alpha值可以用于混合操作。. 其实Alpha值还有一个用途，这就是Alpha测试。. 当每个像素即将绘制时，如果启动了Alpha测试，OpenGL会检查像素的Alpha值，只有Alpha值满足条件的像素才会进行绘制（严格的说，满足条件的像素会 ...

WebGL_DEPTH_COMPONENT. Each element is a single depth value. The GL converts it to floating point, and clamps to the range [0,1]. GL_DEPTH_STENCIL. Each element is a pair of depth and stencil values. The depth component of the pair is interpreted as in GL_DEPTH_COMPONENT. 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.
