OpenCL Kernels can be either executed on the GPU or the CPU. This allows for fallback solutions, where the customer may have a very outdated system. The programmer can also choose to limit their functionality to either the CPU or GPU. To get started using OpenCL, you'll need a 'Context' and a 'Devi...

Each fundamental opencl type has a vector version. You can use the vector type by appending the number of desired components after the type. Supported number of components are 2,3,4,8 and 16. OpenCL 1.0 does not offer three components. You can initialize any vector using two ways: Provide a sing...

To discovery all the available print services, we can use the PrintServiceLookup class. Let's see how: import javax.print.PrintService; import javax.print.PrintServiceLookup; public class DiscoveringAvailablePrintServices { public static void main(String[] args) { discoverPrintS...

To discovery the default print service, we can use the PrintServiceLookup class. Let's see how:: import javax.print.PrintService; import javax.print.PrintServiceLookup; public class DiscoveringDefaultPrintService { public static void main(String[] args) { discoverDefaultPrintSer...

A print job is a request of printing something in a specific print service. It consists, basically, by: the data that will be printed (see Building the Doc that will be printed) a set of attributes After picking-up the right print service instance, we can request the creation of a print job...

The cursor primitive is a reticle that allows for clicking and basic interactivity with a scene on devices that do not have a hand controller. The default appearance is a ring geometry. The cursor is usually placed as a child of the camera. <a-scene> <a-camera> <a-cursor>&...

To add visual feedback to the cursor to show when the cursor is clicking or fusing, we can use the animation system. When the cursor intersects the entity, it will emit an event, and the animation system will pick up event with the begin attribute: <a-entity cursor="fuse: true; fuseTimeout:...

When the active property gets toggled, the component will notify the camera system to change the current camera used by the renderer: var secondCameraEl = document.querySelector('#second-camera'); secondCameraEl.setAttribute('camera', 'active', true);

The camera primitive determines what the user sees. We can change the viewport by modifying the camera entity’s position and rotation. Note that by default, the camera origin will be at 0 1.6 0 in desktop mode and 0 0 0 in VR mode. Read about the camera.userHeight property. <a-scene> <...

$logger = $container->get('logger'); This will fetch the service with the service ID "logger" from the container, an object that implements Psr\Log\LoggerInterface.
