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. It is the 2D shape with the smallest number of vertices, so renderers are typically designed to render them. Since it is created from only 3 vertices, it is also guaranteed to be … Ver mais There are 3 kinds of line primitives, based on different interpretations of a vertex stream. 1. GL_LINES: Vertices 0 and 1 are considered a line. Vertices 2 and 3 are considered a line. … Ver mais A quad is a 4 vertex quadrilateral primitive. The four vertices are expected to be coplanar; failure to do so can lead to undefined results. A quad is typically rasterized as a pair of triangles.
