    Over the past week, some of our readers have come across a known error message with the directx 10 Free Look Camera. This problem can occur for many reasons. Let’s discuss this below.

    Okay, so I promised to write a tutorial on how to write a simple and free vector camera. This guide applies not only to DirectX10, but to almost all graphics APIs. We want to keep things simple, so the simplest camera we can implement other than a human camera is a free-view camera (no roles), so there are usually only two degrees of freedom: left/right, not to mention up /down, we are also trying to implement pauses in forward/backward movement and fine left/right.

    Camera Basics

    Functions first, as usual, I won’t go into the details of rendering and projections, and http://en.wikipedia.org/wiki/3D_projection. Okay, now consider that each 3D scene must have a virtual camera with a field of view (FOV-theta) and near (a) and far (b) view planes, which together form the view cone shown in Figure 1. This truncated cone defines what is seen in the interior of the scene, all geometric cuts and views. Surface suppression is based on their trunk.

    Now the shape of the barrel is determined by the tool you are using Section. There are several types of projections, but chances are that you will end up using a perspective projection. Now the projection screen is attached to our virtual lens (think of a projection as a good one-piece camera lens), in order to navigate the scene, we need to know the position from which we are viewing the scene, the direction in which we are. entrance If you are looking up and which process is at the top (see Consideration 2), it is now the direction up is relatively important for motion calculations and of course for displaying the scene with the upward force upwards 😉 These three landmarks are called the eye position, I I would say the view vector and the inclusion vector.

    For a free-view camera, the up vector must be inside the top direction of the camera. If we were to make a camera for people for beginners, where the viewer is always glued to the ground, their direction will always be upwards. from Paradise. So if you can see the scene, you need to position the virtual camera somewhere in each scene (position/up/view) and plug it in.Move it to some kind of lens (projection).

  • Now I need to quickly explain what happens to the vertices of the new good object as it moves through the render pipeline. If an object’s vertex maintains a downward rendering direction, it has a position in nation model space, that position is now moved to where the object should definitely be in the world, by multiplying the vertex by the point’s -world matrix. Now, if you are traveling around the world, you imagine that the world stops while the camera is moving, but from now on, it is useful to think of the opposite, since the camera is stationary and the country is a moving world. Because it was so in the past.

    The video camera never moves, the position of the world is actually adjusted to convey this perception. Once positioned so that our object is in the world, the next step is to move the product to match our sitting and viewing point. If we want to search to the left of the room, we need to move the whole world to the right so that people multiply the vertex position by their own view matrix to moveXia as needed. Remember that although each individual object has its own range matrix, they all use the same representation matrix. The previous step that needs to be given to each vertex is the lattice matrix. In a real camera, a particular lens affects the displayed image, and can also optionally apply distortion to the entire scene (for example, a fisheye lens), the entire projection of the virtual lens (matrix), exactly how it works, vertices are converted to clips and gaps. according to this view cone that we have defined. Once our vertices are fully transformed, these types of people are then sent to a random pipeline rasterization stage, where the person is assembled into primitives and eventually converted to a 2D image.

    Figure 4 shows the whole class structure for our camera, below is the tool code, we have two matrices: view and projection, we both work, we need to position the stanza da letto, change the view and so on. .
