Primitve topology.

Specifies how the input assembler (fixed-function) of the graphics pipeline will assemble primitives based on the incoming vertex data.

Variants

Points

Independent vertex points.

One vertex corresponds to one point. The size of a point can be changed dynamically in the vertex, geometry or tessellation evaluation stage. A point is rendered as square.

GLSL: gl_PointSize.

Lines

Lines segment list.

Every two consecutive vertices will form a line segment.

LineStrip

Lines segment strip.

The vertices will build a connected list of line segments.

Triangles

Triangle list.

Three consecutive vertices will form triangle.
