Introduction to Image-based Lighting
High Dynamic Range Images (HDRIs) have been used for many years to light computer renderings. HDRIs are a mature technology with almost all 3D renderers now supporting fast and efficient rendering using image-based lighting. In fact, most real-time rendering software relies on HDRIs as the main source of lighting and reflections. But why have HDRIs become such an important part of the CG lighting toolkit? The answer is realism.
HDR lighting images capture a lot of useful information that is stored by each pixel as color and brightness values. Surrounding a 3D computer model with this data generates the brightness and color of the illumination coming from all directions and provides all the reflections seen by the 3D model. A bright light in a HDRI creates a bright reflection, and a bright reflection creates bright illumination from that direction. The lighting and reflections are therefore hard-wired together in a HDRI. This is why renderers using photo-real materials and HDRI lighting can create amazingly realistic results that are photographic and truly believable as real and not computer generated.
Static HDRI Environments
Historically, HDR lighting has been provided by static HDR images captured photographically with time consuming techniques or by using expensive specialized HDRI photographic hardware, like a Spheron camera. This made sense, as image-based lighting has traditionally been used to visualize CG objects in a specific real-world environment, such as a CG car being visualized on a stretch of road or in the countryside.
HDR Light Studio 2.0 - Interactive HDRIs
But why should HDRIs be restricted to static environments? Could image-based lighting evolve and become even more useful? Could HDRI lighting techniques become as flexible as CG lighting so lights can easily be moved and adjusted? The answer is yes!
HDR Light Studio 2.0 provides a sophisticated real-time HDRI lighting design tool that 3D artists and designers can use to quickly design studio lighting or to enhance existing static HDRI environments. HDRIs have become interactive, and this provides a totally new way to light your models! If this sounds exciting, then checkout the full list of HDR Light Studio 2.0 features.
