1) projection of exposed surface
暴露弧投影
2) exposure arc
暴露弧
3) circular projection
圆弧投影
1.
This paper applies the principle of circular projection in finding intersection points between lines and revolved surfaces, with the intersecting problem of the line and the surface in 3D space converted to that of a hyperbola and a surface s contour line in 2D plane.
本文将工程图学中的圆弧投影原理应用于直线与回转面的交点计算 ,把空间线面的求交问题转化为平面上二次曲线与回转面轮廓线的求交 ,不仅提高了计算效率 ,而且几何意义清楚 ,算法可靠 ,对于无交点和多交点的情况能够一次判别出
4) circular arc projection method
圆弧投影法
1.
This paper proposes the circular arc projection method for drawing intersection lines of some objects with curved surface, which would sometimes be more convenient than orthogonal projection method for doing the same thing.
本文提出了利用圆弧投影法,求某些曲面立体的相贯线的作图方法,这种方法有时比正投影法更为方便。
5) arc-radius projection
弧半径投影
1.
Multi-object detect method based on arc-radius projection;

6) arc light projector
弧光投影器
