\brief Functions and types that GLSL does not provide, but are useful to have.
|
||||
|
||||
Core extensions differ from \ref gtx "experimental extensions" in that core extensions
|
||||
are fairly stable. The API for experimental extensions is expected to change
|
||||
significantly between versions.
|
||||
|
||||
Even if it's highly unrecommended, you can bring all of the extensions, by
|
||||
including <glm/ext.hpp>. Otherwise, you will have to include each extension
|
||||
by including a specific file.
|
||||
\brief Extensions develop and maintain by Mathieu [matrem] Roumillac (http://www.opengl.org/discussion_boards/ubbthreads.php?ubb=showprofile&User=22660).

\brief Defines functions that generate common transformation matrices.

The matrices generated by this extension use standard OpenGL fixed-function

conventions. For example, the lookAt function generates a transform from world
|
||||
space into the specific eye space that the projective matrix functions (
|
||||
perspective, ortho, etc) are designed to expect. The OpenGL compatibility
|
||||
specifications defines the particular layout of this eye space.

You must include <glm/gtc/matrix_transform.hpp> to get this functionality.

\defgroup gtc_type_ptr Pointer Access Core Extension
|
||||
\ingroup gtc
|
||||
|
||||
\brief Used to get a pointer to the memory layout of a basic type.
|
||||
|
||||
This extension defines an overloaded function, glm::value_ptr, which
|
||||
takes any of the \ref core_template "core template types". It returns
|
||||
a pointer to the memory layout of the object. Matrix types store their values
|
||||
in row-major order.
|
||||
|
||||
This is useful for uploading data to matrices or copying data to buffer objects.
|
||||
|
||||
Example:
|
||||
|
||||
\code
|
||||
#include <glm/glm.hpp>
|
||||
#include <glm/gtc/type_ptr.hpp>
|
||||
glm::vec3 aVector(3);
|
||||
glm::mat4 someMatrix(1.0);
|
||||
|
||||
glUniform3fv(uniformLoc, 1, glm::value_ptr(aVector));
|
||||
glUniformMatrix4fv(uniformMatrixLoc, 1, GL_FALSE, glm::value_ptr(someMatrix));
|
||||
\endcode
|
||||
|
||||
You must include the file <glm/gtc/type_ptr.hpp> to get this functionality.
