....procedural shading systems as well as compilers that automatically generate instructions corresponding to rendering operations on graphics hardware. However, to apply these ideas to other applications, the limited value range and accuracy of graphics hardware have to be considered. Trendall et al. [17] gave several formulas for scaled and biased functions whose value ranges are within the limits and applied the method to the computation of interactive caustics. Some of the above applications scale and shift the variables in their computations so that they fit into the value range of the ....
....textures or written directly to the textures with the render to texture extension. Values in graphics hardware are clamped to either [0, 1] or [ 1, 1] depending on the stage of the graphics pipeline. Therefore, we need to transform the value ranges of all the inputs and outputs. Trendall et al. [17] also mapped the lower bound of the range to 0 by biasing for better accuracy. In contrast, we generally avoid introducing any bias during the mapping. The reason is explained in section 3.2) That is, we only apply scaling to change the numerical ranges. Range scaling can be considered as a ....

.... diagrams [13] flow visualization [14] morphological operations [15] segmentation [16] and many others ( 17] contains a good overview) Although schemes for general computation and especially discrete solvers for partial differential equations in graphics hardware have been previously described [18, 19, 20], the researchers always emphasized the problem of the low number precision and incomplete set of operations which restricted the application area. The new DX9 graphics hardware overcomes these problems by introducing a floating point number format and a set of the most common mathematical ....

....One view of the OpenGL buffers is as a simple processor with little memory (just a few bytes) and a limited instruction set. Recently, techniques for performing general computations using the OpenGL pipeline have been proposed. Two such examples are Peercy et al. 56] and Trendall and Stewart [71]. 4.2 Stencil buffer The stencil buffer is composed of a small set of bits (usually more than 4) that can be used to control which areas of the other buffers, textite.g. color buffer) are currently active for drawing. A common use of the stencil buffer is to draw a piece of static geometry ....
