3.2.2 Texturing rendering synthesis of ink Mountain stone
Based on the above, we carry out texturing rendering synthesis of 3D ink mountain stones with the style of splash-ink effect. This synthesis is done in Maya’s internal 3D rendering engine. We only need to input the texturing image synthesized above and define the rendering index of the stone model stacked with particles. The system will automatically generate the mask image with alpha channel and finally render and synthesize the complete freehand landscape painting effect map. Figure 7 shows the freehand brushwork landscape painting effect of different texturing methods by using the band folding texturing map and under the framework of unified rock modeling and alpha mask channel rendering image. Figure 8 shows the work generated by this technology (the magnified effect of Figure 7-D).
