Real-time drawing technique for textured surface based on multi-projector system

With the development of the hardware performance of projectors and techniques on computer graphics, projections are used on more common surfaces so as to provide vivid and shocking visual effects. A new method that employed multi-projector system and interactive flat devices to modify the appearance of textured surface in real-time was introduced. On the basis of analyzing the color modeling of the system, an algorithm which recovered radiometric parameters and distributed the projection energy properly was presented. Efficient interactive-rendering pipelines were developed to insure that newly designed patterns could be projected on surface of objects without geometry and radiometric distortions. Experimental results show that the proposed method could improve the system accuracy of compensation while enlarging the system intensity range. Interaction, drawing and rendering modules of the system work synchronously to compensate the target appearances in real-time.
