Steps to Create your Lithophane from GIF via C#

Aspose.3D makes it easy for the developers to create your lithophane from the GIF file with just few lines of code.

  • Create some new parameters and create a Mesh object
  • Perform computational operations on Mesh objects
  • GIF file loads 3d scene through Mesh class
  • Call the Scene.Save method with object

System Requirements

Aspose.3D for .NET is supported on all major operating systems. Just make sure that you have the following prerequisites.

  • Microsoft Windows or a compatible OS with .NET Framework, .NET Core, Mono
  • Development environment like Microsoft Visual Studio
  • Aspose.3D for .NET referenced in your project
 

C# code to Create your Lithophane from GIF


//The original image that needs to be uploaded and the 3d file output after saving
    string file = "template.gif";
    string output =System.IO.Path.GetTempPath() + Guid.NewGuid().ToString() + ".fbx";

//Create some new parameters
    var td= TextureData.FromFile(file);
    const float nozzleSize = 0.9f;//0.2mm
    const float layerHeight = 0.2f;
    var grayscale = ToGrayscale(td);
    const float width = 120.0f;//canvas width is 200.0mm
    float height = width / td.Width * td.Height;
    float thickness = 10.0f;//10mm thickness
    float layers = thickness / layerHeight;
    int widthSegs = (int)Math.Floor(width / nozzleSize);
    int heightSegs = (int)Math.Floor(height / nozzleSize);

//Perform computational operations on Mesh objects
    var mesh = new Mesh();
    for (int y = 0; y < heightSegs; y++)
    {
        float dy = (float)y / heightSegs;
        for (int x = 0; x < widthSegs; x++)
        {
            float dx = (float)x / widthSegs;
            float gray = Sample(grayscale, td.Width, td.Height, dx, dy);
            float v = (1 - gray) * thickness;
            mesh.ControlPoints.Add(new Vector4(dx * width, dy * height, v));
        }
    }


    for (int y = 0; y < heightSegs - 1; y++)
    {
        int row = (y * heightSegs);
        int ptr = row;
        for (int x = 0; x < widthSegs - 1; x++)
        {
            mesh.CreatePolygon(ptr, ptr + widthSegs, ptr + 1);
            mesh.CreatePolygon(ptr + 1, ptr + widthSegs, ptr + widthSegs + 1);
            ptr++;
        }
    }

//Generate 3d scene and save objects
    var scene = new Scene(mesh);
    scene.Save(output, FileFormat.FBX7400ASCII);

//The sample method to call
    static float Sample(float[,] data, int w, int h, float x, float y)
    {
        return data[(int)(x * w), (int)(y * h)];
    }

//ToGrayscale method to call
    static float[,] ToGrayscale(TextureData td)
    {
        var ret = new float[td.Width, td.Height];
        var stride = td.Stride;
        var data = td.Data;
        var bytesPerPixel = td.BytesPerPixel;
        for (int y = 0; y < td.Height; y++)
        {
            int ptr = y * stride;
            for (int x = 0; x < td.Width; x++)
            {
                var v = (data[ptr] * 0.21f + data[ptr + 1] * 0.72f + data[ptr + 2] * 0.07f) / 255.0f;
                ret[x, y] = v;
                ptr += bytesPerPixel;
            }
        }
        return ret;
    }
