Nzy3d.Winforms 0.1.0

Nzy3d

• Updated net6.0 version of nzy3d-api
• Uses OpenTK 4.6.7 and the more recent WinForms GLControl
• Perspective mode bug fixed
• Available in Winforms and native WPF (WFP available in the wpf branch due to version issue with the OpenTK control, see issue 61)

How to

Samples

See Nzy3d.WinformsDemo and the ChartsHelper for Winforms examples

Mapper surface

// Create the chart
Chart.Chart chart = new Chart.Chart(renderer3D, Quality.Nicest);
chart.View.Maximized = false;
chart.View.CameraMode = CameraMode.PERSPECTIVE;
chart.View.IncludingTextLabels = true;

// Create a range for the graph generation
var range = new Maths.Range(-150, 150);
const int steps = 50;

// Build a nice surface to display with cool alpha colors 
// (alpha 0.8 for surface color and 0.5 for wireframe)
var surface = Plot3D.Builder.Builder.BuildOrthonomal(new OrthonormalGrid(range, steps, range, steps), new MyMapper());
surface.ColorMapper = new ColorMapper(new ColorMapRainbow(), surface.Bounds.ZMin, surface.Bounds.ZMax, new Color(1, 1, 1, 0.8));
surface.FaceDisplayed = true;
surface.WireframeDisplayed = true;
surface.WireframeColor = Color.CYAN;
surface.WireframeColor.Mul(new Color(1, 1, 1, 0.5));

// Add surface to chart
chart.Scene.Graph.Add(surface);

Delaunay surface

// Create data
const int size = 100;
List<Coord3d> coords = new List<Coord3d>(size);
float x, y, z;
var r = new Random(0);

for (int i = 0; i < size; i++)
{
	x = r.NextSingle() - 0.5f;
	y = r.NextSingle() - 0.5f;
	z = r.NextSingle() - 0.5f;
	coords.Add(new Coord3d(x, y, z));
}

// Create chart
Chart.Chart chart = new Chart.Chart(renderer3D, Quality.Nicest);
chart.View.Maximized = false;
chart.View.CameraMode = CameraMode.PERSPECTIVE;
chart.View.IncludingTextLabels = true;

// Create surface
var surface = Plot3D.Builder.Builder.BuildDelaunay(coords);
surface.ColorMapper = new ColorMapper(new ColorMapRainbow(), surface.Bounds.ZMin, surface.Bounds.ZMax, new Color(1, 1, 1, 0.8));
surface.FaceDisplayed = true;
surface.WireframeDisplayed = true;
surface.WireframeColor = Color.CYAN;
surface.WireframeColor.Mul(new Color(1, 1, 1, 0.5));

// Add surface to chart
chart.Scene.Graph.Add(surface);

Scatter graph

// Create data
var points = new Coord3d[size];
var colors = new Color[size];

float x, y, z;
const float a = 0.25f;

var r = new Random(0);
for (int i = 0; i < size; i++)
{
	x = r.NextSingle() - 0.5f;
	y = r.NextSingle() - 0.5f;
	z = r.NextSingle() - 0.5f;
	points[i] = new Coord3d(x, y, z);
	colors[i] = new Color(x, y, z, a);
}

// Create chart
Chart.Chart chart = new Chart.Chart(renderer3D, Quality.Nicest);
chart.View.Maximized = false;
chart.View.CameraMode = CameraMode.PERSPECTIVE;
chart.View.IncludingTextLabels = true;

// Create scatter
var scatter = new Scatter(points, colors);

// Add surface to chart
chart.Scene.Graph.Add(scatter);
