We will also learn to place 3D cameras, set 3D "lenses" and put your triangles into a world with other three-dimensional objects.Draw PipelineA simple drawing line as shown: need to pas

To the users of Photoshop software to explain the detailed interpretation of the drawing of two times the figure pencil line of the production of the tutorial. Tutorial Sharing: First of all international practice, take a picture to copy again. (can prevent the damage cannot find the original image, to get the best copy and then start editing) Copy again and use Ctrl+i to

In the process of developing county power grid dispatching automation system, the author encounters a problem to draw the primary wiring diagram of power system. As the power system wiring diagram is more complex, there are some special symbols, such as transformer symbols, switch symbols, and so on, with general programming methods to draw more difficult, therefore, the author uses C language to develop a hand-drawn power system wiring diagram of the keyboard

Today in the project there is a player attribute radar drawing requirements, when I put five dimensions corresponding to the number of points group into the Drawpoly function, appeared the following phenomenon, check for half a day, the online no related questions answered, I asked in the group, there is a big God said this is the dot of the array has coincident, so there will be such a problem , I tested the next, it is true, and then I made a judgme

Matplotlib's official website address: http://matplotlib.org/ When using Python to do data processing, a lot of the data we don't seem to be intuitive, and sometimes it's graphically shown that it's easier to observe the changing characteristics of the data, and so on. Matplotlib is a Python 2D drawing library that generates publishing quality-level graphics in a variety of hard copy formats and cross-platform interactive environments. It provides a c

Draw Pipeline The function of drawing pipelining is to create a 2D image in a given 3D scene and a geometric description of the virtual camera in the specified viewing direction. 1. Model representation In real life, any object can be represented by a triangular mesh approximation. Triangular meshes are the basic units for building object models. Note: line and point primitives are not very useful for mod

Draw_point (x0, y0, color); is a painting point function I wrote. You don't need to worry about it. The key is the painting line algorithm. /* Draw line functionThis algorithm is an optimization algorithm for bresenham's line-drawing algorithm. It removes multiplication and division operations to make the operation fas

Last time we used the two-line brush tool to create the outline effect of the chalk word, this time we use the blending mode plus filters to create the perfect outline effect of the font. Let's take a look at the effect chart: 1. Create a new 1000x500 canvas, fill the #d7c7a8 2. Then we typed the word, I used the "Hall Fetica" Font (click here to download), of course, you can also use other fonts, but pay attention to choose

Comments: Drawing an ellipse in a Canvas is a common requirement, but this method has not been implemented in most browsers currently. Therefore, the arc or arcTo method is often used to draw an ellipse in combination with scale deformation, if you are interested, you can understand it and hope it can help you. Drawing an ellipse in a Canvas is a common requirement. The ellipse method is added to the new HT

This article mainly introduces Effect: the figure is moved once every five seconds (in fact, a new figure is drawn) to display the monitored cpu information. The pastCpuInfomation function is used to display a line chart. The updateCpuPic function removes the graph 5 seconds ago and draws a New Graph Based on the existing data. The updateCpuInfomation function adds the latest vertex to the array storing the broken

Python implements the method of drawing a straight line cursor between two coordinate axes in matplotlib This example describes how to draw a straight line cursor between two coordinate axes in matplotlib using Python.

Breaseman algorithm to draw straight line algorithm formula derivationThe Bresenham algorithm is the algorithm designed for the "display (screen or printer) system by Pixel", which makes all the integers in the process of seeking straight line, thus greatly increases the computational speed.Self-feeling, the Breaseman algorithm is the biggest reference, is the use of the formula of stepping, cleverly avoid

seems to be empty, but attentive readers will find some black dots on the image. 6. Use the "minimum" filter for the background copy layer with a radius of 1 pixels, that is, this insignificant change created two layers of subtle nuances like plain order, pulling out the edges of the sharp contrast and ignoring the rest of the less intense contrast. Hint: It should be pointed out that the traditional line-d
