Adding second argument in a C++ function prevents OpenGL from drawing?


It could possibly be a memory corruption bug, and by adding the extra parameter you are subtly changing the layout of data in memory and causing the bug to have a visible effect, where before you were getting away with it - i.e. you were still overwriting memory, but happened to be overwriting something unimportant.

Normally your function would be removed by the compiler because it does nothing, however I'm guessing you are compiling in debug mode and so it may not optimize it away.

Automatic adding the common part to function of a class without explicitly adding those to every function
You can define two methods that do the common logic, for example - preProcess() and postProcess(). If the methods that execute this common logic are instnace methods of ObjectUtils, you can even override the common methods in sub-classes of ObjectUtils if you want to alter the common logic. If the methods that share the common logic are static methods, preProcess() and postProcess() would also b

Drawing new Kinetic JS polygon with click function
You've almost got it...just be sure to add the new sq1 to the layer and also layer.draw var stage = new Kinetic.Stage({ container: 'container', width: 750, height: 750 }); var layer = new Kinetic.Layer(); stage.add(layer); var sq1 = new Kinetic.Rect({ x: 25, y: 100, width: 200, height: 200, fill: '#000000', draggable: true }); lay

Passing the weights argument to a regression function inside an R function
You have two problems. The error you're encountering is because you're trying to use the weigh variable without referencing it as coming from the mydata dataset. Try using mydata$weig. This will solve your first error, but you then get the actual one related to using the weights argument, which is: Error in model.frame.default(formula = formula, data = data, weights = substitute(weights), : inv

iOS drawing goes wrong when drawing view is transformed
You will need to apply the same transforms to your points when you redraw the line. The points you have stored in your array is relative to the canvas it was rendered on. I suggest you store the original frame and then scale the coordinates between the original frame and the new size on the next line render.

Using OpenGL for Image Processing - Setting up an OpenGL context
You don't have to use a GLSurfaceView. GLSurfaceView is a convenience class written purely in Java. It simplifies the setup part for applications that want to use OpenGL rendering in Android, but all of its functionality is also available through lower level interfaces in the Android frameworks. For purely offscreen rendering, you can use the EGL interfaces to create contexts, surfaces, etc. Some
