ShaderGeneration Methods

There are various methods used for generation of the shader source code. Each of these methods generate part of the source and return that as a string. You can override these methods in order to customize the shaders.


var s=taccgl.ssc();
s.color = function () {return "col = vec3(1.0,0.0,0.0);" }

In the above example the color method is overridden, returning shader code "col = vec3(1.0,0.0,0.0)" which assign the color red to each pixel.

This can however be written in a much more readable way by supplying the id of an HTML script element to the ssc method. The script can contain one or more sections, each starting with a colon ':' followed by the name of a method. This will override the named method to generate the following code into the shader.


var s=taccgl.ssc('ShaderSample1');var"testimg").sc(s).dur(2).start(); RUN
<script id="ShaderSample1" type="x-gsgl/x-shader">
col = vec3(1.0,0.0,0.0);
These methods are called by compile.
