3D Lighting
Different lighting scenarios can dramatically change the tone or mood of any room, both in real world photography and in the 3d rendering world. 3d lighting is therefore a very important consideration in the design process as different temperatures of lights give off different colour values which in turn work hand in hand with the colour of the surface they are influencing.
Skyscape Visualizations knows and understands the importance of the lighting phase as without doing this correctly, the modeling and texturing phases could all as well have been irrelevant if you have weak lighting setups.
Lighting is the breaking point of any render’s quality, showing the big difference between a professional artistic studio and an untrained 3D operator. Performing accurate diffusion of light is a must in producing a the high quality, real world lighting schemes.
For 3D exteriors, the lighting system we use is a skylight or a daylight system where the time of day can be adjusted to accurately simulate where light and shadow would fall at a given time in the day. Global Illumination rendering is used to scientifically
determine the diffusion, reflection and refraction of light needed for photo-realism in the 3d scene. HDRI (High Dynamic Range Images) of the area can be taken on site to replicate the real world lighting scenario, especially important if the 3D model is to be
re-inserted into an image or footage of the surroundings
3D Interior design lighting can be achieved with a combination of using IES (Illuminating Engineering Society) lighting and ‘natural’ skylight for day time scenes. IES is an industry standard where the exact specifications of the lights can be replicated for use in the computer generated environment.
What sets Skyscape Visualizations’ texturing apart from other studios?
Another great 3d lighting technique for architectural visualization is called a sun study. To create a sun study, we first set the path and direction of the sun which are determined, by the exact geographical location and direction of the sun in relation to where the architectural development lies. Once this is established we can observe its effects at different times of the day within the 3d scene, giving us an accurate representation of where the light and shadow of the sun will fall at any given time of the day.
Breathtaking time-lapse effects can be achieved when using this technique as we can observe the light moving from its early morning dawn position up to its high noon and back down to its evening dusk all the way to night time, all while the sky and rays change colour dependant on its position and time of day. Secondary electric powered lighting fixtures can also be turned on and off to influence in the 3d virtual scene, especially as the scene enters night time.
