py operators - don't use the screen as an operators ID anymore, screen's don't store operator instances and operator functions have access to the context if they need the current screen. also add some more py api file descriptions.

VideoTexture: improvements to image data access API. - Use BGL buffer instead of string for image data. - Add buffer interface to image source. - Allow customization of pixel format. - Add valid property to check if the image data is available. The image property of all Image source objects will now return a BGL 'buffer' object. Previously it was returning a string, which was not working at all with Python 3.1. The BGL buffer type allows sequence access to bytes and is directly usable in BGL OpenGL wrapper functions. The buffer is formated as a 1 dimensional array of bytes with 4 bytes per pixel in RGBA order. BGL buffers will also be accepted in the ImageBuff load() and plot() functions. It is possible to customize the pixel format by using the VideoTexture.imageToArray(image, mode) function: the first argument is a Image source object, the second optional argument is a format string using the R, G, B, A, 0 and 1 characters. For example "BGR" means that each pixel will be 3 bytes, corresponding to the Blue, Green and Red channel in that order. Use 0 for a fixed hex 00 value, 1 for hex FF. The default mode is "RGBA". All Image source objects now support the buffer interface which allows to create memoryview objects for direct access to the image internal buffer without memory copy. The buffer format is one dimensional array of bytes with 4 bytes per pixel in RGBA order. The buffer is writable, which allows custom modifications of the image data. v = memoryview(source) A bug in the Python 3.1 buffer API will cause a crash if the memoryview object cannot be created. Therefore, you must always check first that an image data is available before creating a memoryview object. Use the new valid attribute for that: if source.valid: v = memoryview(source) ... Note: the BGL buffer object itself does not yet support the buffer interface. Note: the valid attribute makes sense only if you use image source in conjunction with texture object like this: # refresh texture but keep image data in memory texture.refresh(False) if texture.source.valid: v = memoryview(texture.source) # process image ... # invalidate image for next texture refresh texture.source.refresh() Limitation: While memoryview objects exist, the image cannot be resized. Resizing occurs with ImageViewport objects when the viewport size is changed or with ImageFFmpeg when a new image is reloaded for example. Any attempt to resize will cause a runtime error. Delete the memoryview objects is you want to resize an image source object.

bgl new methods (for glsl shaders - #version 120) ** I did not update rst docs. I will post on the quick-hack list. If no one volunteers to do it, I have it done before next release. ** this patch add the barebone functions to do glsl shaders in an addon. For simplicity sakes it supports old GLSL, but not all the new modern methods (glBindFragDataLocation, ...). It should be enough to make an addon to help with bge 2d filters. I'm using this with a 3dview callback and it's working nicely: self._handle = context.region.callback_add(draw_callback_px, (self, context), 'POST_VIEW') I was considering not to commit this patch due to it not covering all OpenGL new methods. But frankly it's not the first time bgl is expanded upon individual needs (guilty of that myself). If a python developer knows enough to use OpenGL and need new functions, s/he should also be able to patch Blender for that, so I see no problems here. Another solution is to move to PyOpenGL or similar any soon. glShaderSource implemented differently than opengl standards. It's taking one source at a time (instead of an array of sources). This is similar with PyOpenGL solution. glActiveTexture glAttachShader glCompileShader glCreateProgram glCreateShader glDeleteProgram glDeleteShader glDetachShader glGetAttachedShaders glGetProgramInfoLog glGetProgramiv glGetShaderInfoLog glGetShaderiv glGetShaderSource glGetUniformLocation glIsProgram glIsShader glLinkProgram glShaderSource glUniform1f glUniform2f glUniform3f glUniform4f glUniform1fv glUniform2fv glUniform3fv glUniform4fv glUniform1i glUniform2i glUniform3i glUniform4i glUniform1iv glUniform2iv glUniform3iv glUniform4iv glUniformMatrix2fv glUniformMatrix3fv glUniformMatrix4fv glUniformMatrix2x3fv glUniformMatrix3x2fv glUniformMatrix2x4fv glUniformMatrix4x2fv glUniformMatrix3x4fv glUniformMatrix4x3fv glUseProgram glValidateProgram

VideoTexture: improvements to image data access API. - Use BGL buffer instead of string for image data. - Add buffer interface to image source. - Allow customization of pixel format. - Add valid property to check if the image data is available. The image property of all Image source objects will now return a BGL 'buffer' object. Previously it was returning a string, which was not working at all with Python 3.1. The BGL buffer type allows sequence access to bytes and is directly usable in BGL OpenGL wrapper functions. The buffer is formated as a 1 dimensional array of bytes with 4 bytes per pixel in RGBA order. BGL buffers will also be accepted in the ImageBuff load() and plot() functions. It is possible to customize the pixel format by using the VideoTexture.imageToArray(image, mode) function: the first argument is a Image source object, the second optional argument is a format string using the R, G, B, A, 0 and 1 characters. For example "BGR" means that each pixel will be 3 bytes, corresponding to the Blue, Green and Red channel in that order. Use 0 for a fixed hex 00 value, 1 for hex FF. The default mode is "RGBA". All Image source objects now support the buffer interface which allows to create memoryview objects for direct access to the image internal buffer without memory copy. The buffer format is one dimensional array of bytes with 4 bytes per pixel in RGBA order. The buffer is writable, which allows custom modifications of the image data. v = memoryview(source) A bug in the Python 3.1 buffer API will cause a crash if the memoryview object cannot be created. Therefore, you must always check first that an image data is available before creating a memoryview object. Use the new valid attribute for that: if source.valid: v = memoryview(source) ... Note: the BGL buffer object itself does not yet support the buffer interface. Note: the valid attribute makes sense only if you use image source in conjunction with texture object like this: # refresh texture but keep image data in memory texture.refresh(False) if texture.source.valid: v = memoryview(texture.source) # process image ... # invalidate image for next texture refresh texture.source.refresh() Limitation: While memoryview objects exist, the image cannot be resized. Resizing occurs with ImageViewport objects when the viewport size is changed or with ImageFFmpeg when a new image is reloaded for example. Any attempt to resize will cause a runtime error. Delete the memoryview objects is you want to resize an image source object.

