WebSep 19, 2016 · I have an array of structs in C++ which I’d like to send to my fragment shader by using an uniform buffer object. As much I managed to gather during these past days, my code is currently in this format: C++: struct Light { glm::vec4 Position; glm::vec4 Color; float Linear; float Quadratic; float Radius; }; const GLuint NR_LIGHTS = 99; Light ... Structs are defined much like C++ (note: the C-style typedef struct *{} syntax is notsupported). GLSL does not support anonymous structures (ie: structs without a type name), and structs must have at least one member declaration. Structs cannot be defined within another struct, but one struct can use another … See more Basic types in GLSL are the most fundamental types. Non-basic types are aggregates of these fundamental types. See more Variables of almost any type can be initialized with an initial value. The exceptions are: 1. Input or output qualified variables. 2. Any variable of a opaque typetype. 3. … See more Basic types can be grouped into sequences of those elements, called arrays. This generally works like in C/C++, but there are some limitations. First and foremost is that … See more Groups of variables that use the input, output, or uniform type qualifierscan be grouped into named blocks.

Web6.3.2 Data Structures. A GLSL program can define new types using the struct keyword. The syntax is the same as in C, with some limitations. A struct is made up of a sequence of named members, which can be of different types. The type of a member can be any of the built-in types, an array type, or a previously defined struct type.

Web1. I have the same issue, windows 8.1x64 R9290. The shader cannot read the length of a buffer. I got round this by creating another SSBO with containing the lengths of the Light array. I don't need to do this on Nvidia or Intel chips. Another issue is that vec3 types didn't seem to work due to memory padding, so I manually pad all data as a vec4.

WebJul 23, 2013 · What I want is to have an array of structs in the shader which I can bound dynamically per frame.
