It simply clarifies the accuracy of various GLSL functions. Which is the first extension that defines no value, API functions nor GLSL functions.
OpenGL 4.1 also integrates GL_ARB_shader_precision This behaviour isn’t new as GL_ARB_gpu_shader_fp64 introduced it for double uniforms. This extension ensures that this precision will be kept.Īn important detail is that double attribute can consume more than one location which will have some consequences in the software design. OpenGL already provides such support but usually the double values are converted to single precision floating point values. Which trivially adds support for double precision floating point scalars and vectors for the vertex attributes. OpenGL 4.1 includes the new extension called GL_ARB_vertex_attrib_64bit' The proper OpenGL 4 hardware features: double float vertex attributes and operations precision In this article we are going to have a closer look at OpenGL 4.1 and the new extensions that come along with its release.
