Image drawing method performed by remote-side apparatus and local-side apparatus

Abstract

An image drawing method performed by first and second computers is provided. The image drawing method includes: transmitting, by the second computer, a streaming video that includes a pen stroke image generated by a first rendering process; generating, by the first computer, a pen stroke image by performing a second rendering process, which is shared with the first rendering process, in parallel with the first rendering process; receiving, by the first computer, the streaming video from the second computer via communication that incurs a delay; compositing, by the first computer, the pen stroke image into the streaming video; and outputting, by the first computer, the streaming video. The image drawing method enables alignment of appearances between a provisional image and the pen stroke image that appears within the streaming video.
