Additional basic objects have been added to Relux to enable more elaborate objects to be modelled.
All the new objects are rotational solids. The angle through which they are rotated (0 < angle ≤ 360°) and the number of segments generated can be specified for all the rotational solids.
The object height is a further parameter that can be set. The object can be made of one or more materials depending on the object type.
Sphere: the sphere is made up of a single material. In addition to the number of segments, it is also possible to specify the number of layers here. A texture is adapted by means of sphere mapping.
Hemisphere: the hemisphere can be made up of two different materials – one for the upper hemisphere and one for the base surface. In addition to the number of segments, it is also possible to specify the number of layers here too. A texture on the hemisphere can be adapted by means of sphere mapping, and a texture on the base surface by means of cuboid mapping.
Cone/truncated cone/pyramid/truncated pyramid: in the case of a cone, a radius can be specified for the base and a radius for the top. If the radius for the top is greater than 0, this is a truncated cone. If a value of 4 is selected for the number of segments, a pyramid or a truncated pyramid will be generated. The cone is made up of a maximum of three different materials: the outside surface and the base and top surface. A texture on the outside can be adapted by means of cylinder mapping and a texture on the base and top surface by means of cuboid mapping.
Ring: the ring is parameterised by means of four radii: the inside radius at the top and the bottom and the outside radius at the top and the bottom. In this way, it is possible to model conical pipes too.
Polygonal rotational objects: in addition to the fixed parameterised rotational objects mentioned above, the rotational solid can also be polygonal.
To generate solids of this type, you use the "Construct rotational solid" tool under "Tools" -> "Construct" -> "Rotational solid".
The polygonal rotational body is made of just one material. When it is generated, there are fundamentally two different ways in which a rotational solid can be created:
Rotation around an axis: first of all, you draw the axis around which the closed polygon is to be rotated. Following this, the rotating polygon is drawn in (this is not permitted to intersect the axis of rotation). The action is completed with a double click or by pressing the enter key.
Rotation around the end points: after selecting the "Construct rotational solid" tool, press the enter key to skip the step for drawing the axis of rotation. The polygon that has been generated can be rotated around its end points by a double click or by pressing the enter key on the keyboard again. What is important here is that the polygon should not intersect its axis of rotation that is defined by its end points.
