Web12 de jul. de 2012 · The spec says gl_PointSize is clamped to implementation specific limits. Seems on any recent NVidia GPU, if there are any limits, they’re pretty big. Also, they cull as quads, not infinitely small points, which while it violates the spec, is more useful behavior. mhagain July 12, 2012, 5:18am #3 WebAs such, we scored expo-gl popularity level to be Recognized.

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. This is not defined by the GL … Ver mais http://15462.courses.cs.cmu.edu/spring2024content/lectures/00_opengl/00_opengl_slides.pdf
