HDRI是High-Dynamic Range (HDR) image的缩写,就是为了解决这个问题而发明出来的,简单说,HDRI是一种亮度范围非常广的图像,它比其它格式的图像有着更大亮度的数据贮存,而且它记录亮度的方式与传统的图片不同,不是用非线性的方式将亮度信息压缩到8bit或16bit的颜色空间内,而是用直接对应的方式记录亮度信息,它可以说记录了图片环境中的照明信息,因此我们可以使用这种图像来“照亮”场景。有很多HDRI文件是以全景图的形式提供的,我们也可以用它做环境背景来产生反射与折射。这里强调一下HDRI与全景图有本质的区别,全景图指的是包含了360度范围场景的普通图象,可以是JPG格式,BMP格式,TGA格式等等,属于Low-Dynamic Range Radiance Image,它并不带有光照信息。
Picture Lights for HDR Light Studio 4
HDR Light Studio is an interactive tool for creating custom HDR environment maps for image based lighting of CG scenes. Work with a dynamic HDR canvas where Synthetic and Picture based light sources are positioned, scaled, colored all on fly on the HDRI. Accomplish all these lighting tasks in real-time directly on your 3D model. Instant lighting feedback - a totally interactive lighting tool. Picture Lights add photographically captured studio lighting and other image based lighting and effects to HDR Light Studio, including: soft boxes, spot lights, real windows, and much more. Picture Lights are high resolution (4k) HDR images that include an alpha channel for their transparency - they are perfect for super realistic lighting and reflections and remain high quality even in very high resolution HDRI maps. Picture Lights can also be colorized!
