This paper is based on the calculation and visualization of Gaussian curvature of triangular grid surface in the same mountain.Long time no code to write, recently computed triangular mesh surface Gaussian curvature practiced hand, and realized the Gaussian curvature visualization, review a little bit of differential geometry knowledge. Sometimes it is necessary to write the code yourself, debug run, combin

1Surface Acoustic Waves Surface acoustic waves, a type of ultrasonic waves, in the media ( Rigid materials such as glass or metal ) Mechanical energy waves transmitted from the superficial layer. Through the wedge-shaped triangular pedestal (strictly designed according to the wavelength of the Surface Wave), it can realize oriented and small-angle surface a

Microsoft's recruitment philosophy-Five Core qualities of being a Microsoft employee (from Microsoft's 360 degree) Microsoft has been committed to discovering and attracting elites in the industry. In the early days of its establishment, Bill Gates and Steve Ballmer personally participated in the recruitment of all new employees. Their philosophy of employing people and recruitment philosophy were as foll

Preface When we use canvas, we usually directly set its width and height in the canvas element: Of course, you can also set it in the CSS style without setting it in the canvas, because the canvas itself is also an HTML node. canvas{width:600px;height:300px} After setting, open the page and find that the canvas size is OK. At this time, we will draw a 40*40 rectangle on it to see the effect. var canvas = document.getElementById(‘canvas‘), context = canvas.getContext(‘2d‘); context.fillStyl

Surface shaders must be affected by lights and shadows. Surface shaders is a shader that is easier to write light-it is an abstract encapsulation with unity. The standard output structure of the surface coloring tool is as follows: struct surfaceoutput {fixed3 albedo; // diffuse color fixed3 normal; // tangent space normal, if written fixed3 emission; half specul

Some time ago, the giant hard released a new input device surface Dial, with surface studio used to be simply cool to no friends. I was fortunate to be involved in the company's business training, the biggest harvest is to discover that WPF can also develop dial, WPF can actually use the UWP api! Not suspense, the key is a nuget named "Uwpdesktop", which adds this nuget to our WPF program. The WPF tuning U

The continuous smooth deformation of the mathematical surface can be modeled by minimizing the energy function, in which the energy function is used to adjust the degree of stretching or bending of the surface, so the optimal solution of minimizing the energy function and satisfying all boundary conditions is to find the surface.The energy function is usually the form of a two-time function:Where s* represe

Surfaceflinger object creation process 1 surfacesession Creation When a client requests to create a surface, it first establishes a session with surfaceflinger, and then creates a connection on the session to return the bclient object through the concept. Windowmanagerservice checks whether a surfacesession is established before adding the first window. If no surfacesession is established, a new instance is created to represent a connection with surf

The curved surface generated when the hyperbolic curve rotates around its symmetric axis is a bilinear surface. In mathematics, Hyperbolic SurfaceIs a quadratic surface. The single-leaf dual-surface can be expressed in the formula (x ^ 2)/(a ^ 2) + (y ^ 2)/(B ^ 2)-(Z ^ 2) /(C ^ 2) = 1 In reality, the structure of cooli

color. We neither look at them nor need to draw precious ink on them (GPU parallel processing capability)So we can change the longitude green false colored sphere in the example, erase its longitude >0.5 part, then the code should change to:So give this shader to material, and then give a sphere to see the green fake color ball we saw last time just left the southern hemisphere:Looks like solid from the front.A little tilt. I can see from above that the inside of the sphere is hollow, so I use

Where is the future of Net technology?-On the Microsoft technical line and. net technical line Winform: The advantage is that it is easy to learn, but the disadvantage is that the interface is not easy to understand and the interface adaptability is poor.

Spiral surface of mathematical graphicsThis section describes how to generate spiral surfaces. for related software, see: Mathematical graphics visualization tool. Use script code with custom syntax to generate mathematical graphics. I have previously written a C ++ program for generating a ring. The code is published on the Generation Algorithm of the Spire graph (1) the positive spiral surface is to make

Spanish architect Antoni Gaudí said: The straight line belongs to the human, the curve belongs to God.Well. There seems to be some truth to it. Sydney Opera House, Bird's Nest, Guangzhou "small waist", these landmarks seem to have really a lot of curves. Of course, the use of straight lines of well-known buildings are also a few, but always seem to lack some "smart", more "clumsy".650) this.width=650; "Src=" https://mmbiz.qlogo.cn/mmbiz/ Ruqiapclr2r16qdife6ydan9kv1znpg2llwf8dccpnnhbkg1qmxfec5mht

【Writing surface shaders] Writing shaders that interact with lighting is complex. There are different light types, different shadow options, different rendering paths (forward and deferred rendering), and the shader shocould somehow handle all that complexity. Surface shaders in unity isCode Generation ApproachThat makes it much easier to write your shaders than using low level vertex/pixel shader programs.

fact, only a few rays from a light source pass through the reflection and transmission (refraction) of the scene to the eyes of the observer. Therefore, the standard light tracing algorithm uses reverse tracking technology to draw the entire scenario. Light tracing: Starting from the viewpoint, each pixel center on the image plane emits a line of light to the scene. The light starts from the viewpoint, and the direction is the pixel center and the unit vector of the viewpoint line. There are th

The main principle is: the use of different surface roughness (roughness) different, resulting in ultrasonic wave of different reflection. According to Endura theory, the wave amplitude of smooth surface reflection is large and the duration is short. As the roughness increases, the amplitude decreases and lasts longer. Analyzing waveform data, you can extract many features (feature): Window length, peak, pe
