10 quick ways to clear space on an overstuffed Android device


The output of a vertex shader along with texture maps goes to an interpolation stage and then to the pixel shader. The pixel shader is another programmable function that allows flexibility in shading an individual pixel.

What is simple shader?

A programmable function in graphics cards that offers a programmer flexibility in rendering an image. The vertex shader is used to transform the attributes of vertices (points of a triangle) such as color, texture, position and direction from the original color space to the display space.

A material is what you apply to geometry to give it a colour and pattern. Michael Simon/IDGThe best way to free up space on your Android phone is to add more of it.

What is a Shader?

They take as input a whole primitive, possibly with adjacency information. For example, when operating on triangles, the three vertices are the geometry shader's input. The shader can then emit zero or more primitives, which are rasterized and their fragments ultimately passed to a pixel shader. The CPU sends instructions (compiled shading language programs) and geometry data to the graphics processing unit, located on the graphics card. GLSL shaders themselves are simply a set of strings that are passed to the hardware vendor's driver for compilation from within an application using the OpenGL API's entry points.

Currently the only type of 2D shader is a pixel shader. OpenGL 2.0 incorporates the significant addition of the OpenGL Shading Language (also called GLSL), a C like language with which the transformation and fragment shading stages of the pipeline can be programmed. GLSL shaders are not stand-alone applications; they require an application that utilizes the OpenGL API, which is available on many different platforms (e.g., GNU/Linux, macOS, Windows). There are language bindings for C, C++, C#, JavaScript, Delphi, Java and many more.

What is uniform matrix?

GTX is NVIDIA's top tier cards. Its a visual indication of power.

As a result a GPU will implement a large number of shader cores to work on multiple pixels in parallel. The use of a “wide” design is well suited for graphics rendering as it allows each shader core to be clocked relatively low, saving power while achieving work in bulk. Introduced in 2001, vertex shaders and pixel shaders are supported by OpenGL and DirectX. A programmable function in graphics cards that offers a programmer flexibility in rendering an image. The vertex shader is used to transform the attributes of vertices (points of a triangle) such as color, texture, position and direction from the original color space to the display space.

The official OpenGL and OpenGL ES shading language is OpenGL Shading Language, also known as GLSL, and the official Direct3D shading language is High Level Shader Language, also known as HLSL. Cg, a third-party shading language which outputs both OpenGL and Direct3D shaders, was developed by Nvidia; however since 2012 it has been deprecated. Apple released its own shading language called Metal Shading Language as part of the Metal framework.

This post is to solve the puzzles so that you'll know what to delete if you press Clear Cache and Clear Data buttons. Finally, there will be guide on how to clear app cache and data on Android.

The OpenGL ARB created the OpenGL Shading Language to provide a more intuitive method for programming the graphics processing unit while maintaining the open standards advantage that has driven OpenGL throughout its history. From what I understand so far, the OpenGL user first has to prepare all the geometry to be used and configure the OpenGL server (number of lights allowed, texture storage, etc). Once that's done, the user then has to provide at least one vertex shader program, and one fragment shader program before an OpenGL program compiles. Game developers push the envelope for fast graphics rendering and determine the right balance of vertex shading and pixel shading. Sometimes, the pixel shader, which is also called a "fragment shader," performs no processing and acts only as a pass-through.

Adding another scanned photo of the bumps and contours of the same brick wall to the Bump Mapping attribute is also considered applying a texture. Nevertheless, because textures are often applied to shaders, the entire process of shading is sometimes informally referred to as texturing.

This is what's called a Pixel Shader(sometimes referred to as aFragment Shader). This lets you start programming shaders right in your browser, without the hassle of setting anything up!

Cached data is temporary data that an app stores in phone memory for later reference so that it can load things faster. For example, when you first load Instagram, Instagram will save profile pictures, images, posts that you've read in the cache of phone memory. Next time the app needs the data, it can refer to phone memory with no need to download the data again, and the app thus loads faster.

Unlike many of life’s little annoyances, though, this one’s easy to fix. You can quickly clear out hundreds of megabytes or even a gig or two by sweeping up stale downloads, rooting out offline maps and documents, clearing caches, and wiping unneeded music and video files. And if these tips don’t do the trick, check out our picks for the best Android phonesfor every need and budget. This will delete the cached data of all apps on your Android phone. Besides app cache, there is system cache, which retains temporary system data for Android system to load things faster.

  • A typical real-world example of the benefits of geometry shaders would be automatic mesh complexity modification.
  • The choice between VS/FS for raytracing on gpu is made when you consider what's the actual output of a certain shader stage.

If something is not a built in variable, you can send that information from the CPU (your main program) to the GPU (your shader). You can see all the variables being passed to the shader in the Shader Inputs tab. Variables passed in this way from CPU to GPU are called uniform in GLSL. The proportion of the screen that is red will differ depending on the size of the screen. To ensure that exactly half of the screen is red, we need to know how big our screen is.

What is an SHADER file?

Summing things up then, we have ALUs, the most basic building block in a GPU shader design. From those ALUs we build up a shader core, and then we group those shader cores into a array of (typically) 16 or 32 shader cores. Finally, those arrays are fed threads of instructions, one thread per shader core, which like the shader cores are grouped together. Not unlike the construction of a shader core, how shader cores are grouped together will depend on the design. The most common groupings are either 16 or 32 shader cores.

A Note on Debugging Shaders

What are materials in unity?

Materials: Materials define how a surface is to be rendered. This is achieved by selecting a shader for the material and then setting the public properties of the underlying shader. Physically Based Rendering (PBR): PBR is a technique which mimics the interaction of light with different materials in a realistic way.

Sharder description

It was created by the OpenGL ARB (OpenGL Architecture Review Board) to give developers more direct control of the graphics pipeline without having to use ARB assembly language or hardware-specific languages. Ben PattersonThe “cached” data used by your combined Android apps can easily take up more than a gigabyte of storage space. That's all you need to know about clearing app cache and data on Android phone. To be clear, clearing app cache and data does help to fix misbehaved apps or system problem but it is not a effective solution to freeing up space on Android phone. The phone will recreate the new cache and data after the cache and data is deleted.

Is GPU only for gaming?

In a smartphone, the GPU (graphics processing unit) is a central part of the system hardware. It differs from the CPU by handling the visual rendering elements of a phone's display, whereas the CPU is the brain of the device, handling all the heavy computation and logic behind the screen.

OpenGL 1.2.1 (

ALUs are the most fundamental building blocks in a GPU, and are the base unit that actually performs the mathematical operations called for as part of a shader program. The bulk of the information Imagination is sharing with us today is with respect to shaders, so that’s what we’ll focus on today.

Shaders can be created on the fly from within an application, or read-in as text files, but must be sent to the driver in the form of a string. ShaderToy displays simple GLSL that is programmed to handle all the lighting, geometry, etc, it's not vertex geometry, it's raycasting most of it, the 3D stuff, or you can do 2D shaders, etc. Generally, raytracing is done on CPU, and rays are traced through a pixel, for each pixel in the image. Since pixel shader is a program that is run for each pixel in the rasterized primitive, than it's more natural and intuitive do use fragment shader for raytracing, than vertex shader. However, there're things like vertexshaderart.com also.

What is GLSL file?

Shaders use GLSL (OpenGL Shading Language), a special OpenGL Shading Language with syntax similar to C. GLSL is executed directly by the graphics pipeline. There are two types of shaders: Vertex Shaders and Fragment (Pixel) Shaders. Vertex Shaders transform shape positions into 3D drawing coordinates.
