Method Detail

glGetFloatv

void glGetFloatv(int pname,
                 FloatBuffer params)
Copy the named matrix into the given storage.

Parameters:
pname - GL_MODELVIEW_MATRIX, GL_PROJECTION_MATRIX or GL_TEXTURE_MATRIX
params - the FloatBuffer's position remains unchanged, which is the same behavior than the native JOGL GL impl

glGetFloatv

                 float[] params,
                 int params_offset)
Copy the named matrix to the given storage at offset.

Parameters:
pname - GL_MODELVIEW_MATRIX, GL_PROJECTION_MATRIX or GL_TEXTURE_MATRIX
params - storage
params_offset - storage offset

glGetIntegerv

void glGetIntegerv(int pname,
                   IntBuffer params)
glGetIntegerv

Parameters:
pname - GL_MATRIX_MODE to receive the current matrix mode
params - the FloatBuffer's position remains unchanged which is the same behavior than the native JOGL GL impl

glGetIntegerv

void glGetIntegerv(int pname,
                   int[] params,
