Sample answer:
Achieving Realistic Lighting Effects in Architectural Renderings
To create realistic and accurate lighting effects from different types of weather or atmospheric conditions, architectural renderers employ a combination of techniques:
-
HDRI Maps: High Dynamic Range Image (HDRI) maps provide a realistic representation of the environment, including lighting conditions. They capture the entire range of light values, from bright highlights to dark shadows. By using HDRI maps, renderers can accurately simulate the sun’s position, time of day, and atmospheric effects.
-
Physical-Based Rendering (PBR): PBR is an advanced rendering technique that simulates the way light interacts with materials. By assigning physical properties to materials, such as reflectivity, refraction, and absorption, PBR creates realistic shading and lighting effects.
-
Atmospheric Scattering: Atmospheric scattering refers to the way light is scattered by particles in the atmosphere. This scattering creates effects such as haze, fog, and clouds. Renderers use specific algorithms to simulate these effects, adding depth and realism to their scenes.
