There are three kinds of entities in OpenGL: dots, lines, triangles. For Lines, OpenGL provides us with three ways to draw lines: ① Draw Segment (lines): The so-called line segment is not connected to some of the set of lines. ② Draw Line (Line_strip): A line that is connected but not closed. ③ Draw line Ring (Line

Basic Introduction to CAD new drawing layer and define color and line width When we get the CAD drawing, whether it is the building plan or the structure, we can see that different structures have different colors, and the text can become different colors. In fact, this is the designer in different layers modify the characteristics of

-point increment, the accumulation of rounding error causes the pixel position calculated for the longer segment to deviate from the actual segment. And the rounding and floating-point operations in the process are still time consuming. We can improve the performance of the DDA algorithm by separating the increment m and 1/m into integers and fractional parts, so that all calculations are simplified to integer operations. The method of calculating 1/m increments with integer steps is discussed l

Introduction A line chart is generally used to describe a variable of one-dimensional variables as a continuous variable, which is usually time. In other words, a line chart is best suited to describe changes in time series data. Of course, with the change of discrete variables is also possible, but this discrete variable must be ordered. Draw a line chart A basi

How to choose the type and color of the MATLAB drawing line? Matlab is a very powerful mapping function, so it is widely used in scientific experiments and social research. How do we choose the type of line when we draw a graphic? For example, we need dotted lines, star dots. Or how do you set the color of the line? He

To draw a graph in Windows, you must first define the DC (device context) and directly use the graphics class in. net. Assign a drawing tool, such as a paint brush, and call the drawing function to draw the image. Remember to release graphics, drawing tools, and other objects after drawing. Because image objects occupy

The text actually also uses the layer effect to replace 1.1 points to depict the lining line, this technology previously in the station cool to see a designer summed up, this is the original link, I do not have more words to decorate. I always ask everybody, why like to use Shadow, with shadow feel added effect is good-looking? There is a shadow, then where is your light source, both add angle of the same shadow, then how many light

The first half of the junior year, and met this proficient (funny) Delphi teacher, people are very good actually.About his resolution of The Spit Groove Ah, the praise of Delphi Ah, are very humorous. In addition, I appreciate his maintenance of his notebook "Dell i7 920XM Workstation estimate".Well, then he's going to class, basically knocking on the Code (practice). He decided to use C + + Builder 4 "later on, in order to cater to our professional not having studied Pascal's condition.It's a l

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
