iPhone board game: OpenGL ES or CoreGraphics? [closed]

http://stackoverflow.com/questions/1082511/iphone-board-game-opengl-es-or-coregraphics

you'll get horrible performance. I'd suggest drawing the discrete elements of the game board pieces counters board squares etc. as individual UIViews or CALayers then animating those layers or views around. UIViews aren't too much heavier than..

Fragment Shader - Average Luminosity

http://stackoverflow.com/questions/12168072/fragment-shader-average-luminosity

factor of two used for mipmaps. I did this by sampling from four texture locations that were in the middle of the four squares of four pixels each that made up a 4x4 area in the higher level image. This takes advantage of hardware texture interpolation..

http://stackoverflow.com/questions/15701125/split-the-image-into-a-mesh-of-small-quadrangles-in-opengles

this question Can you explain more detailed What quadrangles would you like to use Are they simple rectangles or squares Or they are a bit more complicated like parallelogram trapezoid kite or rhombus Anyway it's easy to split an image into..

a circle with your hand holding the iPhone the app would be able to redraw it on the screen. This could also work with squares or even more complicated shapes. The only example of application I've seen doing such a thing is AirPaint http vimeo.com..

How to display an image on a MKOverlayView?

data which gives the earthquake risk for 0.5 by 0.5 degree areas and maps them. Your radar data looks similar based on squares. The sample code has a full application called HazardMaps which takes this data and creates an overlay using MKMapPoints...

How can I improve the performance of my custom OpenGL ES 2.0 depth texture generation?

http://stackoverflow.com/questions/6051237/how-can-i-improve-the-performance-of-my-custom-opengl-es-2-0-depth-texture-gener

opaque geometry to block pixels that would never be rendered. To do this I enable depth testing and then draw out the squares that make up the objects in my scene shrunken by sqrt 2 2 with a simple opaque shader. This will create inset squares covering.. squares that make up the objects in my scene shrunken by sqrt 2 2 with a simple opaque shader. This will create inset squares covering area known to be opaque in a represented sphere. I then disable depth writes using glDepthMask GL_FALSE and render.. based on per pixel depth values. This is depicted in my crude illustration below In this example the opaque blocking squares for the top two impostors do not prevent any of the fragments from those visible objects from being rendered yet they block..
