Web16 de mai. de 2024 · In OpenGL, all depth values lie in the range [0, 1]. The integer normalization process simply converts this floating-point range into integer values of the appropriate precision. It is the integer value that is stored in the depth buffer. Typically, 24-bit depth buffers will pad each depth value out to 32-bits, so 8-bits per pixel will go unused. Web13 de mar. de 2024 · 在OpenGL中，深度测试通过开启深度缓冲区来实现。在绘制每个像素时，OpenGL会将像素的深度值与深度缓冲区中的值进行比较，如果像素的深度值比缓冲区中的值小，就更新深度缓冲区，并绘制该像素。在OpenGL中，可以使用glEnable(GL_DEPTH_TEST)来开启深度测试。
