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

void glGetFloatv(int pname,
               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,
