With doom3 shaders you can have mathimatical equations as values. My question is does anyone know how to turn a mathimatical equation (stored in a string) into an integer/float?

Sample Shader:

You have to write an expression parser, if you need to evaluate expressions only once, you can compute the result "on the fly", else it will be more efficient to create p-code from the string.

<-- Clueless.

The values need to be parsed each time the shader is reloaded (which is when levels reload, etc. Places where speed doesn't rearly matter)
