How to pass a points arry to a Dotnet function

[flyingc007]

Hi,

I have an array of points,such as #([1,3,4],[53,12,1])

If I want to pass it as an argument to a DotNet funtion .

How would I do?

Thanks in advance.

(where do I edit the post?I can't find )

This question  is about MAXScript.

I need to pass an argument of  points array to a DotNet function.

[istan]

Visual Studio / Solution / References / Add Reference: "3dsmax_path\Autodesk.Max.DLL"

Then use the object browser. There you'll find everything Max is exposing to dotNet.

There's another interesting one: MaxCustomControls.DLL

it depends on the type of dotnet function you are using ... show your function definition to see the type of input data

For example.

I have a point3 struct,and a sum function like this

public struct point3
    {
        public float x, y, z;
        public point3(float x1, float y1, float z1)
        {
            x = x1;
            y = y1;
            z = z1;
        }
    }
public static point3 sum(int num,point3[] pts)
        {
            
            for (int i = 1; i < num; i++)
            {
                pts[1].x += pts[i].x;
                pts[1].y += pts[i].y;
                pts[1].z += pts[i].z;

            }
            return pts[1];
        }

I want to call the function in MaxScript,so the problem is how to pass a points array to the sum() function.

[flyingc007]

sorry ,I forgot to mention one thing.

I need to call the function in 3dsmax 2012 or below the version.

But "Autodesk.3dsmax.dll" is not availibale in these version.

[istan]

arr=#( dotnetobject("mydotnetclass.point3") 1 2 3, dotnetobject("mydotnetclass.point3") 4 5 6)
local ret = dotnetclass("mydotnetclass").sum arr.count arr

I'd do it somehow like this under Max2020..

Yes,it can work,but it seems a bit complex

 it will be much better if the array can be turn to pointer to a memory.

pass it as a pointer to float's array... and cast in c# .. three floats per point
