performance gains of Al Most 4x.WebService Remoting WCF simple Speed comparisonA Performance Comparison of Windows communication Foundation (WCF) with Existing distributed communication technologie SThis is the authoritative point of MSDN:When migrating distributed applications written with ASP. NET Web services and. NET Remoting To WCF, the performance are at least comparable to the other existing Microsoft distributed communication technologies. In most cases, the performance are significantl

InnoDB is set to the prefix index (n bytes before the string). The possible cause isCHAR(32)Only the first 16 bytes indexes are supported. PostgreSQL's Partial Indexes has benefited from many aspects and is even larger. Because Indexes on Expressions exists, you can also index suffix, or even the value obtained by the index through the string function, in addition to the prefix index of MySQL. For example, PostgreSQL can set "I only need to index the username of the person born in January 1 」

understood as each point that makes up an object.A vertex Shader is executed once for each vertex (vertex) that is sent to the GPU. The input data is: Attributes: Encapsulates data for each vertex using a vertex array, typically for variables with different vertices, such as vertex position, color, and so on.Output data: At least the location information should be output at the vertex shader stage-that is, the built-in variable: gl_position, which is the intrinsic varying of each point, represe

This requires a Glstencilop method.1 void glstencilop (glenum sfail, Glenum dpfail, Glenum dppass); Sfail: The action to take if the template test fails. Dpfail: The action to take if the template test passes, but the depth test fails. Dppass: If both the depth test and the template test are passed, the action will be taken. The Glstencilop function is set to

The use of fog in the scene not only improves realism, but also optimizes performance in specific situations. In particular, when the object is far enough away from the camera, the fog is strong enough to see only the fog and not see the object, it is not necessary to the object coloring detailed calculation, which can greatly improve rendering efficiency.There are many mathematical models of fogLinear Model:F=max (min (end-dist)/(End-start), 1.0), 0.0) F is the atomization factor, the val

If you want to change the document's parent document, you cannot just update or reindex the old document (the new parent document may be on a different shard), you need to delete the old document and then re-index it.Application of parent-child relationshipSeeing Parent-child relationships, it's easy to think of a variety of JOIN operations like SQL-such as querying a document and retrieving all of the parent or child documents.H

OpenGL ES is similarCode: 1) create three vertices PrivateIntbuffer triggerbuffer = intbuffer. Wrap (NewInt[] { 0, One,0, -One,-one,0, One,-one,0, }); 2) use triggerbuffer to draw the vertex Example: Gl. glvertexpointer (3, gl10.gl _ fixed, 0, triggerbuffer ); Must use a native order direct buffer error often occurs. Solution: (create a method) /** OpenGL is a very underlying drawing interface. Its buffer storage structure is co

)The attribute variable is generally used to represent some vertex data, such as vertex coordinates, normals, texture coordinates, vertex colors, and so on.In application, the function glbindattriblocation () is used to bind the position of each attribute variable, and then the functionGlvertexattribpointer () assigns a value to each attribute variable.Here is an example:uniform mat4 u_matviewprojection;attribute vec4 a_position;attribute vec2 a_texcoord0;varying vec2 V_texcoord; void Main (void

OpenGL ES 08-do not use the mix color of mr. Bucket 1 Please note: I am not very satisfied with the status when I write this tutorial, so please do not care if you have any questions. If something goes wrong, don't worry. I will continue to explain it in section 2nd. Who is mr. Bucket? That's my kitchen mixer! (In English, mixer and mixed colors are the same.) Of course we are not talking about my kitchen mixer or mixed 3D software. We are talking abo

Details about the Texturing texture of OpenGL ES 3.0 (2), opengltexturing Texture Filtering and Mipmapping Texture Filtering and multi-level Texture We have already introduced the 2D texture of a single 2D image. This article mainly describes multi-level textures. Texture coordinates are used to generate a 2D index. When the zoom-in and zoom-out values are set to GL_NEAREST, a single texture will be matched to the texture coordinate position, which is

its local coordinate system (T). At this time, the order of the Code is the same as that of the local coordinate system relative to the object. GL. glmatrixmode (gl_modelview); By using the object's local coordinate system, you can better understand graphics systems such as robots and the solar system. The glulookat sub-function of the glulookat package of Android OpenGL ES provides a more intuitive way to set the modelview transformation

Unexpectedly today, the original s60 3rd native support for OpenGL ES, And now it gives me more fun ~~ However, unfortunately, my E50 performance is not strong, and I still have an independent video card n93 tough test to reach 442 frames, while my E50 only has a poor 81 frames. Fortunately, the performance of the third edition is indeed stronger than the previous second edition. N70 can only run to 77 frames, and the screen resolution is only 176x208
