Abstract:

A strategy of designing the visual measurement instrument software, making use of the graphics card’s parallel processing abilities to decrease the overhead of processing massive data, modeling and rendering 3D graph as well as implementing interaction, is proposed in this paper. Based on Direct3D11’s Compute Shader, the instrument software is designed to rapidly achieve preprocessing mass measurement data, modeling 3D graph, pushing render implementing in GPU. And a software model is built to pick up a point on 3D model with mass vertexes implementing in GPU also, with which the interactive speed is increased sharply. The high implementing efficiency of the visual measurement instrument software is verified through experiments. The designing strategy provides a valuable technical path for making the best of hardware capabilities of the measurement instruments’ hardware, reasonably balancing the overhead of CPU and GPU, and then improving the overall implementation efficiency of the instrument.
