'''OpenGL extension ARB.transpose_matrix
This module customises the behaviour of the OpenGL.raw.GL.ARB.transpose_matrix to provide a more Python-friendly API
Overview (from the spec) New functions and tokens are added allowing application matrices stored in row major order rather than column major order to be transferred to the OpenGL implementation. This allows an application to use standard C-language 2-dimensional arrays (m[row][col]) and have the array indices match the expected matrix row and column indexes. These arrays are referred to as transpose matrices since they are the transpose of the standard matrices passed to OpenGL. This extension adds an interface for transfering data to and from the OpenGL pipeline, it does not change any OpenGL processing or imply any changes in state representation.
The official definition of this extension is available here: http://www.opengl.org/registry/specs/ARB/transpose_matrix.txt ''' from OpenGL import platform, constants, constant, arrays from OpenGL import extensions, wrapper from OpenGL.GL import glget import ctypes from OpenGL.raw.GL.ARB.transpose_matrix import * ### END AUTOGENERATED SECTION for typ,arrayType in ( ('d',arrays.GLdoubleArray), ('f',arrays.GLfloatArray), ): for function in ('glLoadTransposeMatrix','glMultTransposeMatrix'): name = '%s%sARB'%(function,typ) globals()[name] = arrays.setInputArraySizeType( globals()[name], 16, arrayType, 'm', ) del function,name del typ,arrayType
