What is Gl_line_strip?
GL_LINE_STRIP: The adjacent vertices are considered lines. Thus, if you pass n vertices, you will get n-1 lines. If the user only specifies 1 vertex, the drawing command is ignored. GL_LINE_LOOP: As line strips, except that the first and last vertices are also used as a line. Thus, you get n lines for n input vertices.
What is primitive restart?
Primitive Restart. Primitive restart functionality allows you to tell OpenGL that a particular index value means, not to source a vertex at that index, but to begin a new Primitive of the same type with the next vertex. In essence, it is an alternative to glMultiDrawElements (see below).
What is GLfloat?
h defines GLfloat, it defines it a set size that does not change per system. This helps keeps openGL crossplatform compilant. openGL uses RGB values to define a color. (Red, Green, Blue), also your can add a transparency value to a color also, which is the fourth value.
What is the difference between glDrawArrays and glDrawElements?
glDrawArrays submits the vertices in linear order, as they are stored in the vertex arrays. With glDrawElements you have to supply an index buffer. Indices allow you to submit the vertices in any order, and to reuse vertices that are shared between triangles.
What is the symbol for linewidth?
Formula symbol: Δν, Δλ. Units: Hz, nm. How to cite the article; suggest additional literature. The linewidth (or line width) of a laser, e.g. a single-frequency laser, is the width (typically the full width at half-maximum, FWHM) of its optical spectrum.
What is the linewidth of a transition?
The linewidth of a transition is often related to a Q factor, which is the frequency divided by the linewidth. The RP Photonics Buyer’s Guide contains 19 suppliers for linewidth measurement equipment.
What is the difference between line width and bandwidth?
Line width: Line width bandwidth is a physical quantity related to space and time. 2). Bandwidth: Bandwidth is a measure of the frequency spectrum occupied by a signal, which can be regarded as a physical quantity related to space. In the optical path, what is the effect of placing a half wave plate and a polarizer in front of the laser?
What is the linewidth of a light beam?
Similarly, other spectral lines e.g. from gas discharge lamps have certain linewidths, which can depend on the operation conditions. The linewidth of a light beam is strongly (but non-trivially) related to the temporal coherence, characterized by the coherence time or coherence length .
