Plot 3d closed surface with sparse data
显示 更早的评论
Hello,
I am trying to plot a heart, chest , lung etc, surface with matlab. I have the scattered data, and the clockwise arrangemnt of triangles, by this I mean I have the nodes of each corner of each triangle, the list looks like this,
for the nodes: x y z 1 0.0473 0.0409 0.0428 2 0.0856 0.0285 0.0068 3 0.0724 0.0755 0.0081 4 0.0178 0.0815 0.0118 5 0.0746 0.0033 -0.0366 6 0.0896 0.0546 -0.0355 and for the triangles node 1 2 3 1 50 51 144 2 50 144 140 3 140 144 145 4 140 145 141 5 141 145 146 6 141 146 147
Is there some way to plot the triangular surface in matlab with just one color?. When I call delanuay the mesh is different from the defined one by this list, and the color depends on the hight, I have not been able to plot the whole surface with just one color.

You feed it the triangulation faces and vertices and it draw them
Did you open the doc?
