Precise vertex positions

Questions & Answers

Hello,

I was wondering how to get precise vertex positions in a mesh (with as many decimal places as needed as

 function Start (){
     var thisMatrix = transform.localToWorldMatrix;
     var vertices = GetComponent.<MeshFilter>().mesh.vertices;
     for (vertex in vertices) {
         print("mesh1 vertex at " + thisMatrix.MultiplyPoint3x4(vertex) );
     }
 }

seems to return rounded positions (up to 1 decimal place)

Vertex positions are floating point values - they don’t have any number of fixed decimal places. The print method in your example, however, does truncate values shown in the console because the ToString() method only shows a few decimal places of each component of a vector3.

You’ll probably yield more accurate output in the console window by outputting each float value separately:

print("mesh1 vertex at " + thisMatrix.MultiplyPoint3x4(vertex).x + "," + thisMatrix.MultiplyPoint3x4(vertex).y + "," + thisMatrix.MultiplyPoint3x4(vertex).z );
