3.2 Rendering Techniques of
Chinese Ink Landscape
Painting
The above texture synthesis algorithms are all output images with
regular contours, which are just the preparation stage of digital ink
landscape painting simulation. If these textures and stone models are
directly used for texture mapping, only ordinary mountain and stone
textures can be produced, and the effect of incisive ink and vivid charm
cannot be achieved. Because the shape of the rocks in freehand landscape
painting is both imaginary and realistic, it will produce an effect of
misty rain and misty sky. The synthetic texturing texture must produce a
fusion effect of texture and mountain stone adaptively according to the
virtual and real effect of mountain stone. Therefore, we propose to
introduce the concept of an alpha mask channel in the synthesis process,
thereby realizing the virtual fusion effect of the model inside the
irregular stone contour and the texturing texture.
