1) Zoom persistence mode now fixes object in pixel coordinates and is independent on view size 2) Used gp_GTrsf instead of gp_Trsf SelectMgr_ViewerSelector to store Graphic3d_Mat4d 3) Zoom persisted objects changed behavior (become bigger) therefore test cases were updated according to new state. 4) Corrected scale for rectangular frustum Updated test for manipulator

//! This class is used to handle polyline selection. The main principle of polyline selection
|
|
//! algorithm is to split the polygon defined by polyline onto triangles. Than each of
|

//! them is considered as a base for triangular frustum building. In other
|
|
//! words, each triangle vertiex will be projected from 2d screen space to 3d world space
|
|
//! onto near and far view frustum planes. Thus, the projected triangles make up the bases of
|
|
//! selecting frustum. When the set of such frustums is created, the function determining
|
|
//! selection iterates through triangular frustum set and searches for overlap with any
|
|
//! frustum.
