Shader Model 3.0
I have downloaded a game that requires 3.0 shader model video card but my pc have 0.0 shader model videocard; game requires shader model 3.0 what can i do to obtain that. I am trying to play a game called Lego Marvel Superheroes. When i open the game it says that my video card doesn't support Shader Model 3.0. Here are the minimum.
Shaders can also be used for special effects. An example of a from a unshaded on the left, and the same image with a special effects shader applied on the right which replaces all light areas of the image with white and the dark areas with a brightly colored texture. In, a shader is a type of that was originally used for (the production of appropriate levels of, and within an image) but which now performs a variety of specialized functions in various fields of computer graphics or does unrelated to shading, or even functions unrelated to graphics at all. Shaders calculate effects on graphics hardware with a high degree of flexibility.
Most shaders are coded for a (GPU), though this is not a strict requirement. Shading languages are usually used to program the programmable GPU, which has mostly superseded the that allowed only common geometry transformation and pixel-shading functions; with shaders, customized effects can be used. The position, hue, saturation, brightness, and contrast of all, or used to construct a final image can be altered on the fly, using defined in the shader, and can be modified by external or textures introduced by the program calling the shader.
Shaders are used widely in postprocessing, and to produce a seemingly infinite range of effects. Beyond just simple lighting models, more complex uses include altering the, or of an image, producing, for depth effects, (so-called '/' effects), and, effects, and a wide range of others. Contents. History The modern use of 'shader' was introduced to the public by with their ' Specification, Version 3.0' originally published in May 1988. As evolved, major graphics software libraries such as and began to support shaders. The first shader-capable GPUs only supported pixel shading, but vertex shaders were quickly introduced once developers realized the power of shaders.
The first video card with programmable pixel shader was the Nvidia GeForce 3 (NV20), released in 2000. Geometry shaders were introduced with Direct3D 10 and OpenGL 3.2. Eventually graphics hardware evolved toward a. Design Shaders are simple programs that describe the traits of either a or a. Vertex shaders describe the traits (position, colors, etc.) of a vertex, while pixel shaders describe the traits (color, and value) of a pixel. A vertex shader is called for each vertex in a (possibly after ); thus one vertex in, one (updated) vertex out. Each vertex is then rendered as a series of pixels onto a surface (block of memory) that will eventually be sent to the screen.
Shaders replace a section of the graphics hardware typically called the Fixed Function Pipeline (FFP), so-called because it performs lighting and texture mapping in a hard-coded manner. Shaders provide a programmable alternative to this hard-coded approach. The basic is as follows:. The CPU sends instructions (compiled programs) and geometry data to the graphics processing unit, located on the graphics card. Within the vertex shader, the geometry is transformed.
If a geometry shader is in the graphic processing unit and active, some changes of the geometries in the scene are performed. If a tessellation shader is in the graphic processing unit and active, the geometries in the scene can be.
The calculated geometry is triangulated (subdivided into triangles). Triangles are broken down into fragment quads (one fragment quad is a 2 × 2 fragment primitive). Fragment quads are modified according to the fragment shader. The depth test is performed, fragments that pass will get written to the screen and might get blended into the. The graphic pipeline uses these steps in order to transform three-dimensional (or two-dimensional) data into useful two-dimensional data for displaying.

In general, this is a large pixel matrix or '. Types There are three types of shaders in common use, with one more recently added.
This Game Requires At Least Shader Model 3.0
While older graphics cards utilize separate processing units for each shader type, newer cards feature which are capable of executing any type of shader. This allows graphics cards to make more efficient use of processing power.
2D Shaders 2D shaders act on, also called in computer graphics work. They modify attributes of. 2D shaders may take part in rendering 3D geometry. Currently the only 2D shader types are pixel shaders. Pixel shaders Pixel shaders, also known as shaders, compute and other attributes of each 'fragment' - a technical term usually meaning a single.
The simplest kinds of pixel shaders output one screen as a color value; more complex shaders with multiple inputs/outputs are also possible. Pixel shaders range from always outputting the same color, to applying a lighting value, to doing, translucency and other phenomena.
They can alter the depth of the fragment (for ), or output more than one color if multiple render targets are active. In 3D graphics, a pixel shader alone cannot produce very complex effects, because it operates only on a single fragment, without knowledge of a scene's geometry. However, pixel shaders do have knowledge of the screen coordinate being drawn, and can sample the screen and nearby pixels if the contents of the entire screen are passed as a texture to the shader.
This technique can enable a wide variety of two-dimensional postprocessing effects, such as blur, or /enhancement for cartoon/cel shaders. Pixel shaders may also be applied in intermediate stages to any two-dimensional images— or —in the pipeline, whereas vertex shaders always require a 3D scene. For instance, a pixel shader is the only kind of shader that can act as a or for a video stream after it has been.
3D Shaders 3D shaders act on or other geometry but may also access the colors and textures used to draw the model or mesh. Vertex shaders are the oldest type of 3D shader, generally modifying on a per-vertex basis. Geometry shaders can generate new vertices from within the shader. Tessellation shaders are newer 3D shaders that act on batches of vertices all at once to add detail—such as subdividing a model into smaller groups of triangles or other primitives at runtime, to improve things like and, or change other attributes. Vertex shaders Vertex shaders are the most established and common kind of 3D shader and are run once for each given to the graphics processor.
The purpose is to transform each vertex's 3D position in virtual space to the 2D coordinate at which it appears on the screen (as well as a depth value for the Z-buffer). Vertex shaders can manipulate properties such as position, color and texture coordinates, but cannot create new vertices.
The output of the vertex shader goes to the next stage in the pipeline, which is either a geometry shader if present, or the. Vertex shaders can enable powerful control over the details of position, movement, lighting, and color in any scene involving. Geometry shaders Geometry shaders are a relatively new type of shader, introduced in Direct3D 10 and OpenGL 3.2; formerly available in OpenGL 2.0+ with the use of extensions. This type of shader can generate new graphics, such as points, lines, and triangles, from those primitives that were sent to the beginning of the. Geometry shader programs are executed after vertex shaders.
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. Typical uses of a geometry shader include point sprite generation, geometry, extrusion, and single pass rendering to a. A typical real-world example of the benefits of geometry shaders would be automatic mesh complexity modification. A series of line strips representing control points for a curve are passed to the geometry shader and depending on the complexity required the shader can automatically generate extra lines each of which provides a better approximation of a curve. Tessellation shaders As of OpenGL 4.0 and Direct3D 11, a new shader class called a tessellation shader has been added.

