 ## Geometry Shader

 

-Gemoetry shaders were introduced in OpenGL 3.2, they can produce vertices

+Geometry shaders were introduced in OpenGL 3.2, they can produce vertices

 that are send to the rasterizer. They can also change the primitive type e.g.

 they can take a point as an input and output other primitives.

 Geometry shaders are inbetween the vertex and the fragment shader.
