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.
Examples
var s=taccgl.ssc(); s.color = function () {return "col = vec3(1.0,0.0,0.0);" } var b=taccgl.actor("testimg").sc(s).dur(2).start(); | RUN |
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.
Examples
var s=taccgl.ssc('ShaderSample1');var b=taccgl.actor("testimg").sc(s).dur(2).start(); | RUN |
<script id="ShaderSample1" type="x-gsgl/x-shader"> :color col = vec3(1.0,0.0,0.0); </script> |
|
These methods are called by compile.
