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.
