| 863 | * Layers are viewed by Skia are slightly different than layers in image editing |
| 864 | * programs (for instance.) When a layer is created, previously created layers |
| 865 | * and the frame buffer still receive every drawing command. For instance, if a |
| 866 | * layer is created and a shape intersecting the bounds of the layers and the |
| 867 | * framebuffer is draw, the shape will be drawn on both (unless the layer was |
| 868 | * created with the SkCanvas::kClipToLayer_SaveFlag flag.) |
| 869 | * |
| 870 | * A way to implement layers is to create an FBO for each layer, backed by an RGBA |
| 871 | * texture. Unfortunately, this is inefficient as it requires every primitive to |
| 872 | * be drawn n + 1 times, where n is the number of active layers. In practice this |
| 873 | * means, for every primitive: |
| 874 | * - Switch active frame buffer |
| 875 | * - Change viewport, clip and projection matrix |
| 876 | * - Issue the drawing |
| 877 | * |
| 878 | * Switching rendering target n + 1 times per drawn primitive is extremely costly. |
Romain Guy | 6b7bd24 | 2010-10-06 19:49:23 -0700 | [diff] [blame] | 879 | * To avoid this, layers are implemented in a different way here, at least in the |
| 880 | * general case. FBOs are used, as an optimization, when the "clip to layer" flag |
| 881 | * is set. When this flag is set we can redirect all drawing operations into a |
| 882 | * single FBO. |
Romain Guy | 1c740bc | 2010-09-13 18:00:09 -0700 | [diff] [blame] | 883 | * |
| 884 | * This implementation relies on the frame buffer being at least RGBA 8888. When |
| 885 | * a layer is created, only a texture is created, not an FBO. The content of the |
| 886 | * frame buffer contained within the layer's bounds is copied into this texture |
Romain Guy | 87a7657 | 2010-09-13 18:11:21 -0700 | [diff] [blame] | 887 | * using glCopyTexImage2D(). The layer's region is then cleared(1) in the frame |
Romain Guy | 1c740bc | 2010-09-13 18:00:09 -0700 | [diff] [blame] | 888 | * buffer and drawing continues as normal. This technique therefore treats the |
| 889 | * frame buffer as a scratch buffer for the layers. |
| 890 | * |
| 891 | * To compose the layers back onto the frame buffer, each layer texture |
| 892 | * (containing the original frame buffer data) is drawn as a simple quad over |
| 893 | * the frame buffer. The trick is that the quad is set as the composition |
| 894 | * destination in the blending equation, and the frame buffer becomes the source |
| 895 | * of the composition. |
| 896 | * |
| 897 | * Drawing layers with an alpha value requires an extra step before composition. |
| 898 | * An empty quad is drawn over the layer's region in the frame buffer. This quad |
| 899 | * is drawn with the rgba color (0,0,0,alpha). The alpha value offered by the |
| 900 | * quad is used to multiply the colors in the frame buffer. This is achieved by |
| 901 | * changing the GL blend functions for the GL_FUNC_ADD blend equation to |
| 902 | * GL_ZERO, GL_SRC_ALPHA. |
| 903 | * |
| 904 | * Because glCopyTexImage2D() can be slow, an alternative implementation might |
| 905 | * be use to draw a single clipped layer. The implementation described above |
| 906 | * is correct in every case. |
Romain Guy | 87a7657 | 2010-09-13 18:11:21 -0700 | [diff] [blame] | 907 | * |
| 908 | * (1) The frame buffer is actually not cleared right away. To allow the GPU |
| 909 | * to potentially optimize series of calls to glCopyTexImage2D, the frame |
| 910 | * buffer is left untouched until the first drawing operation. Only when |
| 911 | * something actually gets drawn are the layers regions cleared. |
