<p><strong>向量元素的获取（成分选择）</strong></p>
<p>向量中单独的成分可以通过 <strong>{x,y,z,w}, {r,g,b,a}</strong> 或者 <strong>{s,t,p,q}</strong> 的记法来表示。这些不同的记法用于 <strong>顶点</strong> ， <strong>颜色</strong> ， <strong>纹理坐标</strong> 。在成分选择中，不可以混合使用这些记法。其中 <strong>{s,t,p,q}</strong> 中的 <strong>p</strong> 替换了<strong>纹理</strong>的 <strong>r</strong> 坐标，因为与颜色 <strong>r</strong> 重复了。下面是用法举例：</p>

<h2 id="运算">运算</h2>
<p><strong>注意 GLSL 中没有隐式转换，即便在多维向量中也没有</strong></p>
<pre><code>**逐分量运算**
**vec，mat** 这些类型其实是由 **float** 复合而成的，当它们与**float** 运算时，其实就是在每一个分量上分别与 **float** 进行运算，这就是所谓的 **逐分量运算** 。**GLSL** 里，大部分涉及 **vec，mat** 的运算都是逐分量运算，但也并不全是。下文中就会讲到特例。
**逐分量运算** 是线性的，这就是说 vec 与 float 的运算结果是还是 **vec** 。</code></pre>
<h4 id="不同类型-float-与-int-间的运算">1、不同类型 float 与 int 间的运算:</h4>
<p><strong>float</strong> 与 <strong>int</strong> 之间进行运算，需要进行一次显示转换</p>
<h4 id="float-与-vec向量mat矩阵-的运算">2、float 与 vec(向量)、mat(矩阵) 的运算:</h4>
<p><strong>int</strong> 与 <strong>vec，mat</strong> 之间是不可运算的，因为 <strong>vec</strong> 和 <strong>mat</strong> 中的每一个分量都是 <strong>float</strong> 类型的，无法与 <strong>int</strong> 进行逐分量计算。</p>
<h4 id="vec向量-与-vec向量运算">3、vec(向量) 与 vec(向量)运算：</h4>
<p>两向量间的运算首先要保证操作数的阶数都相同，否则不能计算。</p>
<h4 id="vec向量-与-mat矩阵">4、vec(向量) 与 mat(矩阵):</h4>
<p>要保证操作数的阶数相同，且 <strong>vec</strong> 与 <strong>mat</strong> 间只存在乘法运算。 它们的计算方式和线性代数中的矩阵乘法相同， <strong>不是逐分量运算</strong> 。</p>
<h4 id="mat矩阵-与-mat矩阵">5、mat(矩阵) 与 mat(矩阵):</h4>
<p>⚠️要保证操作数的阶数相同。</p>
<p>在 <strong>mat</strong> 与 <strong>mat</strong> 的运算中，除了乘法是线性代数中的矩阵乘法外，其余的运算仍为 <strong>逐分量运算</strong> 。简单说就是只有乘法是特殊的，其余都和 <strong>vec</strong> 与 <strong>vec</strong> 运算类似。</p>
<h2 id="精度限定">精度限定</h2>
<p><strong>GLSL</strong> 在进行光栅化着色的时候，会产生大量的浮点数运算，这些运算可能是当前设备所不能承受的，所以 <strong>GLSL</strong> 提供了 <strong>3</strong> 种浮点数精度，我们可以根据不同的设备来使用合适的精度。</p>
<p>在变量前面加上 <strong><code>highp</code>、<code>mediump</code>、<code>lowp</code></strong> 即可完成对该变量的精度声明：</p>
<figure class="highlight c"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">lowp <span class="keyword">float</span> color;</span><br><span class="line">varying mediump vec2 Coord;</span><br><span class="line"><span class="function">lowp ivec2 <span class="title">foo</span><span class="params">(lowp mat3)</span></span>;</span><br><span class="line">highp mat4 m;</span><br></pre></td></tr></table></figure>
<p>我们一般在 <strong>片元着色器（fragment shader)</strong> 最开始的地方加上 <code>precision mediump float;</code> 便设定了默认的精度，这样所有没有显式表明精度的变量都会按照设定好的默认精度来处理。</p>
<p>⚠️注意 <strong>GLSL</strong> 函数中没有递归！</p>

<p>一个EUI循环列表项需要：</p>
<p>在数据层添加字典<br>
在创建/显示/刷新时添加字典、监听，并显示<br>
在隐藏/销毁时清空字典<br>
需要一个列表项响应函数</p>
<p>只要满足上述条件，则不一定在ShowWindow和HideWindow中书写相关代码</p>
