abstract IEnumerable<string> Derm.Render.BaseShaderAttributes.Bindings [get]

Current attributes bindings.

Reimplemented in Derm.Render.ShaderAttributes, and Derm.Render.ShaderAttributesProxy.

IEnumerable<string> Derm.Render.BaseShaderAttributes.Defines [get]

Obtain a symbols list depending on current attributes.

Most of ShaderPrograms can handle a different set of attributes. This mean that the shaders composing the ShaderProgram can be adapted depending on the current available attributes.

This is usefull in the case it's needed to run the ShaderProgram with different

Instead of leave to shader developer the effort of defining preprocessor symbols to include/exclude certain shader code depending on current inputs, the ShaderAttributes offers this routine to obtain a list of preprocessor strings dependent on current available attributes.

The defined symbols have the for "HasSymbolName", where symbol name is derived by removing the first 3 letters of the input binding name. This because suppose input bindings starts with 2 letters and one underscore (i.e.: ds_VertexPosition will produce HasVertexPosition symbol).
