Script Preparation code:
var objectItem = { a:1, b:2, c:3, } var arrayItem = new Float32Array([1,2,3]); var output = new Float32Array(300);
Tests:
copy from object
var index = 0; for(var i = 0; i < 300/3; i++) { output[index++] = objectItem.a; output[index++] = objectItem.b; output[index++] = objectItem.c; }
copy from floatArray
var index = 0; for(var i = 0; i < 300/3; i++) { output[index++] = arrayItem[0]; output[index++] = arrayItem[1]; output[index++] = arrayItem[2]; }
