MAKING THE SEEDS: 1. Creating the shape of a seed: a seeds is modeled based on a standard sphere primitive, slightly deformed with a Noise modifier to achieve a higher level of realism. 2. Applying the material to the seeds: the material applied to the seeds is intended to give them an icy effect. Resembling white pearls, they contrast against the background of the fine velvet petals. 3. Creating the material: the setting in Material Editor are shown in the figure in Step 3.

PETAL CREATION PROCESS: There are two main methods for modeling the petals as follows: 1. Surface modeling method: draw a 2D surface of suitable shape using the Create > Line tool and a volume to the surface using the Shell modifier. Edge softening is achieved with MeshSmooth modifier. 2. Using Symmetry Modifier: if we are aiming for absolute symmetry of the two halves of the petal, we must use the Symmetry, but this step must precede MeshSmooth. 3. Solid modeling method: place a standard Plane primitive in the workspace (Perspective Viewport). The desired shape is obtained by selecting and moving vertices. The remaining steps of shaping the desired form are analogous to those of the method described at the beginning of the tutorial. 4. Clone the petals: using Pivot > Affect Pivot Only, where by default the pivot point is at the center of the base of the object. In this case, a total of five rows of four petals are modeled. They mus be grouped by Group so that they do not move during further work.

CHARACTER ANIMATION PROCESS: 1. A selection of a pose: from Pose & Animate. Movements in DAZ Studio can be animated based on ready-made body positions or by the designer's idea. A pose can be selected from Presets and applied to the model by dragging. 2. A selection of built-in animations: they are grouped into several groups and are selected from a dropdown menu below the workspace. For example the "knee-idle-g8f" motion is placed in aniMate2. There is an option to add additional settings, such as to set the duration of the movement Add Length by a double-clicking on it. In order to get a beautiful animation, it is necessary to select or create a suitable combination of movements with a smooth transition between them. 3. A selection of facial expression: from the group "expression".

The aim of the practice is to use the capabilities of the software to create realistic 3D models of characters. The main steps are as follows: 1. A selection of „Interface Layouts”: from Window > Workspace > Select Layout > „Hollywood Blvd”. "Hollywood Blvd" includes several activities ("Activities"), initially starting with the first - Actors, Wardrobe & Props. The Smart Content Pane opens and then select Files. 2. Place a character in the scene: from Files > Figures > Creatures/People. After selecting the desired character, it is placed in the workspace (Viewport) by dragging (with the left mouse button pressed) or double-clicking. In this example the model selected is Genesis 8 Basic Male. 3. A selection of clothing and accessories: from Files > Wardrobe. If a change is required subsequently, it is necessary to select that part of the clothing to be deleted. This is done using the Surface Selection Tool and then press Delete. 4. Fitting the clothing: it is necessary to make a correction if the clothing does not cover the body properly when it is directly placed on the model. This part ot the clothing is selected and from the panel on the right select Fit to and press the None button. In the window that appears, select Genesis 8 Male from the drop-down menu and press the Accept button. If an Auto-Fit:... window appears, it is necessary to specify for which model the specific garment is originally intended. There is an option to select just a piece of clothing and click on Parameters, from where the size and position of the selected item can be edited precisely using the Scale and Translate options. A similar procedure is used when parts of the character's body (hair, facial features, body structure) need to be edited. 5. A transformation of the base model: it is necessary to select the entire model with the clothing using Region Navigator Tool. The base model can be transformed with help from Actor, Wardrobe & Props For this purpose, Editor and Shaping must be active. 6. Rendering the scene: use the editor (Editor), which is located in the right panel. If the software is installed on a computer with a 64-bit version of Windows, then it can work with Engine: NVIDIA Iray (not supported on a 32-bit version). Select Render > Editor: Render Mode > Photoreal/ Interactive and then click the Render button and select a graphic file format.

Open Material Editor (hotkey "M"): the main settings of the material (ambient, diffuse, glossiness and specular level) are shown in Step 1. 2. Coloring the inner sphere: it should contrast to bring out the golden material of the outer grid. An example is given in Step 2. 3. Adding lights and shadows: this is one of the most complex stages of modeling in 3DS Max, usually done right before animating the model. It should be noted that lights can also be animated. They are selected from the main menu Create > Light. The favorite light of the author is Omni. Each of the lights can be adjusted appropriately to produce realistic shadows and highlights.

