This paper presents a fast and easy to implement voxelization algorithm, which is based on the z-buffer. Unlike most existing methods, our approach is suitable both for polygonal and analytical objects. The efficiency of the method is independent of the object complexity and can be accelerated ...
(Note that much of the scene is transparent and thus does not affect the depth buffer.) Mip level 4 is the first whose dimensions (103x111) are not evenly divisible by 2. An alternative method of generating the mip chain The goal of the previously-described algorithm is to preserve depth...

Normal buffer: Store normals vectors of the geometry Then, to calculate shading we just have to combine all these different buffers and perform the calculation. As a side note, there is another interesting rendering algorithm usually used in hand-held devices called TBDF (Tile Based Deferred Rend...
The algorithm outputs the depth map of the current frame in real time. The pixel value of each frame represents the current depth value. The darker the color, the closer it is to the camera, and the whiter the color, the farther it is from the depth.Sample code:...
Our algorithm is implemented using DirectX 9 hardware, which does not allow reading a depth buffer as a texture. We get around this limitation by binding a 32-bit floating-point color buffer during our depth pre-pass. Although we do not require full 32-bit precision, we picked tha...
Perform a Z-buffer scan-conversion and visibility determination of the scene from the perspective of a light source instead of the eye. However, the visibility is simplified in that only the depth information is kept in 2-D grid or map, with no information about the visible objects at all....

An advantage of the present invention is that effective Z data bandwidth through the depth buffer interface is maximized in order to facilitate fast depth buffer access operations.doi:US6961057 B1James M. Van DykeJames E. Margeson IIIJ. Van Dyke, J. Margeson, "Method and apparatus for ...
Moreover, because the LDI data are represented in a single image coordinate system, McMillan’s warp ordering algorithm can be successfully adapted. As a result, pixels are drawn in the output image in back-to-front order. No z-buffer is required, so alpha-compositing can be done ...
