Image Based Lighting with Near Light Sources
Recent some researches on realistic computer graphics (CG) focus on synthesis of photographs and virtual objects. Image Based Lighting (IBL) is one of the techniques to generate naturally illuminated images by using photographs. This paper reports a new experiment to render virtual objects into real scenes with near light sources, which have not been considered in original IBL. Our experiment s...
متن کاملLED-based metameric light sources: Rendering the colours of objects and other colour quality criteria
Solid-state white light sources based on multiple light emitting diodes (LEDs) have three features that make them radically different from other sources of electrically generated light. These are the narrowband spectra of the individual LEDs, the possibility of controlling the light output of the individual LEDs and the limited stability of the LED’s colour. These features make it possible to a...
متن کاملA Two-metric Proposal to Specify the Color-rendering Properties of Light Sources for Retail Lighting
Lighting plays an important role in supporting retail operations, from attracting customers, to enabling the evaluation of merchandise, to facilitating the completion of the sale. Lighting also contributes to the identity, comfort, and visual quality of a retail store. With the increasing availability and quality of white LEDs, retail lighting specifiers are now considering LED lighting in stor...
متن کاملModeling the Spatial Energy Distribution of Complex Light Sources for Lighting Engineering
In lighting engineering the precise simulation of a lighting project requires a light source model which has the ability to reproduce real light sources. The models which assume the spatial energy is diiused over the light source, are not suuciently precise, since real light sources do not have uniform spatial energy distributions. Other models based upon gonio-photometric diagrams provided by ...
متن کاملPerformance Comparison of Techniques for Approximating Image-Based Lighting by Directional Light Sources
Image-Based Lighting (IBL) has become a very popular approach in computer graphics. In essence IBL is based on capturing the illumination conditions in a scene in an omni-directional image, called a light probe image. Using the illumination information from such an image virtual objects can be rendered with consistent shading including global illumination effects such as color bleeding. Renderi...
