Detailed Description

Interface class that returns the triangle mesh specific result of a query operation.

The interface class sub classes from IScene_lookup_result to provide additional results related to an entry of a ITriangle_mesh_scene_element elements. Each entry or lookup index refers to a single triangle of the triangle mesh and the per-vertex attributes stored along with the triangle, such as the per-vertex colors. The lookup result provides the per-vertex values in counter-clockwise order.

[out]	n2	Returns the third per-vertex normal.

get_texture_coordinates()

virtual void nv::index::ITriangle_mesh_lookup_result::get_texture_coordinates ( mi::math::Vector_struct< mi::Float32, 2 > &  st0, mi::math::Vector_struct< mi::Float32, 2 > &  st1, mi::math::Vector_struct< mi::Float32, 2 > &  st2  ) const

pure virtual

A texture coordinate can be defined for each vertex of the triangle of a triangle.

The call provides the per-vertex texture coordinate.

Parameters

[out]	st0	Returns the first per-vertex texture coordinate.
[out]	st1	Returns the second per-vertex texture coordinate.
[out]	st2	Returns the third per-vertex texture coordinate.

get_vertices()

virtual void nv::index::ITriangle_mesh_lookup_result::get_vertices ( mi::math::Vector_struct< mi::Float32, 3 > &  v0, mi::math::Vector_struct< mi::Float32, 3 > &  v1, mi::math::Vector_struct< mi::Float32, 3 > &  v2  ) const

pure virtual

Each triangle of a triangle mesh is defined by 3 vertices with their locations defined in the triangle mesh's 3D space.

The vertices are defined in counter-clockwise order.
