glUniform2fint
glUniform2fv is a function in the OpenGL API used to set the value of a uniform variable in a shader program. Uniform variables are used to pass data from the application to the shaders, such as transformation matrices, light positions, or material properties. The function is specifically designed to set the value of a uniform variable that is a two-component floating-point vector (vec2).
The function prototype for glUniform2fv is as follows:
void glUniform2fv(GLint location, GLsizei count, const GLfloat *value);
The parameters for this function are:
location: The location of the uniform variable in the shader program. This is obtained using the glGetUniformLocation
count: The number of vec2 values to be set.
value: A pointer to an array of GLfloat values representing the vec2 values to be set.
The function sets the value of the uniform variable at the specified location to the values provided
It is important to note that the uniform variable must be of type vec2 in the shader
In summary, glUniform2fv is a useful function in the OpenGL API for setting the value of a
