Expand description

Primitive type the input mesh is composed of.

Corresponds to WebGPU GPUPrimitiveTopology.

Variants

PointList

Vertex data is a list of points. Each vertex is a new point.

LineList

Vertex data is a list of lines. Each pair of vertices composes a new line.

Vertices 0 1 2 3 create two lines 0 1 and 2 3

LineStrip

Vertex data is a strip of lines. Each set of two adjacent vertices form a line.

Vertices 0 1 2 3 create three lines 0 1, 1 2, and 2 3.

TriangleList

Vertex data is a list of triangles. Each set of 3 vertices composes a new triangle.

Vertices 0 1 2 3 4 5 create two triangles 0 1 2 and 3 4 5

TriangleStrip

Vertex data is a triangle strip. Each set of three adjacent vertices form a triangle.

Vertices 0 1 2 3 4 5 creates four triangles 0 1 2, 2 1 3, 2 3 4, and 4 3 5
