.SH "Detailed Description"
.PP 
Shaders are programs that run on the graphics processor and replace the formerly fixed OpenGL pipeline\&. 

\fBCoin-2\&.5\fP added support for Shaders\&. Shaders replace the fixed function vertex and fragment processing in OpenGL by letting the user define the processing that takes place at key points in the OpenGL pipeline\&. Vertex shaders handle the operations that occur on each vertex, while fragment shaders handle the operations that occur on each pixel\&. The \fBSoShaderProgram\fP node in Coin provides a convenient way of specifying the code for vertex and fragment shaders\&.
.PP
\fBCoin-3\&.0\fP expanded upon the shader support by adding support for OpenGL Vertex Attributes\&. When using shaders, programmers are no longer limited to the set of attributes that OpenGL defines (glColor, glNormal, glTexCoord etc\&.) You can now define your own per-vertex data and pass them to the shaders using the \fBSoVertexAttribute\fP node\&.
