Thus HDR rendering systems have to map the full dynamic range of what the eye would see in the rendered situation onto the capabilities of the device. This tone mapping is done relative to what the virtual scene camera sees, combined with several full screen effects , e.g. to simulate dust in the air which is lit by direct sunlight in a dark ...
Tone mapped high-dynamic-range (HDR) image of St. Kentigerns Roman Catholic Church in Blackpool, Lancashire, England, UK. Tone mapping is a technique used in image processing and computer graphics to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images in a medium that has a more limited dynamic range.

The Hammer Editor, the engine's official level editor, uses rendering and compiling tools included in the SDK to create maps using the binary space partitioning (BSP) method. Level geometry is created with 3D polygons called brushes ; each face can be assigned a texture which also defines the properties of the surface such as the sounds used ...
These are similar to environment maps, but typically use a very low resolution or an approximation such as spherical harmonics. [42] (Note: Blender uses the term 'light probes' for a more general class of pre-recorded lighting data, including reflection maps. [43])
A display is called an HDR display if it can accept HDR content and map it to its display characteristics, [28] so the HDR logo only provides information about content compatibility and not display capability. Displays that use global dimming, such as most edge-lit LED displays, cannot display the advanced contrast of HDR content.
UV texturing permits polygons that make up a 3D object to be painted with color (and other surface attributes) from an ordinary image. The image is called a UV texture map. [ 1 ] The UV mapping process involves assigning pixels in the image to surface mappings on the polygon, usually done by "programmatically" copying a triangular piece of the ...
High dynamic range (HDR), also known as wide dynamic range, extended dynamic range, or expanded dynamic range, is a signal with a higher dynamic range than usual. The term is often used in discussing the dynamic ranges of images , videos , audio or radio .
