Main subject: 3D isometric full-process smart factory scene, including industrial robotic arms, automated production lines, holographic data dashboards, logistics trucks, industrial plant buildings, no text. Scene: Digital twin smart factory in a night environment, with circuit-like glowing lines on the ground, overall presenting the digital interconnection status of the industrial internet. Style: Tech-feel isometric 3D rendering style, integrating digital light effects and industrial realistic elements, with cyberpunk tech atmosphere. Tone: Dark navy blue as the main background color, paired with cool tech blue and data orange as two main light colors, creating a warm-cool contrast. Lighting: Device self-illumination and line light effects as main light sources, overall dark tech lighting, holographic dashboards and production lines emit soft blue glow, ground reflects clear light track reflections. Composition: Oblique top-down isometric perspective composition, elements extending along lines to the depth of the frame, strong sense of depth, holographic dashboard located at the upper right of the frame as the visual focus. Use case: For concept promotion and tech display of Industry 4.0, intelligent manufacturing, digital twin, smart factory, industrial internet and other themes.
