3D Primtives in OpenGL
OpenGl Graphics library or OpenGl toolkit provides different API and methods to draw various 2d and 3d objects. In this post we will able show case you the basic 3d shapes. These 3d primitive can be drawn by calling the predefined methods or function in OpenGL.
What are 3D Primtives in OpenGL?
Like points,lines , traingle and polyogn in 2d we have primitives in 3d as well written in OpenGL itself. The library provide us easy access to draw the 2d Objects with one line of code. We can use 2d primitives to draw the 3d objects but in OpenGL we have predefined code for 3d objects. We can overrides them as well. These code help quickly draw the 3d objects without writing alots of code for them.
There are many 3D objects defined but we mentioned you the 3d basics ones - Sphere, Cube (cuboid), Cone, Torus, Icosahedron and Teapot . These 3d objects can be drawn easily by calling the function from OPenGL graphics library, with some input likes radius, length, height and width etc.
