WebThe depth buffer precision in eye coordinates is strongly affected by the ratio of zFar to zNear, the zFar clipping plane, and how far an object is from the zNear clipping plane. You need to do whatever you can to push the zNear clipping plane out and pull the zFar plane in as much as possible. To be more specific, consider the transformation ...

"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 " - Opengles depth test

WebOpenGL Rendering Pipeline. A Fragment Shader is the Shader stage that will process a Fragment generated by the Rasterization into a set of colors and a single depth value. The fragment shader is the OpenGL pipeline stage after a primitive is rasterized. For each sample of the pixels covered by a primitive, a "fragment" is generated. Web三、使用多个纹理单元. 一个纹理单元能支持多个纹理绑定到不同的目标，一个程序中也可以使用多个纹理单元加载多个2D纹理。. 最终值得计算方法为：x× (1−a)+y×a。. mixValue通过程序传递，可以通过键盘上的A和S键，调整纹理混合值，改变混合效果。.
