In other words the user - should have total freedom. - - </p><p> GridFlow follows that philosophy: it first defines elementary - mathematical operations. Those can in turn be used as simple - visual effects or be combined to produce more complex effects. - - </p><p> The strategy followed by most video plugins for PureData and MAX/MSP, is - to provide the user first with constructs for manipulating video - streams at a fairly high level. The strategy put forward by GridFlow - is different. - - </p><p> It can be said that in all those video plugins there are three layers: - the first, the low level, is not accessible to non-programmers (and fairly - difficult of access even to programmers); the second, mathematical, where - one needs not to be a C++ programmer, but still requires a good - understanding of how numbers and pixels and colours and geometry work; and - a third level that looks more like the software an artist would like to - use. - - </p><p> In other video plugins there is a fairly low emphasis on the second - layer. In GridFlow that layer is very strong and opens many possibilities. - Even though the third layer in GridFlow is not as developed as it could, - the second layer may be used to produce third-layer object classes much - more quickly. - - </p><p> GridFlow provides a unifying view of multimedia information. Several - kinds of data -- raster graphics in any number of channels, coordinate - transforms, matrices, vectors -- may all be represented by <b>Grids</b> - (also known as multi-dimensional arrays). Grids exist in several ways: they - are usually streamed from object to object, but they can also be stored in - memory, stored into a file, sent through the network. - - </p><p> In short, GridFlow is a whole new world of possibilities for - the multimedia artist and programmer. - - </p><p>- matju</p><br> -</td></tr> - - <tr><td bgcolor="black"><img src="images/black.png" height="2" width="1"></td></tr> - <tr> - <td width="82%"> - - <p> Here is an example of how things work in GridFlow.

The channels, however, - are more limited in number. Usually it's three: Red, Green, Blue. - - </p><p> A coordinate transform, when specified pixel by pixel, may be a - three-dimensional Grid in which the two "channels" are Y and X, - representing row-and-column positions in a separate picture. - - </p><p> Other shapes of grids could be designed to represent various things; - for example, configuration for blur effects. Grids could be useful for - things not directly related to raster pictures (e.g. sound recordings). - Those are all kinds of things you could actually develop <i>within</i> the - PureData / GridFlow framework.
