When a layer is created, previously created layers 3331c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * and the frame buffer still receive every drawing command. For instance, if a 3341c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * layer is created and a shape intersecting the bounds of the layers and the 3351c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * framebuffer is draw, the shape will be drawn on both (unless the layer was 3361c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * created with the SkCanvas::kClipToLayer_SaveFlag flag.) 3371c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3381c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * A way to implement layers is to create an FBO for each layer, backed by an RGBA 3391c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * texture. Unfortunately, this is inefficient as it requires every primitive to 3401c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * be drawn n + 1 times, where n is the number of active layers. In practice this 3411c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * means, for every primitive: 3421c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * - Switch active frame buffer 3431c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * - Change viewport, clip and projection matrix 3441c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * - Issue the drawing 3451c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3461c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * Switching rendering target n + 1 times per drawn primitive is extremely costly. 3476b7bd24659fb175fe1f0e97c86c18969918b496aRomain Guy * To avoid this, layers are implemented in a different way here, at least in the 3486b7bd24659fb175fe1f0e97c86c18969918b496aRomain Guy * general case. FBOs are used, as an optimization, when the "clip to layer" flag 3496b7bd24659fb175fe1f0e97c86c18969918b496aRomain Guy * is set. When this flag is set we can redirect all drawing operations into a 3506b7bd24659fb175fe1f0e97c86c18969918b496aRomain Guy * single FBO. 3511c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3521c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * This implementation relies on the frame buffer being at least RGBA 8888. When 3531c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * a layer is created, only a texture is created, not an FBO. The content of the 3541c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * frame buffer contained within the layer's bounds is copied into this texture 35587a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * using glCopyTexImage2D(). The layer's region is then cleared(1) in the frame 3561c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * buffer and drawing continues as normal. This technique therefore treats the 3571c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * frame buffer as a scratch buffer for the layers. 3581c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3591c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * To compose the layers back onto the frame buffer, each layer texture 3601c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * (containing the original frame buffer data) is drawn as a simple quad over 3611c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * the frame buffer. The trick is that the quad is set as the composition 3621c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * destination in the blending equation, and the frame buffer becomes the source 3631c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * of the composition. 3641c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3651c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * Drawing layers with an alpha value requires an extra step before composition. 3661c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * An empty quad is drawn over the layer's region in the frame buffer. This quad 3671c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * is drawn with the rgba color (0,0,0,alpha). The alpha value offered by the 3681c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * quad is used to multiply the colors in the frame buffer. This is achieved by 3691c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * changing the GL blend functions for the GL_FUNC_ADD blend equation to 3701c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * GL_ZERO, GL_SRC_ALPHA. 3711c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * 3721c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * Because glCopyTexImage2D() can be slow, an alternative implementation might 3731c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * be use to draw a single clipped layer. The implementation described above 3741c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy * is correct in every case. 37587a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * 37687a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * (1) The frame buffer is actually not cleared right away. To allow the GPU 37787a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * to potentially optimize series of calls to glCopyTexImage2D, the frame 37887a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * buffer is left untouched until the first drawing operation. Only when 37987a76578f76f4a6bceb187da6b7a01899ca0d85aRomain Guy * something actually gets drawn are the layers regions cleared. 3801c740bce8a762f02b5283045a0e2de7c8fb41277Romain Guy */ 381d55a86120dd1e8ebcc6906c9ffd463f7460348daRomain Guybool OpenGLRenderer::createLayer(sp<Snapshot> snapshot, float left, float top, 382eb99356a0548684a501766e6a524529ab93304c8Romain Guy float right, float bottom, int alpha, SkXfermode::Mode mode, 383eb99356a0548684a501766e6a524529ab93304c8Romain Guy int flags, GLuint previousFbo) { 384eb99356a0548684a501766e6a524529ab93304c8Romain Guy LAYER_LOGD("Requesting layer %.2fx%.2f", right - left, bottom - top);
