VkFramebuffer + VkRenderPass defines the render target. Render pass defines which attachment will be written with colors. VkFramebuffer defines which VkImageView is to be which attachment. VkImageView defines which part of VkImage to use. VkImage defines which VkDeviceMemory is used and a format of the texel. Or maybe in opposite sequence: VkDeviceMemory is just a … Read more
I’ve had success with the following few experiments. First, find out if X is using TrueColor RGB padded to 32 bits (or just assume this is the case). Then find out if you have write permission to fb0 (and that it exists). If these are true (and I expect many modern toolkits/desktops/PCs might use these … Read more
There are two core pieces to Android graphics: SurfaceFlinger and Skia. SurfaceFlinger is Android’s compositor, used by the window manager to create and display windows (actually called surfaces.) SurfaceFlinger is implemented on top of OpenGL ES 1.x currently and can also use other hardware acceleration techniques when available (MDP, a 2D blitter on the T-Mobile … Read more
The Framebuffer object is not actually a buffer, but an aggregator object that contains one or more attachments, which by their turn, are the actual buffers. You can understand the Framebuffer as C structure where every member is a pointer to a buffer. Without any attachment, a Framebuffer object has very low footprint. Now each … Read more
