java - openGL/JOGL : Why do some Textures render "Smoothed" and some not?

Question

下面的代码是在我的JOGL练习应用中渲染单个立方体的方法:

        public void render(GL gl)
        {
            texture.enable();

            gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MAG_FILTER, GL.GL_NEAREST);

            texture.bind(); // textures clockwise from top left when
            // facing

            gl.glBegin(GL.GL_QUADS);

            // north facing side
            if (renderSide[0])
                {
                    gl.glNormal3i(0, 1, 0);
                    gl.glTexCoord2f(0.0f, 0.0f);
                    gl.glVertex3fv(v2, 0);
                    gl.glTexCoord2f(1.0f, 0.0f);
                    gl.glVertex3fv(v1, 0);
                    gl.glTexCoord2f(1.0f, 1.0f);
                    gl.glVertex3fv(v5, 0);
                    gl.glTexCoord2f(0.0f, 1.0f);
                    gl.glVertex3fv(v6, 0);
                }
            // east facing side
            if (renderSide[1])
                {
                    gl.glNormal3i(1, 0, 0);
                    gl.glTexCoord2f(0.0f, 0.0f);
                    gl.glVertex3fv(v3, 0);
                    gl.glTexCoord2f(1.0f, 0.0f);
                    gl.glVertex3fv(v2, 0);
                    gl.glTexCoord2f(1.0f, 1.0f);
                    gl.glVertex3fv(v6, 0);
                    gl.glTexCoord2f(0.0f, 1.0f);
                    gl.glVertex3fv(v7, 0);
                }
            // south facing side
            if (renderSide[2])
                {
                    gl.glNormal3i(0, -1, 0);
                    gl.glTexCoord2f(0.0f, 0.0f);
                    gl.glVertex3fv(v4, 0);
                    gl.glTexCoord2f(1.0f, 0.0f);
                    gl.glVertex3fv(v3, 0);
                    gl.glTexCoord2f(1.0f, 1.0f);
                    gl.glVertex3fv(v7, 0);
                    gl.glTexCoord2f(0.0f, 1.0f);
                    gl.glVertex3fv(v8, 0);
                }
            // west facing side
            if (renderSide[3])
                {
                    gl.glNormal3i(-1, 0, 0);
                    gl.glTexCoord2f(0.0f, 0.0f);
                    gl.glVertex3fv(v1, 0);
                    gl.glTexCoord2f(1.0f, 0.0f);
                    gl.glVertex3fv(v4, 0);
                    gl.glTexCoord2f(1.0f, 1.0f);
                    gl.glVertex3fv(v8, 0);
                    gl.glTexCoord2f(0.0f, 1.0f);
                    gl.glVertex3fv(v5, 0);
                }
            // top side
            if (renderSide[4])
                {
                    gl.glNormal3i(0, 0, 1);
                    gl.glTexCoord2f(0.0f, 0.0f);
                    gl.glVertex3fv(v1, 0);
                    gl.glTexCoord2f(1.0f, 0.0f);
                    gl.glVertex3fv(v2, 0);
                    gl.glTexCoord2f(1.0f, 1.0f);
                    gl.glVertex3fv(v3, 0);
                    gl.glTexCoord2f(0.0f, 1.0f);
                    gl.glVertex3fv(v4, 0);
                }

            gl.glEnd();
            texture.disable();

每个立方体都会调用此代码，每个立方体的初始化都相同，但是某些立方体的纹理处理方式不同且“模糊”，而其余的则不然，

这是一张图片:

这个渲染方法在每个 block 的每一帧都被调用，那么问题是如何永久地出现在单个 block 上的呢？

还有一个附带问题，我的应用程序存在大量内存泄漏，我无法追踪，问题出在这里吗？除了设置相机和光源之外，这是 OpenGL 代码的主要部分!

Answer 1

GL_TEXTURE_MAG_FILTER 是每个纹理对象的状态。绑定(bind)你的纹理对象，然后设置它。