bgl new methods (for glsl shaders - #version 120) ** I did not update rst docs. I will post on the quick-hack list. If no one volunteers to do it, I have it done before next release. ** this patch add the barebone functions to do glsl shaders in an addon. For simplicity sakes it supports old GLSL, but not all the new modern methods (glBindFragDataLocation, ...). It should be enough to make an addon to help with bge 2d filters. I'm using this with a 3dview callback and it's working nicely: self._handle = context.region.callback_add(draw_callback_px, (self, context), 'POST_VIEW') I was considering not to commit this patch due to it not covering all OpenGL new methods. But frankly it's not the first time bgl is expanded upon individual needs (guilty of that myself). If a python developer knows enough to use OpenGL and need new functions, s/he should also be able to patch Blender for that, so I see no problems here. Another solution is to move to PyOpenGL or similar any soon. glShaderSource implemented differently than opengl standards. It's taking one source at a time (instead of an array of sources). This is similar with PyOpenGL solution. glActiveTexture glAttachShader glCompileShader glCreateProgram glCreateShader glDeleteProgram glDeleteShader glDetachShader glGetAttachedShaders glGetProgramInfoLog glGetProgramiv glGetShaderInfoLog glGetShaderiv glGetShaderSource glGetUniformLocation glIsProgram glIsShader glLinkProgram glShaderSource glUniform1f glUniform2f glUniform3f glUniform4f glUniform1fv glUniform2fv glUniform3fv glUniform4fv glUniform1i glUniform2i glUniform3i glUniform4i glUniform1iv glUniform2iv glUniform3iv glUniform4iv glUniformMatrix2fv glUniformMatrix3fv glUniformMatrix4fv glUniformMatrix2x3fv glUniformMatrix3x2fv glUniformMatrix2x4fv glUniformMatrix4x2fv glUniformMatrix3x4fv glUniformMatrix4x3fv glUseProgram glValidateProgram

All Image source objects now support the buffer interface which allows to create memoryview objects for direct access to the image internal buffer without memory copy. The buffer format is one dimensional array of bytes with 4 bytes per pixel in RGBA order. The buffer is writable, which allows custom modifications of the image data. v = memoryview(source) A bug in the Python 3.1 buffer API will cause a crash if the memoryview object cannot be created. Therefore, you must always check first that an image data is available before creating a memoryview object. Use the new valid attribute for that: if source.valid: v = memoryview(source) ... Note: the BGL buffer object itself does not yet support the buffer interface. Note: the valid attribute makes sense only if you use image source in conjunction with texture object like this: # refresh texture but keep image data in memory texture.refresh(False) if texture.source.valid: v = memoryview(texture.source) # process image ... # invalidate image for next texture refresh texture.source.refresh() Limitation: While memoryview objects exist, the image cannot be resized. Resizing occurs with ImageViewport objects when the viewport size is changed or with ImageFFmpeg when a new image is reloaded for example. Any attempt to resize will cause a runtime error. Delete the memoryview objects is you want to resize an image source object.

bgl new methods (for glsl shaders - #version 120) ** I did not update rst docs. I will post on the quick-hack list. If no one volunteers to do it, I have it done before next release. ** this patch add the barebone functions to do glsl shaders in an addon. For simplicity sakes it supports old GLSL, but not all the new modern methods (glBindFragDataLocation, ...). It should be enough to make an addon to help with bge 2d filters. I'm using this with a 3dview callback and it's working nicely: self._handle = context.region.callback_add(draw_callback_px, (self, context), 'POST_VIEW') I was considering not to commit this patch due to it not covering all OpenGL new methods. But frankly it's not the first time bgl is expanded upon individual needs (guilty of that myself). If a python developer knows enough to use OpenGL and need new functions, s/he should also be able to patch Blender for that, so I see no problems here. Another solution is to move to PyOpenGL or similar any soon. glShaderSource implemented differently than opengl standards. It's taking one source at a time (instead of an array of sources). This is similar with PyOpenGL solution. glActiveTexture glAttachShader glCompileShader glCreateProgram glCreateShader glDeleteProgram glDeleteShader glDetachShader glGetAttachedShaders glGetProgramInfoLog glGetProgramiv glGetShaderInfoLog glGetShaderiv glGetShaderSource glGetUniformLocation glIsProgram glIsShader glLinkProgram glShaderSource glUniform1f glUniform2f glUniform3f glUniform4f glUniform1fv glUniform2fv glUniform3fv glUniform4fv glUniform1i glUniform2i glUniform3i glUniform4i glUniform1iv glUniform2iv glUniform3iv glUniform4iv glUniformMatrix2fv glUniformMatrix3fv glUniformMatrix4fv glUniformMatrix2x3fv glUniformMatrix3x2fv glUniformMatrix2x4fv glUniformMatrix4x2fv glUniformMatrix3x4fv glUniformMatrix4x3fv glUseProgram glValidateProgram
