TGeoXtru Class Reference

An extrusion with fixed outline shape in x-y and a sequence of z extents (segments).

The overall scale of the outline scales linearly between z points and the center can have an x-y offset.

Based on the initial implementation of R. Hatcher

Creation of TGeoXtru shape

A TGeoXtru represents a polygonal extrusion. It is defined by the:

  1. 'Blueprint' of the arbitrary polygon representing any Z section. This is an arbitrary polygon (convex or not) defined by the X/Y positions of its vertices.
  1. A sequence of Z sections ordered on the Z axis. Each section defines the 'actual' parameters of the polygon at a given Z. The sections may be translated with respect to the blueprint and/or scaled. The TGeoXtru segment in between 2 Z sections is a solid represented by the linear extrusion between the 2 polygons. Two consecutive sections may be defined at same Z position.
  1. TGeoXtru *xtru = TGeoXtru(Int_t nz);

    where nz=number of Z planes

  2. Double_t x[nvertices]; // array of X positions of blueprint polygon vertices

    Double_t y[nvertices]; // array of Y positions of blueprint polygon vertices

  3. xtru->DefinePolygon(nvertices,x,y);
  4. DefineSection(0, z0, x0, y0, scale0); // Z position, offset and scale for first section

    ‘DefineSection(1, z1, x1, y1, scale1); // -’'- second section .... DefineSection(nz-1, zn, xn, yn, scalen); // parameters for last section`

NOTES

Currently navigation functionality not fully implemented (only Contains()). Decomposition in concave polygons not implemented - drawing in solid mode within x3d produces incorrect end-faces
