Expand description
Describes the type of geometric primitives, created from vertex data.
Variants
PointList
Each vertex represents a single point.
LineList
Each pair of vertices represent a single line segment. For example, with [a, b, c, d, e]
, a
and b
form a line, c
and d
form a line, and e
is discarded.
LineStrip
Every two consecutive vertices represent a single line segment. Visually forms a “path” of
lines, as they are all connected. For example, with [a, b, c]
, a
and b
form a line
line, and b
and c
form a line.
TriangleList
Each triplet of vertices represent a single triangle. For example, with [a, b, c, d, e]
,
a
, b
, and c
form a triangle, d
and e
are discarded.
TriangleStrip
Every three consecutive vertices represent a single triangle. For example, with [a, b, c, d]
, a
, b
, and c
form a triangle, and b
, c
, and d
form a triangle.
PatchList(PatchSize)
Patch list, used with shaders capable of producing primitives on their own (tessellation)
