RGL plot : lighting problem when triangle3d and persp3d are used in the same plot
...(1,NA,NA,NA),c(5,3,NA,NA),c(4,2,9,NA),c(8,6,5,11))
x=1:4
y=1:4
persp3d(x,y,z,color="gray")
The two extreme points are not plotted (value=1 and value=10). It seems
because the half of the matrix have 'NA' and perp3d need planar
quadrilateral face. So I decided to use the function triangle3d to
integrate these points into the scene.
So, for the first point I did :
triangles3d(x=c(1,2,2),y=c(1,1,2),z=c(1,5,3)) and it worked
But a problem remains because the light movment on this triangle looks
independant and I did not find how to solve this issue.
How can I prefectly integrate this...
