<h2>Description</h2>

<div class="section">
<p>This sample edits the parameters of procedural textures</p>
</div>

<h2>Required Environment</h2>

<div class="section">
<p>None.</p>

<h2>How to Use</h2>

<th>Input</th>
<th>Operation</th>
        </tr>

        <tr>
<td>+Control Pad Left/Right</td>
<td>Changes the edit position (In) in the lookup table.<BR>Holding down the L or R buttons increases the speed.</td>

<h2>Notes</h2>

<div class="section">
    <ul>
<li>If an SD Card is inserted, the procedural texture will be loaded and saved, and you can capture photos of the screen. These operations are performed on the touch panel.</li>
    </ul>
</div>

<h2>Execution Procedure</h2>

<div class="section">
<p>The following screens are displayed when you run the demo. Adjust the stereoscopic image with the 3D slider.</p>

    <p><img src="Fig/ProcTexEditor.PNG"></p>

<p>Images can be moved using the Circle Pad in combination with the L and R Buttons.<br/>Each procedural texture setting can be changed using the touch panel.</p>
    <ul>
<li>LUT size: Lookup table width selection (2, 4, 8, 16, 32, 64, or 128）</li>
<li>S (Min side): Polygon left edge texture coordinate (to 0.0)</li>
<li>S (Max side): Polygon right edge texture coordinate (0.0 and up)</li>
<li>T (Min side): Polygon bottom edge texture coordinate (to 0.0)</li>
<li>T (Max side): Polygon top edge texture coordinate (0.0 and up)</li>
    </ul>
    <ul>
<li>Save: Saves parameters</li>
<li>Load: Loads parameters saved using the Save button</li>
<li>Capture: Saves captured images to SD Card</li>
    </ul>
    <ul>
<li>Fc: Change the lookup table being edited to F function (color)</li>
<li>Fa: Changes the lookup table being edited to F function (alpha) (only in alpha separate mode)</li>
<li>R: Changes the lookup table being edited to Red Component Table</li>
<li>G: Changes the lookup table being edited to Green Component Table</li>
<li>B: Changes the lookup table being edited to Blue Component Table</li>
<li>A: Changes the lookup table being edited to Alpha Component Table</li>
<li>Nz: Changes the lookup table being edited to Noise Function</li>
    </ul>
    <ul>
<li>Preset: Selects the preset function (name displayed on the right) using the &lt; and &gt; controls below, and overwrites the lookup table with Copy</li>
<li>Unified/Separate: Switches between unified mode and alpha separate mode</li>
<li>Gc(x): Selects the G function (color)</li>
<li>Ga(x): Selects the G function (alpha) (alpha separate mode)</li>
    </ul>
    <ul>
<li>Color: Switches whether to apply lookup tables to each component (R, G, B, and A)</li>
<li>BG: Changes the background color of the upper screen (from 0.0 to 1.0 in steps of 0.1)</li>
    </ul>
    <ul>
<li>Noise: Changes the set of noise parameters (same operation for both U and V components)</li>
<li>ON/OFF: Enables and disables noise</li>
<li>F, P, A: Enables and disables the noise parameters (F, P, and A) (Parameters are adjusted using the + and - controls)</li>
<li>Stop/0.XXX: Sets the value to be added each frame when the noise parameter P varies each frame (no change when stop is used)</li>
<li>Clamp: Switches the texture clamp mode</li>
<li>Shift: Switches the texture shift mode</li>
    </ul>
