D3D12_PRIMITIVE_TOPOLOGY_TYPE Enumeration

Specifies how the pipeline interprets geometry or hull shader input primitives.

Syntax

typedef enum D3D12_PRIMITIVE_TOPOLOGY_TYPE
{
    D3D12_PRIMITIVE_TOPOLOGY_TYPE_UNDEFINED = 0,
    D3D12_PRIMITIVE_TOPOLOGY_TYPE_POINT = 1,
    D3D12_PRIMITIVE_TOPOLOGY_TYPE_LINE = 2,
    D3D12_PRIMITIVE_TOPOLOGY_TYPE_TRIANGLE = 3,
    D3D12_PRIMITIVE_TOPOLOGY_TYPE_PATCH = 4,
    D3D12XBOX_PRIMITIVE_TOPOLOGY_TYPE_RECT = 19,
    D3D12XBOX_PRIMITIVE_TOPOLOGY_TYPE_QUAD = 32
} D3D12_PRIMITIVE_TOPOLOGY_TYPE;

Constants

Constant	Description
D3D12_PRIMITIVE_TOPOLOGY_TYPE_UNDEFINED	The shader has not been initialized with an input primitive type.
D3D12_PRIMITIVE_TOPOLOGY_TYPE_POINT	Interpret the input primitive as a point.
D3D12_PRIMITIVE_TOPOLOGY_TYPE_LINE	Interpret the input primitive as a line.
D3D12_PRIMITIVE_TOPOLOGY_TYPE_TRIANGLE	Interpret the input primitive as a triangle.
D3D12_PRIMITIVE_TOPOLOGY_TYPE_PATCH	Interpret the input primitive as a control point patch.
D3D12XBOX_PRIMITIVE_TOPOLOGY_TYPE_RECT	Interpret the input primitive as a rectangle. An Xbox extension. Serves as the base topology for the D3D_PRIMITIVE_TOPOLOGY_RECTLIST enumeration constant.
D3D12XBOX_PRIMITIVE_TOPOLOGY_TYPE_QUAD	Interpret the input primitive as a quadrangle. An Xbox extension. Serves as the base topology for the D3D_PRIMITIVE_TOPOLOGY_QUADLIST enumeration constant.

Remarks

This enumeration is used by the D3D12_GRAPHICS_PIPELINE_STATE_DESC structure.
