\brief Functions and types that the GLSL specification doesn't define, but useful to have for a C++ program.
|
|
|
|
GTC extensions aim to be stable.
|
|
|
|
Even if it's highly unrecommended, it's possible to include all the extensions at once by
|
|
including <glm/ext.hpp>. Otherwise, each extension needs to be included a specific file.

\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.

\defgroup gtc_type_ptr GLM_GTC_type_ptr: Memory layout access.
|
|
\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 column-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
|
|
|
|
<glm/gtc/type_ptr.hpp> need to be included to use these functionalities.
