UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...
Blender is available for Windows 8.1 and above, and Mac OS X 10.13 and above. [243] [244] Blender 2.80 was the last release that had a version for 32-bit systems (x86). [245] Blender 2.76b was the last supported release for Windows XP, and version 2.63 was the last supported release for PowerPC.
This software is commonly used for desktop recording, gameplay recording and video editing. Screencasting software is typically limited to streaming and recording desktop activity alone, in contrast with a software vision mixer, which has the capacity to mix and switch the output between various input streams.
It is possible to modify the depth map test to produce shadows with a soft edge by using a range of values (based on the proximity to the edge of the shadow) rather than simply pass or fail. The shadow mapping technique can also be modified to draw a texture onto the lit regions, simulating the effect of a projector. The picture above captioned ...
The 4-bit per pixel (4bpp) format supports 16 distinct colors and stores 2 pixels per 1 byte, the left-most pixel being in the more significant nibble. [5] Each pixel value is a 4-bit index into a table of up to 16 colors. The 8-bit per pixel (8bpp) format supports 256 distinct colors and stores 1 pixel per 1 byte.

Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique [1] [2] used to turn objects, often irregularly shaped, into display surfaces for video projection. The objects may be complex industrial landscapes, such as buildings, small indoor objects, or theatrical stages.
On November 10, 2010, SMPTE published SMPTE EG 432-1:2010, which includes a variant of the color space using a D65 white point (about 6503.51 K) instead of the ~6300 K white point of DCI-P3. [7] On April 6, 2011, SMPTE published SMPTE RP 431-2:2011 which defines the reference viewing environment.
