TXTRU Class Reference

A poly-extrusion.

XTRU is a poly-extrusion with fixed outline shape in x-y, a sequence of z extents (segments) and two end faces perpendicular to the z axis. The x-y outline is defined by an ordered list of points; the overall scale of the outline scales linearly between z points and the center can have an x-y offset specified at each segment end.

A TXTRU has the following parameters:

  • name: name of the shape
  • title: shape's title
  • material: (see TMaterial)
  • nxy: number of x-y vertex points constituting the outline – this number should be at least 3
  • nz: number of planes perpendicular to the z axis where the scaling dimension of the section is given – this number should be at least 2
  • Xvtx: array [nxy] of X coordinates of vertices
  • Yvtx: array [nxy] of Y coordinates of vertices
  • z: array [nz] of z plane positions
  • scale: array [nz] of scale factors
  • x0: array [nz] of x offsets
  • y0: array [nz] of y offsets

All XTRU shapes are correctly rendered in wire mode but can encounter difficulty when rendered as a solid with hidden surfaces. These exceptions occur if the outline shape is not a convex polygon. Both the X3D and OpenGL renderers expect polygons to be convex. The OpenGL spec specifies that points defining a polygon using the GL_POLYGON primitive may be rendered as the convex hull of that set.

Solid rendering under X3D can also give unexpected artifacts if the combination of x-y-z offsets and scales for the segments are chosen in such a manner that they represent a concave shape when sliced along a plane parallel to the z axis.

Choosing sets of point that represent a malformed polygon is not supported, but testing for such a condition is not implemented and thus it is left to the user to avoid this mistake.

◆ SplitConcavePolygon()

void TXTRU::SplitConcavePolygon ( Bool_t  split = kTRUE)

(Dis)Enable the splitting of concave polygon outlines into multiple convex polygons.

This would make for better rendering in solid mode, but introduces extra, potentially confusing, lines in wireframe mode.
