Now when all major matrixes are set, we call the Draw method of the model which renders the model to the screen. Now, just to make the picture look nicer, we will change our matrixes a little. We position our model lower by multiplying the World matrix by the translation matrix. We will also move the camera a little closer to the model's position.
As you can see, our model is not lighted and because of that, it doesn't look very nice. We will solve this problem later; now let's talk about what happens when we call the Draw method. If you are familiar with any older version of the XNA Framework, you may be surprised by the fact that there is no code that goes through all the model meshes and sets the effect parameters.
The matter is that all this code is hidden now in the Draw method of the model. On the other hand, if you use this new Draw method, you lose the possibility to adjust effect parameters. To have this possibility again, we will apply an old method of rendering using a basic effect this effect is actually called BasicEffect. This is how it looks:. This code will take effect only if BasicEffect is set as the default effect in the properties of the Content Processor.
Before going further, we need to understand the code which we just created because we will need it later. Each model consists of meshes which are positioned in the local coordinate system of the model. So before rendering each mesh, we need to transform its coordinate system to world space. The model also contains Bones which are the transformation matrixes for the meshes.
Then go through each mesh and render it with the given effect which is usually set in the properties of the Content Processor. We also need to set all the needed parameters for those effects.
The major parameters are World, View, and Projection matrix. When setting the World matrix for the model effect, make sure you use the transformation matrix from the Bones array.
XNA Framework for Windows and Xbox fully supports custom shader effects, but for Windows Phone 7, only five built-in effects are supported now. In this part of the article, we will go though each of these effects. We already saw BasicEffect at work in the last example, now we are going to look at this effect in detail because this effect is used most often. BasicEffect implements Blinn-Phong light model with up to three directional lights both per-vertex and per-pixel.
It supports models with or without textures. We will have one red light source to left, one blue to the right, and a green light source just in front of our model. Actually, we need to set the direction not position of the light, but here I use position just to make things a little more clear.
This is how we can do it in code, just set the DirectionalLight0 , DirectionalLight1 , and DirectionalLight2 parameters:. Another cool thing with BasicEffect is the Fog effect. This might be used, for example, in scenes in an open space where objects which are far enough from the camera should be a little shaded. FogEnabled enables or disables fog, and FogColor is just the color of the fog. The meaning of FogStart and FogEnd parameters might be better understood by looking at the following picture:.
To see the fog effect in a scene with multiple models, first we will extract a method which will render a single teapot. We also set the parameters of the fog there. In the following picture, you can see that the fog intensity grows with the distance from the camera:.
DualTextureEffect is a simple multi-texturing effect. It allows you to apply two textures to the model. It also supports fog like BasicEffect.
DualTextureEffect is a good effect because of its "cheapness" for hardware compared to other effects , and it might be used for applying light maps, masks, decals, tiling, and so on.

The malicious software can intentionally corrupt DLL files in order to substitute them with its own malicious files. Therefore, your number one priority should be to scan your computer for malware and eliminate it as soon as possible. The new version of Windows 10 has a built-in application called "Windows Defender" , which allows you to check your computer for viruses and remove malware, which is difficult to remove in a running operating system.
Outbyte products are one of the most popular and effective to fight malware and unwanted programs, and they will come in handy even when you have a high-quality third-party antivirus installed. Scanning in the new version of Malwarebytes can be performed in real time and manually. To initiate manual scan please follow the steps below:.

XNA Build is a set of game asset pipeline management tools, which help by defining, maintaining, debugging, and optimizing the game asset pipeline of individual game development efforts.
A game asset pipeline describes the process by which game content, such as textures and 3D models, are modified to a form suitable for use by the gaming engine.
XNA Build helps identify the pipeline dependencies, and also provides API access to enable further processing of the dependency data. The dependency data can be analyzed to help reduce the size of a game by finding content that is not actually used. XNA Game Studio is a programming environment for development of games.
Five revisions have been released so far, but as of , no new versions will be developed. XNA Game Studio Express was the first version released on August 30, , and was intended for students, hobbyists, and independent game developers. It was available as a free download. Express provides basic "starter kits" for rapid development of specific genres of games, such as platform games, real-time strategy, and first-person shooters.
XNA Game Studio 2. XNA Game Studio 3. It was released on October 30, , and supported C 3. XNA Game Studio 4. It added support for the Windows Phone platform including 3D hardware acceleration , framework hardware profiles, configurable effects, built-in state objects, graphics device scalars and orientation, cross-platform and multi-touch input, microphone input and buffered audio playback, and Visual Studio integration.
