You can use any combination of up to 4 of the letters to create a vector (of the same basic type) of that length. So otherVec.zyy is a vec3, which is how we can initialize a vec3 value with it. Any combination of up to 4 letters is acceptable, so long as the source vector actually has those components. Ver mais Basic types in GLSL are the most fundamental types. Non-basic types are aggregates of these fundamental types. Ver mais Structs are defined much like C++ (note: the C-style typedef struct *{} syntax is notsupported). GLSL does not support anonymous structures … Ver mais Basic types can be grouped into sequences of those elements, called arrays. This generally works like in C/C++, but there are some … Ver mais Variables of almost any type can be initialized with an initial value. The exceptions are: 1. Input or output qualified variables. 2.

Web1 de jun. de 2010 · The transformation functions are mapped on the deprecated OpenGL transform functions: I guess: glm::mat4 M = glm::scale(glm::mat4(1.0), glm::vec3(v)); Due to the template implementation, I can see some trouble for the compiler to actually perform an implicit cast. By the way, implicit cast are evil! http://www.learnopengles.com/understanding-opengls-matrices/
