Tim Duncan (Intel) píše:A few years ago, in Adobe’s Creative Suite* 4 release of Photoshop (Photoshop CS4), Adobe developers focused their OpenGL efforts on enhancing the Canvas and 3D interactions. They implemented Smooth Zoom, Panning, Canvas Rotate, Pixel Grid, and 3D Axis/Lights using the OpenGL API to improve the performance. Turn these features ON (in Preferences), enable “Use Graphics Processor, select the “Advanced Settings” button, select “Advanced Drawing Mode” from the dropdown menu, and enable the checkboxes for “Use Graphics Processor to Accelerate Computation” and “Use OpenCL.“ Refer to Figure 1 and Figure 2 for recommended settings in the Photoshop user interface.

With Photoshop CS5, the developers used OpenGL to speed up the user interface (UI) and to add the Pixel Bender plug-in. The specific UI features targeted were the Scrubby Zoom, HUD Color Picker, Color Sampling Ring, Repousse, and 3D Overlays. With these new features, the OpenGL modes were expanded to encompass basic, normal, and advanced methods.

Then in Photoshop CS6, the team enhanced content editing with standards-based features from both OpenGL and OpenCL. Developers added Adaptive Wide Angle, Liquify, Oil Paint, Puppet Warp, Lighting Effects, and 3D Enhancements using OpenGL. The OpenCL standard was used to add a Field/Iris Tilt/Shift function as well as the Blur function.
