GLSL Half (floating point) attribute type

Question

I have been trying to get a 16bit float (half-floating point) as an attribute into my GLSL vertex shader. It won\'t let me compile saying:

error C7506: OpenGL do         


        

Answer 1

In the absence of a MCVE demonstrating otherwise I assume you tried something like:

half float aHalfFloat;

However, "half" is a reserved keyword in #version 410:

OpenGL Shading Language 4.10 Specification, page 15 (emphasis mine):

The following are the keywords reserved for future use. Using them will result in an error:
