| 727 | * Layers are viewed by Skia are slightly different than layers in image editing |
| 728 | * programs (for instance.) When a layer is created, previously created layers |
| 729 | * and the frame buffer still receive every drawing command. For instance, if a |
| 730 | * layer is created and a shape intersecting the bounds of the layers and the |
| 731 | * framebuffer is draw, the shape will be drawn on both (unless the layer was |
| 732 | * created with the SkCanvas::kClipToLayer_SaveFlag flag.) |
| 733 | * |
| 734 | * A way to implement layers is to create an FBO for each layer, backed by an RGBA |
| 735 | * texture. Unfortunately, this is inefficient as it requires every primitive to |
| 736 | * be drawn n + 1 times, where n is the number of active layers. In practice this |
| 737 | * means, for every primitive: |
| 738 | * - Switch active frame buffer |
| 739 | * - Change viewport, clip and projection matrix |
| 740 | * - Issue the drawing |
| 741 | * |
| 742 | * Switching rendering target n + 1 times per drawn primitive is extremely costly. |
Romain Guy | 6b7bd24 | 2010-10-06 19:49:23 -0700 | [diff] [blame] | 743 | * To avoid this, layers are implemented in a different way here, at least in the |
| 744 | * general case. FBOs are used, as an optimization, when the "clip to layer" flag |
| 745 | * is set. When this flag is set we can redirect all drawing operations into a |
| 746 | * single FBO. |
Romain Guy | 1c740bc | 2010-09-13 18:00:09 -0700 | [diff] [blame] | 747 | * |
| 748 | * This implementation relies on the frame buffer being at least RGBA 8888. When |
| 749 | * a layer is created, only a texture is created, not an FBO. The content of the |
| 750 | * 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] | 751 | * 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] | 752 | * buffer and drawing continues as normal. This technique therefore treats the |
| 753 | * frame buffer as a scratch buffer for the layers. |
| 754 | * |
| 755 | * To compose the layers back onto the frame buffer, each layer texture |
| 756 | * (containing the original frame buffer data) is drawn as a simple quad over |
| 757 | * the frame buffer. The trick is that the quad is set as the composition |
| 758 | * destination in the blending equation, and the frame buffer becomes the source |
| 759 | * of the composition. |
| 760 | * |
| 761 | * Drawing layers with an alpha value requires an extra step before composition. |
| 762 | * An empty quad is drawn over the layer's region in the frame buffer. This quad |
| 763 | * is drawn with the rgba color (0,0,0,alpha). The alpha value offered by the |
| 764 | * quad is used to multiply the colors in the frame buffer. This is achieved by |
| 765 | * changing the GL blend functions for the GL_FUNC_ADD blend equation to |
| 766 | * GL_ZERO, GL_SRC_ALPHA. |
| 767 | * |
| 768 | * Because glCopyTexImage2D() can be slow, an alternative implementation might |
| 769 | * be use to draw a single clipped layer. The implementation described above |
| 770 | * is correct in every case. |
Romain Guy | 87a7657 | 2010-09-13 18:11:21 -0700 | [diff] [blame] | 771 | * |
| 772 | * (1) The frame buffer is actually not cleared right away. To allow the GPU |
| 773 | * to potentially optimize series of calls to glCopyTexImage2D, the frame |
| 774 | * buffer is left untouched until the first drawing operation. Only when |
| 775 | * something actually gets drawn are the layers regions cleared. |
