I'm trying to applya texture on each faces of my box, here's the code:
int boxWidth = 40;
Point3D location = new Point3D(0, 0, 0);
var meshBuilder = new MeshBuilder();
meshBuilder.AddBox(new Point3D(location.X, location.Y, location.Z), boxWidth, boxWidth, boxWidth);
PointCollection pntCol = new PointCollection();
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
pntCol.Add(new Point(boxWidth, boxWidth));
pntCol.Add(new Point(0, boxWidth));
pntCol.Add(new Point(0, 0));
pntCol.Add(new Point(boxWidth, 0));
meshBuilder.TextureCoordinates = pntCol;
ImageBrush brush = new ImageBrush();
brush.ImageSource = new BitmapImage(new Uri(@"mv-pallet-cubi.jpg", UriKind.Relative));
brush.TileMode = TileMode.Tile;
brush.ViewportUnits = BrushMappingMode.RelativeToBoundingBox;
brush.ViewboxUnits = BrushMappingMode.Absolute;
brush.Stretch = Stretch.None;
brush.AlignmentX = AlignmentX.Left;
brush.AlignmentY = AlignmentY.Top;
brush.Viewbox = new Rect(0, 0, brush.ImageSource.Width, brush.ImageSource.Height);
brush.Viewport = new Rect(0, 0, 1, 1);
DiffuseMaterial mat = new DiffuseMaterial(brush);
GeometryModel3D gModel3D = new GeometryModel3D { Geometry = meshBuilder.ToMesh(), Material = mat };
ModelVisual3D mvt = new ModelVisual3D();
mvt.Content = gModel3D;
viewport.Children.Add(mvt);
The width and height of my box are 40 and the size of the texture are 90x90. Basically the effect I got is this:
If I set the dimensions of my box as 90 (same of the texture), the effect is what I want.
Basically I would stretch the whole texture on a box of any dimension. Any helps?
Your texture coordinate need to set to 0 to 1 range instead of 0 to box width
