Messages and attributes common to the GL group Jitter GL objects have a common set of attributes for how to do their 3D rendering, and messages related to drawing. This includes things like position, rotation, scaling, blending mode, texture, lighting, material properties and other useful tasks. Rendering context name Explicitly sets the OpenGL rendering context by name. If this is absent, the Jitter GL object will use the next higher jit.gl.render or jit.gl.node object in the patcher hierarchy as the rendering context. Equivalent to the draw message. Equivalent to the draw message. Draws the object in the named drawing destination. If the matrixoutput attribute is supported and set to 1, the geometry matrices are sent out the object's left outlet. Draws the object in the named drawing destination. If the matrixoutput attribute is supported and set to 1, the geometry matrices are sent out the object's left outlet. Equivalent to draw with the inherit_all attribute set to 1.
