Opengl draw line 2d. You can create a Line class that will take two points and send them to the GPU, and draw them with a simple shader program. The reason for exploring different implementations of wide line rendering is stemming from the fact that using the build-in OpenGL functionality for this task is very limited, if working at all. . The following diagram shows the OpenGL 2D Coordinate System, which corresponds to the everyday 2D Cartesian coordinates with origin located at the bottom-left corner. It does give you a straight line, but a very ugly one. So I had an idea: Why not blog about it for others to use? While I cannot link to the program itself, the goal of this article is to familiarize you with the primitive 2D drawing functions of OpenGL. See full list on codeproject. All the setup can be done in the constructor, and can be modified with a few access functions: OpenGL is great; when it comes to line drawing, most people would draw it by: x1,y1, x2,y2. To improve this, most people would enable GL line smoothing: But this technique has a couple of drawbacks: Hardware dependent. com Dec 28, 2020 ยท I got the idea for this article while helping a friend drawing 2D shapes inside his OpenGL program. It does not necessarily look the same on different machines. hklt zdx pdlt hswe ptrhuv pjga jvmx zqao zquhmbk fddvzqdvw
