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 ... Web我想了想似乎能说通,一个像素如果EarlyZ没过,那自然被抛弃,无影响;如果EarlyZ和AlphaTest都通过了,不写深度,也就frag写入颜色,没毛病;重点是如果EarlyZ过了但是AlphaTest没过,那这个像素不会对FrameBuffer产生任何影响(前提是Early Depth/Stencil Test过程不写模板),所以也没毛病,合理。

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 WebGame developers can combat overdraw by enabling depth testing and submitting opaque draws from front to back. This enables GPUs to perform depth tests early in the GPU pipeline then reject fragments from the additional pipeline stages if they are obscured by a primitive previously coloured at that fragment location.
