1. AERODYNAMICS in Concept Art
コンセプトアートにおける空気力学
In concept art, understanding physical fundamentals in how air flow interacts with different shapes and surfaces is crucial for depicting dynamic environments and motion. This includes capturing the transition from smooth, laminar flow to chaotic, turbulent flow, which adds realism, credibility and depth to the portrayal of natural forces and their impact on various elements in a scene.
1.1. Understanding Pressure Resistance
圧力抵抗の理解
Pressure resistance, or shape resistance, plays a pivotal role not only in aerodynamic principles but also in illustrating dynamic environments. Imagine depicting a wing slicing through air. Here, pressure resistance sculpts the air's flow, creating high pressure in front and lower pressure behind. Now, consider a wheat field. Each wheat stem sways, influenced by this invisible force. They move uniformly in groups, yet each group moves independently. Meanwhile, in the boundary areas between these groups, wheat stems seem to move chaotically. This scene showcases the pressure differences and air movement, telling a story of direction and magnitude of force; and bringing life tp a scene.
1.2. Interaction between Shape and Resistance
形状と抵抗の相互作用
Shapes interact with air in unique ways, a concept crucial for industrial design and realism in concept art. A cube-like shape, confronting the air flow, creates tension and high air flow resistance. A cylinder, with its rounded shape, illustrates more harmonious motion with less air flow resistance. Finally, the aerodynamically perfect waterdrop shape or a wing shilhouette showcases minimal resistance. Imagine the wheat field scenario – observe how different parts of the field react differently to the wind, creating a tapestry of movement and energy.
1.3. The role of surface topologies on aerodynamics
空気力学における表面トポロジーの役割
Friction resistance comes alive when you depict how air flow interacts with various surface topologies. This could range from the sleek, yet solid surface of a wing to the uneven, yet flexible textures of a wheat field or other organic shapes. The resistance depends on the surface's smoothness and flexibility, as well as on the speed and density of the air flow. In concept art, this is useful to define how air flow creates local and regional waves of motions across different surfaces, bringing a sense of flexibility and dynamics to environmental scenes.
1.4. The impact of laminar to turbulent flow on geometrical order
層流から乱流への移行が幾何学的な秩序に与える影響
Laminar flow, represented by ordered, parallel lines, can be visualized in the way air flows over a hard/soft surface or a geometrical topology like a wheat field, creating a sense of fluidity. But at the transition point to turbulent flow, chaotic movements disrupt the harmony by inducing local stress, pressure and disorder. This offers a compelling narrative tool for depicting a shift in energy and mood in the artwork, or geometrical deformations of shapes.
