iphone Programming Glossary: interpolationOpenGL ES 2.0 texture distortion on large geometry GL_REPEAT http://stackoverflow.com/questions/11370074/opengl-es-2-0-texture-distortion-on-large-geometry-gl-repeat share improve this question This is the usual texture atlas problem. There is no setting to limit the linear interpolation in mid texture. That's how the hardware works. You can work around the issue by using nearest filter texture lookup in a..
Fragment Shader - Average Luminosity http://stackoverflow.com/questions/12168072/fragment-shader-average-luminosity of four pixels each that made up a 4x4 area in the higher level image. This takes advantage of hardware texture interpolation to average the four sets of four pixels then I just had to average those four pixels to yield a 16X reduction in pixels..
Animating a shape with CoreAnimation http://stackoverflow.com/questions/1767401/animating-a-shape-with-coreanimation animate the path property from that starting value to your final path. Core Animation will perform the appropriate interpolation of the control points in the path to animate it between those two states more if you use a CAKeyframeAnimation . Note that..

UIView scaling during animation http://stackoverflow.com/questions/818207/uiview-scaling-during-animation CA has a private representation of all layer properties and their values changing over time. That's where the frame interpolation is happening and you can't be notified of changes to that as they happen. So the only way is to use an NSTimer or performSelector..
