What to do if Dota says direct3d. Solving problems with DirectX initialization in games

Now that the render objects are set up, we can look at some additional functions, which will give us more control over our scenes in upcoming tutorials. First, we'll create a rasterization state that will give us control over how the polygons are rendered.

Set it to the overall size of the window. width = screen width; viewport. We will need to save a copy of this matrix so that we can pass it to our shaders used to render our scenes. This matrix will also be used to rotate, translate, and resize our objects in 3D space.

We will need to pass this copy to the shaders and also for rendering. Typically, this is where you create a view matrix that is used to calculate the position of the location from which you are viewing the scene. You can see this as the scene we're viewing through the camera. On this moment we'll skip this step. If you don't do this and you try to free the switch channel in full screen mode, exceptions will be thrown. All it does is initialize the buffers so they are empty and ready to draw.

They are often caused by frames. The next three functions provide copies of the projection, world, and orthographic matrices to the calling functions. Most shaders need these stamps to render, so exterior objects need an easy way to get a copy. We won't name these functions in this tutorial, just explain their presence in the code.

The latter functions return by reference the name of the video card and the amount of memory that was allocated. Knowing this information can help you debug various configurations. There are some benefits to using this, but you still need to know how to activate it.

Typically, faster loading and increased fluidity are found. And as some will benefit from 30fps with an old graphics card, it's worth a try! Not many games use it, but the specs were completed less than six months ago! To launch it, don't forget to go to the game's advanced settings to check that the console launch is assigned to the key! Please note that you need updated drivers for your video card, otherwise it won't work!

If there is a problem, you can describe it. There's no guarantee that the phones will cost that much in Bulgaria, or even that's their actual price, but at least we have an idea of ​​what to expect. These are free sale prices and will certainly be lower when linked to a contract.

The model doesn't have the best features, but there are plenty of apps and games aimed at smaller users. This is a resource manager. This is his main, overarching goal. Here, however, we come to a slight paradox. Such requirements can only be reasonably implemented when we logically extract the part from the code that will be responsible for resource management. However, if none of the above situations apply to us, there is no reason to start building a resource management module just because "the resources have to be somewhere."

Something like " simple manager resources" is an oxymoron: if it can actually be simple, it probably means it isn't necessary. Resizing an enum type can be difficult in certain situations. Why do you need such a hack?

There is nothing unusual about taking screenshots. Just press the "Print Screen" key and the image on the screen will appear on the system clipboard, after which we can use it in any way. At least that's what we usually expect. In fact, taking screenshots is a rather slippery topic if we are dealing with anything more than the usual window applications. They use a mechanism known as hardware overlay, allowing - in short - to bypass the operating system overhead associated with managing multiple application windows on a shared monitor screen.

The side effect is, among other things, that the built-in screenshot mechanism becomes useless in this situation if you want to take a screenshot of this type of application. However, regular screenshots usually provide corresponding solutions in the games themselves. One way is if a keypress is detected for screenshots, render the scene first to the texture and then to the screen. The texture can then be saved to a file.

Fusion at its finest. Well, no, for three reasons. Relatively least important is that the implementation can be cumbersome since it requires the start and end of the rendering pipeline in the application to be coordinated with the next render target. The absence of multisampling in the resulting picture is more important. It won't look very good, not to mention it won't match what you see on the screen.

So how do you take screenshots? Exactly what intuition tells us: you should take what you see on the screen, that is, the contents of the front buffer and save it to a file. It is important to remember the correct surface dimensions, such as the front buffer. In full screen mode this corresponds to a back buffer, but when resizing the window it should not be a windowed application.

For this we still have the necessary documentation and example applications showing the use of individual elements or presenting implementations of various graphical effects. But that's not all you can find in this several hundred megabyte package. The support tools found there are almost as important.

Some of these tools are so useful that it's worth putting shortcuts to them in places that are easily accessible. When programmers are bored, they often argue about terminology. The subject of such disputes is usually vague words, which are sometimes - usually erroneously - used as evaluation attributes.

Practical difference between the following calls. In both cases it is a matter of taste, and we should not assume that traits that are positive for us will be equally well received by others. The Internet is full of descriptions teaching aids and code examples showing how to implement various graphical effects. A much bigger problem is combining multiple effects so that they are applied simultaneously to the same scene. Because each individual effect may require code in many different places on the graphics stream, integrating all of these pieces doesn't seem straightforward.
