Member Function Documentation

Create()

static Subdivider * Assimp::Subdivider::Create ( Algorithm  algo )

static

Create a subdivider of a specific type.

Parameters

algo	Algorithm to be used for subdivision

Returns

Subdivider instance.

Subdivide() [1/2]

virtual void Assimp::Subdivider::Subdivide ( aiMesh **  smesh, size_t  nmesh, aiMesh **  out, unsigned int  num, bool  discard_input = false  )

pure virtual

Subdivide multiple meshes using the selected algorithm.

This avoids erroneous smoothing on objects consisting of multiple per-material meshes. Usually, most 3d modellers smooth on a per-object base, regardless the materials assigned to the meshes.

Parameters

smesh	Array of meshes to be subdivided. Must be in verbose format.
nmesh	Number of meshes in smesh.
out	Receives the output meshes. The array must be sufficiently large (at least nmesh elements) and may not overlap the input array. Output meshes map one-to-one to their corresponding input meshes. The meshes are allocated by the function.
discard_input	If true is passed, input meshes are deleted after the subdivision is complete. This can improve performance because it allows the optimization of reusing existing meshes for intermediate results.
num	Number of subdivisions to perform.

Precondition

nmesh != 0, smesh and out may not overlap

Subdivide() [2/2]

virtual void Assimp::Subdivider::Subdivide ( aiMesh *  mesh, aiMesh *&  out, unsigned int  num, bool  discard_input = false  )

pure virtual

Subdivide a mesh using the selected algorithm.

Parameters

mesh	First mesh to be subdivided. Must be in verbose format.
out	Receives the output mesh, allocated by me.
num	Number of subdivisions to perform.
discard_input	If true is passed, the input mesh is deleted after the subdivision is complete. This can improve performance because it allows the optimization to reuse the existing mesh for intermediate results.

Precondition

out!=mesh
