D3D10_PRIMITIVE_TOPOLOGY enumeration

Applies to: desktop apps | Metro style apps

How the pipeline interprets vertex data that is bound to the input-assembler stage. These primitive types determine how the vertex data is rendered on screen.

Syntax

Copy

typedef enum D3D10_PRIMITIVE_TOPOLOGY {
  D3D10_PRIMITIVE_TOPOLOGY_UNDEFINED           = 0,
  D3D10_PRIMITIVE_TOPOLOGY_POINTLIST           = 1,
  D3D10_PRIMITIVE_TOPOLOGY_LINELIST            = 2,
  D3D10_PRIMITIVE_TOPOLOGY_LINESTRIP           = 3,
  D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST        = 4,
  D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP       = 5,
  D3D10_PRIMITIVE_TOPOLOGY_LINELIST_ADJ        = 10,
  D3D10_PRIMITIVE_TOPOLOGY_LINESTRIP_ADJ       = 11,
  D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST_ADJ    = 12,
  D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP_ADJ   = 13 
} D3D10_PRIMITIVE_TOPOLOGY;

Constants

D3D10_PRIMITIVE_TOPOLOGY_UNDEFINED: The IA stage has not been initialized with a primitive topology. The IA stage will not function properly unless a primitive topology is defined.
D3D10_PRIMITIVE_TOPOLOGY_POINTLIST: Interpret the vertex data as a list of points.
D3D10_PRIMITIVE_TOPOLOGY_LINELIST: Interpret the vertex data as a list of lines.
D3D10_PRIMITIVE_TOPOLOGY_LINESTRIP: Interpret the vertex data as a line strip.
D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST: Interpret the vertex data as a list of triangles.
D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP: Interpret the vertex data as a triangle strip.
D3D10_PRIMITIVE_TOPOLOGY_LINELIST_ADJ: Interpret the vertex data as list of lines with adjacency data.
D3D10_PRIMITIVE_TOPOLOGY_LINESTRIP_ADJ: Interpret the vertex data as line strip with adjacency data.
D3D10_PRIMITIVE_TOPOLOGY_TRIANGLELIST_ADJ: Interpret the vertex data as list of triangles with adjacency data.
D3D10_PRIMITIVE_TOPOLOGY_TRIANGLESTRIP_ADJ: Interpret the vertex data as triangle strip with adjacency data.

Remarks

The D3D10_PRIMITIVE_TOPOLOGY enumeration is type defined in the D3D10.h header file as a D3D_PRIMITIVE_TOPOLOGY enumeration, which is fully defined in the D3DCommon.h header file.
