Brief Introduction The Nehe tutorial introduces the trackball technique to us in this lesson. Trackball technology allows users to rotate objects directly using the mouse, which is the most basic function that all interactive 3D software must provide. Powerful bots have been provided in the OSG, including Trackballmanipulator, Firstpersonmanipulator, Drivemanipulator, and so on, which can be used to see th

battery is not used for a long time, please charge and discharge at least two months to ensure its activity. 　　Maintenance of hard disk Either a desktop or a laptop's hard drive is a very delicate thing. Even though the hard drives are now super resistant, they should be prevented from shaking unnecessarily. Due to the notebook computer hard drive mobile problem, its seismic performance has been very good, but should pay attention to move not too fierce, not to knock, of course, it is best no

, can be used for any of the same port.For CPUs like the joystick (or gamepad), it does not wait for the device to send interrupts. Because the joystick is used primarily for games, the movement of the joystick must be very fast, so it is desirable to use polling to detect whether the device requires CPU attention. The disadvantage of using polling is that the CPU is in a busy state because the CPU keeps checking the device multiple times. However, it

already been said, Firefox OS can satisfy developers of hacker dreams, and future development is likely to exceed Mozilla's expectations. In fact, such a situation has occurred. We have ported Firefox OS to devices such as Raspberry Pi and PandaBoard. It's not perfect, but it's interesting enough. It should be noted that such a transplant was implemented prior to the release of the first official version of the Firefox OS. In addition, you can run the Firefox OS via Mac, Windows, and Linux de

code more concise. To get a better user experience, I want the interactive area to be larger, so it's reasonable to have the player click on a column to move the disc. By adding the absolute and relative positions on the appropriate elements, I overlay the controls on the same column with each other. This allows you to select only the bottom round hole in each column. I carefully set the time for each row of the disk to fall, and their time function approximates a two-time curve, similar to the

In the "General" page of the options, "smooth mode" means to increase the frame rate of the game, so that the game at 40 frames per second to display, so that the game's picture smoother. However, if the computer configuration is not good, generally do not check this, so the game will be 20 frames per second to run, that is, the rate is generally reduced to ensure that it can run smoothly.

EditText are inherited from them, so there are few codes in EditText. Let's take a look at the source code of EditText. There is an Override getDefaultEditable method to check whether the name is editable. This method returns true directly. There is also a getdefamovmovementmethod method, which returns ArrowKeyMovementMethod. getInstance (). By viewing the source code of ArrowKeyMovementMethod, it is basically determined that this method is the "culprit" of the ContextMenu and
