Public Functions

virtual std::string getSrc() const = 0

Returns GLSL source code for a function with the prototype vec4 calculateColor() It may optionally also include a definition for a uniform samplerBuffer If a uniform samplerBuffer is included, it’s identifier should be returned by getSamplerName()

inline virtual std::string getSamplerName() const

If the shader source contains a samplerBuffer definition (e.g. of a single float/int) This should be the identifier so that the buffer can be bound to it Otherwise empty string

inline virtual std::string getAgentVariableName() const

If the shader source contains a samplerBuffer definition This should be the name of the agent variable so that the buffer can be bound to it Otherwise empty string

inline virtual std::type_index getAgentVariableRequiredType() const

If the shader source contains a samplerBuffer definition This should be the type of the agent variable so that the buffer can be bound to it Otherwise void typeid is returned.
