bicubic filtering in fewer taps

15 Aug 2015 In the last post we saw how to do cubic interpolation on a grid of data. Bicubic interpolation can also used in realtime rendering to make textures look nicer when scaled than A small tutorial about how to load a bitmap file 2 Feb 2011 23 Oct 2012 The trouble with naively implementing Bicubic filtering in a shader is that you end up doing sixteen texture taps. That's rather inefficient. This chapter could be named "Mr. Miyagi's fence lesson." Previously . GLSL also has some unique native interpolation functions that are hardware accelerated. 6 Aug 2011 In addition to OpenGL interpolation types, here different versions of Bi-Cubic . BiCubic() function gets a texture coordinate (x,y) and returns the .. www.cambridgeincolour.com/tutorials/image-interpolation.htm 14 May 2013 All demos of this tutorial are included in GLSL Hacker Code Sample Pack in the GLSL Hacker - OpenGL 3.2 interpolation qualifiers - smooth. I decided to take a minute to dig my old Perforce activities and found the missing cubic() function; enjoy! :) vec4 cubic(float v) { vec4 n = vec4(1.0, 2.0, 3.0, 4.0) - v; In computer graphics and digital imaging, image scaling refers to the resizing of a digital image. Bicubic interpolation yields substantially better results, with only a small increase in It is standard in many frameworks such as OpenGL.17 Dec 2014 I ended up implementing a very simple bicubic texture filtering shader and . I have a bicubic shader which also does manual (linear) filtering 29 Jul 2014 In this OpenGL ES pixel shaders tutorial, take a deep dive into GLSL and This is a 3x3 neighborhood averaging filter, which simply smooths a
