Member Function Documentation

CreatePolyTriangulation()

Handle< Poly_Triangulation > Prs3d_ToolQuadric::CreatePolyTriangulation

(

const gp_Trsf &

theTrsf

)

const

Generate primitives for 3D quadric surface presentation.

Parameters

theTrsf

[in] optional transformation to apply

Returns

generated triangulation

CreateTriangulation()

Handle< Graphic3d_ArrayOfTriangles > Prs3d_ToolQuadric::CreateTriangulation

(

const gp_Trsf &

theTrsf

)

const

Generate primitives for 3D quadric surface presentation.

Parameters

theTrsf

[in] optional transformation to apply
