Varying structure is a great GLSL feature that should be supported as Fragment outputs can only be float,įloating-point vectors, signed or unsigned integers or integer vectors, or arrays of any these. To use centroid out, sample out, or patch out in a fragment shader. Vertex shader inputs can also form arrays of these types, but not structures.įragment outputs output per-fragment data and are declared using the out storage qualifier.
Varying structures have only limitations on input of the vertex shader and output of the fragment shader. Signed or unsigned integers or integer vectors, or arrays or structures of any these. PervertexĪnd per-patch output variables can only be floating-point scalars, floating-point vectors, matrices, Per-patch output variables are declared using the patch out storage qualifier. Output variables are arrayed (see arrayed under 4.3.4 Inputs) and declared using out or centroid Tessellation control shader output variables are may be used to output per-vertex and per-patch data. OpenGL Shading Language 4.10 specification section 4.3.6 Outputs Vectors, or arrays or structures of any these. Output variablesĬan only be floating-point scalars, floating-point vectors, matrices, signed or unsigned integers or integer It is an error to use patch out in a vertex, tessellation evaluation, or geometry shader. Using the out, centroid out, or sample out storage qualifiers, or the deprecated varying storage qualifier.
Vertex, tessellation evaluation, and geometry output variables output per-vertex data and are declared OpenGL Shading Language 4.10 specification section 4.3.4 Inputs Point scalars, floating-point vectors, matrices, or arrays or structures of these
That's why I called these warnings "offensive" and following some proofs:įragment inputs can only be signed and unsigned integers and integer vectors, floating NVidia drivers still doesn't support varying structures but worse the drivers reportĪn error that claims through an error message that varying structures are not supported in OpenGL.īut they should support varying structure according to the spec. It probably only means that AMD has just started working on the OpenGL 4.1 drivers. Unfortunately, nothing seems to work yet. On AMD side, the Catalyst 10.10c provides an OpenGL 4.1 drivers for the first time but I believe it happens as accident:įirst Catalyst 10.10a were released with the OpenGL 4.1 drivers but without any information then the Catalyst 10.10c has been release with OpenGL 4.1 beta support in the release note. On nVidia side, the OpenGL 4.1 implementation has reach the stable drivers as it fixes a lot of issues and seems to work pretty well. OpenGL 4.1 drivers status: A step up!
