Accuracy & dimensional accuracy: Every screw, gasket, flange must be shown to scale - technical target groups immediately recognize discrepancies.
Material & texture representation: Renderings must convey realistic reflection, transparency (e.g. rubber) and surface structure.
Lighting & shadows: Precise lighting shows functional surfaces, ensures technical clarity and emphasizes details - e.g. display, screws or O-rings.
Sectional & exploded views: Make inner workings visible, explain functionality. Particularly common in the field of mechanical engineering.
Animation / movement: Rotating impeller, fluid flow, valve movement - animated renderings show dynamic processes clearly.
