There is only one kind of point primitive: GL_POINTS. This will cause OpenGL to interpret each individual vertex in the stream as a point. Points that have a Texturemapped onto them are often called "point sprites". Points are rasterized as screen-aligned squares of a given window-space size. The size can … Ver mais A vertex stream is an ordered list of vertices. Where this stream comes from depends on when Primitive Assemblyis taking place and which stages of the rendering pipeline are … Ver mais A triangle is a primitive formed by 3 vertices.

If you use GL_RGB8, OpenGL can promote it to GL_RGBA8 internally, with the implementation filling in a 1.0 for the alpha. By querying this, you can detect when such image format modification will happen. WebYou can run your draw methods several times with different inputs before swapping the buffers. But in order to use OpenGL efficiently for plotting zillions of points, what it is made for - you need to tell more about the nature of those points.
