Measuring this zero penetration velocity (v 0) must take into account variability in armor performance and test variability. Ballistic testing has a number of sources of variability: the armor, test backing materials, bullet, casing, powder, primer and the gun barrel, to name a few. Variability reduces the predictive power of a determination of V0.
The Z-buffer and stencil buffer often share the same area in the RAM of the graphics hardware. In the simplest case, the stencil buffer is used to limit the area of rendering (stenciling). More advanced usage of the stencil buffer makes use of the strong connection between the Z-buffer and the stencil buffer in the rendering pipeline. For ...
Z-buffer, by comparison, is comparatively expensive, so performing primary and secondary visibility tests relieve the z-buffer of some duty. The granularity of a z-buffer has a great influence on the scene quality: the traditional 16-bit z-buffer can result in artifacts (called "z-fighting" or stitching) when two objects are very close to each ...
Z-fighting which cannot be entirely eliminated in this manner is often resolved by the use of a stencil buffer, or by applying a post-transformation screen space z-buffer offset to one polygon which does not affect the projected shape on screen but does affect the z-buffer value to eliminate the overlap during pixel interpolation and comparison ...
Alternatively one can give the stencil buffer a +1 bias for every shadow volume the camera is inside, though doing the detection can be slow. There is another potential problem if the stencil buffer does not have enough bits to accommodate the number of shadows visible between the eye and the object surface, because it uses saturation arithmetic.
stencil; alpha; window ID; As a scene is drawn, drawing primitives (the basic elements of graphics output, such as points, lines, circles, text etc. [1]) are rasterized into fragments which are textured and combined with the existing frame buffer. How a fragment is combined with the data already in the frame buffer depends on various settings.
Nail buffing is the act of polishing the nail using buffers of successively finer grit in order to make nails look more consistent and shiny. [1] A paste is used to fill ridges on nail surfaces. [2] Buffing is also done prior to the application of nail products or artificial nails to help the product adhere to the nail.
Dragon Skin became the subject of controversy with the U.S. Army over testing it against its Interceptor body armor. The Army claimed Pinnacle's body armor was not proven effective. In test runs for the Air Force there were multiple failures to meet the claimed level of protection. This coupled with poor quality control (over 200 of the 380 ...
