§4 Parabolic
1. Elliptical Paraboloid
(1) Standard equation
(2) Basic elements
* Vertex O (0,0,0)
* Spindle Z-axis
* Main plane Oyz plane: X=0;ozx plane: y=0
(3) When a=b, the elliptical parabolic surface is rotated by the parabola of the OZX plane around the z axis.
(4) intersection of planar and elliptic parabolic surfaces
* The intersection of planar and elliptic parabolic surfaces parallel to the z-axis is a parabola
* The planar z=k () perpendic
Here are some examples of surface shader. The following examples focus on using built-in lighting models, and for examples of how to use custom lighting models, see surface Shader Lighting Examples.SimpleWe will start with a very simple shader, and gradually improve on this basis. The following shader will place the surface color "white". It uses the built-in Lam

Let's talk about the 2D implementation of the water surface effect (1) and the 2d implementation of the water surface.
0. Introduction
I have always wanted to write my own understanding about the 2D implementation of water surface effects. Unfortunately, I have been dragging on for various reasons. Fortunately, some things have come to an end recently, and I have
§1. Spherical surface

Sphere and radius
1° Standard equation:
x²+y²+z²=r²
2° parameter equation
(Φ is longitude, theta is latitude)
3° spherical coordinate equation R=r sphere: G (0,0,0)
Radius: R
1° (x-a) ²+ (y-b) ²+ z-c (²=r²)
2° parameter equation:

The surface in protoolkit is expressed by prosurface. In the help document of protoolkit, it indicates that there are three types of surface in prosurface:
Prosurface -- surface, datum surface, or datum plane
But what are the differences between these three aspects:

Surface manager is a module responsible for displaying information in libraries under the framework in a user space. When the system executes multiple applications at the same time, surfacemanager is responsible for managing interaction between display and access operations, it is also responsible for the synthesis of 2D and 3D graphics.

Method 1: The simplest method, hold down the Windows button (Power key), and then press the volume reduction key. The screen darkens for a second, and the screenshot is saved in the Screenshots screenshot folder of the photo gallery.
Method 2: using the Surface 3 keyboard cover, first hold down the win key (the key on the keyboard with the Microsoft logo, not the power button on the tablet), and press the PRTSCN screen key. Effect and Method 1 the
can use Surface Book i7 like a tablet.
So although the two input methods are very different, but obviously Microsoft's more flexible, and even included the surface pen stylus, can be arbitrary graffiti and drawing. Of course, in basic mode, it can also be a touch screen and surface Pen, but still a bit shaky.
Another type of input is the trackpad, a further in
Unity3D Surface Shader (Surface Shader) data integration, unity3dshader1. Shader surface coloring machine syntax
The Surface Shader of Unity is a method of code generation. It is much easier to use it to write a light Shader than to use a low-level vertex/pixel Shader program.
2. Compile a Shader for Grayscale Effect
Set the steps as follows:
1. (Win8.1 system) from the right side of the screen edge to slide, click the settings.
2. Click to change the computer settings--pc and equipment, and then click Bluetooth.
3. Make sure the Bluetooth switch is turned on.
4. Press and hold the surface touch pen button for 7 seconds until the middle end of the pen starts blinking.
5. When the surface pen appears on the Bluetoot
Surface Shader Illumination ExampleHere are some examples of custom lighting models and surface shaders. The usual surface shader examples are here.Because delayed illumination does not perform well in some custom light-to-material lighting models, in most of the following examples, we have shader compiled into forward rendering only.Diffuse reflectance (diffuse)

Depending on your preferences, you can select the left or right side of the screen to start the surface, if you want to set the surface side screen position, follow these steps:
1. Under the Standby page, click "Application".
2. Click "Set".
3. Slide up the screen and click on the "Surface side screen".
4. Slide up the screen and cl
I have rarely explained this principle easily and clearly. I have tried to explain the technical problem on my own and hope that my confused friends can understand the principle. here, I assume that you have a good understanding of the geometric organization of quake3, so I will go directly to the topic to explain the principle of transformation. Some important concepts in quake3 Code may be introduced during the explanation. first, we will explain two very important conditions: 1. The pla

In the recent extensive evaluation of surface Pro 4 and Surface Book, the lack of a dedicated brightness modifier on the physical keyboard has become one of the "drawbacks" identified by each. In fact, this is the legacy of surface Pro 3, but it doesn't mean the keyboard has no way to adjust the brightness. Surface Pro
the custom lighting model in Surface shaderWhen you're writing surface Shaders, you're describing the properties of a surface (reflection color, normals ...). ), and the interaction of light is calculated by a light model. The built-in lighting models have Lambert (diffuse illumination) and blinnphong (specular illumination).Sometimes, you might want to use a cus
