Description

Mesh topology types used by MeshBuilder.

Enum Value	Description
MeshTopology.Lines	Draws unconnected line segments. Each group of two vertices specifies a new line segment.
MeshTopology.LineStrip	Draws connected line segments. Starting with the second vertex, a line is drawn between each vertex and the preceding one.
MeshTopology.Points	Draws individual points. Each vertex specifies a new point to draw.
MeshTopology.Triangles	Draws unconnected triangles. Each group of three vertices specifies a new triangle.
MeshTopology.TriangleFan	Draws connected triangles sharing one central vertex. The first vertex is the shared one, or “hub” vertex. Starting with the third vertex, each vertex forms a triangle connecting with the previous vertex and hub vertex.
MeshTopology.TriangleStrip	Draws connected triangles in a strip. After the first two vertices, each vertex defines the third point on a new triangle extending from the previous one.

Examples

// Constructs a new mesh builder
var builder = new MeshBuilder([
    { name: "position", components: 3 },
    { name: "normal", components: 3, normalized: true },
    { name: "texture0", components: 2 },
    { name: "color", components: 4 },
]);

builder.topology = MeshTopology.Triangles;
builder.indexType = MeshIndexType.UInt16;
