Usually textures contain image data, but it is data, you can do with it whatever you want. In GLSL a texture is specified as a uniform
Maximizing Depth Buffer Range and Precision
(new: Japanese translation available, thanks to Yuki Ozawa) Common depth buffer setups used in 3D graphics hardware to this day are woefully inadequate for the task. One can easily get artifacts known as z-fighting even with relatively limited scene depth range. Utilization of the available depth buffer values is quite horrible: half of the resolution is essentially wasted just in the distance fro

Vertex Specification - OpenGL Wiki
Vertex Specification is the process of setting up the necessary objects for rendering with a particular shader program, as well as the process of using those objects to render. Theory[edit] Submitting vertex data for rendering requires creating a stream of vertices, and then telling OpenGL how to interpret that stream. Vertex Stream[edit] In order to render at all, you must be using a shader progr
ANativeWindow – charleszblog
In this post, we discuss BufferQueue, BufferQueue::BufferSlot and BufferQueue::BufferState defined in frameworks/native/include/gui/BufferQueue.h. BufferQueue We have learned the concepts of ANativeWindow and ANativeWindowBuffer defined in system/core/include/system/window.h with class Surface (in frameworks/native/include/gui/Surface.h) being concrete implementation of the former class and Graphi
Load OpenGL Functions - OpenGL Wiki
Loading OpenGL Functions is an important task for initializing OpenGL after creating an OpenGL context. You are strongly advised to use an OpenGL Loading Library instead of a manual process. However, if you want to know how it works manually, read on. Platform Specific Function Retrieval[edit] Querying the function pointers requires using a function not defined by the OpenGL API. It is a platform-
