◆  ~PolygonReduction()

成员函数文档编制

◆  Alloc()

Allocates a PolygonReduction . Destroy the allocated PolygonReduction with Free() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

返回

The allocated PolygonReduction ，或 nullptr if the allocation failed.

◆  Free()

Destructs PolygonReductions allocated with Alloc() 。使用 AutoAlloc to automate the allocation and destruction based on scope.

参数

[in]

node

The PolygonReduction to destruct. If the pointer is nullptr nothing happens. The pointer is assigned nullptr afterwards.

◆  PreProcess()

Starts the background or synchronous preprocessing that sets up the polygon reduction cache.

参数

[in]

data

The data for the reduction.

返回

true if successful, otherwise false .

◆  IsPreprocessing()

Checks whether the background preprocessing thread is still running.

返回

true if preprocessing is ongoing, otherwise false .

◆  StopPreprocessing()

Aborts preprocessing if it is running in the background. Resets the interactive settings values.

◆  Reset()

Aborts preprocessing if it is running in the background and frees all temporary data.

◆  SetReductionStrengthLevel()

Sets the reduction strength level if the desired level is different than the current one.

参数

[in]

strengthLevel

The desired reduction strength level.

返回

true if successful, otherwise false .

◆  SetTriangleLevel()

Reduces or restores the mesh to the desired number of triangles.

注意

If the desired level is different than the current level, at least one edge collapse or restore will be performed. The actual resulting number of triangles may be slightly different.

参数

[in]

desiredLevel

The desired number of triangles on call.

返回

true if successful, otherwise false .

◆  SetVertexLevel()

Reduces or restores the mesh to the desired number of vertices.

注意

If the desired level is different than the current level, at least one edge collapse or restore will be performed. The actual resulting number of vertices may be slightly different.

参数

[in]

desiredLevel

The desired number of vertices on call.

返回

true if successful, otherwise false .

◆  SetRemainingEdgesLevel()

Reduces or restores the mesh to the desired number of edges remaining to collapse.

注意

If the desired level is different than the current level, at least one edge collapse or restore will be performed. The actual resulting number of edges may be slightly different.

参数

[in]

desiredLevel

The desired collapse stack index.

返回

true if successful, otherwise false .

◆  GetReductionStrengthLevel()

Queries the current reduction strength level.

返回

The reduction strength percentage: 0 means no reduction performed, 1 means maximum reduction performed.

◆  GetTriangleLevel()

Queries the current triangle count.

返回

The triangle count.

◆  GetVertexLevel()

Queries the current vertex count.

返回

The vertex count.

◆  GetRemainingEdgesLevel()

Queries the current remaining number of edges available to collapse.

返回

The remaining edges level.

◆  GetMaxReductionStrengthLevel()

Queries the maximum reduction strength percentage.

返回

The maximum reduction strength percentage. Always 1.0 .

◆  GetMaxTriangleLevel()

Queries the triangle count when no reduction has been performed.

返回

The maximum triangle count.

◆  GetMaxVertexLevel()

Queries the vertex count when no reduction has been performed.

返回

The maximum vertex count.

◆  GetMaxRemainingEdgesLevel()

Queries the total number of possible edge collapses.

返回

The maximum collapse count.

◆  GetMinTriangleLevel()

Queries the triangle count when complete reduction has been performed.

返回

The minimum triangle count. May be non-zero if border constraints are enabled.

◆  GetMinVertexLevel()

Queries the vertex count when complete reduction has been performed.

返回

The minimum vertex count. May be non-zero if border constraints are enabled.

◆  GetData()

Retrieves the associated PolygonReductionData .

返回

The polygon reduction data.

◆  IsValid()

Checks if a valid object and a valid document are associated with the PolygonReduction instance.

返回

true 若 PolygonReduction instance is valid, otherwise false .
