First of all, according to the following figure, roughly explain the currently popular AGP (Accelerated Graphics Port, graphics acceleration port) graphics rendering process.
Each rendering process includes the execution of two main functional modules: Vertex Processing and Pixel Processing.
First, the graphics card receives vertex data from the AGP bus. These data include position, normal, texture coordinates (if bread is more likely to need textures, ie map coordinates are not required), etc. These are all without any transformation, ie, in the object's local space (Object Space) The original coordinates. Each vertex is sent to the vertex processing unit in turn, where the coordinates are transformed, lighting calculations (if per vertex lighting) and other work, the result of the transformation is directly available for each triangular transformation screen space.
The transformation matrices, lights, and other information used here are one-time passes to the graphics card for each batch of vertices, as the video card resources. The vertex processing delimits the range of the triangle. The next step is to fill the triangle pixel by pixel. Which pixels are filled is determined by the linear interpolation of the vertex screen coordinates. Other necessary parameters of the pixel, such as color, texture coordinates, etc. are also obtained by interpolating these attributes of the vertices calculated in the previous step.
In addition, each pixel is also determined by depth detection and template detection. The pixels to be drawn are sent to the pixel processing module for mapping pixel values, texture blending, etc. If necessary, per-pixel lighting is also done here. Here the map and other information is also used as a video card resources. The final processing result of the pixel is put into the frame buffer.
Resolver is a kind of commonly used angle detection component, because of its simple structure, reliable operation, and its accuracy can meet the general detection requirements
