hey I wanna create a cube texture class and have a noob question; should I set the texture parameters single time after binding the texture as GL_TEXTURE_CUBE_MAP or should I set them for each element such as GL_TEXTURE_CUBE_MAP_POSITIVE_X, etc. with corresponding targets.

an open source GLU replacement library. Much more modern than GLU.
float matrix[16], inverse_matrix[16];
glhLoadIdentityf2(matrix);
glhTranslatef2(matrix, 0.0, 0.0, 5.0);
glhRotateAboutXf2(matrix, angleInRadians);
glhScalef2(matrix, 1.0, 1.0, -1.0);
glhQuickInvertMatrixf2(matrix, inverse_matrix);
glUniformMatrix4fv(uniformLocation1, 1, FALSE, matrix);
glUniformMatrix4fv(uniformLocation2, 1, FALSE, inverse_matrix);