Their advantage is that they move in all directions, and most often this happens with changes in the center of gravity. Some models use a system of counterweights, which helps to stay still on slopes with an inclination of 33° (Pico Rover). Some are used to study the environment, others - on the lunar surface. They are usually equipped with a high-resolution camera. The robot is tentatively named by the author VESPER-006 ("Vesper" means Venus) due to the fact that the planet Venus is a "double" of the Earth due to the close dimensions, although the surfaces of the two planets are completely different. The spherical shape was purposefully chosen to make the robot to resemble the planet it was inspired by. VESPER-006 is thought to be with an innovative design and drive method. It is suitable for research and analysis of the environment regardless of what it is (air, liquid or field). The temperature range is also wide (between -40 and +120°C). The mechanism must be able to reach the point with coordinates (x, y, z) in time space [t]. The design is stylish, simple and facilitates the rotation of the robot around its axis, as well as its movement in space. The dimensions must be such that they can take the weight of the engine and equipment. Apart from an aesthetic purpose, to make the design more interesting, the three side elements (Stands) have been added for their practical function - to stabilize the robot when it is in a static position. The main steps in the modeling process are as follows: 1. Modeling the side element: first a curve with the desired shape is drawn using Create > Shapes > Line. After that it is extruded by Modifier Panel > Extrude tool. To edit the object, right-click on it and select Convert to Editable Poly. The model can be modified by selecting individual polygons, edges or vertices and using the Extrude and Bevel tools. 2. Clone the side element: by right-clicking on it and selecting Clone. 3. Modeling the spherical body: the outer Geosphere is transformed into a grid by selecting all polygons, Inset and Extrude. The selected polygons should be removed.

The aim of this practice is to build a printable model of the “HARMONY” laboratory (ISS Module), which means that it is advisable to avoid too much detail, i.e. the level of abstraction should be medium, not high. The main steps are as follows: 1. Modeling the body: transform a cylinder by drawing the figure shown in step 1 using Sketch > Polyline, Three Point Arc, or Spline on the top base of the primitive. Finding the center of the base is done by Sketch > Project and clicking on it. The hole in the center is modeled by Construct > Extrude after drawing a circle. Before constructing the cylindrical hole by pushing in the center part of the top base, the top part of the cylinder can be cut by Construct > Subtract and after copying with Ctrl+C/ Ctrl+V, it can be placed in the bottom part of the cylinder. Its rotated by the Move/Rotate tool by 180° along the relevant axis. The opening on the bottom base is constructed by drawing a 2D profile with the appropriate shape and rotating it along the vertical axis using the Construct > Revolve tool by 360°. 2. Clone the figure on the upper surface: the figure must then be copied a specified number of times using the Circular Pattern. 3. Modeling an additional component: it is constructed by transforming a cylinder 3 mm high and 20 mm in diameter, drawing curves on its upper base using the method described in step 1.

This tutorial is suitable for designers who have a basic knowledge of using the open source product Autodesk 123D Design. The steps to build a Breitenberg vehicle are as follows: 1. Modeling a wheel: a cylinder with a diameter of 2 cm and a height of 0.5 cm is placed in the workspace. Drill a hole in it by drawing a circle with a diameter of 0.3 cm and extruding - 0.5 cm with the Extrude tool. We soften the edges of the cylinder with Fillet Radius: 0.5. 2. Clone the wheel: rotate the resulting wheel 90° along the Z axis and copy it with Ctrl+C and Ctrl+V. 3. Modeling the vehicle body: regarding the design of the vehicle body, there are various options. In this case the author models a classic vehicle, which is most often shown in the bibliographic sources. After drawing and extruding a surface with the desired shape we apply Fillet with radius 35 on the back edge and with 30 on the front edge for a contemporary design (i could provide more images if it is needed). On the selected side edges we successively apply Fillet with a radius of 9. 4. Make a special place for the sensor: it is necessary to select the square plane that is located in the middle of the case and successively apply Sketch > Project, Sketch > Offset and Construct > Extrude with a negative value.
