viz.POINTS

Creates a point for each vertex in the list.

viz.LINES

Creates a series of separate lines by splitting the list of vertices into pairs and drawing a line between each member in each pair.

viz.LINE_STRIP

Creates a series of connected lines by drawing a line between each vertex and the next vertex in the list.

viz.LINE_LOOP

Creates a loop of lines by drawing a line between each vertex and the next vertex on the list, and then connecting the last vertex with the first vertex on the list.

viz.TRIANGLES

Creates a series of separate triangular surfaces. The list of vertices is split into sets of three which each define a separate triangle.

viz.TRIANGLE_STRIP

Creates an series of triangular surfaces connected along shared edges.  Each contiguous trio of vertices defines a triangle in the strip.

viz.TRIANGLE_FAN

Creates a fan of triangular surfaces. The first vertex is linked to each subsequent pair of vertices tp define each triangle in the fan.

viz.QUADS

Creates a series of separate quadrilateral surfaces. The list of vertices is split into sets of four which each define a separate quadrilateral.

viz.QUAD_STRIP

Creates a series of quadrilateral surfaces connected along shared edges. Each contiguous series of four vertices defines a quadrilateral in the strip.  

viz.POLYGON

Creates a polygon. Each vertex provides a point for the polygon. Each of the inside angles created by linking the vertices must be acute.
