75<h2>Description</h2>
76    <div class="section">
77<p>Sets an F function lookup table for alpha mapping of procedural textures. The floating point value you specify is converted into fixed point data by this function and then sent to the GPU. This function is an immediate function. (The immediate function directly generates commands and inserts them into the command buffer.)</p><p>This function first uses <a href="../../../../nn/gd/CTR/ProceduralTextureStage/Helper/ConvertLookUpTableDataFloatToNative.html"><CODE>ProceduralTextureStage::Helper::ConvertLookUpTableDataFloatToNative</CODE></a> to convert from a float to the specified integer value.</p><!-- write here --></div>
