Despite the factthat photography, film and 3D animation provides photorealistic images to us, they have some confines.3D architectural visualization process allows professionals to make compositive images with photo-realistic quality that provide a comprehensive visualization of the project. The image may help viewers to make out thepurpose of the project and the design of the building interior and exterior in an effective manner.
Lighting.
Lighting effects play an important role in improving the quality of photo-realism of
the model, so it is required to apply lighting effects to the model when an architectural model become photo-realistic by executing the 3D rendering process. When the lighting effect is attached, the important factors like physical accuracy, position of light sources and authenticity of light sources need to be considered. Using 3D visualization technique give us a possibility to make ready daylight as well as night view of the building model. Therefore, viewers can readily understand how the building will look in different time of a full day. For performing the requirements of lighting effect, HRD light probes using with advanced refinement radiosity. The images created by fulfilling architectural visualization process are very attractive and eye appealing. Moreover, the calculation time is proportional to the number of samples per patch.
Texturing.
When experts add textures to the model, they for the most part focus on the color, diffuse, luminosity, glossiness, reflection, refraction, transparency and bump aspects. All these superficial properties are resolved in the surface editor of the 3D rendering software agreed according to customer requirements.
3D Rendering.
The easiest and automated way to make everything photo-realistic by adding suitable color, texture, lighting effects, texture and shade is the computerized 3D rendering process. A light probe is used to obtain a highly effective panoramic radiance map near the location where the building will be rendered. In essence, the light probe is a camera, focused at a mirrored sphere and a configuration used for purchasing environment maps. With the support of photogrammetry and 3D scanning process, a geometric model of the scene is developed and the model is located with radiance values that are measured using light probe. The distant external scene, internal scene and synthetic object become photo-realistic with global illumination and the image view is made similar to the background plate. The outputs are combined into the background plate by using 3D visualization techniques.
It is possible to get a lifelike view of a building before it will be constructed with help of 3D architectural visualization process. Therefore, it is very significant for any kind of building project.
