}

Topology of primitives.

Variants

PointList

Vertices are assembled into points. Each vertex form one point primitive.

Example

Vertirces a, b, c, d will form points a, b, c, d.

LineList

Vertices are assembled into lines. Each separate pair of vertices forms one line primitive.

Example

Vertirces a, b, c, d will form lines a, b and c, d.

LineStrip

Vertices are assembled into lines. Each pair of vertices forms one line primitive.

Example

Vertirces a, b, c, d will form lines a, b, b, c and c, d.

TriangleList

Vertices are assempled into triangles. Each separate triplet of vertices forms one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c and d, e, f.

TriangleStrip

Vertices are assempled into triangles. Each triplet of vertices forms one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c, b, c, d, c, d, e and d, e, f.

TriangleFan

Vertices are assempled into triangles. First vertex is shared with all triangles. Then each pair and shared vertex form one triangle primitive.

Example

Vertirces a, b, c, d, e, f will form triangles a, b, c, a, c, d, a, d, e and a, e, f.
