Question

我有一个＆＃34;隐藏＆＃34;文件并将其转换为stl，我想手动重新设计以创建可以使用任何文件执行此操作的软件

STL BASE

facet normal -7.028554081916809e-1 -6.662387847900391e-1 2.4923914670944214e-1
  outer loop

  endloop
endfacet

加密文件将成功：

纹理（PNG）
顶点（STL）
Facets（BINARY application / octet-stream）
FacetMarks（STL）
两个Matrix4x4（ARRAY）
每个顶点纹理坐标（BINARY application / octet-stream）

顶点：

两个Matrix4x4

//Focus2FinalTrans
var identityMatrix0 = [
  [-0.139106587, -0.9896074,    0.0364231542, 22.71722],
  [ 0.9774915,   -0.143108979, -0.155016765,  -3.1819346],
  [ 0.1586182,    0.01403947,   0.9872402,   -16.35489],
  [ 0            ,0          ,  0        ,     1]
];

//AlignToBiteTransformation
var identityMatrix = [
  [-0.9909725,   8.663357E-8,     0.134065166,   7.589744],
  [-8.742278E-8, -1,             -7.203359E-17, -1.193707],
  [0.134065166,  -1.17203491E-8,  0.9909725,    -1.02678967],
  [0,             0,              0,             1]
];

我无法理解如何获取所有获得加密文件的结果以获得与 STL BASE

我尝试过：

function multiplyMatrixAndPoint(matrix, point) {
    var c0r0 = matrix[ 0], c1r0 = matrix[ 1], c2r0 = matrix[ 2], c3r0 = matrix[ 3];
    var c0r1 = matrix[ 4], c1r1 = matrix[ 5], c2r1 = matrix[ 6], c3r1 = matrix[ 7];
    var c0r2 = matrix[ 8], c1r2 = matrix[ 9], c2r2 = matrix[10], c3r2 = matrix[11];
    var c0r3 = matrix[12], c1r3 = matrix[13], c2r3 = matrix[14], c3r3 = matrix[15];
    var x = point[0];
    var y = point[1];
    var z = point[2];
    var w = point[3];
    var resultX = (x * c0r0) + (y * c0r1) + (z * c0r2) + (w * c0r3);
    var resultY = (x * c1r0) + (y * c1r1) + (z * c1r2) + (w * c1r3);
    var resultZ = (x * c2r0) + (y * c2r1) + (z * c2r2) + (w * c2r3);
    var resultW = (x * c3r0) + (y * c3r1) + (z * c3r2) + (w * c3r3);
    return [resultX, resultY, resultZ, resultW]
}

和...

var transform = function(point,vector){
  var p = [0,0,0];
  for (var i = 0; i < 3; i++) {
    p[i] += vector[i][3];
    for (var c = 0; c < 3; c++) {
       p[i] += point[c] * vector[i][c];
     }; 
  };
  return p;
}

与Vertex联合方面一样？
