glUniformMatrix3fv Function

GL_APICALL void GL_APIENTRY glUniformMatrix3fv(
     GLint location,
     GLsizei count,
     GLboolean transpose,
     const GLfloat * value
);

	Name	Description
in	location	Location of uniform variable
in	count	The number of elements in the GL_FLOAT_VEC3 array-type uniform being configured.
in	transpose	Whether to load the transpose
in	value	Array storing the values to set

No values are returned.

Sets the value of GL_FLOAT_VEC3-type uniform variable arrays in the vertex shader or geometry shader.

This function changes the values of a (count × 3) number of arrays. Set transpose to GL_TRUE when taking the transpose. For value, specify an array of values to set in the uniform. Specify value using an array of (count × 9) GLfloat values.

Calls to this function are ignored when location is -1.

This function generates the following errors.

GL_INVALID_VALUE	The count argument is negative.
GL_INVALID_OPERATION	The location argument is not a location in the current program.
GL_INVALID_OPERATION	There is no current program object.
GL_INVALID_OPERATION	This function was called on a location with a different data type or component count.
GL_INVALID_OPERATION	The uniform array count is less than three times the sum of count and the offset added to the location obtained from glGetUniformLocation.
