JOGL mipmaps 和纹理闪烁
我的 OpenGL 2 场景中有一面墙和一块砖纹理，无论我设置什么，它们都会持续闪烁。当我放大近距离（并且可以清楚地看到纹理）时，闪烁和闪烁就会停止。但是当我缩小并在场景中移动时，闪烁和闪烁非常明显。这是砖墙的纹理代码：
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_WRAP_S, GL2.GL_REPEAT);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_WRAP_T, GL2.GL_REPEAT);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_MAG_FILTER,GL2.GL_NEAREST);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_MIN_FILTER,GL2.GL_LINEAR);
gl.glGenerateMipmap(GL2.GL_TEXTURE_2D);
brickwall.enable(gl);
brickwall.bind(gl);
//...
brickwall.disable(gl);
从我用谷歌搜索到的内容来看，这似乎是 mipmapping 解决的问题。但我的问题是，如何做到这一点？我是否必须为所有 2 倍大小的图像创建、加载和设置参数？谁能给我一个使用 mipmap 加载和显示 JOGL2 纹理的示例，该纹理在场景中缩放和移动时不会闪烁和闪烁？
I've a wall and a brick texture in my OpenGL 2 scene that keeps shimmering and flashing no matter what I set. When I'm zoomed in close (and can see clearly the texture), then the flashing and shimmering stops. But when I'm zoomed out and moving around the scene, the flashing and shimmering is very pronounced. This is the texture code for the brick wall:
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_WRAP_S, GL2.GL_REPEAT);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_WRAP_T, GL2.GL_REPEAT);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_MAG_FILTER,GL2.GL_NEAREST);
brickwall.setTexParameteri(gl, GL2.GL_TEXTURE_MIN_FILTER,GL2.GL_LINEAR);
gl.glGenerateMipmap(GL2.GL_TEXTURE_2D);
brickwall.enable(gl);
brickwall.bind(gl);
//...
brickwall.disable(gl);
From what I've googled, it seems that this is a problem that mipmapping solves. But my question is, how does one do this? Do I have to create, load and set parameters for all the various power of 2 sized images? Can anyone give me an example for loading and displaying a JOGL2 texture using mipmaps that won't flicker and shimmer zooming and moving about a scene?

您正在使用 glGenerateMipmap 生成 mipmap 链，但没有设置适当的 MIN 过滤器：
*MIPMAP* 过滤器使用 mipmap，而其他纹理过滤器则不使用。
You are generating the mipmap chain with glGenerateMipmap, but you didn't set an appropiate MIN filter:
The *MIPMAP* filters use mipmaps, the other texture filters don't.
