[Threejs读取原始图像数据时出现2D纹理阵列问题

Question

[当我尝试执行此example时，我看到它在当前sample的情况下工作正常，但是当我尝试放置包含连续2D帧的二进制文件时，从here导出了jpg图像，但没有得到。像这样的详细图像：

这是转换器二进制代码：

<?php
header("Content-type: application/octet-stream");
header('Content-disposition: attachment; filename=head256x256x1092.bin');

$dirs = scandir('512');
unset($dirs[0]);
unset($dirs[1]);
natsort($dirs);
foreach($dirs as $dir):
$fp = fopen('512/'.$dir, "r");
while (!feof($fp))
{
    echo fread($fp, 65536);
    flush(); // this is essential for large downloads
}
fclose($fp);

endforeach;
?>
~       

这是Threejs文件阅读器：

new THREE.FileLoader()
      .setResponseType( 'arraybuffer' )
      .load( 'head256x256x1092.zip', function ( data ) {

        var zip = new JSZip( data );
        var array = zip.files[ 'head256x256x1092.bin' ].asUint8Array();

        var texture = new THREE.DataTexture2DArray( array, 256, 256, 109 );
        texture.format = THREE.RedFormat;
        texture.type = THREE.UnsignedByteType;
        texture.needsUpdate = true;
        var material = new THREE.ShaderMaterial( {
          uniforms: {
            diffuse: { value: texture },
            depth: { value: 0 },
            size: { value: new THREE.Vector2( planeWidth, planeHeight ) }
          },
          vertexShader: document.getElementById( 'vs' ).textContent.trim(),
          fragmentShader: document.getElementById( 'fs' ).textContent.trim()
        } );
        var geometry = new THREE.PlaneBufferGeometry( planeWidth, planeHeight );
        mesh = new THREE.Mesh( geometry, material );
        scene.add( mesh );
      } );

DataTexture是rgb的数组jpeg文件是压缩数据，不一样。您可以使用此功能：
