In OpenGL, support for vertex shaders and fragment shaders is required for proper rendering, and each frame in the vertex shader is processed once for each vertex of the object in the scene.If you use OpenGL yourself, you need to read the model data in C + + code, passing vertex coordinates, vertex colors, and UV coordinates to the vertex shader.So in a vertex shader, you can modify the vertex data.Build a test scenario and import the FBX model with the book.In Unity3d, the FBX or other model is

simple let's take a look at the CSS section.Part II:CSS3When we see this picture above, everyone is sure that the first impression is CSS3 Box-shadow, But if it is just this we can achieve it? Very clearly not to.Whether it is the curved surface or the edge,box-shadow oneself is impossible to achieve, we need to cooperate with CSS3 pseudo-class elements to achieve.Let's look at the code together! Surface S

PS has a surface blur function, this function can be preserved at the edge of the image of the flat area of the fuzzy filtering, this function can achieve a good effect of grinding skin, its algorithm is as follows:This algorithm is very simple, set the radius r, to get a side length (2r+1) of the Square window, then the pixel value of the center pixel of the window is X, of course, for the pixel RGB three components, it is necessary to calculate sepa

If you're looking to buy Microsoft's surface studio, you'll probably have to wait a while to get it. When the new machine was released, the pre-sale activity also started, and shipped in mid-December. However, due to the large number of orders, now all three surface studio integration of new orders all delayed to 2017 shipments. With the Intel core I5,1TB hybrid hard drive, the low version of the 8GB RAM/

Create a 3D scene, such as outdoor is the sky, the earth has a distant background. This can be easily achieved by Skybox. The use of 1,skybox Skybox is actually a cube, just a different skin on each surface of the interior. Then the camera in the cube inside, feel like an indoor environment affixed to the blue sky and white clouds, let people feel that is on the scene. 2, reflection on the

As with some of the WPF controls that we commonly use, the Scatterview control also supports data binding capabilities. This article shows you how to use Scatterview to bind a sample picture in a Win7 system, and each picture is presented in a separate Scatterviewitem form.First, create a new Surface application (WPF) project, add the Scatterview control to the grid, and name it Mainscatterview.In C # code, add all the pictures under the "Sample Pictu

problem. Just knowing the basic concept of threading is far from enough, you must know how to deal with the concurrency problems such as deadlock, race condition, memory conflict and line Cheng. With these tips, you can easily handle multithreading and concurrent interviews. It's normal for many Java programmers to go to the interview before the interview. Because collecting face questions and exercises took time, I collected 50 hot questions from many interviewers about Java multithreading and

In ArcGIS, it is often necessary to split known surface layers (elements) based on known line layers (elements ). After research, construct features in the topology menu can be used. The details are as follows: To use line layer a and surface layer B, use a to split the B layer. The procedure is as follows:1. Open the editor editing toolbar and click start editing to start editing.2. Call up the topology m
