HDR (High Dynamic Range, high dynamic range) HDR was originally only used in photography, photographers take different exposures to the same scene to take multiple photos to capture a wide range of color values. These images are combined into HDR images, which combine different exposure levels to make a wide range of details visible. Look at the following example, the image on the left is full of details in the illuminated area, but nothing can be seen in the dark area, but the high exposure of the image on the right can reveal the dark area that could not be seen before. In WebGL, HDR enables us to represent color values with more than 1. 0 data. So far, we have used LDR (low dynamic range), and all color values have been limited to the [0J1] range. In reality, the color values of light sources such as the sun and lights must be far beyond the range of 1.0. The above is all the content of this article "what is the meaning of HDR in webgl?"
