A Solution to Inverse Interpolation in Computer Graphics
نویسنده
چکیده
Inverse solutions to interpolation techniques in computer graphics may increase the accuracy of the rendered frames. An example is the use of an arbitrary time stamp in time interpolation to evaluate the t-parameter, which in turn can be used for time-variant spatial interpolation. In this paper, an analytic inverse is presented for a shape-preserving piecewise cubic Hermite interpolant, used in context with camera trajectory interpolation. Keywords-LPCHIP; PCHIP; polynomial equation; spline

متن کاملQuality Improvement for Indirect Illumination Interpolation
As the demand for realism in computer graphics grows, the proper account of indirect lighting in image synthesis applications becomes more and more important. However, limitations in available processing power make full solution to Kajiya’s rendering equation [6] largely intractable and stimulate research in irradiance interpolation schemes. In this paper we introduce a quality refinement to Wa...
متن کاملDirectional Stroke Width Transform to Separate Text and Graphics in City Maps
One of the complex documents in the real world is city maps. In these kinds of maps, text labels overlap by graphics with having a variety of fonts and styles in different orientations. Usually, text and graphic colour is not predefined due to various map publishers. In most city maps, text and graphic lines form a single connected component. Moreover, the common regions of text and graphic lin...
متن کامل2D Texture Refinement Using Procedural Functions
In Computer Graphics, aliasing is a problem which is always present when discrete elements are mapped to continuous functions or vice-versa. Although there is no general solution for this kind of problem, there are many techniques that aim at reducing the effects of aliasing. This work first discusses how interpolation methods are usually applied in order to correct this problem and shows the l...