It adds two new shader stages to the traditional model: tessellation control shaders (also known as hull shaders) and tessellation evaluation shaders (also known as Domain Shaders), which together allow for simpler meshes to be subdivided into finer meshes at run-time according to a mathematical function. The function can be related to a variety of variables, most notably the distance from the viewing camera to allow active level-of-detail scaling. This allows objects close to the camera to have fine detail, while further away ones can have more coarse meshes, yet seem comparable in quality. It also can drastically reduce required mesh bandwidth by allowing meshes to be refined once inside the shader units instead of downsampling very complex ones from memory. Some algorithms can upsample any arbitrary mesh, while others allow for 'hinting' in meshes to dictate the most characteristic vertices and edges. Primitive shaders AMD Vega microarchitecture added support for a new shader stage—. Other Compute shaders are not limited to graphics applications, but use the same execution resources for.
They may be used in graphics pipelines e.g. For additional stages in animation or lighting algorithms, (e.g. Some rendering APIs allow compute shaders to easily share data resources with the graphics pipeline. Parallel processing Shaders are written to apply transformations to a large set of elements at a time, for example, to each pixel in an area of the screen, or for every vertex of a model. This is well suited to, and most modern GPUs have multiple shader to facilitate this, vastly improving computation throughput.
A programming model with shaders is similar to a for rendering, taking the shaders as arguments, and providing a specific between intermediate results, enabling both (across pixels, vertices etc.) and (between stages). Programming The language in which shaders are programmed depends on the target environment. The official OpenGL and shading language is, also known as GLSL, and the official Direct3D shading language is, also known as HLSL. However, is a deprecated third-party shading language developed by that outputs both OpenGL and Direct3D shaders. Apple released its own shading language called as part of the. See also.

Microsoft DirectX, also simply known as DirectX is a set of used in the development and programming of video games on Microsoft operating systems (Windows and Xbox). Introduced in 1995, shortly after the release of Windows 95, it has since been bundled in every version of Windows since Windows 98.
With the release of DirectX 12 in 2015 Microsoft introduced a number of new programming features such as low level APIs that allow developers more control over what commands are sent to the graphics processing unit. The DirectX 12 APIs will also be utilized in and game development in addition to. Since the release of DirectX 8.0 graphics cards have used programs/instructions known as Shader Models to help interpret instructions on how to render graphics sent from the CPU to the graphic card. Many are increasingly listing Shader Model versions in their system requirements. However these shader versions are tied to the version of DirectX that you have installed on your PC which is then in turn tied to your graphics card. This can make it difficult to determine if your system can handle a certain shader model or not.
How To Determine the DirectX Version You Have?. Click on the Start menu, then 'Run'. In the 'Run' box type 'dxdiag' (without the quotes) and click 'Ok'. This will open up the DirectX Diagnostic Tool.
In the System tab, listed under the 'System Information' heading you should see a 'DirectX Version' listed. What Games Support DirectX 12? Most PC games developed prior to the release of DirectX 12 were most likely developed using and earlier version of DirectX. These games will be compatible on PCs with DirectX 12 installed due to the backwards compatibility.
If by chance your game is not compatible under a new version of DirectX, mainly games running on DirectX 9 or earlier, Microsoft provides DirectX End-User Runtime that will fix many run time errors with installed from the older versions of DirectX. How to Install the Latest Version of DirectX? Installation of the latest version of DirectX is only necessary when you're trying to play a game that has been developed with that latest version. Microsoft has made it very easy to stay up to date and it can be updated via the standard Windows Update and through manual download and installation. Since the release of DirectX 11.2 for Windows 8.1, however, DirectX 11.2 is no longer available as a standalone download/installation and must be downloaded through Windows Update. In addition to Windows Update, most games will check your system on installation to see if you meet the DirectX requirements, if you don't you will be prompted to download and install prior to installing the game.
